Influence of weed management practices on direct-seeded rice grown under rainfed and irrigated agroecosystems

Rice seedlings and weeds emerge concurrently in direct-seeded rice (DSR) production systems, while there is no flooding water to inhibit weed germination, emergence development at crop emergence. Because of this, are considered the biggest living barrier DSR significantly reduce yield. The purpose research was devise an approach for management cultivated under various agroecosystems, optimizing growth utilizing herbicides or herbicidal combinations. impacts several techniques were assessed determine most efficient cost-effective managing CoA, JNKVV, Jabalpur (MP) during 2019 rainy season spilt plot design with 2 main treatments viz., rainfed agroecosystem, irrigated agroecosystem 8 sub-plot treatments, i.e. different herbicide hand weeding weedy check. Further parameters as well yield attributes documented. Conventional statistical used evaluate data. Bispyribac sodium dose 25 g/ha efficiently controlled both narrow broad leaved agroecosystems. Highest recorded agroecosystems compared treatment bispyribac produced greatest values indices maximum (3.68 t/ha), exception manual weeding.
