- Abstract
Water stress affects the growth, development, and yield of crops. The objective of this study is to evaluate the positive effects of nutrients (calcium, potassium, and boron) on durum wheat facing drought stress. Two treatments of calcium, potassium, and boron were used under drought and well-watered conditions on two varieties of durum wheat (V1—Preco; V2—Kronos). The data depict that the exogenous application of these nutrients gave significantly different (p < 0.05) results. The percentage increase in shoot length and root length was 29% and 35% compared to the untreated, drought-facing plants. There is also an increase in the synthesis of photosynthetic pigments and osmolytes. The foliar spray of nutrients enhances the synthesis of antioxidants, including superoxide dismutase, catalase, and peroxidase, which reduce the production of free radicals. It also helps to maintain the stability of membranes and other cell organelles. The spray application enhances the yield of durum wheat, i.e., the percentage increase in the number of grains per spike and 1000-grain weight was 23% and 25% compared to the untreated, drought-facing plants. The use of these nutrients considerably improves the functioning of antioxidant machinery, helping combat the adverse effects of drought. Additionally, they improve the growth- and yield-related parameters. Hence, these sprays can be used as a plant growth regulator.
