Abstract: Theoretical foundations for research included the estimations of reference evapotranspiration (ETo) in the midmost Euphrates region and southern Iraq by applying seven mathematical models as well as CROPWAT 8.0 and CLIMWAT software using two sets of climatic data for periods 1970 - 2002 and 2004 - 2010.The results could be summarized as follow : - 1. The annual mean of ETo calculated by the Penman - Monteith equation (PM) for the meteorological stations of Nasiriya, Amarah, Semawa, Najaf, Diwaniya and Kerballa were (6.00, 6.20, 5.92,5.97,6.13,5.74) mm day - 1 respectively, during the first measurement period, and (6.47, 6.08, 5.86, 5.98, 6.13, 5.65) mm day - 1 respectively, during the second period. Also, the ETo estimated by CROPWAT 8.0 and imported by CLIMWAT software have showed the same trend of PM calculations with overestimate reached (6.10, 5.93) % during the first and secondperiods for CROPWAT 8.0 software, and underestimate for ETo reached 8.16 %during the first period for CLIMWAT software compared to PM calculations.2. The statistical criterions for evaluating the performance of six empiricalequations of the original versions were compared with the Penman - Monteithequation revealed that the variations in their performance with relativelypreference for temperature - based equations in comparison with radiation - basedequations. Blancy - Criddle (1950) equation (BC) has proved superiorperformance in Nasiriya, Semawa, Najaf, Diwaniya and Kerballa stations duringboth periods, also in Amarah station during the second period and declining itsperformance for the benefit of Kharrufa equation (1985) (K) during the firstperiod of measurement.3. The calibration process of the six empirical equations including : Hargreaves - Samani (1985) (HS), Makkink (1957) (M) , Priestley - Taylor (1972)(PT),andHargreaves (1975) (H) in addition to BC and K equations were made bysubstituting recalibrated constant values for the original constant values afterthese constant had modified to fit PM calculations and it used a set of statisticalcriterions to verify the validity of calibration and its ability to reduce theestimates errors compared to the original formulas. As the indices ofconcordance (D), confidence (C), correlation (r) and regression (R2) togetherwith the Nash - Sutcliffe Efficiency(NSE), standard deviation ratio (RSR). meanabsolute error (MAE), root mean square error (RMSE), relative error (RE)indicators and the ratio between both average estimations of ETo (r) are used toassess the validation of calibration and optimization which revealed thatconfidence became high in modified equations with reducing the estimation errorof ETo due to approach the values of these criterions from optimal value, then,they had improved efficiency of the six equations to simulate the values of EToare more accuracy than original formulae.4. The proposed new constants for the estimation of the ETo with : BC was 1.37for the time periods from January to April and 1.39 for May to December insteadof the original constant 1 : 41, HS was for the time periods from Octoberto March and for April to September instead of the original constantb0.0023, K was for June - July and for remained months instead of theoriginal constant 0.34, M are for the time periods from November to Mayand for June to October instead of the original constant 0.61, the equationsPT and H were 1.96 and 0 0.0165 for the period of December - May and 2.61and 0.0178 for the period from June to November instead of the originalconstants of 1.26 and 0.0135 respectively and equationsThe side applied to the study has included the implementation of the fieldexperiment for the cultivation of sunflower crop through the loop spring 2013 inprivate farm lies according to the geographical positioning system (GPS) withinthe coordinates (606,366.3437642), (606320, 3437729), (606353, 3437749),(606400, 3437660), is located in Batah town, Thi Qar province, at a distance of 17km west of the city of Nasiriyah, up 5 meters from the sea surface. The mainobjective of experiment included the following : i. Measuring ETo for the study through the crop growing seasonii. To determine the crop coefficient (Kc) and the actual water consumption(ETa) of sunflower crop in the Batah areaiii. . To asses effect of irrigation scheduling and fertilizer application as well astheir combinations on the growth indicators, nutrient uptake, dry matter,crop yields, the crop water use efficiency and water productivity.iv. Evaluating impact of irrigation scheduling and fertilizer application besidestheir combinations on some of soil physical properties at the end season.A field experiment was carried out using factorial experiment in a randomizedcomplete block design (RCBD) Layout with three replications in two factors, nineirrigation Scheduling treatments were assigned to the main plots and four fertilizertreatments were assigned to the subplots. Sunflower seeds (flame) were planted onMarch 23 with plant density 61538 plant ha - 1; the harvest operation was conductedon 18 / July / 2013.The irrigation Scheduling was achieved based on replenish root zone to theborders of field capacity when it reach the percentage of management allowabledepletion (MAD) identified about 55% of total available water (TAW), taking intoaccount the diversity of the effective depth of the root zone according to the stagesof growth, . The experiment involved Irrigation scheduling of the sunflower basedby calculating ETa using Kc which adjusted in situ multiplying by ETo thatestimated by PM equation (S1) ,original BC equation (S2) and adjusted K equation(S3) using meteorological data for real time that collected from agrometeorologicalstation nearby the field. PM equation (S6) using historicalmeteorological data and from pan evaporation with applied (FAO 56, 1998) tocalculate pan coefficient (S4). Whereas, irrigation Scheduling based on soil waterbalance according to daily measurements of soil moisture and adjusted daily onthe basis of changes in moisture content (soil water balance) (S5), fixed irrigationinterval and variable irrigation depth (S7), different irrigation interval and variableirrigation depth (S8) and soil water balance for bare soil (S9). Also the studyincluded four fertilization treatments were used ( F : mineral fertilizer, C : Compost,M : mineral fertilizer + Compost , N : non fertilization). The results showed thefollow : c1. The maximum value of ETo during season growth of sunflower crops accordingto field measurements has increased significantly when using evaporation pan,which gave the highest average rate of 8.81 mm day - 1 in comparison with PMequation that recorded the lowest value of ETo with mean equal to 8.00 mm day - 1,while BC and K gave 8.66 and 8.14 mm day - 1 respectively.2. The converged seasonal mean of Kc value for sunflower crops during growthseason were 0.864, 0.862, 0.863, 0.861, 0.862, 0.862, 0.861, 0.862 for S1 - S8treatments respectively, while the Kc varied in different stages of growth, thehigher value of Kc was 1.213 observed during the flowering stage, followed bytwo phases of vegetative growth and maturity with mean 0.796, 0.494respectively, whereas the lowest values (0.350) was recorded in the initial stage3. The ETa values were variable with various irrigation Scheduling treatments,the treatments (S1 - S8) gave mean ( 876.86, 938.98, 885.57, 943.40, 898.47,949.05, 835.61, 839.76) mm Season - 1 respectively, the mean values of ETa aredistributed as 52.28% during flowering stage, 23.38% through maturity, 18.97%during vegetative growth stage and 5.36% in the initial stage4. The Irrigation scheduling of the sunflower based on S5 treatment caused toincrement of water consumption by transpiration during flowering stage to reach83% from total ETa depth, whereas The Irrigation scheduling based on S7treatment caused to increment of water consumption by evaporation during thesame stage to reach 29% from total ETa depth.5. The results demonstrated that all Irrigation scheduling have been showed astrong relationship with water balance measurement (S5), by R2 is greater than0.91 and r greater than 0.95, also, the