Abstract

A field study was carried out during the rabi season 2020-21 to identify weed species andinvestigate the efficacy of post-emergence herbicides on weeds and their effect on wheat grainyield at AICRP on Wheat, JNKVV, Jabalpur (M.P.). Seven different treatments were applied,namely pinoxaden at 40 g a.i./ha, pinoxaden at 45 g a.i./ha, pinoxaden at 90 g a.i./ha, clodinafoppropargyl at 90 g a.i./ha, sulfosulfuron at 25 g a.i./ha as post-emergence (25 DAS), hand weedingat 30 DAS and weedy check. The highest number of individuals was recorded for Medicagodenticulata (30.82%), Cichorium intybus (29.94%), Phalaris minor (15.60%), Chenopodium album(15.32%) and Anagallis arvensis (8.30%). All the herbicide treatments provided significant controlof weeds causing significant reduction in density of target weed flora and improved the grain yieldcompared with the weedy check. The highest mortality of weeds (41.12%) was recorded wherepinoxaden at 90 g a.i./ha was applied. However, pinoxaden at 45 g a.i./ha is the most effective andbest option for higher values of growth parameters, yield attributes and maximum wheat grainyield
