Year: 2020

Type: article

Abstract: Field experimentation was conducted during kharif season of 2019 at Research Farm, College of Agriculture, Central Agricultural University, Imphal, India to evaluate the “Effect of tillage and weed management practices on growth and yield of direct seeded rice (Oryza sativa L.) under rainfed condition”. Among the various treatments, the treatment (P2W5) conventional tillage with weedicide Pyrazosulfuron ethyl 10% WP + Fenoxaprop-p-ethyl 9.3% EC recorded significantly higher plant height, number of tillers m-2, plant population, yield attributes and yield, higher weed control efficiency with significant reduction in weed dry matter except for test weight and harvest index which was recorded non-significant. Likewise, gross return (`184066.67 ha-1), net return (`122407.67 ha-1) and benefit cost ratio (1.99) were recorded significantly higher in (P2W5) conventional tillage along with the weedicide Pyrazosulfuron ethyl 10% WP + Fenoxaprop-p-ethyl 9.3% EC whereas the lowest gross return (`116966.66 ha-1), net return (`61932.66 ha-1) and benefit cost ratio (1.13) were obtained from the treatment (P1W1) which was minimum tillage with weedy check.
