Herbicide Options for Suitable Weed Management of Transplanted rice in North-Eastern Ghat Zone of Odisha

A field study aimed to assess different weed management tactics in transplanted rice was demonstrated during rainy season in four villages of Ganjam district of Odisha under farmer participatory mode for two years (2019 and 2020). From the concluded research work, it was observed that application of pretilachlor (0.75 kg/ha) within 3 DAT followed by bispyribac sodium @ 25kg/ha at 25 DAT recorded the highest WCE (73.27%), grain (4186 and 4351 kg/ha) and straw yield (5349 and 5308 kg/ha). Hand weeding performed better with respect to WCE (80.1, 81.3 % at harvest) but net return (Rs. 37073 /ha, Rs. 38119 /ha) was found to be low. While Pretilachlor (0.75 kg/ha) within 3 DAT followed by bispyribac sodium (25 kg/ha) at 25 DAT recorded the highest net return (Rs. 41798/ha, Rs. 43956 /ha) and B:C ratio (1.87, 1.89) than other treatments.
