Horticulture crop production facing several challenges particularly abiotic stresses and malnutrition resulting in yield loss and affects negatively fruit quality. The main effects of plant stimulants due to its working as the auxin-like effect, enhancing Nitrogen uptake, and stimulate plant growth. There is various stimulation effects on horticulture crops including promote plant growth, increase plant tolerance for biotic and abiotic. Applying plant stimulants to plants or the rhizosphere stimulating plant metabolic processes, increase the efficiency of the nutrients, and increase plant tolerance to abiotic stress, consequently, improving plant growth increases yield, and enhancing fruit quality.
