Abstract

This experimental investigation examined the effects of gelatin concentrations on onion plants (Allium cepa L.) cv. Giza red seedlings under the influence of water stress over the course of two consecutive seasons (2022/2023–2023/2024). Thus, the purpose of this experimental study was to improve the growth process and yield parameters of onion plants in sandy loam soil conditions in the Belbeis region of El Sharkia Governorate, Egypt, by using different concentrations of gelatin (1.0, 1.5, and 2.0%) as well as the control under different levels of water supply (100, 75, and 50% of ETc, i.e., evapotranspiration). Four times was the gelatin foliar spraying procedure applied: once on December 7th, and then every 15 days using a backpack sprayer with a 20-liter capacity till the drop point. Data from this experimental study's two experimental seasons made it clear that, when compared to the control, every treatment greatly accelerated the growth process of the plants and yield characteristics. However, spraying with foliar spraying with gelatin (2%) under water supply of 100 or 75% of ETc achieved economic vegetative growth and yield.
