Weed management in cowpea [Vigna unguiculata (L.) Wasp.] under rainfed conditions

Abstract

A field experiments was conducted for two consecutive Kharif seasons of 2012 and 2013 at Rajasthan Agricultural\rResearch Institute, Durgapura, Jaipur to study the effect of weed management practices on cowpea under rainfed conditions.\rResults revealed that application of imazethapyr + imazemox @ 40 g ai/ha at 20 days after sowing (DAS) recorded lowest dry\rweight of both monocot and dicot weeds with highest weed control efficiency (84.8%). However, maximum seed yield (9.04 q/ha),\rnet returns (Rs. 24718/ ha) and B:C ratio (3.46) was obtained under application of imazethapyr @ 40 g/ha at 20 DAS.
