Yield and yield attributing characters influenced by foliar spray of micronutrients and banana pseudostem sap at different pH levels of on mango 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 yield and yield attributing characters of mango cv. Kesar were recorded. The results revealed that the foliar spray solution at pH 4.5 level and foliar application of 2% novel organic liquid fertilizer gave maximum yield viz., number of fruits/panicle, numbers of fruits/tree and fruit yield (kg/tree and t/ha) and yield attributing characters like, fruit weight (g), fruit length (cm), fruit breadth (cm), fruit volume (cm3), specific gravity (g/cm3), firmness of fruit (kg/cm2), pulp: stone ratio and minimum peel percentage. Interaction of different pH levels with banana pseudostem sap and micronutrients was found significant in case of number of fruits per panicle, fruit yield kg/tree and fruit yield t/ha of mango during investigation, which were the maximum when mango cv. Kesar tree treated at induction of flowering and full bloom stage with 2% novel organic liquid fertilizer at 4.5 pH level.
