Effect of nitrogen, phosphorus and potassium on growth, yield and fruit quality of 'Totapuri' mango (Mangifera indica)

A field trial was conducted during 1985-95 to assess the nutritional requirement. 'Totapuri' mango (Mangifera indica) under rainfed condition at Banglore. Results of a this field trial suggested that, N application significantly influenced the tree growth and fruit yield of young 'Totapuri' trees under rainfed conditions while P and K application did not. Average fruit size and total soluble solids of pulp were significantly influenced by N nutrition during the tenth year but other fruit quality attributes were unaffected by the nutrient levels when applied along with common dose of 8.6 g P and 58.1 g K/tree/year of age. Nitrogen at 50g/tree/year of age resulted in the best canopy development while at 100g/tree/year of age gave maximum fruit yield and was economical to apply. Tree growth and yield were very poor when N was not applied and also with very high N doses. P application was economical only at higher doses while K application did not reveal any beneficial effect for the young trees of 'Totapuri' mango.
