Impact of foliar application of growth regulators and micronutrients on fruit yield and quality of Kinnow

Abstract

A research trial was carried out in a randomized block design with three replicates at Village Achariki, Abohar, District Fazilka, Punjab during 2017-2018 to study the effect of foliar application of growth regulators and micronutrients on yield and fruit quality of Kinnow. The experiment included nine treatments viz. Control (water spray), NAA@100 ppm, NAA@150 ppm, GA3@75 ppm, GA3@100 ppm, [email protected]%, [email protected]%, [email protected]% and [email protected]%. The application of GA3@100 ppm recorded the highest plant growth (plant height, stem girth, canopy volume (E-W/N-S) and leaf area), number of fruits per tree (458) and fresh fruit yield (114.0 kg per tree). Thus, it can be concluded that the selection of a suitable plant growth regulator or nutrient (macro or micro) for foliar application to a citrus fruit crop is of great importance in order to achieve highest yield potential and quality through the optimal growth.
