EFFECT OF LEAF NUTRITION BY IRON AND MANGANES IN YIELD AND QUALITY OF THREE SOYBEAN CULTIVARS .

Abstract

A field experiment was conducted in a mixed sand textured soil during summer season at 2009 in AL- Anbar Governorate to know the effect of three levels leaf nutrition by iron and manganese sulfate mixed together 0 , 50+50 ,100+100m.g./L in yield and quality of three soybean cultivars LS74, Geza 22 and Geza 83. A factorial experiment arrangement in Randomized Complete Block Design with three replicates .Soybean cultivars showed a different significant . The cultivar LS 74 gave a highest average in : number of pods .plant-1, percentage of fertility in the pods and seeds yield 3.02 t.ha-1.. The spraying of Iron and Manganese showed a significant effect for all traits . The leaf nutrition in a level 50+50 m.g./l gave a highest rate in : number of pods.plant-1 109.4 pod , percentage of fertility 92.63% ,100 seeds weight 12.67 gm , seeds yield 3.22 t.ha-1, and protein percentage in the seeds 35 %.while the spraying of this leaf nutrition in a level 100+100 m.g./l gave a highest rate in number of seeds . pod-12.52 seed only . .The interaction between cultivars and spraying Iron and Manganese was significant effect in seeds yield . The treatment LS74 with 50 +50 m.g / L gave 3.55 t /ha .
