Abstract

The results of long term field experiment on maize-wheat rotation after the harvest of 23rd and 24th crop revealed that organic manures and N increased the yield of maize and wheat significantly. The residual effect of organic manures on succeeding wheat yield was more in FYM plots followed by dhaincha, moong, guar and cowpea plots. Significant increase in N uptake by maize and wheat was observed with continuous application of organic manures and N. Organic carbon, available N, P and K contents of soil were greater in FYM plots than green manured plots. Organic manures also enhanced the contents of DTPA-extractable Zn, Cu, Fe and Mn of soil.
