Study of Biostimulants, and Their Effects on Crop Production

Biostimulants are one of the most important methods for improve productivity, growth and yield of plants as well as heavy metal detoxification, stimulate natural toxins, controlling pests and diseases and boost both water and nutrient efficiency. Amino acid has several benefits such increase nutrient assimilation, increase yield and yield components as well as increase photosynthesis processes and promote stress tolerance. Phenols may regulate and improve photosynthesis, oxidation-reduction process, physiological activities of plants, reduce the adverse impacts of toxic compounds, and improve anti-fungal activities of plants. Salicylic acid may have important roles in abiotic stresses such salinity, drought, cold, heavy metal and heat stresses, and it has been considered as an important environmentally-sound agent with tremendous economical benefits and rapid responses.
