During the kharif seasons of 2014 and 2015, an experiment was carried out to find out suitable method of planting and weed management in greengram crop. The three planting methods (raised bed, conventional and zero till) and nine weed management practices [Weedy check, hand weeding (15 and 30 DAS), weed free, pendimethalin PRE @ 1000 g/ha, imazethapyr PRE @ 70 g/ha, imazethapyr PRE @ 100 g/ha, imazethapyr 3-4 leaf stage @ 70 g/ha, imazethapyr 3-4 leaf stage @ 100 g/ha and imazethapyr+imazamox (RM) 3-4 leaf stage @ 70 g/ha] were adopted using split plot design. Dry matter accumulation in leaves, stem, pods in green gram was significantly higher in bed planting method as compared to conventional and zero till planting methods during both the years. Bed planting method resulted in significantly more number of pods/plant and more number of seeds/pod during both the years of study as growth parameters were improved in bed planting method. Seed yield, being a function of yield attributes, was also significantly more in bed planting method. Biological yield was also significantly more in bed planting method as compared to conventional and zero till planting methods during both the years. Among different weed management practices, maximum dry matter accumulation in leaves, stem and pods was found in weed free treatment. The maximum number of pods/plant and seeds/pod were found in weed free treatment followed by HW (15 and 30 DAS). As yield attributes were improved in all weed management practices compared to weedy check, thus seed yield and biological yield in greengram got improved with adoption of weed management practices as compared to weedy check during both the years of study.
Key words : Dry matter accumulation, greengram, planting methods, productivity, weed management practices
