Abstract: A field experiment was conducted at Research Farm of College of Horticulture and Forestry, Central Agricultural University, Pasighat, Arunachal Pradesh during rainy season of 2013 and 2014. Almost 60 per cent of weed infestation was dominated by grassy and sedges, followed by broad-leaved weeds. Uncontrolled weed growth exerted significant reduction in mean green pod yield of okra by 43.84 and 45.90 per cent during 2014 and 2015, respectively. Application of different doses of Pendimethalin with or without hand weeding provided effective weed control but the late flushes and regenerated weeds at later stages hampered the crop yield. Weed free situation up to 60 days stage provided 67.6 and 60.2 per cent weed control efficiency and 0.99 and 1.01 per cent Weed Persistence Index during 2014 and 2015, respectively. During both the years of experimentation highest green pod yield were recorded in weed free plots while maximum Benefit: cost ratio obtained from plots treated with Pendimethalin 30EC @ 1.5kg ai.ha-1 + one time hand weeding.
