Abstract

An experiment was conducted to evaluate post emergenece herbicides in urdbean crop during Kharif season of 2021-22. Two-hand weeding practices at 20 and 40 DAS, had significantly lower values of dry matter (DM) of different weeds. Application of Imazethapyr 35% + Imazamox 35%WG 70g (T1) recorded significantly lower weed dry matter (g/plant), and higher weed control effieincy (WCE), and remained statistically at par with Sodium Acifluorfen 16.5% 80g +Clodinafop-propargyl 8% EC 165g (T4). Significantly higher grain (1088.91 kg/ha) and stover yields (1442.46 kg/ha) were recorded in T1, compared to others. Imazethapyr 35% SL +Imazamox 35% WG 70g ha-1 POE is recommended on behalf of higher WCE and superior grain yield and economics i.e., Net return and BCR in blackgram.
