A field experiment was conducted during summer 2009 under irrigation on weed management practices in summer groundnut (Arachis hypogaea L.). The experiment was conducted at the College of Agriculture and Zonal Agricultural Research Station farm, Shimoga, Karnataka, India. Recommend cultural practices recorded a higher pod yield (2880 kg ha -1 ), which was statistically in par (p>0.05) with preemergence application of imazethapyr at 100 g a. i. ha -1 (2791 kg ha -1 ). Application of herbicides recorded a higher weed control efficiency compared to farmer's practice and weedy check. Among the herbicides tested, the pre-emergence application of imazethapyr (100 g a.i. ha -1 ) performed better than alachlor (2.0 kg a. i. ha -1 ), metolachlor at 1.0 kg a.i. ha -1 ) and pendimethalin (1.0 kg a. i. ha -1 ). Pre-emergence application of imazethapyr (100 g a. i. ha -1 ) recorded a higher net returns (Indian 53,220 ha -1 ) and a higher benefit:cost ratio (2.22) among the herbicide treatments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
