EFFECT OF SEED COATING ON YIELD ATTRIBUTES AND YIELD OF SOYBEAN (GLYCINE-MAX L)

Investigations were carried out during March to June 1991 to evaluate the effect of seed coating with organic, inorganic nutrients and biofertilizers on yield attributes and yield of soybean under three environments with different soil types viz., clay loam, sandy clay loam and sandy loam. Seed coating with bio-digested slurry 50 per cent, superphosphate 2 per cent, Bradyrhizobium 2 per cent, and Phosphobacteria 2 per cent (w/w of seed) increased the number of filled pods and grain yield by 29.6 and 37.2 per cent, respectively over the uncoated. There was a significant increase in the test weight of grains due to seed coating with Phosphobacteria. Environment with clay loam soil was found to be highly responsive to seed coatings.
