Abstract:
The present experiment was carried out during two winter grawing seasons (2013 - 2014 and 2014 - 2015) in one of the dry land farms,khor AL - Zubiar Basrah with the objective of studying.The response of the Hybrid tomato (Lycoperiscon esculentum mill.) CV.Hitouf grown under plast poly ethyien to varins fertilizer treatment of organic fertilizer pow humus and inorganic fertilizer Agriculture sulphur .to study of the effect of the fertilizer treatment was on soil physical characteristics,vegetative growth characteristics,flowering and leaf chemical constituents wells quantitative and and quantitative yield ,and storability of behavior of the fruit at room temperature or cold storage .The experiment included nine treatments in afactorial mannes which were the combination of three levels of potassium humate (0 ,255 ,510 kg K.haˉˡ) and three levels of Agricultural sulfur (0 ,205 ,510 kg S. .haˉˡ) the experiment was performeal as factorial with completely randomized block design (CRBD)with three replicater Mean treatment value ware compared using least significant L.S.D at 0.05 level.The results may be sumuarized as follows : 1 - phsical and chemical soil characteristics .The addition of potassium humate at 255 and 510 kg K.hˉˡ caused significant increase in soil water content as compared with control treatment during the second growing season ,wheres the level of 255 kg k.ˉˡ caused asignificant decrease in soil pH as compared with control treatment as well as the level 510 kg K.haˉˡ humate during the first growing season caused asignificant decrease in soil pH,and Ec soil electrical conductivity for both growing seasons,and asignificant in lreane in soil moisture contant the yield growing season .For sulphur treatment ,it was fourd that the addition of Agricultural sulphur at 205 and410 kg S.haˉˡ caused asignificant decrease in soil pH for both growing seasons and a significant increase in soil moisture contant for both seasons as compared with control treatment.However ,sulphur at 500However,sulphur at 410 kg S.haˉˡ caused asignificant decrease in soil Ec during the secand growing.The time period caused asignificant decrease in soil pH and Ec soil during both seasons wheres soil moisture contant increased significant as the time period increased ,2 - Vegetative growth characteristics The addition of K humate at 255 and 510 kg K.haˉˡ caused a significant increase in plant length and number of side shoots during both growing seasons ,as compared with control treatment . Those two levels of K humate also caused asignificant increase in stem diameter ,total leaf number and both fresh and dry weight of the plant during the secand of growing season.However ,K - humate at 72 kg .haˉˡ caused asginificant increase in leaf area during both growing season ,where the increase in total leaf number and fresh weight of the plant was for the first growing season only.Sulphur at 205 and 410 kg S.haˉˡ caused a significant increase in plant length ,leaf area and plant dry weight during both growing season whereas the levels of Khumate had a significant effect with respect to plant from weight during the first growing season ,and total leaf number during the secand growing season.However ,the addition of Khumate at 410 kg S.haˉˡ induced asignificant increase in leaf number of side shoots during the first growing seaeon as compared with the level 205 kg S.haˉˡ and control treatment .The level 410kg S.haˉˡ caused asignificant increase in plant fresh weightduring the second growing season as compared with the level 205 kg S.haˉˡ .3 - flowering characteristics.The addition of K - humate of 255 and 510 kg K.haˉˡ caused a significant increase in number of inflorescens ,number of flowers per inflorescens during both growing season compared with control treatments .However ,both levels reducal the percentage of flower abortion during the first growing season .At 510 kg K.haˉˡ percentage flower decreased as compared with 36 kg K.haˉˡ and control treatment. Sulphur treatment at 205 and 410 kg S.haˉˡ reduced the percentage of flower aboration significant as compared with control treatment during the first growing season.At 410 kg S.haˉˡ ,sulphur ,that was a significant increase in number of inflorescane as compared with contror during the first growing season .cowever ,sulphur had no significant effect on number of flowers per inflorescence during both growing seasons .The interaction treatments had no significant effects ,with the exception of percentage flower aboration during the first growing season.K humate at 510 kg K.haˉˡ caused asignificant decrese in percentage flower abortion as compared with K humate at 255 kg K .haˉˡ during the secand growing season.The addition of sulphur at 205 and 410 kg S.haˉˡ reduced the percentage of flower abortion significantly as compared with control treatment during the first growing season.However, sulphur at 410 kg S.haˉˡ increased significantly the number of inflorescence as compared with control duringthe first growing season .Sulphur had no significant effect on flower number prr inflorescence for both seasons.4 - Leaf chemical constituents.The addition of K humate at both levels(255 and 510 kg K.haˉˡ ) caused a significant increase in total soluble carbohydrates,K+/ Na+ ratio and a significant decrease in chloride ion during both growing season.There was also a significant in total chlorophylls, proline, and percentage of N,P,K,S,Mg and Ca during the first