Seaweed Extract Biostimulants Differentially act in Mitigating Drought Stress on Faba Bean (Vicia faba L.)

Abstract Prolonged drought periods cause a cascade of biochemical alterations in plants and lead to reduction plant growth crop productivity. Seaweed extracts are category biostimulants that effective alleviating stress on plants. However, the effect seaweed attenuating negative impact Faba bean ( Vicia faba L .) under arid semi-arid conditions has received little attention. This study was conducted evaluate performances made from Fucus spiralis (FSE), Ulva lactuca (ULE), Laminaria ochroleuca (LOE), Ascophyllum nodosum (ANE) mitigating bean. The profile characterized, key physiological parameters were assessed during both recovery phases. All investigated positively affected biomass conditions. Plants LOE had higher relative water content lower malondialdehyde concentration comparison with stressed control positive ANE FSE mainly attributed proline accumulation tissues stress. ULE application resulted soluble sugars treated It concluded originating different sources extracted using protocols act differentially altering plant-related traits. Overall, potentially an solution manage scarcity