results showed there was a preference to therevised K equation to calculate ETa of sunflower crops in the region according toindicators of regression model each of the R2, slope and intercept which amountedto 0.9395, 0.9875, - 0.0144 respectively.6. The overall mean of net irrigation depth was 874.6 mm season - 1 ranged from941 mm season - 1 for S4 treatment to 800 mm season - 1 for S7 . the addition ofwater was 14 applications for S1 - S4 treatments and 15, 13, 12 applications for S5,S8, S7 respectively.7. The lowest nitrogen concentration in the leaves of Sunflower crops duringflowering stage related to decrease water supply at S7 (27.69 g kg - 1) , then, itincreased to maximum value ( 31.48 g kg - 1) when irrigation Scheduling based onS1 followed by S3, S5, S2, S4 treatments,. As respect with maturation stages theS5 treatment gave maximum mean (26.81 g kg - 1) was significantly superiorcompared to all treatments except S1 and it gave increment in nitrogenconcentration equal to 22% in comparison with S8 which recorded lowest nitrogenconcentration (21.94 g kg - 1). The results showed the F treatment was significantlysuperior followed by M treatment which gave average 34.43, 33.42 g kg - 1 duringflowering stage and 28.69, 26.48 g kg - 1 during maturation stage respectively.8. Increasing irrigation depth due to an application S4 and S6 treatments andIncreasing the irrigation frequency for S5 treatment led to significant increment inthe bulk density for 0 - 15 cm depth with mean 1.393, 1.384, 1.386 M m - 3respectively, the bulk density decreased steadily with decreasing of irrigationddepth and irrigation interval until reach their lowest level (1.350 M m - 3) at S7treatment. The bulk density was significantly decreasing when C and M treatmentswere applied with means of equal to (1.362, 1.364) M m - 3 respectively, atmagnitude 1% higher than their initial values. Also the results showed theirrigation scheduling treatments and fertilizer application as well as theircombinations failed to exhibit any significant influence on bulk density for depths15 - 30 cm and 30 - 45 cm.9. The results showed a significant increase in the soil penetration resistance forsoil with high watery supply (S4 and S6), while that status is significantlydecreased under treatment of low watery supply (S7, S8 and S1), the soils withmedium watery supply causing the pattern moderate between the two, also, thisepithet is significantly reduced when you add compost with an average of 708.09kPa, while there was a significant increase resulted from control treatment andaddition of chemical fertilizer alone, the proportion of 31.81 and 18.41%sequentially compared with the addition of compost.10. The results showed the possibility basic infiltration rate for most treatmentsunder the category (moderately slow) according to Landor (1991), by the mean ofbasic infiltration rate was 1. cm h - 1 ranged between 0. to 3. cm h - 1, whereasbasic infiltration rate for S4N and S9 decreased to 0.6 , 0.51 cm h - 1 respectively,thus it can be classified into (slow) while it increased greater than 2.0 cm h - 1 forS1C, S1M, S2M, S5C, S7F, S7M,S7C, S8M treatments which refer to moderateinfiltration rate according to the same classification . C and M fertilization led toimprove soil physical properties, which in turn positively affected the infiltrationrate with increment in magnitude (5 , 56) % respectively, compared to Ftreatment.11. Treatment of F gave a significant superior in most morphologicalcharacteristics and yield components, the efficiency of F treatment for productionwas 37.45 % followed by M and C treatments were achieved 24.66, 19.24 %respectively, compared to N treatment.12. Treatment F achieved highest yield of grains 1945.80 kg ha - 1, an increasing was24.32% in comparison with N treatment which gave lowest yield of grains reached1367.24 kg ha - 1, also there were a significant increase in crop water use efficiencyand water productivity are associated with application of F and M fertilization13. The productivity characteristics of sunflower were significantly affected byirrigation Scheduling treatments, The highest seed yield 1893.8 kg ha - 1and thehighest dry matter 5246.2 kg ha - 1were obtained under S5 treatment, while the S7treatment recorded lowest values of these indicators (1512.5 and 3765.4) kg ha - 1 respectively,14. The application of Irrigation scheduling based on S5, S1 and S3 treatments achieved a significant increase in crop water use efficiency and water productivity, the mean of first parameter was (0.219, 0.216, 0.216) kg m - 3 respectively, and themean of the second parameter was (0.228, 0.220, 0.219) kg m - 3 respectively.

Abstract: ditch opener and manure laying machine was designed and manufactured in the agricultural machines and equipment dept., Agriculture college, Basrah university in 2015. This machine was evaluated to determine its mechanical performance and its ability in laying manure in ditches under the soil surface as well as the effect of the added manure on the soil physical and chemical properties, corn crop growth and production parameters.The machine consists of a frame, manure tank, chemical fertilizers tank, subsoiler for soil disturbance down to 80 cm, two boards for soil digging out to open the ditch , two boards to return the soil to ditch to bury the manure , manure and chemical fertilizers feeding mechanisms and blades for manure mixing with the soil. Also its provide with two pipes to transfer the chemical fertilizers to the soil and a petrol engine to operate the two feeding mechanism.The machine disturbed the soil by the subsoiler and digging different ditches of different depths by two boards . In additional to that it can lay the manure at different levels in the opened ditches using the feeding mechanism and thereafter buried the manure in the soil . The manure can be laid under the soil as separate layer or mixed with soil using the mixing blades.Three experiments were conducted to evaluate the machine performance. These experiments are : (1) - Laboratory experiments were conducted to study the effect of the machine forward speeds (0.32, 0.46 and 0.63 m sec - 1), manure feeding mechanisms rotating speeds (360, 440, 560, 710 and 880 rpm) and two manure feeding openings areas (0.024 and 0.048 m2) as well as the interaction of the above parameters on the amount of the manure per hectare (ton ha - 1). These results were analyzed using CRD and the statistical program (Genstat). Mean results were compared using least significant difference (RLSD) at 0.05 level.The results showed the manure amount per hectare significantly increased as the rotating speeds of the feeding mechanism increased,Bthe forward speeds decreased and the feeding opening areas increased. The highest value was recorded for forward speed of 0.32 m sec - 1 , rotating speed of 880 rpm and feeding open area of 0.048 m2. These means are 64.17, 62.06 and 54.06 ton ha - 1 respectively. while the forward speed of 0.63 m sec - 1 , rotating speed of 360 rpm and the feeding open area of 0.024 m2 gave the lower values which they are 26.91, 30.04 and 33.75 ton ha - 1 respectively. Also, the forward speed of 0.32 m sec - 1 , the rotating speed of 880 rpm and the feeding area of 0.048 m2 recorded the highest amount of manure per hectare (110.00 ton) while the forward speed of 0.63 m sec - 1 , rotating speed of 360 rpm and manure feeding area of 0.024 m2 recorded the lowest value of manure per hectare (4.00 ton).(2) - A field experiment was conducted in silty loam soil in the agriculture college field at Garmit Ali location to study the effect of the implement operation depths (10, 20, 30, 40 and 50 cm), the angle between the soil digging out boards (45⁰ and 60⁰) two soil types namely cultivated soil before one year and uncultivated soil and their interaction on the implement mechanical performance parameters . These parameters are the draft force, soil disturbed area and the energy utilization efficiency (EUE) as well as the draft force requirement of the implement units (subsoiler, ditch opening boards, soil returning boards and soil mixing blades). The results were analyzed using RCBD. The analyzing was carried out by the statistical program (Genstat). Mean results were compared using RLSD at probability level of 5% , and showed the followings : (2 - 1) - The draft force, the disturbed area and the energy utilization efficiency increased significantly when the operating depth increased from 10 to 50 cm. The amount of the increase is 26.66 kN , 0.4111 m2 and 7.67 m3 mJ - 1 respectively.