growing season only.There was a significant increase the percentage of K+ and adecrease in Na+ ion during the second growing season .K humate at 510 kg K.haˉˡ caused asignificant increase in total chlorophylls and proline and percentage of S and Ca during second growing season.Plantfertilized with sulphur at 205 and 410 kg S.haˉˡ had asignificantly higher concentrations of total soluble carbohydrates ,total chlorophylls and percentage of N,P,S,Mg during both growing seasons as compared with control plants such treatments also caused a significant increase in percentage K+ ion,K+/Na+ ratio during the first growing season.However ,proline content,Ca++ ion was significantly increased, wheras chloride ion (CLˉ) was significantly decreased due to sulphur fertilization,during the second growing season .Sulphur at 410 kg S.hˉˡ caused a significant increase in percentage of Ca++ during the first growing season,and K+ ion during both growing season in comparison with 250 kg S.hˉˡand control treatment.5 - Quantitative yield.Plant fertilized with K humate at 255 and 510 kg S.haˉˡ had a significantly higher average fruit weight during both growing seasons ,fruit number and plant yield and total yield during the first growing season and early yield during the second growing season however supplying K humate at 510 kg K.haˉˡ had a significantly higher early yield during the first growing season and in fruit number ,plant yield and total yield during the second growing season.As for fertilization with agricultural sulphur, plant fertilized with 250 and 410 kg S.haˉˡ had a significant higher fruit weight as compared with control treatment during both season fruit number ,plant yield during the first growing season and early yield during the second growing season .Sulphur fertilizer at 410 kg S.haˉˡ had a significantly higher fruit number,plant yield and early and total yield during the second growing season compared with control treatment.There was a significant interaction between studied factors in certain characteristics and both growing seasons.6 - Qualitative yield.Tomato plants fertilized with K humate at 255kg K.haˉˡ had a significantly higher total titratable acidity percentage during both growing seasons ,vitamin C contant during the first growing season ,and percentage dry matter during the second growing season in comparion with control treatment.Plants fertilized with 510 kg S.haˉˡ had a significantly higher total soluble solids content during both growing season and in percentage dry matter during the first growing season and vitamin Ccontent during the second growing season.Plant fertilized with agricultural sulphur at both levels (205 and 410 kg S.haˉˡ )had asignificantly highr total titratable acidity during both season asecompared with control treatment, and percentage matter during the second growing season.Plants fertilized with sulphur at 410 kg S.haˉˡ had a significantly higher percentage dry matter and vitamin C content during second growing season.7 - Storage behavior.A - Storage at room temperature 25±1c .Storage at room temperature percentage fruit decay and loss in weight decreased significantly for fruit fertilized with K humate at levels of 36 and 510 kg K.haˉˡ ,and there was an increase in total soluble solids.Also,fruit decay percentage significantly decreased and total soluble solids increased in fruits of plants fertilized with sulphur at 205 and 410 kg S.haˉˡ during both growing seasons,and adecrease in weight loss during second growing season ,however,sulphur at 410kgS.haˉˡ caused a significant decrease in percentage season.Percentage fruit decay ,weight loss and total soluble solids increased ,with increasing storage period during both growing season .However vitamin C content decreased with increasing storage period .B - The cold storage 5±1 c.Both percentage fruit decay and percentage loss in weight decreased whereas total soluble content increased in fruit of plants fertilized with potassium humate at the levels of 255and 510 kg K.haˉˡ significantly as compared with fruit of control plants and for both growing seasons .Also,the percentage loss in weight for fruits of plants fertilized with agricultural sulphur at 205 and 410 kg K.haˉˡ ,decreased significantly for both growing seasons.Percentage fruit decay decreased significantly during the first growing season as well as an increase in total soluble solids during the first growing season.However sulphur at 410 kg S.haˉˡ caused asignificant decrease in fruit decay percentage during the second growing season and an increase in total soluble solids during the first growing season.Decay percentage,percent of weight loss, and total soluble solids and titratable acidity increased with increasing storage period .There was also adecrease in vitamin C contant with increasing the storage period for both growing seasons.The method of storage had a significant effect on studied characteristics,as cold storage caused a significant decrease in percentage fruit decay during both seasons and weight loss during the first growing season ,as compared with storage at room temperature.However,storage at room temperature caused asignificant increase in ascorbic acid content ,and total titratable acidity of the fruit as compared with cold storage and for both growing season .The total soluble content of the fruits increased for there stored at room temperature as compared to cold storage during the first growing season only.
