RELATIVE EFFICACY OF PRE AND POST-EMERGENCE HERBICIDES ON PRODUCTIVITY AND PROFITABILITY OF GROUNDNUT (ARACHIS HYPOGAEA L.)Lingampally Shiva Raj Kumar, Pradeep Kumar Knaujiya, Awadhesh Kishore, Jaidev Sharma and Abhinandan SinghAbstract A field experiment was conducted at the Crop Research Centre, School of Agriculture, ITM University, Gwalior (M.P.) during Kharif season 2022. The experiment was conducted with Randomized Block Design and replicated three times and comprised with ten treatments. The herbicides were used individually as well as in combinations viz; T1 to T10. The crop was infested with the different types of weed flora. eg; Dinebra retroflexa and Digitaria sanguinalis of grassy, Amaranthus viridis and Commelina benghalensis of Broad leaved and Cyperus rotundus of sedges group. Weed density of the different weed species and total weeds effected significantly due to different weed management practices. The result indicated that the total weed population and its dry weight weed index were lowest with Pendimethalin (30 % EC) at 1250 g ha-1 (PE) fb hand weeding at 40 DAS. However, highest weed control efficiency was recorded with Pendimethalin (30 % EC) at 1250 g ha-1 (PE) fb hand weeding at 40 DAS, followed by Metribuzin (30% EC) at 350 g ha-1fb hand weeding at 40 DAS. Yield attributes and yield like number of pods plant-1, number of kernelspod-1, Test weight (g), Pod yield (kg ha-1), Haulm yield (kg ha-1), Harvest index were significantly higher with T1; Pendimethalin (30 % EC) at 1250 g ha-1 (PE) fbhand weeding at 40 DAS. |
