Effect of micronutrients and banana pseudostem sap at different ph levels of foliar spray solution on fruit quality of mango (Mangifera indica L.) cv. Kesar

Abstract

The present experiment was conducted during 2015-16 and 2016-17 at RHRS, ACHF, NAU, Navsari, (Gujarat). The experiment was laid out in Randomized Block Design with Factorial Concept comprising two factors viz., different pH levels of foliar spray solution (4.5, 5.5 pH and best available water) and banana pseudostem sap (5%), novel organic liquid fertilizer (1 and 2%), mixture Grade IV (1%), boric acid (0.2%). The treatments were replicated thrice. The individual effects of foliar applications at induction of flowering and full bloom stage and their interactions on fruit quality characters of mango cv. Kesar were recorded. The results revealed that individual effects of different pH levels of spray solution and micronutrients and banana pseudostem sap found significant. The foliar spray solution at pH 4.5 level and foliar application of 2% novel organic liquid fertilizer gave maximum organoleptic evaluation score, TSS, total sugars, reducing sugars, non-reducing sugars, ascorbic acid content, shelf life and lower acidity.
