Abstract:
During the 2019 kharif season, an experiment was carried out at the Agronomy Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, (C.G.) to ascertain the impact of integrated weed management strategies on the weed dynamics, growth, yield, and economics of wet direct-seeded rice. Post-emergence herbicide (Bispyribac-Na), mechanical and manual weeding, and early post-emergence herbicides (Oxadiargyl and Pretilachlor) were the next steps. Pretilachlor did not perform as well as plots treated with Oxadiargyl. When combined with hand weeding (HW) 35 days after sowing (DAS), Oxadiargyl produced outcomes that were superior to twice the HW plot (T₁₀). When it came to growth parameters, yield-attributing characteristics, and the economics of wet direct-seeded rice, Oxadiargyl @ 70 g/ha at 7-11 DAS fb HW at 30-35 DAS (T₄) outperformed all other treatments and was statistically comparable to the twice HW plot (T₁₀) and Oxadiargyl @ 70 g/ha at 7-11 DAS fb bispyribac-Na @ 25 g/ha at 30-35 DAS (T₂).