(2 - 2) - The angle between the opening boards of 60⁰ significantly surpassed angle of 45⁰ in increasing the draft force, the disturbed area and EUE. The percentage of increase is 12.55 , 21.93 and 10.85 % respectively.C(2 - 3) - The draft force decreased while the disturbed area and EUE increased by 16.30, 14.91 and 20.72 % in the disturbed soil compared with undisturbed soil respectively.(2 - 4) - The draft force requirement of the subsoiler was higher than that for the other implement parts. The share of the draft force requirement of the subsoiler was 60 % out of the total draft force requirement of the implement while it was 26, 9 and 5 % for the ditch opening boards, the soil returning boards and soil mixing blades respectively.(2 - 5) - The draft force requirement of all implement units increased significantly with implement operating depths and the angle between the ditch opening boards and it was higher in the uncultivated soil compared with the cultivated soil. The draft force requirement of the soil returning boards and the soil mixing blades in both soil types was not significantly different.(3) - Another field experiment was conducted in the field of the agriculture college at Garmit Ali location in the season of 2015 in a cultivated soil of silty loam texture. The aims of the experiment were to study the effect of the added manure level (0, 20 and 40 ton ha - 1), the depths of added manure (10, 20 and 30 cm) and the methods of the addition (subsoil layer and mixing with soil) and their interaction on the soil properties and corn crop (Zea mays L.) growth parameters and yield at the end of the growth season.The soil was plowed and harrowed (soil clods breaking down). The manure was added thereafter by the implement in the soil according to the studied treatments. The corn seeds were sown in rows at 1/7/2015. The drip irrigation method was used to irrigate plants until the end of the experiment 10/10/2015. The other agricultural operations were conducted according to methods used in the around area.Soil and plants samples were collected for analysis and the corn seeds yield was calculated at the end of the growth season. The measurements included soil bulk density, soil moisture content, soilDsalinity, soil pH, the dry weight of the shoot, N, P, K uptake in shoot and the total seeds production.The split - split plot in RCBD design was used to analyze the means using Genstst program. Mean results were compared using RLSD at probability level of 5 %, and showed the followings : (3 - 1) - The manure level of 40 ton ha - 1 surpassed the other two levels (0 and 20 ton ha - 1) in giving higher values of soil moisture content, higher uptake of N, P, K, a greater amount of dry weight and total yield while it gave lower soil bulk density, soil salinity and soil pH.(3 - 2) - Increasing the depth of added manure from 10 to 30 cm with the mixing method lead to significant increase in the soil moisture content, uptake of N, P, K, the dry weight and the total yield production. Whereas the soil bulk density, soil salinity significantly reduced while the soil pH was not significantly affected.(3 - 3) - Mixing of 40 ton manure ha - 1 at depth of 30 cm gave the highest crop growth and yield production which they are 13.94 and 6.75 ton ha - 1, respectively.

Abstract: A field experiment was conducted at Al - Daire site 40 km north of center Basrah Governorate .The study was conducted to investigate the effects of different nitrogen fertilizer levels on dry matter accumulation, (N, P, K) uptake, distribution in different parts of three cultivars of wheat plants and their yield during two seasons (2011 - 2012 & 2012 - 2013).The experiment was split - plots in R.C.B.D design with three replicates, Nitrogen rates (0, 60,120 and 240Kg ha - 1 occupied the main plots, while (IPA - 99, Abu - Graib and Latifia) Cultivars Occupied the sub - plots. Samples of wheat plants were collected at 10 growth stages : seedling stage, tillering (main shoot and 1 tiller), tillering (main shoot and 4 tillers), stem elongation, booting, 50% of spike emergence, 50% flowering, milk stage, dough stage and maturity. Each plant sample was separated into different plant parts : blades, sheathes, stems, flag leaves, spikes and seeds. These parts were dried at 70°C and dry weight of each part was recorded and sub sampled for chemical analysis of N , P , and K. Growth parameters (No. of day till 50% flowering , No. of day from 50% flowering to Maturity , flag leaf area , plant height, spike length and No of tillers m - 2) , yield components (No. of spike m - 2, No. of grain in spike and weight of 1000 grain ),grain yield, biological yield, harvest Index, grain protein percentage and nitrogen use efficiency were also studied.Results showed that dry matter accumulation in plants of all cultivars did not differ at early growth period, While after the growth stage of 50% flowering plants dry weight of Cv.IPA - 99 was higher than other cultivars, This difference in dry weight continue till maturity stage at which total dry weight were 14473.58, 13373.96 and 12743.59 Kg ha - 1 for IPA - 99, Abu - Graib - 3 and Latifia respectively.Dry matter yield were not affected by N levels during the early growth period ,then after dry weight of plants increased as N rates increased ,total dry weight were10752.61, 12737.49 and 15347.10 Kg ha - 1for 0, 60 , 120 Kg Nha - 1 respectively, with no differences between 120 and 240 Kg Nha - 1 levels.Dry matter of plant parts differed among cultivars, with IPA - 99 having the highest results. Increasing nitrogen rates increased weight of different plant parts, but did not influence the relative proportion of each plant part for all cultivars.IIResults also showed reduces in dry weight of different plant parts(except grains)after reaching a maximum weigh at dough stage for Spikes, and 50% flowering for the other parts. The highest decreased was in blades and lowest in sheathes. The application of N fertilizer decreased translocation of dry matter from plant parts to grains. Data showed that no differences in nutrient uptake were observed for cultivars till ending of tillering stage, but after this stage IPA - 99 cultivar showed highest uptake till the end of the season. Nitrogen uptake was157.68,136.72,124.51 Kgha - 1 ,P uptake 19.70,16.93,15,67 Kg ha - 1, K uptake136.30,121.10,112,60 Kg ha - 1 for IPA - 99,Abu - Graib - 3 and Latifia, respectively.Increasing N rate increased nutrient uptake of different plant parts, but did not influence the relative proportion of each plant part for all cultivars.uptake of N, P, and K for all cultivars and nitrogen rates declined as the season progressed, this decline differed among nutrients and plant parts.Grain contained 59.20, 79.00 and 7.45% of total nutrient N, P and K uptake, whereas vegetative parts contained 40.80, 21.00 and 92.55% of total nutrient uptake, respectively.Cultivar IPA - 99 resulted in highest grain yield among studied cultivars. Increasing N rate from 0 to 120 Kg N ha - 1 only increased grain yield, the rate 240 KgNha - 1 did not affect yield significantly as compared with that of 120 Kg N ha - 1.Results also showed a significant interaction between Cultivars and N rates. The highest grain yield obtained at treatment IPA - 99×240 Kg N ha - 1with no significant differences than IPA - 99×120 KgNha - 1.Results indicated that highest nitrogen use efficiency (66.23%) was found in plant of IPA - 99 cultivar, whereas, the lowest efficiency (47.37%) was found in plant of Abu - Graib - 3 cultivar. At all cultivars increasing N rates to 240 KgNha - 1 decreased nitrogen use efficiency.Therefore it can be concluded that 120 Kg Nha - 1 can be recommended as the best rate for N to all cultivars under similar growing conditions

