Effect of Soil and Foliar Applications of Micronutrients on Flowering and Yield of Mango

Abstract

The experiment was carried out during the spring and summer seasons of the year 2017-18 and 2018-19 at the Horticultural Research Farm, AAU, Anand to study the “Effect of soil and foliar applications of micronutrients on flowering and yield of mango variety”. The experimentcomprised of 13 treatments of different micronutrients application viz. FeSO4 100 g, ZnSO4 100 g, Borax 100 g and multimicronutrients grade-V 400 g as a soil application; FeSO4 0.5 %, ZnSO4 0.5 %, borax 0.2 % and multimicronutrients grade-IV 1.0 % as a foliar application and its combinassions and control (water spray). Soil application was done at second fortnight of September and foliar sprays of treatments were done at flower bud initiation, full bloom stage and pea stage initiationon 18 years old mango tree cv. Mallika. Experiment was laid out in a Completely Randomized Design (CRD) with three repetitions. Numbers of staminate, hermaphrodite and total number of flowers per panicle were found significant with respect to various micronutrients treatments during both the years of experiment. Maximum staminate flowers per panicle, hermaphrodite flowers per panicle and total number of flowers per panicle was found with soil application of multimicronutrients grade-V 400 g followed by foliar application of multimicronutrients grade-IV 1.0 % during both the years of study. The significantly higher number of fruits, average fruit weight and fruit yield per tree were recorded with soil application of multimicronutrients grade-V 400 g followed by foliar application of multimicronutrients grade-IV 1.0 % during the years 2017-18 and 2018-19.
