This study found that bean inoculation with Rhizobium alone or in combination with P application, can increase grain yield of the two common bean cultivars. This indicates that recommending these agronomic inputs for use by resource-poor farmers in Ethiopia will be very helpful to increase the local common bean yield. Compared with the Ibbado, Hawassa Dume has a higher yield. Therefore, Hawassa Dume could be recommended for adoption by farmers in combination with the Rhizobium inoculant strain HB-429 and P at 20 kg·ha⁻¹ P in Ethiopia.

The amount of nitrogen fertilizer needed to maximize the profitability of corn production in the Midwest has been increasing by about 1.2% per year for the past three decades, a trend driven by higher yields and wetter springs, according to new Iowa State University study.

This study elucidated that PDMA forms a tight and stable microbial network in the rhizosphere and promotes the mutual communication among microorganisms.
