Abstract: 

Crop residue management is one of the main pillars of the stabilization of agricultural ecosystems. In order to evaluate the effects of wheat (Triticum aestivum L.) and bean residues (Phaseolus vulgaris L.) with application zinc sulfate (ZnSo4) in wheat farms on zinc and iron available in soil, roots, shoots, grain and protein of grain wheat, an experiment was conducted in the growing season of 2012-2013 in research farm of Isfahan city, as complete randomized block design with three replications and six treatments (control, zinc sulfate, wheat residues, bean residues, wheat residues with zinc sulfate and bean residues with zinc sulfate) that was mixed with soil under severe available zinc deficiency and iron respectively (0.3, 4.8 mg per kg) then wheat plants were cultivated. The results showed that the addition of plant residues in soil increased, zinc and iron, of soil, root, shoot, grain and its protein and there was significant difference between the control and other treatments. This increase was higher in the bean residue than other treatments except control. The use of crop residue on the soil caused a significant increase in grain yield and shoot in comparison to the control (p<0.01), as the bean residue caused a 20% increase in grain yield but the highest grain yield 35% was obtained more than control (2.8 t/ha) when the bean residue + zinc (3.8 t/ha) was added to the soil. In general the results showed that bean residue + zinc sulfate was better than other treatments for increasing plant traits.
