Abstract
A field experiment conducted at IIRR, Hyderabad with three crop establishment methods (normal transplanted rice, mechanized SRI and wet DSR) as main plot treatments and sensor based irrigation management practices (alternate wetting and drying with 5, 10, 15 cm depletion of water level below the soil surface and continuous flooding) as subplot treatments in split plot design on clay loam soil. Significantly least weed abundance was observed in normal transplanted rice and with mechanized SRI with continuous flooding irrigated conditions during rabi seasons of 2021 and 2022. Wet direct seeded rice exhibited severe weed infestation (significantly high weed density and weed drymatter) under alternate wetting and drying conditions compared to mechanized SRI and normal transplanting method.
