abstract
The present investigation entitled “Effect of micro nutrient on yield and quality of Aonla (Emblica officinallis Gaertn L.) cv. NA-7” was carried out at the Horticulture Research Center, Department of Horticulture, HNB Garhwal University, Srinagar, Garhwal, Uttarakhand during the year 2013-2014. The experiment was conducted in Randomized Block Design with eight treatments and replicated in four times, considering one plant as a unit. The observations were recorded for Physico-chemicals and yield attributing characters of aonla fruits. The maximum fruit size, weight, volume and pulp: stone ratio was recorded with foliar application of Zinc sulphate, Magnesium sulphate and Copper sulphate (0.5 per cent each). Better quality fruits with respect to highest total soluble solids, sugars, ascorbic acid and low acidity percentage were recorded with combined spray of Zinc sulphate, Magnesium sulphate and Copper sulphate (0.5 per cent each). The fruit yield was also recorded maximum with the combined spray of Zinc sulphate, Magnesium sulphate and Copper sulphate (0.5 per cent each). Overall it can be concluded that combined application of Zinc sulphate, Magnesium sulphate and Copper sulphate (0.5 per cent each) judged the best for higher fruit yield, production and better fruit quality of aonla.
