( Bhooth - 158 , IPA - 99 , Bhooth - 22, Abu - Graib - 3 and Fateh ) for the four levels of N, P and K zero, (60 kg N + 13.8 kg P + 25 kg K hˉ1) , (120 kg N + 27.6 kg P +50 kg K hˉ1) and (180 kg N + 41.4 kg P + 75 kg K hˉ1) . The experiment included 20 treatment came from the combination between wheat cultivars and fertilizer levels . Split - plot design was used in rendomized block design with three replicates , the level of fertilizer were the main plots , where as wheat cultivars were the Sub - plots . Resulte showed the five cultivars are different in it's characteristics as the Bhooth - 158 was superior in number of days to 50% of spiking to maturation (53.75 days ) , flag leaf area ( 48.87 cm2 ), weight of 1000 seeds ( 40.32 gm ) , biological yield ( 21.39 ton .hˉ¹ ) . IPA - 99 was superior in spike length ( 12.56 cm ) , number of seeds per spike( 985.08 ) . Bhooth - 22 was superior in characteristics of seed yield ( 7.91 ton.hˉ¹ ) , harvesting index ( 41.10 % ) and protein yield ( 902.09 Kg hˉ ¹) . Abu - Graib cultivar was superior in plant height (90.62 cm ) ,number of tillers .mˉ 2 (958.10) ,number of spikes .mˉ 2(859.08) and spiking efficiency (89.75% 0 . Fateh cultivar gave the highest number of days from planting to 50% spiking ( 111.59 days) and protein content ( 12.13% ) . Results showed a variance among fertilizer level where F₃ level (180 Kg N + 41.4 Kg P + 75 Kg K hˉ ¹) caused highest number of days from planting to 50% spiking (104.07 days) , number of days from 50% to maturation ( 48.27 ) , plant height (89.98 cm ) flag leaf area (46.50 cm2 ) , spike length ( 12.36 cm ) number of seeds per spike ( 76.78 seed . spike ˉ ¹) . The F₂ level ( 120 kg N + 27.6 Kg P + 50 Kg K hˉ ¹) was superior in number of tillers (828.00 ) , seed yield ( 7.69 ton .hˉ ¹), biological yield ( 20.97 ton .hˉ ¹) , protein (11.78% ) and protein yield (0.906 ton .hˉ ¹) . The F₁ level ( 60Kg N + 13.8 Kg P + 25Kg K hˉ ¹) was superior in number of spikes per. m2 spike .m(609.80 spike .mˉ 2 ) and protein percent(11.72% ) which not significantly different from level F₂ . There were no significant effect of fertilizer levels on spiking efficiency , weight of 1000 seeds and harvesting index . There were an interaction between cultivars and fertilizer level in all characteristics except the weight of 1000 seeds . Bhooth 22 × F₂ level ( 120 kg N + 27.6 Kg P + 50 Kg K hˉ ¹) produced highest seed yields ( 8.55 ton . hˉ¹ ) and protein yield ( 1.01 ton .hˉ¹ ) which was not significantly different from the interaction between Fateh cultivar and 400 kg .hˉ¹ fertilizer which produced protein ( 0.993 ton .hˉ¹ ) . Fateh cultivar fertilized by 400 kg. hˉ¹ NPK produced highest protein percent which was 12.97 % . There was a positive correlation among seed yield and plant height , flag leaf area , number of tillers , spike length , harvesting index and protein yield . A negative correlation was found between seed yield and spiking efficiency . The best economical profit came from the use of F₂ level ( 120 kg N + 27.6 Kg P + 50 Kg K hˉ ¹) which produce ( 7.76) Iraqi dinar for each one dinar used for fertilizer used in north Basrah . The interaction between Bhooth 22 cultivar and level F₂ produce highest product ( 14.70 ) dinars to each one dinar invested in the use of NPK fertilizer that supported by government

دراسة التنوع الوراثي للجاموس العراقي باستخدام تقنيتي RAPD وSTR Study of Genetic Diversity of Iraqi Buffalo by RAPD and STR

