Effect of Exogenous Plant Growth Regulators on Growth, Yield, and Quality of Parthenocarpic Cucumber/English Cucumber (Cucumis sativus L.) under Protected Condition

Abstract

This study was carried out during the Rabi season 2022-2023 to investigate the effect of different levels of NAA, GA3, and TIBA on the growth, yield, and quality of Pusa Parthenocarpic cucumber – 6 and to estimate the economics. The study was conducted from January to March 2023, the research revealed NAA's significant effect on vine length, earliness parameters, yield, and quality attributes. Treatment 8 (NAA@200ppm) emerged as particularly promising, demonstrating superior growth with an average plant height of 290 cm, accelerated development with an average fruit weight of 252.67 g, and a maximum benefit-cost ratio of 2.39.
