Cumulative effect of tillage and weed management practices on soil property, weed dynamics and productivity of mungbean (Vigna radiata L.) in rice-wheat-mungbean cropping system

Abstract

A field experiment was conducted during 2014-15 and 2015-16 at DWR, Jabalpur (M.P.) to see the Cumulative effect of tillage and weed management practices on soil property, weed dynamics and productivity of mungbean (Vigna radiata L.) in rice-wheat-mungbean cropping system. Fifteen treatments, comprising of five tillage practices as main-plot and three weed management practices as sub-plot treatments were laid out in split plot design with three replications. Zero tillage in mungbean after zero tillage in rice and wheat with or without previous crop residues has lower soil pH, higher EC, OC, N, P, K content and weed density. Whereas, zero tillage in mungbean after conventional tillage in mungbean with previous crop residues reduces the bulk density and enhances the crop growth and gave higher seed yield with better weed control than other treatments. Similarly, regular or rotational use of herbicides equally control weeds in mungbean and gave higher seed and stover yield of mungbean.
