Abstract
To study the effect of a few herbicides on weed dynamics and yield of summer greengram (Vigna radiata L.), a field experiment was conducted on loamy sand soil during summer season of 2020. Digitaria sanguinalis, Cynodon dactylon, Eleusine indica and Dactyloctenium aegyptium among monocot and Digera arvensis, Portulaca oleracea, Trianthema monogyna and Phyllanthus niruri, the dicot weeds were dominant in experimental field. The pre-emergence application (PE) of either pendimethalin 750 g/ha or pendimethalin + imazethapyr (pre-mix) 750 g/ha or oxyfluorfen 117.5 g/ha PE or inter-cultivation twice and hand weeding twice at 20 and 40 days after seeding (DAS) significantly reduced the density and biomass of monocot and dicot weeds in summer greengram. These treatments recorded higher greengram growth, yield attributes, viz. plant height plant dry biomass, nodule dry weight, number of pods/plant, seed yield and benefit cost ratio (B:C).