المستخلص: The current study was conducted in the laboratory of Dr. TalibAhmed Jaayide Molecular Genetics / Faculty of Agriculture /University of Basrah. After collecting blood samples from the Iraqibuffalo in the provinces of Basrah (30 samples), Dhi Qar, Maysanand Najaf (25 samples each), bringing the total samples to 105samples. The study aimed to study the genetic diversity of the Iraqibuffalo through the use of tow techniques, first technique was, thePCR - RAPD technique and the second microsatellite technique(PCR - STR). After extracting the DNA samples, seven primers ofPCR - RAPD technique were used, included C01, C04, C06, C07,C09, C11 and C12. Primers of PCR - STR technique wereILSTS005, ILSTS029 and ILSTS072. After analyzing the results ofthe three technologies it can be summarized as follows : 1 - All primers of PCR - RAPD showed genetic polymorphisms,with the presence of many bands except the primer C11which was notamplified in all samples.2 - The size of primer C07 was 1969 bp, which was the biggestprimer size, however, the smallest primer size was C01(1606 bp).3 - Number of bands showed by PCR - RAPD primers were 28,42, 56, 53, 57 and 64 bands of C01, C04, C06, C07, C09,C12 primers respectively.4 - Primer C09 revealed the highest number of polymorphicbands in Basra and Dhi - Qar provinces (47 and 46 bandsrespectively). However, the primer C12 gave highest numberof polymorphic bands in Maysan (47 bands). The primer C01showed lowest number of polymorphic bands in all studiedprovinces (14 bands in Basra and Dhi - Qar provinces, 12bands in Maysan and 13 bands in Najaf province.5 - Shared bands between Basra and Dhi - Qar, Basra andMaysan, Basra and Najaf, Dhi - Qar and Maysan, Dhi - Qar andNajaf and Maysan and Najaf were 177, 151, 162, 146 and152 bands respectively. The high number of shared bandsreflected high genetic similarly among provinces.6 - Maysan province showed highest special bands of primerC07 (8 bands) followed by Dhi - Qar province (5 bands) whichis considered as fingerprint for these provinces even they showed very low frequencies.7 - Primer C04 revealed lowest genetic diversity measured by Shannon index in all studied areas (28.82 - 35.58%), however, all other primers showed higher genetic diversity (47.57 - 55.70%).8 - Similarity among provinces was higher than 70% to 95% for all PCR - RAPD primers, which indicates that all subpopulations of buffalo belong to one breed.9 - Primers C07 and C12 highlighted highest percent of mean gene diversity to population diversity (GST) with a value of 22.69 and 21.46 respectively.10 - All STR markers (ILSTS005, ILSTS029 and ILSTS072) have been amplified in all buffalo samples of all studied areas. Observed allele numbers were 20, 22 and 21 alleles for markers respectively with a total of 63 alleles. The marker ILSTS005 gave highest number of observed alleles in Dhi - Qar (21), Najaf (20) and Maysan (17). Whereas, the marker ILSTS029 showed less number of observed alleles at Maysan province (9 alleles). 11 - Allele frequencies ranged from 0.02 to 0.32 for all markers and provinces.12 - Shared alleles between Basra andDhi - Qar, Basra and Maysan, Basra and Najaf, Dhi - Qar and Maysan, Dhi - Qar andNajaf, Maysan and Najaf were 25, 27, 30, 22, 33 and 33alleles.13 - Special allele mean frequency of studied population was 0.048. While gene flow after adjusted for sample size of each province was 2.25 alleles. Range of missing allele frequency for all studied areas was 0.000 - 0.099.14 - Range of heterozygosity percent was 80 - 100%, whereas homozygosity% was 0 - 20%.15 - All Fis values of studied markers in all provinces were significant except the marker STR072 in Dhi - Qar province which was nonsignificant. This result reflected the absence of inbreeding in all areas and there was no significant deficiency in genetic variation.16 - Linkage disequilibrium test showed that tested markers are not located on one chromosome.17 - The study thus highlights the usefulness of heterologous PCR - RAPD and microsatellite markers to assess the genetic variability in buffalo. Also various diversity indices suggest sufficient genetic variability within Iraqi buffalo that can be utilized as initial guidelines for future breeding strategies and conservation.

