Abstract

The investigation was conducted at the Research Farm of the Division of Fruit Science, SKUAST-Kashmir, Shalimar campus, during 2016 and 2017 to evaluate the effects of chemical thinning agents on vegetative growth, fruit set, yield, and fruit quality of the nectarine cultivar 'Silver King.' The chemicals tested, were Naphthalene Acetic Acid (NAA), Urea, and Ethephon and were applied after petal fall. The findings revealed that NAA (30 ppm) significantly enhanced vegetative parameters such as plant height, shoot elongation, and leaf area. Both NAA and ethephon effectively reduced fruit set and overall yield while improving fruit quality traits, including fruit size, weight, and coloration. Additionally, ethephon (150 ppm) accelerated fruit maturation by 7–8 days. These results indicate that chemical thinning, particularly with NAA and ethephon, holds potential for optimizing fruit quality and marketability in the 'Silver King' nectarine cultivar.
