The present investigation was carried on seven year old plants of Apple cv. Gala Redlum grafted on M9-T337 rootstock at experimental farm, Division of fruit science, SKUAST-K, Shalimar. Foliar sprays with nutrients consisting of seven treatments T0 (control), T1 (Macarena@1.5ml/l), T2 (Plentigrow@4ml/l), T3 (Cytored@4ml/l), T4 (Macarena + Cytored@1.5+4 ml/l), T5 (Plentigrow + cytored@4 + 4 ml/l), T6 (Macarena + Plentigrow + Cytored@ 1.5 + 4 + 4 ml/l). The experiment was laid out in a randomized complete block design and replicated thrice. Foliar sprays of nutrients (Macarena and Plentigrow) were carried twice during the season at 50% bloom and one month after first spray and Cytored was sprayed at beginning of fruit color change (2nd week of July). Amongst nutrient sprays, (T6) combination of (Macarena + Plentigrow + Cytored@ 1.5 + 4 +4 ml/l) recorded highest yield attributes in terms of fruit set, retention and yield whereas fruit drop was minimum. The fruit attributes like fruit length, fruit diameter, L/D ratio, fruit weight, SSC and reducing sugars were maximum under combined application of (Macarena + Plentigrow + Cytored@ 1.5+4+4 ml/l) however titrable acidity and fruit firmness were less. The foliar application is the quick method due to which we get instant results because it get directly penetrated to the target sites where it is applied

CONCLUSIONS The best combination of foliar application of Macarena + Plentigrow + Cytored (T6) improved yield and quality parameters in Gala Redlum variety of apple. The main aim of farmer is to get the maximum yield and good quality fruit in order to fetch the maximum return from the market. So, the results confirm that foliar nutrient sprays can be useful tool for orchardists to get the quick response of plants in very less time as compared to other methods of fertilizers. Hence the combined foliar application of macro and micro nutrients are recommended to improve the yield and quality parameters of apple
