Abstract

Molybdenum (Mo), known for its pivotal role in nitrogen fixation and other enzymatic processes in leguminous plants. A field experiment was conducted to investigate the influence of molybdenum (Mo), bacterial inoculants (Rhizobium and PSB), and NP fertilizers on broad bean grown at Wood House Farm in Ooty, Tamil Nadu, India. The study employed a Factorial Randomized Block Design with 16 treatments. Bacterial inoculants were prepared using lignite-based formulations, Mo was applied as sodium molybdate with 4 levels (0, 0.3, 0.4 and 0.5 mg Mo kg−1) and NP fertilizers were imposed in 2 levels, 100% NP and 75% NP. The results showed significant effects on plant height, the number of leaves per plant, and the time taken for 50% flowering. Bacterial inoculants, NP fertilizers, and Mo levels exhibited positive impacts on these growth parameters. The interaction between these factors also played a significant role, highlighting the synergistic effects of their combined application. This study enhances our understanding of nutrient management practices in agriculture, providing valuable insights for optimizing crop yields and sustainability.
