Title: Influence of Date of Sowing, Weed Control Measures and Row Spacing in Soybean (Glycine max)
Abstract: The field experiment was conducted during the rainy seasons of 1993 and 1995 at National Research Centre for Weed Science, Jabalpur to study the influence of date of sowing, weed control measures and row spacings in soybean. The field was mainly infested with Commelina communis (L.), Alternanthera sessilis (L.), Corchorus trilocularis (L.), Echinochloa colonum (L.), E. glabrescence (L.) and Cyperus iria (L.). Presence of weeds throughout the crop growth period caused 59.50% reduction in grain yield of soybean. Delayed sowing (15 July) and narrow row spacing (22.5 cm) reduced the density and dry matter of weeds. However, the maximum yield of soybean was recorded with timely sowing (25 June) and wider row spacing (45.0 cm). Application of herbicides significantly reduced the density and dry matter of weeds and increased the grain yield of soybean. Among different herbicides, fluchloralin at 1.25 kg/ha was found most effective followed by pendimethalin at 1.25 kg/ha and fluazifopbutyl at 0.3 kg/ha.
