The present study was carried out in two successive years to evaluate the comparative efficacy of CPPU and NAA combination in improving the yield attributes of Langra mango. Higher fruit drop and low fruit retention are the most critical constraints for mango production under north Indian conditions. Fruit drop starts occurring just after fruit set and continues till harvest, leading to substantial economic loss to the growers. The foliar application of CPPU 10 ppm + NAA 20 ppm and CPPU 20 ppm + NAA 30 ppm immediately after the fruit set resulted in a significant reduction in fruit drop in comparison to the control (water spray). Various physical attributes like endocarp size (5.16 cm), pedicel length (1.20 cm), pedicel thickness (4.02 mm), fruit weight (248.12 g), fruit size (7.46 cm width and 9.83 cm length), fruit volume (243.52 cc), and specific gravity (1.02) got improved with CPPU 10 ppm + NAA 20 ppm followed by CPPU 20 ppm + NAA 30 ppm than the control. In conclusion, the spray of CPPU 10 ppm + NAA 20 ppm proved to be an effective treatment for managing fruit drop and improving yield attributes in Langra mango.Abstract