Abstract: Thirteen water sample of Shatt Al - Arab river and its tributaries were collected starting with Madania at (north of Basrah ending with Al - Fao south of Basrah) according to the following areas (Medania , Gurna , Sharesh, Deyar/ near paper plan, Hartha (near thermal electric station), Garmat Ali (Basrah university), Tenoma/Sahehia , near teaching hospital, Abul - Khaseeb /Hamdan, Abul - Khaseebl Abu - Floose, Sebha, Al - Dora, and Al - Fao. Fifteen well's water sample were collected from Al - Zubair , Al - Berjesia and Safwan during Dec.2014. Chemical and physical properties of water samples were conducted (ECiw), soluble ions (calcium, mangnesium, sodium, potassium, chloride, sulphate, carbonate, bicarbonate, boron, and nitrate), total dissolved solids (TDS), and total hardness. After water sample properties determination, they were classified to three classes according to electrical conductivity (1 - 4, 4 - 8, and 8 - 12) dSm - 1 , and three classes of boron concentrations (< 0.7, 0.7 - 3.0, and > 3.0) mg L - 1 . For the purpore of study of studies filter efficiency, two type of filter were used, mineral filter (sand, charcoal, porcelin, and cement klint dust) and organic filters (rice hust ash, barley straw, sawdust, plam leaf, and poultry rnanure). Two experiments were conducted, one of them laboratory experiment in soil science and water resources laboratories /College of Agriculture /University of Basrah) other was biological experiment in wooden canopy to achieve the objectives of the study.Nine type of mineral and organic types of filters were selected for studying their efficiencies in decreasing water salinity and boron toxicity of Shatt Al - Arab river and Wells, after passing water through them. Chemical and physical properties of water were determined after passing water through filters and water quality was calculated. A number ofBcriteria and international standards were used for evaluation water quality after and before passing through filters.For studying the efficiency of water treatment by the most efficient filters according to laboratory experiment results were rice husk ash, cement klint dust, sand, and control treatment. Biological experiment was conducted by using plastic pots with capacity of20 kg soil according to factorial experiment with three replicates for each treatment with 24 empirical units (2×3×3) (soil * No. of filters * replicates) besides control treatment and six classes of water to be 144 empirical units. Two soils were used one of them from Agricultural field of Agricultural Research Station, and the other from Garmat Ali field during agricultural season 2014 - 2015. Mineral fertilizers were used with rates, 320 Kg N ha - 1as urea (46 % N) with two doses, phosohate fertilizer was applied at rate 90 kg P ha - 1 as concentrated supper phosphate (20.21 % P), potassium at rate of 120 kg K ha - 1 as potassium sulfate (43 % K) one dose at planting. Peatmose fertilizer was applied at rate 2% for all treatment mixing with soils. For getting erough water for irrigation, plastic coloumns wereduplicated in their dimentions for studied filters. Shatt Al - Arab and wells water were passed through most efficient filter besides sand filter separately with equal quantities. Water was collected after one minute to conform the properties of laboratory experiment.Tomato plants (Lycopersiconesculintium M.)were planted on 22/9/2014 and irrigated with water treated with filters besides control treatment at field capacity (20 % for Berjesia Research Station soil) and (30 % for Garmat Ali soil). Leaching requirement was calculated for each treatment. After 176 days, plants were harvested with space 2 cm from soil surface avoiding contamination. Tomato plants were fractionated into three parts, roots, shoots, and fruits. Dry matter of roots and shoot wasBCcalculated. Boron concentrion of (roots, shoots and fruits) was determined. Fruits yied of tomato was calculated. Electrical conductivity and available boron of residual soils in pots were determined after tomato plants growth Period.Results obtained could be summarized as : 1. Adoption of rice husk ash and cemenentklint dust in treatment of Shatt Al - Arab and wells water because of their high efficiency in decreasing boron concentration and water salinity and reuse for tomato plant irrigation and Plants irrigated with water treated with rice husk ash were surpassed over other plants in dry matter and yield, and gave lowest boron concentration in tomato plant tissues for all parts roots, shoots, and fruits. Same treatment gave the lowest concentration residual boron in soil and lowest value of soil salinity as compared with water treated with cementklint dust filter and sand filter besides control treatment.2. loamy sand soil was surpassed over clay loam soil in dry matter and yield of tomato and lowest concentration of boron in their tissues, while clay loam soil was surpassed over loam sand soil in residual boron concentration and soil salinity.3. Results indicated that there were significant differences between type of filters and soil texture in dry matter, yild , boron concentration in roots , shoots, and fruits of tomato plants. Residual boron concentration and soil salinity.4. Results indicated that there was no boron contamination in both studied soils treated with water of Shatt Al - Arab and wells treated with two filters (rice husk ash and cementklint dust)

Abstract: Research were divided into two experiments, field and storage , field experiment was conducted in private orchard at Abu - Alkhasib south of Basrah . Date palm fruits( Phoenix dactylifera L.) cvs. Barhi and Bream were used during the growing seasons 2014 and 2015. The aim of the study was to investigate the effect of spraying chitosan at the concentrations of 0% , 1% , 2% on yield and some physical , chemical and physiological characteristics of fruits. The experiment included 9 trees for both cvs. Complete Randomized Block Design was used with three replicates . The results were analyzed by the analysis of variance of factorial experiment and mean values were compared using the Revised Least Significant Difference Test at 0.05 probability level. The results of study showed significant effect of spraying chitosan at the concentrations of 2% on the most of the studied parameters (fresh weight , size of fruit , yield , water content, total acidity ,tannin and pectin) in addition to delay the ripening and respiration rate of fruits for both cvs. Untreated fruits retain the highest percentage of total soluble solids , total sugars , reducing sugars and total protein. Invertase and cellulase activities decreased in fruits treated with chitosan as compared with untreated fruits which recorded the highest activity of invertase and cellulase for both cvs.Storage experiment was conducted in Al - Moussawi dates factory situated at Abu - Al - Khaseb District , Basrah Governorate to study the effect of some pre and post harvest natural control treatments in improving the qualitative characteristics and storage ability of date palm fruits cvs. Barhi and Bream. Fruits that treated with chitosan at the concentrations of (0, 1, 2) % were harvested in the early morning and carried to Al - Moussawi dates factory. Then every one of the three parts divided into five groups ,the first was treated with ultraviolet light (UV) at the concentration of 1KGY for periods of (0, 5, 10) minutes ,while the second group were treated with (1 - MCP) at the concentration of ( 0,0.5,1) ppm for 24 hour at 0 ºc .third was treated with ozone (O3) at the concentration of 5 ppm for the periods of (0, 0.5, 1) hour ,while the fourth group were soaked in chitosan at the concentrations of ( 0,1,2) % , the fifth were without treatment .Fruits were packed in plastic bags.Both of the two parts were stored at two storage temperatures (room temperature 25±2ºc and freezing temperature - 10±2ºc for three weeks and six months respectively . Storage characteristics were studied before andBduring storage and at the end of storage period . the results can be summarized as follow : 