Effect of soil application of micronutrients on Mangifera indica

Abstract

This study was conducted on Mangifera indicaMangifera indica. The trees were 10 years old, budded on Mangifera indica rootstock and grown on calcareous soil in a private orchard located at Udai College, Varanasi, india. Thirty trees as uniform a possible were selected for this study. The trees were at 5.5 x 5.5 m. apart. The experiment involved the following ten treatments: Control, 0.60 g Micronutrients + 0.4 ml P/L at full bloom, 0.80 g Micronutrients + 0.4 ml P/L at full bloom, 1.10 g Micronutrients + 0.4 ml P/L at full bloom, 0.60 g Micronutrients + 0.4 ml P/L at fruit set, 0.80 g Micronutrients + 0.4 ml P/L at fruit set, 1.10 g Micronutrients + 0.4 ml P/L at fruit set, 0.60 g Micronutrients + 0.4 ml P/L at full bloom + fruit set, 0.80 g Micronutrients + 0.4 ml P/L at full bloom + fruit set and 1.00g Micronutrients + 0.4 ml P/L at full bloom + fruit set. The results show that spray with 1.00g Micronutrients + 0.4 ml P/L at full bloom + fruit set gave the best results in comparison with control. This treatment gave the highest values of leaf and fruit mineral content, improved all vegetative growth parameters and chlorophyll content of leaves, and improved the physical and chemical characteristics of fruits.
