Abstract

The effect of nitrogen, soil compaction and moisture stress on the nodulation, yield and quality of soybean (Glycine max L. Merril.) was studied. Maximum nodule number and nodule weight per plant were obtained with 30 kg N/ha. Moisture stress at pod formation stage was most detrimental to nodule formation. Soil compaction significantly decreased the nodulation. With higher level of N (60 kg/ha), protein content of seed and yield of straw (not of grain) increased significantly. Moisture stress at reproductive stage significantly reduced the yield attributes and seed and straw production. Protein content of seed and straw was also lowered by moisture stress at both the stages. Soil compaction significantly reduced the yield attributes, yield and protein content of seed.
