Abstract

The study investigates the effects of various chemical hybridizing agents (CHAs) on the morphological traits of Sponge gourd (Luffa cylindrica) over two growing seasons (2023-2024 and 2024-2025) at the Vegetable Research Centre, JNKVV, Jabalpur. The research primarily focuses on vine length, number of primary branches, internodal length, nodes per vine, and flower development stages. Statistical analysis of the collected data reveals that the application of CHAs significantly enhances vine length at 30, 60, and 90 days after transplanting (DAT), with the highest growth observed in treatments involving GA3 (200 ppm) and Sulphonyl Urea (0.4 ml/L). Notably, vine lengths reached up to 6.88 m at final harvest for the most effective treatments. Furthermore, the number of primary branches and nodes per vine also increased substantially with CHA application, particularly with GA3 and Sulphonyl Urea. The timing of flower appearance was influenced by these treatments as well, with earlier flowering noted in Ethrel-treated plants. The study concludes that strategic application of CHAs can significantly improve growth parameters and flowering dynamics in Sponge gourd cultivation, suggesting potential for enhanced yield and agricultural practices. This research contributes valuable insights for horticulturists aiming to optimize growth conditions for this economically important crop.
