Abstract

This research was carried out as a factorial based on a randomized complete block design with four replications at greenhouse conditions. First factor was corn cultivars (D.C370, S.C647 and S.C704) and second factor included 3 levels of residual plant (without residual, root residual, root and shoot residual of wheat). The results showed that percent and mean emergence time, leaf area, biologic and kernel yield, number of kernels per ear, number of kernels per row and ear length was influenced of wheat residual, and maximum positive effects on mentioned traits, obtained at root and shoot residual of wheat. 100-kernel weight and plant height of cultivars showed significant difference. Effect of residual plant on biologic yield, kernel yield, number of kernels per ear, number of kernels per row of S.C704 wasn’t significant, but other hybrids showed significant difference to residual wheat. 100-kernel weight, row number per ear, ear length and plant height of D.C370 was less than other hybrids, significantly.
