Influence of different tillage and weed management practices on growth parameters and chlorophyll content of soybean in sub humid Rajasthan

Abstract

A field experiment was conducted at Rajasthan College of Agriculture, Udaipur during Kharif 2007 and 2008 to evaluate the feasibility of tillage and weed management practices for obtaining maximum growth parameters and chlorophyll content of soybean comprised ten treatments laid out in split plot design with three replications. Conventional tillage gave significantly highest plant height, dry matter accumulation, stover and biological yield and highest chlorophyll content. Hand weeding twice gave significantly highest plant height, RGR, CGR, seed yield, stover yield and highest chlorophyll content. Next best treatment were rotavator tillage and imazehapyr100 g ha-1, with respect to above parameters amongst all weed control and tillage practices.