المستخلص: Lactobacillus bacteria was Isolated from different food samples included (bananas, tomatoes, apples, mandarin orange, cheese, buffalo milk, local yogurt and imported yogurt) and from infant feaces . 65 isolates were obtained out of 64 food samples, and 11 samples of infant feaces belong to Lactobacillus spp. and identified depending on selective medium MRS agar as well as phenotypic tests, microscopic tests and biochemical examinations including catalase test, production of Co2 from glucose, gelatin liquefaction, ammonia reduction from arginine, nitrate reduction to nitrite, growth examination in different temperatures, indole test, salinity tolerance test, motility test and carbohydrate fermentation test. As well as, confirmed test was done by using PCR technique. Purification and identification conducted and showed it contain (20) isolates of Lactobacillus acidophilus, (23) isolates of Lactobacillus plantarum, (6) isolate of Lactobacillus casei, (12) isolates of Lactobacillus bulgaricus, (3) isolates of bacteria Lactobacillus johnsonii and one isolates of Lactobacillus helveticus. The identified isolates of Lactic acid bacteria were tested on the production of polysaccharide and the optimal conditions for the production by using the modified medium by adding lactose to the medium and vaccine volume was 0.1% and the temperature of incubating was 37c° for (24 - 48) hrs and pH was (6.2 - 6.5) and centrifuged (11000) rpm. Detction of polysaccharide for all obtained bacteria was done . Results showed that the bast of amount production of polysaccharide to(Lactobacillus plantarum )which isolate from imported yoghurt (yR5) because it got the best amount of polysaccharide production which was (850.35) m / ml.SummaryThe presence of polysaccharide was detected by using thin - layer chromatography technique TLC to make sure from the presence of sugar molecules by using sulfuric acid and then the produced polysaccharide was detected by using High Performance Liquid Chromatography Technology HPLC with the existence of standard saccharides for the purpose of detection and comparison.Inhibition activity of both crude bacteria cells and produced polysaccharide were studied against gram positive and negative bacteria which included Staphylococcus aureus, Escherichia coli, Streptococcus spp., Pseudomonandas aeruginosa and E. coli O157 : H7 as well as the inhibitory activity against fungi was determined for each crude bacteria cells and produced polysaccharide especially against Penicillium spp. and Asprgills niger Result showed that in habithion effect was apparel towel all microorganism however no effect E. coli O157 : H7.Anti - oxidant activity of crude bacterial isolates were tested and the best anti - oxidant activity (Lactobacillus acidophilus (was the isolate which isolated from bananas source (B4) Mar 51.01% reached while less effective was the isolation (Lactobacillus bulgaricus) isolated from the local yogurt source (yL2) if it reaches 14.04% and the highest antioxidant activity of polysaccharide was from the isolate(Lactobacillus bulgaricus) which isolated from the local yogurt source (yL6) , amounting to 67.51% while it was less effective than isolation (Lactobacillus acidophilus ) isolated from the local chess source (Cha2) as it was 1.29% compared with the industrial anti - oxidation BHT and the natural anti - oxidation α - tocopherol in concentration (0.05 g / ml), results showed that the anti - oxidant activity by using the industrial anti - oxidant BHT reached to 82.70%, while the highest inhibitory activity of bacteriaSummaryanti - oxidant compounds 51.01% and for polysaccharide the highest percentage of inhibition was 67.51%, the bacteria anti - oxidant compounds and polysaccharide activity were close, while the activity of the natural anti - oxidants α - tocopherol was 73.96%.The results of sensitivity toward 10 antibiotics showed that all isolates of lactobacillus spp. Were sensitive to clindamycin. While only 16% of isolates were sensitive to nalidaxic acid.The cytotoxicity effect of the Heat killed (HK) cells and polysaccharide extract (EPS) of local isolates of Lactobacillus spp. on three of the cancer cells lines, human cervix uteri epitheloid carcinoma (Hela), muscular cancer cells line (RD) and rat embryogenic fibroblast (REF) as normal cell line , were studied . In this study, six concentrations of both polysaccharide extract and the (HK) cells which were (93.5, 187.5 , 375, 750,1500, 3000) mcg/ml. The results showed that all types of dead cells of lactic acid bacteria and polysaccharide product which clear effect on tumor cells differed depending on the degree of influence, polysaccharide extract of Lactobacillus johnsonii showed highest percentage of inhibition and the highest percentage of inhibition for (Hela) line was (93.64%) at exposure time of 72 hours. while the highest percentage of inhibition recorded for Lactobacillus acidophilus in (RD) line cells was (90.63%) after 72 hours. For the (HK) cells, the highest percentage of inhibition for Lactobacillus casei was 89.77 after 48 hours. While it was no effect of polysaccharide and HK on (Rat Embroy Fibroblast) ofter exposure time 72h.

مقارنة عزلات مختلفة من الفطر Rhizoctonia solani Kühn باستخدام تقنيات الوراثة الجزيئية وبعض المعايير المظهرية والفسلجية

