Effect of integrated weed management practices on weed dynamics of dry direct seeded rice (Oryza sativa L.)

A field experiment was conducted during the kharif season of 2017 at the research farm of RPCAU, Pusa, Samastipur, Bihar to study the, Integrated weed management practices on weed dynamics and grain yield of Dry Direct Seeded Rice. The experiment was conducted in Randomized Block Design having 10 treatments with 3 replications. Among all the weed management practices both hand weeding and herbicidal treatments had reflective effect on weed population and weed dry matter accumulation as well as reflected in their superiority over the weedy check. Hand weedings at 20, 40 and 60 DAS was found significantly superior over all the integrated weed management practices on weed growth of dry direct seeded rice. Amongst herbicidal treatments Pendimethalin @ 1 kg/ha at 0-2 DAS fb two hand weedings at 20 and 40 DAS was superior on to rest of all herbicidal treatments for dry direct seeded rice during the year of experimentation.
