ENHANCING ASH GOURD GROWTH AND YIELD WITH GA₃ AND BORON APPLICATION

Abstract

Ash gourd (Cucurbita moschata) is valued for its nutritional and commercial benefits, especially in regions with limited year-round vegetable availability like Pakistan. This study evaluated the effects of gibberellic acid (GA₃) and boron on ash gourd growth and yield using a randomized complete block design at Ghazi University, Dera Ghazi Khan (Nov 2022–Mar 2023). GA₃ significantly enhanced vegetative growth by increasing vine length, leaf number, and fruit size, while boron improved flowering, fruit set, and development. Combined application of GA₃ and boron boosted fruit number, weight, and overall yield compared to controls. Results varied by genotype and application method, indicating the need for further research to optimize rates and timing. Integrating GA₃ and boron shows promise for improving ash gourd productivity and profitability.
