Effect of integrated nutrient management on growth and yield of dragon fruit (Hylocereus polyrhizus Britton & Rose)

Abstract

An experiment was conducted to evaluate the effect of integrated nutrient management on growth and yield of dragon fruit. The experiment was carried out in Randomized Block Design with 11 treatments with three replications. The result on the effect of integrated nutrient management on plant growth parameters and yield and yield attributing parameters indicated that the treatment of 75% NPK + 2 kg vermicompost + 100 ml Azotobacter + 100 ml PSB + 100 ml KSB (T10) recorded maximum incremental stem length (62.33 cm), number of cladode (8.20), highest number of flowers per plant and per pillar (6.73 and 26.93, respetively), fruit set (91.33%), fruits per plant and per pillar (6.15 and 24.60, respetively), yield (2.25 kg/ plant), yield (9.01 kg/ pillar) and yield (10.41 t/ha), maximum average fruit length (12.33 cm), fruit breadth (8.97 cm) and fruit weight (406.17 g).
