Growth Regulators and Cucumber Yield: A Study on Vegetative Development and Yield Dynamics (Cucumis sativus L.)

Bioregulators, commonly known as plant hormones, play a pivotal role in the development and productivity of crops. This study investigates the impact of various growth regulators on the vegetative and yield dynamics of cucumber (Cucumis sativus L.), a vital horticultural crop with significant economic and nutritional value. By examining the effects of specific growth regulators on cucumber plants, the research aims to enhance our understanding of how these substances influence growth patterns, flowering, fruit set and ultimately, yield. The findings have the potential to inform agricultural practices and optimize cucumber production, contributing to improved food security and sustainable farming practices. The experiment was carried out during summer season 2021 at Vegetable Research Farm, Institute of Agricultural Sciences, Banaras Hindu University. The trial was accomplished in a randomized block design with three replications and 13 treatments. Plant growth hormones viz., GA3 (50, 100 and 150 ppm), NAA (25, 50 and75 ppm), AgNO3 (125, 250 and 350 ppm) and ethrel (100, 200 and 300 ppm) were applied as foliar spray at two true leaf stage. The findings of the effects of plant growth regulators on cucumber growth, presented in this abstract serve as a valuable resource for researchers, agronomists and farmers seeking to optimize cucumber cultivation practices and meet the increasing demand for this popular vegetable crop.
