Effect of multimicronutrient on fruit yield of aonla (Emblica officinalis Gaertn.) Cv. Gujarat aonla-1

Abstract

The research experiment was carried out on “Effect of multimicronutrient on fruit yield of aonla (Emblica officinalis Gaertn.) Cv. Gujarat Aonla-1” at Horticultural Research Farm, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand during Kharif-Rabi season of the year 2017-18. The experiment was laid out in Completely Randomized Design with factorial concept (FCRD). There were three levels of soil application viz., S1 - Control, S2 - 250 g/tree multimicronutrient (Grade-V) and S3 - 500 g/tree multimicronutrient (Grade-V) and three levels of foliar application viz., F1-Control, F2-1 % Spray of multimicronutrient (Grade-IV) and F3 - 2 % Spray of multimicronutrient (Grade-IV). Soil application of multimicronutrient (Grade-V) was done at onset of monsoon and multimicronutrient (Grade-IV) was foliar sprayed at pin head and pea stage. Among all the treatments, F2 (1 % spray of multimicronutrient Grade-IV) treatment recorded significantly maximum number of fruit set per branch, number of fruit retention per branch, fruit length, fruit diameter, fruit weight, fruit volume, number of fruits per tree, A grade fruit yield, B grade fruit yield, C grade fruit yield and total fruit yield whereas, there was significant effect of soil application of multi micronutrient (Grade-V) on total yield. Among all the treatments, S3 (500 g/tree multimicronutrient Grade-V) was obtained significantly maximum total fruit yield.
