Abstract: The Pot culture studies were undertaken to investigate the macro nutrients in rice as influenced by application of Zinc sulphate and foliar application of salicylic acid and Potassium silicate and Brown spot pathogen Bipolaris oryzae inoculation. The results revealed that Soil application of Zinc sulphate @ 25 kg/ ha along with foliar application of plant activator Salicylic acid @ 50 ppm on 15 days after transplanting and Foliar spray of silicon based nutrient potassium silicate @ 3 % recorded the minimum disease incidence and maximum biometrics of rice. Also, The results revealed that the treatments treated with the Application of ZS, SA and PS significantly influenced the micro nutrient contents such as Zn, Fe, Mn, Cu and Si in leaf, stem and grain. Generally application of ZS, SA and PS increased the Si, Zn and Cu content in leaf stem and grain. Whereas Fe and Mn content are reduced due to application of ZS, SA and PS in rice leaf stem and grain.
