摘要
在 2022 年的旱季进行了一项田间试验，以评估直播稻在不同配方的新一代除草剂作用下的生长和产量反应。结果表明，在出苗前 7 DAS 施用 0.6% 的苄嘧磺隆 + 6% 的丙草胺 @ 10 kg ha-1，40 DAS 手工除草，可广泛防除杂草。最高的作物生长属性（分蘖/丘、叶面积指数和总干物质）、产量属性（多产分蘖、灌浆谷粒/穗、穗粒重）和谷物产量（6670 千克/公顷-1）、净收益（94991 卢比/公顷-1）以及最高的每卢比投资收益（2.在出苗前 7 DAS 施用 0.6% 的苄嘧磺隆 + 6% 的丙草胺 @ 10 kg ha-1，并在 40 DAS 进行人工除草时，记录到苄嘧磺隆 0.6% + 丙草胺 6% GR @ 10 kg ha-1，这是最好的广谱高效除草剂，可最大程度地减少直播稻的杂草种类。
Response of Direct Seeded Rice Under Different Formulation of New Generation Herbicides on Growth And Yield
A field experiment was conducted during kharif season of 2022 to evaluate the growth and yield response of direct seeded rice under different formulation of new generation herbicides. The results revealed that, pre emergence application of bensulfuron methyl 0.6% + pretilachlor 6% GR @ 10 kg ha-1 on 7 DAS fb hand weeding on 40 DAS recorded broad spectrum of weed control. The highest crop growth attributes (tillers/hill, leaf area index and total dry matter), yield attributes (productive tiller, filled grains/panicle, panicle weight) and grain yield (6670 kg ha-1), net returns (Rs.94991 ha-1) and the highest returns per rupee invested (Rs.2.77) were recorded in pre emergence application of bensulfuron methyl 0.6% + pretilachlor 6% GR @ 10 kg ha-1 on 7 DAS fb hand weeding on 40 DAS, which was best broad spectrum effective herbicide in order to minimize the diverse weed flora in direct seeded rice
