HUMIC EXTRACT AS A BIOSTIMULANT IN CROPS SUBJECTED TO ABIOTIC STRESS

Because abiotic stresses pose significant challenges to the growth and productivity of crops, development plants with greater survival when exposed unfavorable situations is an objective several research groups. Biostimulants are substances or microorganisms that, applied crops through foliar root pathways, serve enhance various processes related development. These include nutrient absorption, tolerance environmental stress, overall harvest quality. Interestingly, biostimulants can achieve these effects even they possess a low concentration elements in their composition. Among main most often used plant hormones, algae extract, mycorrhizal fungi, protein hydrolysates, humic (humic fulvic acids). This review sheds light on biostimulant applying experiencing hydric stress conditions rainfed cultivation. Additionally, it aims identify gaps current highlights areas that require further investigation. Furthermore, provides concise overview origin progression (HS), including extraction obtaining process, as well structural characteristics relationship between structure, properties, functions. The also presents findings support potential influencing affected by stress. highlight beneficial enhancing resilience performance facing such drought, salinity, temperature extremes, other non-biological stressors. evidence underscores significance valuable tool mitigating detrimental impacts crop health.
