Abstract:

Present study was undertaken to evolve an efficient and reliable measure for management of sheath blight of rice through application of judicious doses of plant nutrients. In this investigation, the effect of different doses i.e. control dose (naturally available in soil), deficient dose, recommended dose and excess dose of macronutrients (N, P &K) & micronutrients (S, Zn & Fe) were assessed on incubation period for first appearance of sheath blight, disease severity and on phenolic contents in inoculated rice plants. The experimental results exhibited that enhancement in dose of nitrogen and phosphorus, decreased the incubation period of sheath blight and phenolic contents in inoculated rice plants and increased the sheath blight severity. However, enhanced dose of potassium increased incubation period and quantity of phenols in inoculated rice plants and decreased the sheath blight severity. Application of recommended dose of sulphur increased incubation period and phenolic contents in inoculated rice plants and decreased disease severity, followed by excess or deficient dose. Recommended dose application of zinc or iron resulted in increased incubation period and phenolic contents and decreased sheath blight severity followed by deficient dose. Application of excess dose of zinc or iron reduced incubation period and phenolic contents up to a greater extent and increased sheath blight severity.
