Abstract : The present trial was undertaken to assess the response of two levels each of Urea (1 and 2 per cent), Zinc Sulphate (0.5 and 1.0 per cent) and Borax (0.5 and 0.8 per cent) alone or in combination through foliar sprays on physico-chemical composition of Amrapali mango. The maximum size of fruit was obtained under Urea 2 per cent in combination with Zinc Sulphate 0.5 per cent, however maximum weight of fruit was recorded with Urea 2 per cent in combination with either Zinc Sulphate 0.5 per cent or Borax 0.8 per cent. On an average Urea 1 per cent proved itself to be the best treatment in reducing the stone of fruit. The spray of Urea 2 per cent in combination with ZnSO4 05 per cent caused maximum percentage of fruit pulp. The chemical composition of fruits such as T.S.S., acidity, sugar and ascorbic acid contents of fruits were greatly affected by the application of Urea and micro-nutrients. Maximum T.S.S., Total sugar percentage and reducing sugar were recorded with the spray of Urea 2 per cent along with ZnSO4 1 per cent. However maximum T.S.S./Acid ratio was obtained with Urea 2 per cent+ZnSO4 0.5 per cent.
