Abstract

The growth and yield of soybean was determined using two factors viz., methods of sowing (line sowing and broadcasting) and seed rates (40, 60 80 and 100 kg ha -1). Results revealed that leaf area index (LAI) and shoot dry matter weight were higher in line sowing than broadcasting throughout the entire course of development. Significantly highest number of plant population/plot, branches/plant, filled pods/plant, seed and stover yield were obtained in line sowing method. Seed rate significantly influenced all the studied characters except 100-seeds weight. It was observed that LAI, shoot dry matter weight, plant population/plot, plant height, number of unfilled pods/plant and seed yield increased with increased seed rate while number of branches/plant, filled pods/plant and seeds/plant decreased with increased seed rate. Interaction between line sowing and 100 kg seeds/ha gave the highest seed yield (2.76 t ha -1) which was statistically similar to line sowing and 80 kg seeds/ha (2.67 t ha -1).
