Impact of different weed management practices on yield attributes of blackgram (Vigna mungo L.)

Abstract

Field investigation was carried out during the post-Kharif season of 2020-2121 in Bairister Thakur Chhedilal College of Agriculture & Research Station, Sarkanda, Bilaspur (C.G.). The results showed that treatment T3 - (Two hands weeding at 20 and 40 DAS) has recorded maximum number of pods plant-1, number of seeds pod-1, test weight, seed yield, straw yield and harvest index. The higher weed control efficiency and weed control index was also recorded maximum in T3 (Two hand weeding at 20 and 40 DAS) followed by treatment T4 - (Pendimethalin 30EC @ 1kg ha-1 as pre-emergence). The treatment T3 - (Two hand weeding at 20 and 40 DAS) registered highest gross return, net return and B:C ratio, followed by treatment T4- (Pendimethalin 30EC @ 1kg ha-1 as pre-emergence).
