Integrated Weed Management Practices on Productivity and Profitability of Direct Seeded Rice under Aerobic Condition

Abstract

At the research farm of RPCAU, Pusa, Samastipur, Bihar, a field experiment was carried out during the 2017 kharif season to examine the effects of integrated weed control on the profitability and productivity of direct-seeded rice grown in aerobic conditions. The experiment was laid out in Randomized Block Design having ten treatments with three replications. Both hand weeding and herbicidal treatments, out of all the weed control techniques, had noticeable effects on crop development and yield as well as their superiority to the weedy check. Hand weeding at 20, 40 and 60 days after sowing was found significantly superior over all the integrated weed management practices on productivity and profitability of dry direct seeded rice. Pendimethalin @ 1 kg/ha at 0–2 days after sowing, followed by two hand weedings at 20 and 40 days after sowing, outperformed the other herbicidal treatments in the trial for dry direct seeded rice.
