Abstract

The study conducted with pre-emergent herbicides alone and with sequential application of post-emergent herbicides at All India Co-ordinated Research Project (AICRP) on Weed management, Gandhi KrishiVignyan Kendra (GKVK), Bangalore in late rabi season of 2013 revealed the predominance of grasses over broad leaved weeds in blackgram. Interculture @ 20 days after sowing (DAS) and hand weeding @ 40 DAS resulted in higher yield (1182 and 5873 kg ha-1 seed and haulm yield, respectively) and least weed density of 41.33 m-2 during harvest. Uncontrolled weed growth recorded maximum population (70.00 m-2). During initial days pendimethalin 30 EC @ 0.75 kg a.i. ha-1 and alachlor 50 EC @ 1.0 kg a.i. ha-1 recorded significantly least weed population of 29.33 m-2at p< 0.05 level of significance. Uncontrolled weed growth resulted in maximum reduction in yield of 65.64 per cent.