المستخلص: This study had been carried out at Plant Protection Department and Genetic Engineering Labs of Agricultural College / Basrah University, while pots experiments were carried out at fields of Agricultural College / Basrah University. The present study included a comparison experiments of different Rhizoctonia solani isolates depending on molecular genetic techniques alongside with morphological and physiological parameters, host range and anastomosis groups identification.Thirty two different isolates of R. solani have been isolated from several host plants from several plant families throughout different geographical areas at Basra governorate. Result of pathogenicity test revealed that the majority of R. solani isolates caused a significant reduction in the germination percent of cabbage seeds, the isolates of Rs5, Rs16 and Rs19 were found to be more pathogenic and led to complete inhibition of germination, hence, the other isolates varied in their effect on seed germination percent and reported the range of 3.3 - 66.7 %, while, the isolate of BRs15 (binucleate isolate) did not show any significant effect on seeds germination compared to control (untreated) treatment (100%). According to pathogenicity test results, the most pathogenic isolates (Rs2, Rs5, R9, Rs16, Rs27 and Rs29) were selected for more followed experiments.Morphological analyses of R. solani isolates elucidated a profound difference among these isolates, the colony color was dark brown with the Rs9 isolate, light brown at the Rs16, while it was cream at the Rs2, Rs5, and Rs27, a white color with light brownish color was observed with the isolates of Rs29. The growth patterns at the medium supplemented with Potassium Chlorat showed that the isolates of Rs5, Rs9, Rs27 and Rs29 were sensitive to chlorate, while, the isolates of Rs2 and Rs16 were resistant to Chlorate. Regaling the effect of temperature on the growth of R. solani, it was found that the optimal growth temperature was at 25 °c for all examined isolates, while no growth was observed for all isolates at the temperature of 10 and 40 °c. The best pH values for growth supporting were 6 and 7 for all examined isolates.Anastomosis group analysis revealed the occurrence of anastomosis among the isolates of Rs5, Rs16, Rs27 and Rs29 with the standard isolate AG2, this confirms that these isolates belong to the group AG2, while the anastomosis between the two isolates Rs2 and Rs9 with standard isolate AG2 did not happen, therefore these isolates belong to a different group. Microscopic observation revealed theBoccurrence of more than two nuclei in each cell of examined isolates the average of nuclei number was 4 - 8 nucleus / fungal cell, while the number of binucleate isolate BRs15 exhibition two nuclei / fungal cell.The DNA extraction experiments for R. solani isolates (Rs2, Rs5, Rs9, Rs16, Rs27, Rs27, Rs30 and AG2) revealed the efficiency of CTAB procedure to get a high DNA yield and that it’s a good quality, as indicated results of measuring the concentration of DNA isolates it was good quantity amount (197.9 - 560.4 ng / μl) was obtained by following this procedure. The random amplified polymorphic DNA (RAPD) results showed that all DNA of examined R. solani isolates were amplified by employing different RAPD primers, also each genetic primer succeeded in differentiation among isolates, as showed the polymorphic bands and monomorphic bands.The results of restriction fragment length polymorphism technique (RFLP) using RS1 and RS4 primers showed that the bands size for R. solani isolates obtained between 500 - 522 bp, restriction technique results using enzymes AvaII, HincII, MseI and MunI showed that Rs2 isolate belong to the group AG1 - IB, while Rs5, Rs16, Rs27, Rs29 and the standard isolate (AG2) belong to the group AG2 - 2, while Rs9 isolate belongs to group AG11 so Rs30 isolate belongs to group AG3 - PT.Result of host range of R. solani isolates showed a significant differences in the host preference, the isolates of Rs2 was able to infect all plant hosts except okra plant, while Rs5, Rs16, Rs27 and Rs29 were able to induce the infection on marshmallow, okra, cowpea, cotton and eggplant, no infections were reported on the host of melon and wheat plants, regarding R. solani isolate Rs9 an infection was observed on marshmallow, wheat and cotton, while no infection was noticed on melon, okra, cowpea and eggplant.Results of binucleate R. solani isolates role in protection of cotton plant from the infection with R. solani, revealed their protective role, the pathogenic effect of R. solani was significantly reduced, the germination percents were increased with BRs15 treatment reached 83.3, 86.7, 93.3, 83.3 and 90% at the treatments of Rs2, Rs5, Rs9, Rs16 and Rs27 respectively, without any significant difference with control treatment (93.3%). The highest germination percent was observed at BRs15 treatment with Rs29 and reported the percent of 96.7 %. Similar results were observed with damping - off percent of cotton plant, which proved the significant efficiency of binucleate isolate in their protection against all examined R. solani pathogenic isolates.

مسح وتشخيص بعض الملقحات الحشرية ومصادر حبوب اللقاح في محافظة ميسان Survey and Identification Some Pollinators and Pollen Resources in Missan Province

