Abstract : Application of recommended dose of NP+1 kg K2O through SOP per tree+1 per cent foliar sprays of potassium nitrate produced significantly more fruit yield (78.57 kg tree-1) over absolute control (40.04 kg tree-1). An application of different levels of potassium significantly increased N, K and Ca content in the mango pulp from 0.96 to 1.11, 0.56-1.16 per cent and 15 to 44.11 C mol (p+) kg-1 respectively. Application of different levels of K significantly increased content of N, P, K and Ca in mango leaves at initial, before flowering and post harvest stage. Application of different levels of K significantly influenced the chemical properties of soil such as available N, P, K and exchangeable calcium at post harvest stage.
