The major problem associated with Aonla (Emblica officinalis Gaertn.), a minor fruit crop, suitable for rain-fed horticulture, having potential medicinal properties due to which it has become a most sought after fruit for ayurvedic preparations, is the reduced yield and quality due to many reasons. In this context, an investigation was taken up at College of Horticulture Bengaluru, to exploit the possibility of improving the fruit yield and enhancing the fruit quality through foliar application of micronutrients in aonla cultivar NA-7. The study revealed that the foliar spray of micronutrient combination of 0.5 % ZnSO4 + 0.5 % FeSO4 + 0.25 % Borax) significantly increased yield (6.93 tonnes/ha). The yield was almost double as compared to control in the said combination of micronutrients as result higher benefit cost ratio (3.60) was recorded. Further, the quality parameters of fruits such as higher total sugar, reducing sugar and non-reducing sugar content of fruits was significantly improved without reducing the vitamin C (483.71 mg/100 g) with the above said combination of nutrients. Hence, the micronutrient combination of 0.5 % ZnSO4 + 0.5 % FeSO4 + 0.2 5% Borax holds immense potential as a foliar spray in arresting fruit drop and doubling up the yield in aonla under rain-fed conditions of southern dry zone of Karnataka.
