بررسی صفات مورفولوژیکی وابسته به عملکرد هیبریدهای ذرت دانه‏ای در شرایط محلول پاشی سولفات روی در اهواز

In order to study the Morphological Traits Depending on the yield of Corn Hybrids in Zinc Sulfate Spraying Condition, an experiment was done in summer 2011-2012 in the form of split plot based on randomized complete block design (RCBD) with three replications. The main factor included zinc Sulfate spraying in four levels (without spraying, spraying at the stage of eight leaves, spraying at the stage of twelve leaves and simultaneous spraying at the stages eight and twelve leaves) and the second factor included corn hybrids (K.S.C701 corn hybrid and K.S.C704 corn hybrid). The results indicated that zinc Sulfate spraying had significant effect on traits of Total ear weight, total grain ear weight and Biological yield. For all of the traits except Harvest index, the maximum amount belonged to in K.S.C701 corn hybrid while zinc sulfate spraying at the stages eight and twelve leaves, and the minimum amount was in K.S.C704 corn hybrid while treatment without spraying. There was a significant difference between under experiment hybrids according to the length of the corn, Total ear weight, total grain ear weight, Grain yield, Biological yield and Harvest index. Mutual effect of zinc sulfate and hybrid had no significant in any traits. The results of this research indicated that, the reaction of different hybrids to different treatments such as zinc sulfate is distinct, and this status is dependent on differences between hybrids.
