A field study was conducted at Research Station in Kota, Rajasthan during rainy (Kharif) season of 2020 to identify suitable herbicides including pre-emergence (PE) and post-emergence herbicides (PoE) for managing weeds and improve productivity of blackgram [Vigna mungo (L.) Hepper]. Among weed control treatments tested, the lowest weed density, weed index and highest crop growths parameters like plant population, plant height, dry matter accumulation, nodules/plant, dry weight of nodules was recorded with hand weeding twice at 20 and 40 days after sowing (DAS), pre-emergence application (PE) of pendimethalin 1.0 kg/ha followed by (fb) post-emergence application (PoE) of propaquizafop 2.5% w/w 33.3 g/ha + imazethapyr 3.75% w/w (pre-mix) ME 50 g/ha at 20 DAS and pendimethalin 1.0 kg/ha PE fb fomesafen 11.1% w/w 220 g/ha + fluazifop-p-butyl 11.1% w/w 220 g/ha (pre-mix) PoE at 20 DAS.
