بررسی مدیریت بقایاء و روش‌های خاک‌ورزی بر ویژگی‌های مرتبط با همزیستی در سویا

Plant residues have many applications, including are a haven for micro-organisms, dirt, rain barriers, animal feed, fuel consumption and soil amendment. To evaluate the influence of crop residue management and tillage methods on some characteristics associated with plant and microbial symbiosis in soybean Strip-plot experiment was conducted as a randomized complete block design with three replications to investigate the effect of different crop residue management and tillage methods in Gorgon Agricultural Research Station Research Center for Agriculture & Natural Resources province. Analysis of variance indicated that the treatments had a significant effect on traits. For example, the effect of residue management on microbial respiration different significantly at 1% level. The effect of tillage methods had no significant effect on soil respiration at the 5% level. Also, there was a correlation between the number of nodes with a dry weight of nodules and plant respiration significant at 1% level, with correlation coefficients equal to 0.935.