1 - spraying chitosan at the concentrations of 2% in the field reduced the percentage of deteriorated fruit , ripening process, TSS , total and reducing sugars and increased the percentage of water content, sucrose and total acidity in addition to elongation the desirable color of fruits and keeping good flavor and taste for Barhi and Bream fruits until the end of storage period at - 10±2ºc and 25±2ºc for the both of growing seasons 2014 and 2015 .2 - Treating with ultraviolet light (UV) for 5 minutes reduced percentage of decay for Barhi ,whereas fuel west percentage of Bream fruits decay was in fruits treated wish ozone for 1hour for both growing seasons .3 - Treating with (1 - MCP) at the concentration of (1) ppm reduced the progress of ripening and total sugars and increased water content, sucrose and total acidity in addition to elongation the desirable color of fruits and keeping good flavor and taste for Barhi and Bream fruits up to the end of storage period at - 10±2ºc for the both of growing seasons .4 - The percentage of decay of fruits , ripening progress, loss in weight , TSS , total and reducing sugars increased whereas the percentage of water contents, sucrose and acidity decreased with increment of storage period for both cultivars and seasons at 25±2ºc and - 10±2ºc.5 - The interaction between field treatments and storage treatments had significant effect on percentage of fruits decay. Fruits sprayed with chitosan at the concentrations of 2% in the field and treated with ultraviolet light (UV) for the periods of 10 minutes had the lowest percentage of fruits decay for both growing seasons .6 - The interaction between spraying chitosan and storage period significantly effected on studied parameters . Fruits sprayed with 2% chitosan in the field were superior in keeping water content and delaying ripening process but they had the lowest TSS , total and reducing sugar at the end of storage period at 25±2ºc and - 10±2ºc compared with untreated fruit for both cultivars and seasons .7 - The interaction between storage treatments and storage period significantly effected on studied parameters. Fruits treated with (1 - MCP) at the concentration of (1) ppm were the best in keeping water content and delaying ripening process but they had the lowest TSS , total and reducing sugar at the end of storage period at 25±2ºc and - 10±2ºc compared with untreated fruit for both cultivars and seasons .C8 - The interaction among field treatments, storage treatments and storage period had significant effect on percentage of fruits decay. Fruits sprayed with chitosan at the concentrations of 2% in the field and treated with ultraviolet light (UV) for the periods of 10 minutes had the lowest percentage of fruits decay , at the end of storage period at - 10±2ºc for both cultivars and seasons .9 - Gel electrophoresis for protein showed that in Barhi and Bream fruits treated with pre and post harvest natural control treatments and stored at - 10±2ºc , the process of gene expression has occurred , since there was a number of bands , which differed both in number as well in their position on the gel , depending on treatments and cultivar . There was very clear differences between treatments in the number , position and the timing of the appearance of the protein bands for both cvs. during which Bream fruits treated with chitosan recorded the highest number of bands ( seven bands).

The first experiment was carried out during the growing season of 2002 - 2003 in the field of Agricultural Research Center at Al - Twaitha region 30 km Southern east of Baghdad while the second experiments was conducted during the growing season of 2003 - 2004 in the field of College of Agriculture at Abu - Graib 20 km West of Baghdad.A split - split plots design was used with three replications for each treatment. Planting dates (Nov., 15 and Dec., 15) for both season were assigned as the main plot. Irrigation treatments 200, 300 , 400 and 500 mm and cultivars, IPA 95, Abu - Graib 3, Alhashimia and Babylon 113 were considered as sub and sub - sub plots respectively. Results reveled that grain yield significantly reduced with application of water stresses. The reduction increased with the increased water stress in both seasons. The first sowing dates recorded the highest grain yield (5.20 and 5.28 ton/ha in the first and second seasons respectively) in comparison with second sowing dates which gave grain yield of 4.92 and 5.09 ton/ha in first and second seasons respectively. Mean grain yield under water stress was found to be higher in Abu - Graib 3 than the other test cultivars while Alhashimia gave the lowest mean grain yield under water stress. Water stress applied at the second sowing date significantly reduced time required for growth stages, plant height, flag leaf area, tillers number, straw biomass, and yield an yield components in comparison to the first sowing dates due to the high temperature during the second sowing date. Abu - Graib 3 cultivar was found to be the most efficient cultivars in water use (1.62 and 1.66 kg grain/m3 water in the first and second season respectively) and recorded the lowest sensitivity index to water stress in both seasons (0.87 and 0.93 in the first and second season respectively), while Alhashimia cultivar showed the lowest water use efficiency (1.49 and 1.53 kg grain/m3 water in the first and second season respectively), and had the highest sensitivity index to water stress in both seasons (1.12 and 1.07 in the first and second season respectively). The present study revealed the possibility of saving 40% of water with grain yield reduction of 18% of control treatment (500 mm) when sowing started at November 15. This amount of water can be used for cultivation of additional area

Five sampling stations were chosen. Ecological diversity indices were adopted, with a focus on the dietary relations among species of fish larvae and the possibility of dietary overlap within larvae. Two sampling methods were adopted to collect the samples, plankton nets with mesh sizes 100 - 300µm and a wooden quadrate to collect aquatic plants that may exist upon fish eggs and larvae. Water temperature of the studied area ranged form 11.2ºC in January to 33 ºC in August. Salinity ranged form 1.81‰ in December to 3.3‰ in August. Light penetration ranged from 20 cm in July to 150 cm in January. A total of 360 samples were collected, 72 samples from each station. These samples included 7220 fish eggs belonged to three families and 7360 fish larvae belonged to five fish families. The eggs were identified Cyprinidae included Cyprinus carpio and Carassuis auratus, Mugilidae (Liza abu) and Cyprinodontidae (Aphanius sp.). The eggs of L. abu were prevailed at stations 1,3 and 4, and the eggs of C. carpio and C. auratus at stations 2 and 5. The eggs of C. carpio , C. auratus and L. abu were presented in four months ( February - May), and Aphanius sp. from April to July with peak during April. The eggs of L. abu , C. carpio and C. auratus were most abundant during March. Larvae were classified into five families included. Cyprinidae, which included the larvae of C. carpio , C. auratus and A. mossulensis, whereas, Mugilidae included a single species ( L. abu), and Cyprinodontidae, where the larvae were classified to the species level Aphanius sp., Clupeidae represented by Tenualosa ilisha, and Hemiramphidae by Hemiramphus sp.. Larvae of L. abu prevailed on other species in the five stations, and the larvae of C. carpio came in second place in the stations 1,2 and 3. Larvae of Aphanius sp. Occupied second place in station 3 and the larvae of T. ilisha in the second place in station 5. Larvae of T. ilisha appeared during six months (March, April and June to August ) with peak during August in station 4, while the larvae of Aphanius sp occurred at five months (April to August), with peak during April in station 3. The larvae of L. abu , C. carpio and C. auratus occurred in four months ( March to May) , with peak in total number during March at station 3, for L. abu and C. auratus and at station 1 for C. carpio. Larvae of Hemiramphus sp. appeared in August at