Effect of pruning intensity and foliar application of micro-nutrients on physical and chemical quality of aonla (Emblica officinalis Gaertn L.)

Abstract

A field experiment was conducted at Experimental Unit, Department of Horticulture, Post Graduate College, Ghazipur, Uttar Pradesh during the year 2021-23. Pruning of Aonla at 50% combined foliar spray with boron 0.4% increased number of fruits and fruit length, fruit width and fruit weight closely followed by ZnSO4 0.4% and CuSo4 0.4% with pruning at 50%. Better response was obtained with fruit yield attributing attributes also. The fruit quality in terms of TSS, acidity, ascorbic acid content and sugar content were also better with boron 0.4% combined with 50% pruning closely followed by ZnSO4 0.4% with 50%.
