Abstract:
The present study was conducted at AARC to determine the response of the Cytonutri CaB on the quality of apple (Malus × domestica Borkh) cv. Red Delicious. The study shows that the growth of apple fruit was significantly influenced by plant nutrition product. Among the different treatments maximum Bloom density of 183.44% was observed with T3. The data on flower drop revealed that significantly least flower drop of 19.67% was recorded with T3, whereas, significantly maximum flower drop was observed in untreated control plants. Maximum fruit set of 32.74% was recorded with treatment T3 which was followed by treatment T2 (29.24%) and T1 (28.43%), however, significantly low fruit set of 24.51% was obtained in control. The minimum fruit drop of 7.05% was observed in the treatment T₃ however, the fruit drop (9.92%) was comparatively more in control. Maximum fruit weight, breadth and yield was recorded with T3. All the chemical treatments had least fruit colour compared to control. It may be due to reduced senescence caused by calcium. The chemical sprays had significant effect on fruit firmness with 13.29, 13.12 lbs and 13.01 lbs values obtained in T2, maximum TSS of 14.87 ⁰B was observed with T2 followed by 14.87 ⁰B in T2 and 13.72 in T3 respectively. No phytotoxic symptoms were observed.
