Effect of biofertilizers, GA3 and micronutrients on physiochemical characteristics of sapota cv. Kalipatti

A field experiment was conducted to study the response of biofertilizers (Azospirillum and PSB), GA3 and micronutrient mixture grade 4 on physio-chemical characteristics of sapota trees at FRS, Gandevi (Navsari Agricultural University, Navsari). The results revealed that the application of 100 or 75% RDF along with foliar spray of 50 ppm GA3 resulted in maximum fruit firmness, pulp-peel ratio, TSS, acidity and ascorbic acid content with minimum no. of seeds per fruit. Whereas, delayed ripening and maximum shelf life was recorded with the application of 75% RDF + Biofertilizers (Azospirillum + PSB) @ 40 ml/ tree + GA3 @ 50 ppm + micronutrient mixture Grade 4 @ 0.5%.
