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 significantly reduced on plants sprayed with manganese sulphate in comparison to plants sprayed with potassium silicate and control. | Nội dung Text Effect of foliar application of manganese and potassium on rust susceptible and resistant soybean genotypes
