Additive effect of AM Fungus and Rhizobium with Molybdenum sources on Growth and Nutrient Content of Tamarindus indica L.

This study investigated the synergistic effects of Arbuscular mycorrhizal (AM) fungi, Rhizobium bacteria and molybdenum on Tamarindus indica L. seedling growth and development. Dual inoculation with AM fungus Rhizophagus fasciculatus and Rhizobium combined with molybdenum treatment significantly enhanced plant growth parameters, nutrient uptake and overall plant health. Key findings include increased shoot and root length, leaf length and leaf number, enhanced mycorrhizal colonization and root nodulation and improved uptake of essential nutrients (N, P, K, Mg and Mo) in plants receiving combined treatment. The results suggest that this approach could reduce the need for inorganic fertilizers, promoting more sustainable agricultural practices. The study highlights the importance of understanding complex interactions between beneficial microorganisms and micronutrients in plant growth. Combined application of AM fungi, Rhizobium and molybdenum could be an effective strategy for improving Tamarindus indica L. cultivation and potentially other leguminous plants. Future research should focus on optimizing application rates and methods in field conditions, investigating long-term effects on plant productivity and soil health and exploring this approach in different soil types and environmental conditions.
