Field investigation was carried out for two consecutive years (200 I and 2002) to develop an eco-friendly integrated weed management technology for blackgram (Vigna mungo L.) grown under rainfed eco-system of Central Uttar Pradesh. Results revealed that low dose of pendimethalin (0.5 kg ha") followed by one hand weeding done at 60 days after sowing demonstrated intended weed control (67.80% WeE), enhanced higher grain yield (379 kg' ha" or 119.49%) and fetched net monetary return (Rs.3611 ha") due to weed control.
