Evaluation of forage maize yield and soil organic matter content under green manure cultivation

To investigate the effect of different green manures from Gramineae and Brassicaceae families on yield, some agronomic traits forage maize, overgrowth with weeds soil organic matter, an experiment was conducted based a randomized complete block design three replications for consecutive years (2017-2020) at Agricultural Natural Resources Research Education Centre Southern Khorasan. Experimental treatments included control (without application manure) cultivation barley, triticale, canola, arugula their optimum twice densities. The results showed that barley triticale density 865.7 802.9 g m-2, respectively, had higher manure dry mass time returning to soil. Just before maize cultivation, matter average 0.73 % in compared other treatments. Based results, highest yield 45.7 44.9 t ha-1 were achieved after treatment (22.8 20.7 percent more than treatment) both densities, canola yield.
