An investigation was carried out on 15 years old plantation of Aonla (Emblica officinalis Gaertn.) cv. Chakaiya at Kumarganj, Faizabad (Uttar Pradesh) during the year 2013-14. In all, 8 treatments of foliar nutrients application viz. control (water spray), K2SO4 (2%), KCL (2%), KNO3 (2%), K2SO4 (2%) + urea (2%), KCL (2%) + urea (2%), KNO3 (2%) + urea (2%) and urea alone (2%) were tasted in RBD replicated thrice. On total 24 trees of Aonla, manures and fertilizers were applied as per recommended schedule for aonla plantation. The treatments were applied twice i.e. after fruit set and at fruit bud development stages. The results obtained revealed that the treatment foliar application of H2SO4 + urea recorded minimum percent fruit drop, maximum per cent fruit retention, biggest fruit size, highest fruit weight, maximum pulp: stone ratio and TSS content in pulp, minimum acidity content, maximum vitamin ‘C’ content and percentage of total sugars and significantly highest fruit yield per tree among all treatments tried. It was followed by the treatment foliar application of KCL + urea in all fruit characters including yield. Lone spraying of K2SO4, KCL or KNO3 could not prove significant superiority over control in most of the cases while urea alone spray was found significantly superior over control in almost all observations including fruit yield.

Keywords: Aonla, Foliar spray of nutrients, Potassium sources, Urea, Yield, Quality.
