Abstract

                                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
