ABSTRACT
Results of an experiment conducted at College Farm, Gujarat Agricultural University, Navsari during summer season of revealed that frequent irrigation at 0.9 IW /CPE ratio increased seed yield of blackgram, weed population and dry weight of weeds. Suppression of weeds by weed control measures resulted in better crop growth and seed yield of blackgram. Two hand weeding at 20 and 40 DAS and an application of pendimethalin @ 0.75 kg ha–1 as pre-emergence alongwith one hand weeding at 40 DAS could successfully reduce the weed population and their dry weight with the highest weed control efficiency which ultimately increased the seed yield of blackgram by 49.44 and 47.4l per cent than unweeded control, respectively.
Key words :
Blackgram, irrigation levels, Phaseolus mungo, weed control efficiency.
