Effect of Organic (Crude) Antitranspirants on the Yield and Physiological Characteristics of Wheat (Triticum aestivum L.) Grown under Water Stress Conditions

The experiment was carried out with wheat (Triticum aestivum L.) in the winter of the 2024-2025 growing season in Babylon Governorate, the Al-Mahannawiyah region. The demonstration farm was used. The purpose was to enhance the water resistance capacity of the wheat plant and enhance the efficiency of the crop in terms of the irrigation security through gelatin as the raw organic material and foliar sprays on the crops at various concentrations (0.5%, 1%, and 1.5%), as well as a control group (0%). The effect of various levels of available soil water depletion (40, 60 and 80 percent) was also tested on the growth and productivity of crops. The optimal level of depletion gave the optimal harvest but at the same time resulted in the maximization of the irrigation efficiency and the release of water to more cultivated lands. This was done through a three section split-plot design. The findings proved that there was a negative correlation between growth indicators and the level of water depletion. A rise in the depletion of water was followed by a decline in most of the vegetative and productive characteristics, but not the profitability and water use efficiency of plants. This is seen by the fact that superior depletion of water was 60 and 80 percent as compared to the marginal depletion within the 40 percent treatment. Although the growth in the 60 percent and the 80 percent treatments was lower, they led to saving of the irrigation water in the area of 0.33 and 0.45 hectares, respectively. Use of antitranspirants was an important factor in reducing the impact of water stress. The growth indicators and yield growth is clear when gelatin is sprayed at 1% and 1.5% because the role of gelatin is realized. The outcomes of the research point to the conclusion that organic antitranspirants (crude gelatin) can help mitigate the adverse impacts of water stress on vegetative and fruit traits, as well as enhance plant productivity in using the available water resources and sparing the use of irrigation water to other areas of land.