المستخلص: survey and identification of the most important pollinators were conducted in three locations in Missan province (Amarah, Maymonnh , Almajar alkabir) , for the purpose to survey and identify the most important pollinators in the province,In view of the diversity of plants and insects pollinators the study select three plants , ber tree Ziziphus spina - christi and two crops are alfalfa Medicago sativa and Egyptian clover Trifolium alexenderianum to confine the pollinating insects. Honey bee Apis mellifera be one of the most important pollinator . So pollen sources in the sediment of honey and propolis is studied to identify botanical origin that visited by insects to keep them and provide fingerprint about plant diversity in the province.The study showed the following : 1. there are many insects visiting flowers of ber , alfalfa and clover were some of them are classified to the species level, while others were classified to the generic level such as wild bees Andrena sp. , Megachle sp., Tetralonia sp.And some species belong to family syrphidae such as Eristalis sp. , Syrtta sp. and Syrphus sp..2. Honey bee Apis mellifera is the most common and attracting to the two experiment crops flowers . where on average of 0.978 insects per 3m² during five minutes in alfalfa and 1.2 insects in clover were recorded. the second important is the wild bee Andrena sp. with an average of 0.662 insects in alfalfa and 0.8 in clover. 3. Honey bee were holding maximum quantity of pollen from alfalfa and clover . The average load was 67874 Pollen Grains (PG) was recorded . This quantity may be greater when it's estimated in the bee when they returns to hive .Wild bee Andrena sp. loud of pollen grain counted 54233 PG and ,IIthe wild bee long horn Tetralonia sp. carry about 51664 PG , while the leaf cutter wild bee Megachile sp. and white - banded digger Amegilla quadrifasciata carry 44256 and 38154 PG respectively , The least loud was carried by syrphid fly Eristalis aeneus was 27657 PG in it's gut .4. Honey bee Apis mellifera was the most insect spending time of foraging pollen on clover in average 9.76 second and 8.85 second on clover and alfalfa flowers respectively in the daylight , the next were the miner bee Andrena sp. spending 5.53 sec and 4.32 sec on clover flowers and alfalfa respectively . The white - banded digger wild bee A. quadrifasciata and the leaf cutter wild bee Megachile sp. have not seen visiting clover while they visit alfalfa flowers .5. pollen spectrum in spring and autumn honey sediment was studied , wich showed an important and new sources the tamarisk Tamarix brachystachys that is record the first time as a predominant pollen source , this source rated over than 45% in three sample of spring honey while as known between researchers and bee keepers that spring honey called a Eucalyptus or clover honey. Some weed were also important as pollen sourcessuch as Capparis spinosa , Sonchus oleraceus in addition to Prosopis juliflora and some species of the Families Cruciferae , Compositae and Umbelliferae.6. the light microscope showed that The most important resource of propolis Eucalyptus camaldulensis , Tamarix spp. and Prosopis juliflora

المستخلص: The current study was carried out during the period from December 2015 and June 2016 to assess the chemical composition, fatty and amino acids and the total bacterial count of the muscular tissue from the common carp Cyprinus carpio L. in Basrah city which were cached from Shatt Al - Arab river at Abul - Khasib, obtained from earthen ponds at the University of Basrah, fish cages in Shatt Al - Arab river at Al - Hartha district and those imported from Iran Republic which were available in the domestic markets of Basrah city.The results of the study were statistically analyzed using CRD design applying SPSS statistical package ver. 17 on 50 fish from each source with 3 replicates per sample and the studied factors were tested using RLSD test at 0.05 probability level.The results of the statistical analysis indicated no significant differences (p>0.05) in moisture content between Shatt Al - Arab samples, imported samples, iced pond fish and iced cage fish. No significant differences (p>0.05) were detected also between fish from ponds and cages. Significant differences (p<0.05) were detected between fresh fish from ponds and cages with fresh and iced fish from Shatt Al - Arab or imported fish. The highest moisture content of fresh fish was 78.2% in Shatt Al - Arab samples while the lowest 70.8% was in fresh cage fish. The highest moisture content in iced fish 79.4% was in imported samples while the lowest 74.1% was in cage fish. As for ash content, the statistical analysis revealed significant differences (p<0.05) between imported fish and other fish samples. Significant differences (p<0.05) were observed also between fresh pond fish and other samples.However, no more significant differences (p>0.05) were detected between other fish samples. The highest ash content in fresh fish 2.29% was in pond fish and the lowest 0.98% in imported fish. Similarly, the highest ash content in iced samples 1.45% was in pond fish and the lowest 0.87% in imported samples. The statistical analysis of fat contents demonstrated significant differences (p<0.05) between Shatt Al - Arab fresh and iced samples and other samples. Fat