Abstract : A field trial was conducted during 1985-95 to assess the nutritional requirement of Totapuri mango under rainfed conditions at Bangalore. Results suggested that N application significantly influenced the tree growth and fruit yield of young Totapuri trees 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. N at 50 g/tree/year of age resulted in the best canopy development while N at 100 g/tree/year of age gave maximum fruit yield. Tree growth and yield were very poor when N was not applied and also with very high N rates. P application was economic only at higher rates while K application did not have any beneficial effect on young trees.
