Effect of weed management practices on growth and yield of Blackgram (Phaseolus mungo L.)

Abstract

A field experiment was conducted during Zaid (summer) season of 2023 at Crop Research Farm Department of Agronomy. The experiment consisted of eight treatments laid out in Randomized Block Design and replicated three. The treatment consisted of pre-emergence application of Pendimethalin at 1.0 kg/ ha, post-emergence application of Imazethapyr at 80 ml/ha, Imazamox at 50 ml/ha and their combinations pendimethalin at (750 ml/ha) +Imazethapyr at (40 ml/ha) and pendimethalin at (750 ml/ha) + Imazamox at (25ml/ha) and along with two hand weddings at 15 and 30 DAS and a control. Minimum weed population (4.69), weed dry weight (g/m2) (9.17) and pod/plant (31.40), seed/plant (8.60), test weight (36.20 g), seed yield (1185 kg/ha) was recorded in treatment 6 with pre-emergence application of pendimethalin was applied at (750ml/ha)+Imazethapyr at (40ml/ha).
