- Abstract
N2-fixing bacteria symbiotically dwell inside the root nodules of legume and converts atmospheric N2 to NH3. Unlike high temperature–pressure Haber's process, this conversion in the nodule is orchestrated by nitrogenase: an enzyme with Fe-S, Fe-Mo, Fe-V cofactor, at its heart. Strategies to increase the nodule population could reduce nitrogen fertilizer use. Here we discovered that pre-treating the chickpea seeds with nano FeS2 (iron pyrite) resulted in a denser root network with larger root nodules. It improved the shoot system and resulted in a higher yield. We observed a higher concentration of Fe, Mo, Mg, P, Ca, Mn, K in the roots of chickpea: possibly emulating nitrogenase.
