Abstract: A field experiment was conducted to study the effect of weed control methods on weed dynamics and productivity of okra during kharif season of 2016 and 2017 in a randomized block design. The treatments comprised of nine weed control methods, consisting plastic mulch, available weeds mulch, straw mulch, cover crop: Sesbania aculeata (Dhaincha), oxyfluorfen 0.20 kg/ha PE, pendimethalin 1.0 kg /ha PE, mechanical weeding by Dutch hoe, hand weeding at 20, 40, 60 days after sowing (DAS) and weedy check. Plastic mulch being similar to hand weeding recorded significantly reduced weed density of grassy, broad leaved and sedges as well as total weeds. The reduction was to the extent of 99.27, 90.28, 95.52 and 94.50 percent respectively compared to weedy check. Similarly, the reduction in total weed dry weight was 93.87 percent compared to weedy check. The corresponding reduction in weed density compared to common practice of weed control i.e. hand weeding were 94.11, 50.29, 51.16, and 62.54 percent while the reduction in total weed dry matter was 85.00 percent. Application of plastic mulch recorded 714.90 and 107.68 percent higher okra yield compared to weedy check and hand weeding respectively. However maximum net return and B:C ratio was observed by application of straw mulch and was similar to available weed mulch compared to other treatments.
