The present investigation entitled on Effect of nutrients on yield and chemical characteristics of aonla (Emblica officinalis Gaertn) cv. Chakiya was carried out at Department of Horticulture and Post-Harvest technology, Institute of Agriculture, Visva-Bharati, Sriniketan, West Bengal during the year 2016-17. The experiment was conducted over 27 trees which are Planted at spacing of 10m×10m having nine treatments consisting of various level of nutrients concentration [T1 – Borax @0.25%, T2– Borax @0.50%, T3 – ZnSO4 @0.40%, T4 – ZnSO4 @0.60%, T5 – Borax @0.25%+ ZnSO4 @0.40%, T6 – Borax @0.25%+ ZnSO4 @0.60%, T7 – Borax @0.50%+ ZnSO4 @0.40%, T8 – Borax @0.50% + ZnSO4 @0.60%, T9 – Control (water spray)] in RBD design with 3 replications. Foliar application of Borax (0.25% and 0.50%), ZnSO4 (0.40% and 0.60%) and their combination were sprayed during the flowering and pea stage of the fruits. Among different dose of nutrient treatments, T8- Borax @0.50%+ Zinc @0.60% were found significantly superior over other treatments with respect to fruit yield, acidity, ascorbic acid, total sugar, TSS and reducing sugar of the fruit.