content in pond fish was in line with those in iced cage and iced imported fish but significantly (p<0.05) differ from those in fresh pond and imported fish while no such differences were shown between pond and imported fish. The highest fat content in fresh fish 11.9% was in imported fish and the lowest 3.43% in Shatt Al - Arab fish. Similarly, the highest fat content of iced fish 9.99% was in imported fish and the lowest 3.17% in Shatt Al - Arab fish. The statistical analysis showed that protein contents in fresh fish from Shatt Al - Arab, ponds and cages were significantly (p<0.05) higher than those in imported fish while protein contents in fresh and iced imported fish were significantly (p<0.05) lower than it in other fish. The highest protein content in fresh fish 18.71% was in pond fish and the lowest 10.05% in imported fish. Similarly, the highest protein content in iced fish 16.96% was in pond fish and the lowest 9.98% in imported fish. The statistical analysis showed that the caloric values of fresh and iced fish from Shatt Al - Arab were significantly (p<0.05) lower than other fish except for iced pond and imported fish. Additionally, no significant differences (p>0.05) were observed in caloric values between pond, iced cage and imported fish while pond and Shatt Al - Arab fishes only showed significant differences (p<0.05) in comparison with other samples. The highest caloric value for fresh fish 165.62 Kcal/100 g in cage fish and the lowest 98.5 Kcal/100 g in Shatt Al - Arab fish. On the other hand, the highest caloric value for iced fish 148.4 Kcal/100 g was in cage fish and the lowest 93.9 Kcal/100 g in Shatt Al - Arab fish.The fatty acids was assessed in the laboratories of The College of Agriculture, University of Basrah by using GC - MS QP210 Ultra , SHIMADZU, JAPAN equipped with capillary column DB - MS 5 with static phase (5% phenyl, 95% methyl polysiloxane) and ultra - high purity Helium 99.9%. The fatty acid analysis for the muscular tissue of fish indicated high levels of oleic ،palmitic ،stearic ،stearic ،docosahexaenoic acid in comparison with lower levels of myristoleic ،eicosadienoic ،dihomo - gamma - linolenic and pentadecyclic acids. The statistical analysis revealed no significant differences between both fresh and iced samples from the different fish sources. However, significant differences (p<0.05) were detected between imported fish and fresh and iced fish from ponds and cages. Additionally, no significant differences (p>0.05) were observed between fresh and iced imported samples with both fresh and iced pond fish while fresh and iced cage fish differed significantly (p<0.05) from fresh pond samples.Amino acids were assessed by using HPLC system with ion exchange and Ninhydrin post column derivation in Shimadzu Spd - 6 Av uv - Visible detector. The analysis of amino acids in fish muscular tissue demonstrated high levels of Aspartic ،Serine ،Glutamic،Alanine and Glycine and low levels of Cystine ،Tryptophan ،Isoleucine ،Methionine،Histidine ،Threonine and Tyrosine. The statistical analysis showed no significant differences between fresh and iced Shatt Al - Arab samples with fresh and iced imported fish. No significant differences (p>0.05) were observed also between fresh and iced pond fish with fresh and iced cage fish. On the other hand, significant differences (p<0.05) were found between fresh and iced Shatt Al - Arab fish with fresh and iced imported samples. Additionally, another significant differences were detected between fresh and iced pond fish with fresh and cage fish.As for the total bacterial count, the statistical analysis revealed significant differences (p<0.05) between all fresh and iced fish samples. The highest level in fresh fish 7.6 x 103 cfu/g was observed in Shatt Al - Arab fish while the lowest level 2.0 x 103 cfu/g in imported fish. In comparison, the highest level in iced fish 7.44 x 107 cfu/g was also in Shatt Al - Arab fish but the lowest level 5.72 x 107 cfu/g in cage fish.

التنوع السمكي وبعض الخصائص الحياتية في الجزء الشمالي لشط العرب وبعض مقترباته Fish biodiversity and some biological characteristics in the Northern part of Shatt Al - Arab River and some of its reaches

المستخلص: The aimed of the present study to find out the nature of the qualitative compositionand some biological aspects in the North part of Shatt Al - Arab River and some of its reaches after emergence of many changes in the region and habitats segmenting by Dam construction on Euphrates River in the area between Chibyish and Mudina town and establishment of Qlat - Salih Regulator, reduction of water discharge to minimum limits, entry of alien species on an ongoing basis, so it is necessary to conduct a study to find out the nature of the diversity of fish in the region, and it has shown that the composition of community differs from previous studies revealed that introduced alien small size species and some of uneconomic species were dominate. The samples were caught monthly from the river from December 2013 to May 2015 North of Basrah Province. Several fishing tools were used to collect fishes seine, fixed, draft, cast net and electrofishing. Three stations were selected; the station 1 was in the North of Qurna town about five kilometers North the point which the Tigris and Euphrates River confluence, station 