Abstract:
The study aimed to assess the effects of foliar spray using different phytohormones, such as salicylic acid and brassinolides, on various plant growth and yield parameters of maize. The experiments were conducted on COH(M) 8 maize seeds to identify suitable phytohormones and optimize their concentrations for improving its yield under drought-stress conditions. Foliar spray treatments involved different concentrations of salicylic acid (50, 75 ppm) and brassinolides (0.2, and 0.5 ppm) along with a control group. The findings indicated that seeds treated with salicylic acid at a concentration of 75 ppm exhibited better performance outperforming the control and other treatments, regardless of the drought stress conditions.
