Effect of foliar application of liquid fertilizers and micronutrients on fruit quality and shelf life of Aonla (Emblica Officinalis)

Abstract

The result showed that the application of higher concentration (10%) of NPK liquid fertilizer gave the better result in terms of length of fruit (32.50 mm), diameter of fruit (41.62 mm), T.S.S. (14.58 0B), Vitamin-C content (565.68 mg/100gm of pulp) with minimum acidity percentage (1.98 %) and longest shelf life of aonla fruit. Among the different levels of micronutrients, application of micronutrients @ of 5% gave the better results in cash of length of fruit (31.46 mm) and diameter of fruit (40.09 mm), highest total soluble solid (13.57 0B), highest Vitamin-C (mg/100g of pulp), i.e.563.37 mg, lowest acidity (2.08%) with maximum shelf life (5.25 days) which was at par with micronutrients application @ 7.5%. Among the combinations of liquid fertilizers and micronutrients, the combination effect of NPK3 (10%) & MN1 (5%) gave the better quality and long shelf life. From the foregoing discussion it can be concluded that higher concentration (10%) of NPK liquid fertilizer and Micronutrient mixture (5%) found effective for better fruit quality and long shelf life.
