Effect of Weed Control on Seed Yield and Stover Yield of Soybean (Glycine max L. Merrill.) Gupta Ankita*, Patel Bhumika Indira Gandhi krishi vishwavidyalaya, Raipur, C.G. *email: 16ankitagupta@gmail.com
Online published on 13 January, 2016. Abstract The present investigation was carried out during kharif season of 2012 at the Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.). The experiment comprised of eight weed management practices viz. W1- Sulfentrazone @ 300 g a.i. ha−1 as PE, W2-Sulfentrazone @ 360 g a.i. ha−1 as PE, W3-Pendimethalin @ 1 kg a.i. ha−1 as PE, W4-Metribuzin @ 750 g a.i. ha−1 as PE, W5-Imazethapyr @ 100 g a.i. ha−1 as PoE, W6-Odyssy 70 WG (imazethapyr 35% + imazamox 35%) @ 100 g a.i. ha−1 as PoE, W7-Hand weeding twice at 20 and 40 DAS and W8-Untreated control, Experiment was laid out in Randomized Block Design with four replications. The soybean variety JS 97–52 was grown as test crop. The result of the experiment indicated that seed yield and stover yield was maximum under hand weeding twice at 20 and 40 DAS which was found comparable with Sulfentrazone @ 360 g a.i. haJ as PE, Sulfentrazone @ 300 g a.i. ha 1 as PE and Imazethapyr @ 100 g a.i. ha−1 as PoE. The lowest seed yield and stover yield was observed under Untreated control. Top | |
