Influence of weed-control method on productivity of rainfed soybean (Glycine max) in Vertisol of central India

Abstract

A field experiment was carried out during the rainy season of 1998 and 1999 to study the effect of different herbicides on growth and yield of 'JS 335' soybean [Glycine max (L.) Merr.] grown on clay-loam soil of Indore, Madhya Pradesh. The conventional practice of weed control involving dora (a small bakhar shape implement, drawn by a pair of bullocks between the rows of the crop) and 1 hand-weeding 30 days after sowing the crop, was effective in controlling the weeds and giving higher grain yield. The pre-emergence application of herbi- cides-metolachlor @ 1.0 kgtha, chlorimuron ethyl @ 0.009 kgtha and combined use of chlorimuron ethyl and metolachlor @ 0.009 kg and 1.0 kgtha, respectively, were equally effective in controlling the weeds and influenc- ing soybean yield favourably.
