The experiment was carried out on mango (Mangifera indica L). cv. Dashehari to investigate the effect of foliar spray of micronutrients and sorbitol on fruit set, yield and fruit quality parameter. Seven treatments comprising of calcium nitrate (0.06%), boric acid (0.02%), sorbitol (2.0%) alone & in combinations (Le. calcium nitrate @ 0.06% + boric acid @ 0.02%, calcium nitrate @ 0.06% + sorbitol @ 2.0% and boric acid @ 0.02% + sorbitol @ 2.0%) and control (water spray) were used as foliar spray solutions at the time of start of flowering. The experiment was laid out in a Randomized Block Design (RBD) with four replications and two trees under each replication. Data were recorded on percentfruit set, yield and quality parameters offruits. The data were statistically evaluated by using standard procedures. The pooled data for the year 2009 and 2010 indicated that the foliar treatments with micronutrients and sorbitol were found very effective for increased fruit set, yield and fruit quality. The boric acid (0.02%) with sorbitol (2.0%) proved to be most effective for enhancing fruit set (1.58%), yield (48.51 kg tree^-1), fruit weight (165.6 g), TSS content (18.59°B), total sugar (14.92%), ascorbic acid (20.32 mg 100 g⁻¹) and pcarotene (3.01 mg 100g⁻¹).
