Abstract:

A field experiment was conducted at Research farm of Department of Agronomy, CCS Haryana Agricultural University, Hisar, during Kharif season of 2013 to evaluate different weed control treatments on weed dynamics, phenology, heat unit requirement and productivity of green gram. The experimental field was infested with both types of weeds. RM of imazethapyr + imazamox (RM) at 80 g/ha applied at 3-4 leaf stage recorded highest value of WCI (80.68), CRI, GDD, HTU, PTU, calendar days, HUE, HeUE, PUE and seed yield (398 kg/acre) and lowest value of total weed population , weed index (13) over other herbicidal treatments. Two (hand) hoeings employed at 20 and 40 DAS gave statistically at par results with weed free treatment followed by one (hand) hoeing. Post-emergence application of RM imazethapyr + imazamox (RM) at 60-80 g/ha exhibited 74-80% control of weeds and showed higher crop growth. In sight of results, two hoeings at 20 and 40 DAS or post emergence application of imazethapyr + imazamox at 80 g ha-1 or imazethapyr alone at 70 g ha-1 should be adopted for the control of weeds in green gram.
