The Role of Plant Growth Regulators in Enhancing Nutrient Uptake Efficiency in Bitter Gourd (Momordica charantia L.)

The present investigation was undertaken to find out the suitable plant growth regulators with appropriate doses for increasing the fruit yield potential of bitter gourd. Plant growth regulators in very minute quantities can dramatically induce the responses mentioned above. The response to PGR, however, varies with the cultivar, age of the plant, light, temperature, availability of mineral nutrients, vigour of the plant and its endogenous hormonal content. The present experiment was conducted at Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during the session 2022 - 2024. The experiment was laid out in randomized block design with three replications, and the study consists of thirteen treatment combinations including control. The best treatment was T12 (NAA200ppm) which shows highest values in highest total nitrogen uptake (35.11 kg ha-1), total phosphorus uptake (5.78 kg ha-1), total potassium uptake (13.89 kg ha-1).
