An attempt has been made to study the effect of manganese sulphate and potassium silicate on rust incidence, yield and yield components of rust susceptible and resistant soybean genotypes. The results revealed that the Asian soybean rust (ASR) severity was signifi¬cantly reduced on plants sprayed with manganese sulphate in comparison to plants sprayed with potassium silicate and control. Leaf manganese and potassium contents increased significantly with the application of manganese and potassium. Resistant genotypes had 46 per cent higher leaf manganese content than in the susceptible genotypes. Manganese not only reduced rust but also improved plant height and number of branches and seed yield. In conclusion, manganese sulphate alone was more effective than potassium silicate and their combinations. Rust resistant soybean genotype DSb 23-2 was better against rust giving highest yield as compared to rest of the susceptible and resistant genotypes.