station 5. The abundance of fish eggs and larvae collected from aquatic plants more than provided by using plankton net, as indicated by the results of statistical analysis there were significant differences between station 1 and stations 2,3,4 and 5 in abundance of fish eggs and larvae which were collected by plankton net, and between station 3 and stations 1, 2 and 5 in the abundance of fish larvae collected from aquatic plant. The diversity index (H') for fish larvae ranged between 0 - 1.068, while the richness index (D) ranged between 0 - 0.884 and the evenness index (J) between 0 - 0.739. Cluster analysis show that the highest similarity in the number of fish larvae between station 2 and stations 3, 2 and stations 4, stations 3 and 4. The highest similarity in the total number fish larvae was found between stations 1 and 5, according the Schoener index. The diet analysis was assessed using points and frequency of occurrence methods. No empty larval stomach were recorded during the study period and there is a high feeding activity and feeding intensity. The result of analyzing stomach contents indicated that the fish larvae were generalized feeders, consumed diatom, algae, detritus, copepoda, daphnia and eggs of molluscs. The larvae of C. carpio and C. auratus feed on diatom, while A. mossulensis, Aphanius sp. and T. ilisha on copepoda. The diversity index of gut content ranged form 1.731 for L. abu to 0.762 for C. carpio. The fish larvae differ in intensity of diet overlap depending on the nature of nutrition, and nine significance diet overlaps between larvae were detected. The significance overlaps ranged form 67.10% to 91.73 %. The highest diet overlap (91.73%) between C. carpio and C. auratus. A very strong diet overlap (101.22) between A. mossulensis and Aphanius sp.. No diet overlap were detected between the larvae of C. carpio, C. auratus, T. ilisha, Aphanius sp and A. mossulensis. The study showed the importance of the northern part of the Shatt Al - Arab River as a breeding and nursery ground for some fish

Data of 23 hybrid cows of different ages and season were used. The cows fed wheat bran and reeds as roughages ad libtum . All measurements were done during 1/12/2006 to 31/12/2007. Data included body, udder and teat measurements and partial milk and total milk yield. Milk yield and its content were also included. The result revealed the followings : 1 - Overall mean of daily, total and corrected for 305 day milk yield were 5.80, 1740.97 and 1883.91kg respectively. Entire trait significantly influenced by lactation stage and season. Corrected milk yield for 305 day was influenced by udder shape, teat open and teat shape. However udder and teat shapes did not significantly affect daily and total milk yield. 2 - Mean of partial milk at 30, 60 and 90 days were 171.98, 415.10 and 656.97 kg respectively. They were significantly influenced by season, udder shape and shape of teat open.3 - Mean of fat and protein percentages and were 3.96%, 3.63% and 5.48 mmol/L respectively. Season and stage of lactation had significant effect on these traits, in contrary to interaction effects.4 - Wood’s (1967) model was suitable to milk yield and its component, as it fitted to all early and late yield data beside differences between actual and expected values were very low.5 - Initial milk yield (first week yield, a) calculated by Wood’s (1967) model was 33.74 kg. Milk increased weekly by a rate of 0.517 kg/week to reach peak production (65.08kg), after that decreased in a rate (c) of 0.059 kg/week. Persistency was 74.22% from peak production.6 - Initial fat and protein percentages and urea content (production of 1st month) estimated by Wood’s (1967) model was 4.023%, 2.89% and 5.31 mmol/L respectively.7 - Initial production (a) was significantly correlated with b and c parameter, persistency and number of weeks at peak ( - 0.48, - 0.68, - 0.61 and - 0.60 respectively).8 - Lactation season significantly affected persistency, peak production and initial production (a) for milk yield and protein percentage.9 - There was a significant positive correlation between milk yield and its component (fat, protein and urea). Correlations among milk yield and its component with blood biochemical parameters were high, significant and positive. They were 0.958, 0.698 and 0.834 between blood urea and milk yield or milk protein or milk urea respectively.10 - Overall mean of body height at neck and tail, body length, diagonal body length, chest girth, abdominal girth and distance between pin bones were 121.04, 147.35, 141.69, 127.17, 188.69, 200.87 and 25.96 cm respectively.

Meikle وP. orientalis (Mill.) Koehne وP. microcarpa C.A.Mey وP. brachypetala (Bioss.) Wallp.. اما في الجانب الكيميائي فقد تم تشخيص عدد من المركبات الفينولية اعتمادا على مركبات قياسية معروفة، اذ اختلفت هذه المركبات في انتشارها باختلاف انواع الجنس التي درست وبينت الدراسة اشتراك انواع الجنس في وجود عدد من هذه المركبات مما يعزز وحدة الجنس وصحة انتماء انواعه اليه، علما بان هذه الدراسة تجري لاول مرة بهذا الشكل لانواع الجنس التي تمت دراستهواقد اعطت نتائج مهمة وحاسمة في تشخيص وعزل انواع الجنس من حيث محتواها من المركبات الفينولية. ودرس التوزيع الجغرافي للانواع النامية بصورة طبيعية في العراق ورسمت خرائط توزيع الانواع على المقاطعات الجغرافية الطبيعية في العراق واظهر النوع P. arabica اوسع مدى للانتشار، بينما اظهر النوعان P. kotschyi (Boiss. Et Hoh.) Meikle وP. carduchorum (Bornm.) Meikle توزيعا ضيقا جدا، وقد قورنت الانواع عدديا لتوضيح العلاقة بينهما، وقد عززت المقارنة العددية صحة تقسيم الجنس الى (3) جنيسات Subgenera وهي Prunus وAmygdalus وCerasus من خلال المخطط الشجيري Dendrogram والمخططات عديدة الاضلاع Polygonal graphs، واخيرا وصفت انواع الجنس التي درست وصفا مفصلا ووضع مفتاح لفصل انواع الجنس | The present work includes a comparative systematic study of (18) Taxa belonging to the genus Prunus L. (Rosaceae) which grown wildly and cultivated in Iraq. Gross and micromorphology, cytology, chemistry, Ecology and geographical distribution were done for all species of the above genus. Iraqi phytogeographical districts were surveyed to detect the distribution of the studied species, and all the specimens collected including those from herbaria were all identified. This study indicates that the flower and fruit characteristics are more stable than others in addition to stem, twigs, leaves and stipules which were used to separate and identified the species of the genus. Palynological study as pollen shape, diameter and configurations have been an aid for identification pollen were found to be tricolporate. The trichomes took a good position among the taxonomic characters of some species of the genus.The anatomy of leaf including petiole, cuticle, venation and wood of all species were investigated. A correlation between these anatomical features, polyploidy and habitat were made too. Variations were distinct among lower epidermal cell shapes of leaf and petiole cross section, shapes and vascular strands, thickness of cuticle and lamina in addition to the shapes of middle vascular bundles of mesophyll. These variation were important in classification of each species into several groups.Haploid and diploid chromosome number was determined for eleven species four of them were recorded for the first time which were Prunus arabica (Oliv.) Meikle, P. orientalis (Mill.) Koehne, P. microcarpa C.A.Mey and P. brachypetala (Bioss.) Wallp. On the chemical side of view phenolic compounds were identified. The distribution of these compound was variable among various species of the genus studied. The geographical distribution and ecology of the species were studied using Iraqi phutogeographical districts, and it was found that P. arabica has a wide range of distribution while P. kotschyi (Boiss. et Hoh.) Meikle and P. carduchorum (Bornm.) Meikle have narrow range of distribution. Prunus species were compared numerically, dendogram and polygonal shapes were also drawn and these shapes confirmed the present treatment of the genus into three subgenera (Prunus , Amygdalus , Cerasus). All the prunus taxa were fully described, key for the species was constructed and represented specimens were given too for each species.

