Effect of some new post-emergence herbicides on weed parameters and seed yield of soybean [Glycine max. (L.) Merrill]

摘要

A field experiment was conducted during the kharif season of 2001-02 at Research Farm, College of Agriculture, Indore, on clay loam soil to study the effect of post-emergence herbicides and their doses on the weed parameters, seed yield of soybean [Glycine max (L.) Merrill], plant height, number of triplicates, dry matter per plant, yield attributes and seed yield of soybean, weed dry matter and weed density were significantly affected by herbicides. Higher seed yield and seed production efficiency were obtained under weed free upto 60 DAS after sowing and with 1 IC+(Imazethapyr+lmazamox-FP) 25 g/ha post-emergence (20 DAS).
