ABSTRACT: In direct seeded rice (DSR), flushes of weeds are encountered, and mostly subsequent herbicides need to apply to control weeds that appear later. A farmer friendly approach was hypothesized in present study to integrate the management strategies for water, soil and cost effective weed free rice production. Efficacy of various herbicides in weed control to improve the performance of aerobic rice grown under varying tillage and alternate water regimes was evaluated. Five weed management techniques (weedy check, weed-free, pendimethalin followed by manual weeding, pendimethalin + bispyribac sodium (BS) + bensulfuron (B) and pendimethalin + MCPA) were carried out within the alternate wetting and drying (AWD) regimes (15 and 20 cm depth) under two... |
