 ABSTRACT

The present study was conducted at a full bearing orchard of apple at Wathoo, Shopian near KVK Balpora, Jammu and Kashmir, India. The present study aimed to investigate the effect of calcium and potassium application on growth, yield and quality of apple cv. Red Delicious during the year 2019. The results reviled that maximum annual shoot growth, total soluble solids, TSS:acid ratio, total and reducing sugars and minimum acidity were observed in T7 (Calcium nitrate @ 500 gram/tree + Potassium sulphate @ 2.5 gram/litre). However, the maximum chlorophyll content, fruit physical parameters viz., fruit diameter, fruit length, weight, yield, volume and specific gravity were found in treatment T6 (Calcium nitrate @ 500 gram/tree + Calcium chloride @ 2 gram/litre). However, the maximum fruit firmness and ascorbic acid was observed in treatment T3 (Calcium chloride @ 500 gram/tree) and the minimum physiological loss in weight has been recorded under treatment T8 (Calcium chloride @ 500 gram/tree + Calcium chloride @ 2 gram/litre) as compared to other treatments and control. The overall results indicated that calcium nitrate significantly influenced vegetative growth, chlorophyll content of leaf and fruit physical and Chemical parameters, However the highest ascorbic acid and lowest physiological loss in weight recorded by calcium chloride treatments.