Quercus aegilops ) لواصق في انتاج الالواح الحبيبية المضغوطة .وقد تضمنت الدراسة مرحلتين : المرحلة الاولى تتعلق بخطوات الاستخلاص المختبري والصناعي . ففي القسم الاول تم استخلاص التانينات مختبريا بثلاث درجات من النقاوة باستخدام ثلاث طرق تتابعية للاستخلاص. وقد اظهر الفحص المختبري لقلف نوعي الاشجار العراقية المذكورين انفا اظهر وجود كميات مناسبة من المستخلصات التانينية وبانتاج كاف حيث كانت نسبة المحتوى من التانين هي (15.3 ، 12.65٪ ) للصنوبر والبلوط على التوالي. فضلا عن فاعليتها في الانتاج التجاري والتطبيقي من اللواصق التانينية الملائمة للمنتجات الخشبية. ان طبيعة هذه التانينات والمركبات التي تحتويها تم تحديدها باستخدام تقنية كروماتوغرافيا الطبقة الرقيقة لتشخيص مختلف المركبات وفصلها عن بعضها ، حيث تضمنت تانينات صنوبر بروتيا المركبات التانينية{( - )gallocatechin, ( - )catechin, ( - )epicatechin, (+)afzelechin} ومن تانينات بلوط الاكل المركبات التانينية{( - )catechin, ( - )epicatechin, (+)afzelechin, ( - )epiafzelechin, gallic acid, phloroglucinol, ( - )gallocatechin, ellagic acid} . ويتبين من هذه المركبات ان تانينات الصنوبر متكونة بصورة رئيسة من التانينات المتكثفة وبعض التانينات المتحللة في حين كانت تانينات البلوط متكونة بصورة رئيسة من التانينات المتحللة وبعض التانينات المتكثفة على شكل خليط معقد منهما. اما القسم الثاني من المرحلة الاولى فقد تضمن انتاج مستخلص التانين الصناعي من كلا النوعين من القلف باستخدام طريقة الاستخلاص المائي وباستعمال الهاضم البخاري ، ثم اضيف 0.25٪ من كل من sodium sulphite وsodium bisulphit لزيادة ثباتية المستخلص لحين الاستخدام ، وجرى بعدها تركيز المستخلص في جهاز التركيز البخاري للحصول على مستخلص بتركيز 50٪ من المواد الصلبة ، بعدها اصبح المستخلص جاهزا لتصنيع الالواح في المرحلة اللاحقة . وفي المرحلة الثانية من الدراسة صنعت الالواح بالمواصفات المختبرية ، وقد سبق تصنيع الالواح اجراء عملية كبرتة ومثيلة المستخلص المركز باستخدام 10٪ من مادة بارافورمالديهايد بوصفها مادة مصلبة واجريت الاختبارات على زمن تكون الهلام Gel - time وزمن التشغيل Pot - life وعند مختلف قيم الـ pH ، وظهر ان افضل زمن لتكون الهلام هو 7 دقائق عند pH( 5.5) ، حددت في ضوئها مدة الكبس الحار . ونظرا لاحتواء المستخلصات على نسبة من المواد غير التانينية التي تؤثر سلبا في مواصفات اللاصق ، فقد جرت تقوية مستخلص التانين باللاصق التركيبي يوريافورمالديهايد وبعدة نسب من الخلط لضمان مشاركته لعملية بلمرة التانين وتقويض دور المواد غير التانينية . صنع 180 لوحا حبيبيا بالمقياس المختبري (35×30×1.8 سم ) بمستويين من مصادر التانين ( صنوبر بروتيوا بلوط الاكل ) وخمسة مستويات من نسب الخلط تانين : يوريافورمالديهايد ( 100 : 0 ، 75 : 25 ، 50 : 50 ، 25 : 75 ، 0 : 100 ) وبمستويين من درجات حرارة المكبس (170 ، 190 م ) وثلاثة مستويات من فترات الكبس ( 8 ، 10 ، 15 دقيقة ) . صنعت الالواح تحت ضغط ( 1250 باوند / انج2 ) وبمحتوى من اللاصق 10٪ (بالاعتماد على وزن الحبيبات المجففة بالفرن و50٪ من المواد الصلبة للمستخلص ) للوصول الى كثافة اللوح (0.6 غم /سم3) بسمك (18ملم). ان الصفات الميكانيكية والفيزيائية فحصت طبقا للطرائق القياسية لـ2559 ASTM (1961) . اظهرت النتائج بان الصفات الميكانيكية للالواح (معاملي الكسر والمرونة وقوة التماسك) المصنعة بلاصق تانين الصنوبر كانت افضل من المصنعة بلاصق تانين البلوط. كما اظهرت النتائج امكانية تقوية اللواصق التانينية باليوريافورمالديهايد عند نسبة تانين الصنوبر25 - 50٪ ونسبة تانين البلوط 25٪. وكان لدرجة حرارة المكبس (190 م) الاثر في تحسين صفات الالواح الميكانيكية ولاسيما عند مدة الكبس (10 دقائق)، اذ بلغ اعلى معامل كسر (160.45 و149.75 كغم/سم2) واعلى معامل مرونة (11339.7 و10883.7 كغم/سم2) واعلى قيمة لقوة التماسك (7.33 و6.06 كغم/سم2) للالواح المصنعة بتانين الصنوبر وتانين البلوط على التوالي، وان الالواح المذكورة اجتازت قيم الواح المقارنة ولاقت المواصفات الامريكية 2559 ASTM (1961). كما اظهرت فحوصات الصفات الفيزيائية (النسبة المئوية لامتصاص الماء والانتفاخ بالسمك والتمدد الطولي) سلوك التانينات، والفورمالديهايد ومحتوى المستخلصات من الشمع بالنسبة للصنوبر والاسترات بالنسبة للبلوط بوصفها مواد طاردة للماء. وتساوى النوعان تقريبا في تحسين الصفات الفيزيائية للالواح المصنعة. اذ اظهرت النتائج امكانية تقوية اللواصق التانينية باليوريافورمالديهايد عند نسبة تانين الصنوبر 25 - 75 ٪ ونسبة تانين البلوط 25 - 50 ٪ وكان لدرجتي حرارة المكبس الاثر في خفض المحتوى الرطوبي وزيادة مقاومة الالواح لامتصاص الماء فضلا عن ثباتية ابعادهوالاسيما عند مدة الكبس الاطول 15 دقيقة. اذ بلغت اقل نسبة امتصاص (59.971 و60.566 ٪) في الالواح المصنعة بتانين الصنوبر وتانين البلوط على التوالي عند نسبة التانين 25٪ ودرجة حرارة 170 م ومدة كبس 15 دقيقة ، وبلغت اقل نسبة للانتفاخ بالسمك (18.204 ٪) في الالواح المصنعة بتانين الصنوبر بنسبة 50٪ ودرجة حرارة 190 م ومدة كبس 8 دقائق وبلغت (18.904 ٪) في الالواح المصنعة بتانين البلوط بنسبة 25٪ ودرجة حرارة 170 م ومدة كبس 15 دقيقة ، وبلغت اقل نسبة للتمدد الطولي (0.05 ٪) في الالواح المصنعة بتانين البلوط بنسبة 50٪ ودرجة حرارة 190 م ومدة كبس 15 دقيقة و(0.14 ٪) في الالواح المصنعة بتانين الصنوبر بنسبة 25٪ ودرجة حرارة 170 م ومدة كبس نفسها .وبصورة عامة يمكن اجمال نتائج هذا العمل ، بامكانية استخدام المستخلصات المائية لقلف اشجار صنوبر زاويتوابلوط الاكل بعد سلسلة من خطوات التحوير الكيميائي لها كلاصق في صناعة الالواح الحبيبية المضغوطة الملائمة للاستخدامات الخارجية لمتانتهوامقاومتها للرطوبة. | Adhesives play an important role in the manufacture of wood - based products specially in particleboard mills. The resins manufactured are usually the range of amino and phenolic resins. For particleboards, only urea - formaldehyde and melamine urea - formaldehyde resins are being utilized.The use of tannin adhesives for manufacture of exterior grade weatherproof panel products has been gaining increasing industrial and technical acceptance during the last 50 years. All the formulations used industrially up to now have been based on the use of resorcinolic - type polyflavonoid tannins such as wattle (mimosa extract of commerce) and quebracho. These products have been progressively displacing synthetic adhesives in countries where these tannins are