2 at the place of Seweeb River is meeting the Shatt Al - Arab Rive and station 3 at the point that Al - Shafii River which meet Shatt Al - Arab river. Some environmental parameters were measured, namely air temperature ranged from 15ºC in December 2014 in station 3 to 43ºC in the August 2014 at station 2 and 3, while the water temperature from 11ºC in January 2015 for station 1 to 36 ºC in July at station 2. Light penetration revealed 33 cm in April and May 2014 and 132 cm in January 2015 for station 3. Current speed ranged between 0.03 m/s in January 2015 in station 3 and 0.29 m/s in October 2014 for station 1. Salinity ranged from 0.66 g/L in January 2014 for station 1 to 1.46 g/L in February and March 2015 in station 1 and October 2014 for station 2. The pH values tend toward the alkaline, the lowest 7.30 in May 2014 for station 2 and 8.90 measured in February 2014 in station 1. Monthly discharges, average incoming from the Tigris River recorded 35.20 ± 8.47 m3/s in November 2014 to 73.85 ± 17.55 m3/s on February 2014. Lower values of reactive nitrate were recorded 0.69 μ g at. N/L in March 2015 at station 3 and highest 24.32 μ g at. N/L in May for station 2, however the values of reactive phosphate recorded, the lowest 0.0037 μ g at. N/L in March 2015 at station 2, the highest was 0.589 μ g at. N/L in November 2014 for station 1. A total of 29405 individuals was collected during the study period represented 916521g included 33 species eight of them were marine species contain 29 genera belong to 14 families of Osteichthyes, Cyprinids family occupied first degree in the number of species (13) and genera (12), the numerical relative abundance of marine species in the study area was 3.38% and the relative abundance gravimetric was 8.45%. A significant positive correlation was found between number of species and water temperature (r=0. 506). Liza abu, Carassius auratus and Coptodon zillii were the most total numerical relative abundance 30.89, 29.30 and 15.64 % respectively, C. auratus, S. triostegus and C. zillii were the most total weight relative abundance and composing 27.58, 14.27 and 11.64% respectively in the study area. Discharges rates flowing from the Tigris River revealed negative effect with the number of species and the insignificant negative correlation was recorded (r= - 0.109) with discharge monthly rates, and fluctuation relationship was noticed between discharges and ecological indices. However, native species included 15 seasonal species 4 and 14 for rare species. Diversity index (H) ranged between 0.91 in January 2015 at station 3 to 2.05 in March 2015 for station 2, richness index (D) 0.83 in February 2014 at station 3 and 2.79 in March 2015 at station 1, evenness index (J) recorded 0.38 in January 2015 and the highest 0.78 in September 2014 for station 1. The percentage of similarity among stations by Jaccard similarity index (Ss%) showed variation uneven during study months. Cluster analysis of species similarity pointed to clumping in groups controlled by temperature. The Multivariate analysis was (CCA) adopted to clarify the impact of a biotic factors on the distribution of species. Total catches were ranged between 16380 g in December 2013 to 80309g in December 2014. The total average catch per unit of effort was 24.953 kg/hr for seine nets ranged from 0.928 kg/hr in December 2014 at station 2 to 30.271 Kg/hr during January 2015 for station 3. The number of fishing boats in the study area 143 their length between 5 - 7m most of them without an engine. The impact of alien species direct effects during the destruction of nests and reproductive ground, especially eggs which lie on a plant for native species and hybridization between alien and native species, and indirect effects of competition on food, ecological space, environment destruction and aggressive behavior. The length groups of all fish species were recorded, the lowest values were for Alburnus mossulensis, Acanthobrama marmid, Hemiculter leucisculus and Garra rufa, they were 7.3 - 18, 6.3 - 17, 7 - 17 and 7.2 - 17.8 cm respectively, whereas the highest were for Silurus triostegus, Leuciscus vorax and Mastacembelus mastacembelus, they were 10.8 - 72.4, 9.5 - 57.3 and 14 - 55 cm respectively. Faben method used for estimating growth parameters (L∞,K) by applying FiSAT program for C. auratus, Carasobarbus luteus and L. abu, the values of L∞ for three species 38.97, 35.69 and 22.19 cm respectively, and for K 0.29 to the C. auratus and C. luteus and 0.41 for L. abu, the results revealed five years age for C. auratus and C. luteus whereas four years age for L. abu. The present study showed high values of diet overlap between L. abu and Cheon subviridis 09% also high values 90% Oreochromis aureus and Oreochromis niloticus S. triostegus and L. vorax 89%, but it did not reach the competition limit, also high diet overlap 86% and competition was found between C. auratus and C. luteus Absolute fecundity for C. auratus females ranged from 1303 for 8.8 cm total length and 10g weight to51245 egg for 30.1 cm total length and 557g weight, and for C. luteus from 2098 for 13.1 cm total length to 14147 egg for 20.9 cm total length and 131g weight, while in L. abu from 6247 for 9.7 cm total length and 11g weight to 41219 egg for 17.5 cm total length and 63g weight.

