\begin{abstract}
\normalsize{
In order to evaluate the effects of wheat (\textit{Triticum aestivum} L.) and bean residues (\textit{Phaseolus vulgaris} L.) with application zinc sulfate in wheat farm on zinc, protein, phytic acid concentration in wheat grain and grain yield, an experiment was conducted in the growing season of 2012--2013 in the Isfahan city research farms as complete randomised block design in three replications with six treatments (control, zinc sulfate, wheat residue, bean residue, wheat residue + zinc sulfate and bean residue + zinc sulfate). Results of ANOVA showed the highly significant differences between wheat and bean residues with application zinc sulfate on zinc, protein, phytic acid in wheat grain, phytic acid to zinc molar ratio and wheat grain yield. Analysis of variance also shows that crop residues application on the soil pH and electrical conductivity (EC) were not significant statistically. Among the residues, adding wheat residues to the soil in comparing to control and zinc sulfate treatment increased more organic carbon in soil. The results showed that the highest yield, protein and grain zinc concentration was related to bean residues + application sulfate zinc treatment and the lowest yield was related to control treatment. The plant residues application in all the considering treatments in this experiment, decreased the phytic acid to zinc molar ratio and specially, bean residues + application sulfate zinc treatment in relation to control treatment. Amongst the plant residues, the bean residues had the lowest relation of carbon to nitrogen. The highest wheat grain yield was obtained by bean residues + application sulfate zinc treatment. Finally, bean residue + application  sulfate zinc treatment was better than other treatments due to increasing zinc concentration, protein, phytic acid in wheat grain, phytic acid to zinc molar ratio and wheat grain yield.}
