The soil and leaf samples were collected from four mango orchards of Ratnagiri district at five serial stages namely, after harvest of the fruits of previous season, after application of fertilizers, pre-flowering, full flowering and marble stage of fruit for two successive years for the present study. The soil and leaf samples were analyzed for iron, manganese, copper and zinc. The results showed ‘low’ status of available iron, zinc in soil at Dapoli and Pangari locations and deficiency of total Fe content in leaf at all locations which needs to be corrected by additional application of them. In general, all the nutrients of soil and leaf were found to be higher at both the Kelshi locations than Dapoli and Pangari locations during both the years.To improve nutrient status of soil and leaf and to enhance the yield at Dapoli and Pangari locations, it is essential to supply higher quantities of micronutrients through soil and leaf.Further, positive and significant correlations of nutrient content of soil and leaf with yield implied them as a measure of forthcoming yield. From these findings, it can be concluded that for enhancing the yield, it is necessary to maintain optimum nutrient contents in soil and leaf.