The present study revealed that the best weight for juvenile in laboratory which were feeding on diet contain 42% protein with high survival rates between 90 - 95%, this reverse on the chemical composition of prawn body after the experiments. Showed result behaviour that this prawn preferred to feeing hold on the ponds columns, it reach a best weight by using flake feed (Aquafin), with survival rate 95% during the experimental period. The salinity acclimation and oxygen consumption showed that LC50 for juvenile was 15.5 psu after 96 hours, with high survival rate in tow salinities 0.9 and 5.0 psu. A gradual increasing in oxygen consumption with increasing temperature and salinity clearly proved in this experiment. Sexual ratio was recorded to be 1 : 3.8 for males : females respectively. The number of eggs were collected from Al - Masshab Outlet between 3,600 - 10,200 egg for number of females, while the ranged of all hatching larvae were 1,632 ± 861 zoae. The range of ratio of larvae to the ratio of body weight was 225 ± 110 g from body weight of prawn, and the present study showed that there is a correlation between female weight with both egg weight and number of hatching larvae, by using different nursing systems of newly hatched larvae for 12 to 22 day, and the larvae reached weight to 3 mg., while higher range of survival larvae were 63.75% in muddy pond, in others systems were 27.50 - 47.50 %.The final weight range were reached 813 and 978 (mg) for hatched juveniles that were reared in floating and emerged cages respectively, while the naturally reared Juvenile have weight range between 805, 950 (mg) for nature floating and emerged cages during 28 day, with a survival rate between 86 - 93%, and weight range of juvenile reared in closed system from 938 to 4,010 (mg) during 90 day, with survival rates 86 - 92 (%). High levels of survival rate recorded to be 78.13% for larvae and juvenile of prawn cultured earth in ground pond during 42 day, comparison with 47.50 - 58.13% in others system. The best weight for larvae that feeder on protein diet (46%) for six weeks in ground pond reached to 697 mg while the lowest weight in nursing system reached to 312 mg. The age which zoea needs Metamorphosis zoae between 12 - 22 days to reach post - larvae, were 23 - 44 day for Metamorphosis post - larvae to Juvenile, and this needs between 45 - 129 day for reached to sub - adult with in 130 - 179 day. After 180 day more prawn reached to adult stage.The hatchery production of zoea larvae was fluctuated between 53,504 - 190,000, it and between 32,355 - 99,560 post - larvae. The total production from earth pond (mud pond and fiberglass tank), the number of zoae larvae between 36,559 - 15,300,000 larvae, and between 21,248 - 11,954,400 post - larvae. While the total production in all culture systems were 12,600,188 - 15,760,462 zoea larvae, and between 9,753,349 - 12,197,630 post - larvae.The chemical composition for prepared diet the present study which used for nutritional diet experiment were 44.84 % protein, 51.27 % fat and 2.57 % ash.

معالجة مياه الصرف الصناعي لمعمل الاسمدة في المنطقة الجنوبية واعادة استعماها لري نبات الطماطة Lycopersicon esculentum Mill Industrial wastewater treatment of fertilizer factory south region and reuse for tomato irrigation( Lycopersicon esculentum Mill.)

المستخلص: The study was conducted to investigate the possibility of using the effluent originated from fertilizers factory/ south region, Basrah province for tomato irrigation. Effluent samples were collected from urea unite line, ammonia unite lion, and collection basin at nine periods during 3\9\2015 to 5\8\2016. Tap water was used as control water. Three types of filters were used to enhance the characteristics of water collected from the fertilizers factory which are Rice Husk Ash filter, sand filter and Rice Husk Ash + sand filter(75 : 25). chemical characteristics (EC, PH, Ca++, Mg++, Na+, K+, Cl - , SO4 - - , total hardness, NO3 - , NH4+, urea) were obtained before and after filtration then Removal efficiency (%) was calculated. Basin on above experiment, a pot culture experiment was conducted to study the effect of fertilizers industry effluents on chemical parameters of soil and its impact on growth parameters of the tomato plant. Each pot was prepared by filling loamy sand soil 10 kg collected from a farm nearby the factory. All the pots were fertilized by manure, phosphorus and potassium. Nitrogen fertilizer (urea) was applied an equivalent of 0, 50% and 100% of recommended level (300 kg N ha - 1). Tomato seedlings (hybride Newton F1) were transplanted in the pots. The pots were irrigated with above fertilizer industry effluents or tap water after the seedlings standing in the pots. After 90 days, soil and plant samples were collected to measure EC, pH, NO3 - in soil, NH4+ in soil, plant height, shoot dry weight, N concentration,number of flowers plant - 1 and number of fruits plant - 1.The results showed that there was a significant changes among sample periods in all water characteristics. The highest removal efficiency of urea, NH4+, NO3 - , cations and anions were recorded by using Rice Husk Ash filter, while the lowest efficiency were recorded by using sand filter. Data alsoBshowed that chemical parameters (EC, NH4+ and NO3 - ) of soil were differed by different filter used and follow the order : control (without filtration) < sand filter < Rice Husk Ash + sand filter < Rice Husk Ash filter. This result was reflected on plant growth parameters (plant high, shoot dry weight, N concentration ,number of flowers plant - 1 and number of fruits plant - 1) and follow the order : Rice Husk Ash + sand filter < Rice Husk Ash filter < sand filter < control. However soil pH was not affected at different filters used. Increasing the level of nitrogen significantly increased EC, NH4+ and NO3 - in soil and decreased soil PH resulted in increased plant parameters. Soil chemical parameters and plant growth parameters were differed by different source of fertilizers industry effluents and follow : ammonia line < urea line < collection basin < tap water. Data also revealed that tomato plant irrigated with water of ammonia line and filtered through Rice Husk Ash + sand filter showed best growth parameters as compared with other plants with higher shoot dry weight of 11.69 g plant - 1. The pot experiment suggested the possibility to using the water of ammonia line which filtered through Rice Husk Ash + sand filter with 50% of nitrogen recommended level to enhance tomato growth and it would save costs on fertilizer and reduction in pollution load of soil and water.
