Influences on Growth Parameters and Yield of Various Moisture Regimes and Weed Management Practices on Drum Seeded Rice (Oryza sativa L.)

The field experiment was conducted on Agronomy research farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj Ayodhya UP, (India) during Kharif season 2021 and 2022. The experiment was laid out in split plot design with three replications taking three moisture regimes viz., 6 cm at 1 DADPW, 6 cm at 4 DADPW and 6 cm at 7 DADPW (Days after disappearance of ponded water) in main plot, and four weed management practices viz., control, Organic Mulch (Rice Straw@5t ha-1), Herbicide (Bispyribac sodium (10%) @ 200 ml ha-1 post emergence) and Two hand weeding at 25 and 45 DAS in sub plot. Result revealed that significantly plant height, numbers of tillers, dry matter accumulation, leaf area index and test weight, grain yield, straw yield and harvest index was recorded in 6 cm at 4 cm DADPW during both the years of investigation. Among the weed management practices, higher value recorded with sequential two hand weeding at 25 and 45 day after sowing.
