Liquid Rhizobium inoculant formulations to enhance biological nitrogen fixation in food legumes

摘要

A liquid inoculant formulation was developed with higher shelf life of more than 540 days. Liquid Rhizobium inoculants (LRI) performed better than carrier based Rhizobium (CRI) inoculants in groundnut, soybean, chickpea and pigeonpea under field conditions. Nodule number per plant and grain yield were improved due to inoculation of liquid Rhizobium inoculants compared to carrier based Rhizobium inoculants in all tested crops.
