Effects of Wheat and Bean Residues along with Zinc Sulfate Application on some Qualitative and Quantitative Characteristices of Wheat

In this study the effects of wheat (Triticum aestivum L.) and bean (Phaseolus vulgaris L.) residues, along with application zinc sulfate, on zinc, protein, phytic acid concentrations of wheat grain and grain yield were evaluated to do this an experiment based on randomized complete block design with 3 replications and six treatments (control, zinc sulfate, wheat residue, bean residue, wheat residue zinc sulfate and bean residue zinc sulfate) was conducted in Isfahan during growing season of 2012-2013. Results of ANOVA showed that there were highly significant differences between wheat and bean residues along with application zinc sulfate, protein, phytic acid in wheat grain, phytic acid to zinc molar ratio and yield. The results also showed that the highest grain yield, protein content and grain zinc concentrations were related to bean residues application sulfate zinc treatment and the lowest yield to control. The use of crop residue on the soil caused a significant increase in grain yield and shoot, as compared with that of the control (p
