Abstract:
Drought stress is a key constraint on agricultural production in arid and semi-arid climates, reducing plant growth, yield, and nutrient absorption. Arbuscular mycorrhizal fungi (AMF) help to mitigate drought stress by increasing plant water and nutrient uptake, improving soil structure, and modifying plant physiological responses. The purpose of this study was to see how root colonization by Glomus mosseae and Glomus hoi affected sunflower (Helianthus annuus L.) growth, nutrient absorption, yield, and irrigation water productivity under different levels of drought stress. Drought stress was created by irrigation after 60% and 80% water depletion (mild and severe drought stress, respectively), with 40% depletion acting as a control. The results showed that mycorrhizal inoculation greatly increased plant biomass, root development, seed weight, yield, and nutrient absorption. G. mosseae outperformed G. hoi, with better seed output and nitrogen and phosphorus absorption. The presence of AMF significantly increased water efficiency and oil content. These findings are consistent with recent research on the role of AMF in drought resistance and nitrogen uptake in crops. The work emphasizes the significance of AMF in sustainable agriculture, particularly in water-stressed regions, and proposes that G. mosseae might be an important bio-inoculant for increasing sunflower production under drought stress circumstances.
