Research suggests that certain substances can improve drought resilience in various crops. Studies have investigated the effects of compounds such as abscisic acid, salicylic acid, and phytomelatonin on drought tolerance in plants like wheat, rapeseed, and maize. The use of these substances, as well as other methods like microbial biostimulants and organic amendments, may enhance growth, physiological performance, and yield in crops under drought stress conditions.
