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 requir ement. 'Totapuri' mango (Mangifera indica) under rainfed condition at Bangl ore. Results of a this field trial suggested that, N application significan tly influenced the tree growth and fruit yield of young 'Totapuri' trees un der rainfed conditions while P and K application did not. Average fruit siz e and total soluble solids of pulp were significantly influenced by N nutri tion during the tenth year but other fruit quality attributes were unaffect ed by the nutrient levels when applied along with common dose of 8.6 g P an d 58.1 g K/tree/year of age. Nitrogen at 50g/tree/year of age resulted in t he best canopy development while at 100g/tree/year of age gave maximum frui t yield and was economical to apply. Tree growth and yield were very poor w hen N was not applied and also with very high N doses. P application was ec onomical only at higher doses while K application did not reveal any benefi cial effect for the young trees of 'Totapuri' mango.