produced due to their lower cost and excellent performance. In this study tannin extracts from the bark of two main species grown in the northern part of Iraq ( Pinus brutia and Quercus aegilops ) were used as adhesives for particleboards production . The study involved two parts, the first part delt with the processes of extraction in laboratory scale and commercially. In laboratory, tannins were extracted with three degrees of purity by using three different sequences. In summary the two Iraqi trees examined appeared to have barks that are suitable for the production of tannin extracts in sufficient yield, with a high tannin content ( 15.3 ; 12.65 %) in Pinus brutia and Quercus aegilops respectively , and more than adequate reactivity to commercial and technically viable tannin - adhesives for wood products.The nature and the compounds included in these tannins were confirmed by TLC technique the identified compounds isolated from Pinus brutia bark tannins were {( - ) catechin, ( - ) epicatechin, ( - ) gallocatechin, (+)afzelechin } and from Quercus aegilops bark tannins were {gallic acid , phloroglucinol , ellagic acid, ( - ) gallocatechin, ( - ) catechin, ( - ) epicatechin, ( - ) epiafzelechin, (+) afzelechin}. It appeared that, Pinus tannins were mainly consist of condensed type with some hydrolysable type compounds while in Quercus tannin compounds were mainly of hydrolysable type and some of condensed type as a complex mixture. In the second stage of this part, tannins extracted in al large scale with aqueous extraction by the digester, 0.25% of sodium sulphite and sodium bisulphite were added to the extracts in order to increase their stability untile use . Then the whole extract of each bark species concentrated to 50% solid content, the extracts were ready to be used for manufacturing of panels in the later section of this study.In the second part panels were manufactured at laboratory scale. Prior to panels manufacturing the concentrated extracts were methylated by 10% of Para formaldehyde as a hardener at extracts pH of 5.5. The gel time and pot life were determined experimentally for the two extracts.Because of the existence of non - tannins compounds, the T - F extracts were mixed with urea - formaldehyde (UF) in different percentages for fortifying the T - F polymer. 180 panels of laboratory scale particleboards were manufactured at two levels of tannin sources (Pinus brutia and Quercus aegilops) , five levels of mixing percentages of tannin : UF namely ( 100 : 0 ; 75 : 25 ; 50 : 50 ; 25 : 75 and 0 : 100 ), two levels of press temperature (170 ; 190 °C ) ,three levels of press time ( 8 ; 10 ; 15 ) , each treatment was replicated three times. The panels were manufactured under pressure of 1250 psi , 10 % resin content ( based on oven dry weight of the chips and 50% solid content of extracts ) were used to get a target density of 0.6 gm/cm3 at panel thickness 18 mm . The physical and mechanical properties of produced panels were tested according to ASTM standard 2559 (1961). The results showed that Pinus brutia tannins get better mechanical properties (MOR, MOE and IB) of panels than Quercus aegilops and, it appeared that there is a possibility of fortifying tannin adhesives and getting better properties by using urea - formaldehyde with 25 - 50 % Pinus brutia tannins and 25 % with Quercus aegilops tannins. Press temperature (190° C) also improved the mechanical properties of panels, at 10 minutes pressing time. The highest values of MOR were (160. 45, 159.75 kg \ cm2), of MOE were (11339.7, 10883.7 kg \ cm2) and of IB were (7.33, 6.06 kg \ cm2), for Pinus brutia tannins and Quercus aegilops tannins respectively obtained at 190° C and 10 minutes pressing time. The panels were close in their mechanical properties to the values mentioned in ASTM 2559. With regard to the physical properties of panels (water absorption, thickness swelling and linear expansion percentage) revealed tannins behaviour, formaldehyde and wax content for pine and esters for oak as hydrophobic materials. Both types were equal in improving the physical properties of the panels. It is noticed that fortifying tannin adhesives by urea formaldehyde at 25 - 75 % of Pinus brutia tannins and 25 - 50 % of Quercus aegilops tannins a better results can be obtained. Press temperature reduced moisture content and increased panel resistance to water absorption at 15 minutes pressing. The lowest water absorption % were (59.971 and 60.566%) in panels produced from Pinus brutia tannins and Quercus aegilops tannins respectively both at 25 % tannin, 170° C and 15 minutes pressing. The lowest thickness swelling was 18.204 % in panels with Pinus brutia tannins at 50 %, 190° C and 8 minutes pressing time. As for Quercus aegilops tannins, the lowest thickness swelling was (18.904 %) in panels at 25 %, 170° C and 15 minutes pressing time. The lowest linear expansion was (0.05 %) in panels with Pinus brutia tannins at 50 %, 190° C and 15 minutes pressing time, and 0.14 % for panels made from Quercus aegilops tannins at 25 %, 170 ° C and 15 minutes pressing time. The results of this work can be summarized that there is a possibility of using aqueous extract from the bark of Pinus brutia trees and Quercus aegilops trees after chemical modification as a binder in particleboard production. The results also showed that there is an ability to substitute 25 - 50 % of synthetic adhesives by Pinus brutia tannins and by 25 % of Quercus aegilops tannins, at 190 °C press temperature and press time 10min. A good hydrophobicity appeared in the panels, because of the existence of tannins, formaldehyde, and wax content
