Influence of weed control methods on growth, yield and economics of rainfed soybean (Gtycine max) at farmer s field

Abstract

A field experiment conducted at farmer s field during 1998 and 1999, on weed control methods in soybean [Glycine max (L.) Merr.] showed that pendimethalin Q 1.0 kg a.i./ha (pre emergence application) t hand weeding resulted in significantly higher growth, yield attributing characters, and seed yield over rest of the methods including control (farmer s practice). Significantly lower number of weeds/m2 and weed dry matter were obtained with the use of pendimethalin supplemented with 1 hand weeding. This treatment also gave the 7, highest weed control efficiency during both the years. The highest benefit : cost ratio was obtained with the use of pendimethalin alone.
