Use of Barley Residue Water Extract Combined with Pendimethalin Herbicide for Weed Control in Mungbean

Abstract

M (Vigna radiata L.) is an important summer pulse crop and provides easily digestible proteins (Nazir, 1994). Weeds are a major problem in rainfed mungbean. Weeds can reduce yield of mungbean upto 67% as compared to weed free conditions (Yadav and Singh, 2005). The herbicide use for weed control is expensive and continuous use of herbicides has created problems of weed resistance and environmental pollution (Shahid et al., 2006) and can also affect the quality of many crops (Nazarko et al., 2003). Use of Allelopathic properties of crop residue for weed control is a natural and an environment-friendly practice that can decrease our reliance on synthetic herbicides (Minorsky, 2002).
