Abstract
Common bean (Phaseolus vulgaris L.) is one of the most important and widely cultivated pulse crops in most developing countries. However, its cultivation is globally constrained mainly by low soil fertility and lack of improved agronomic practices. A field experiment was conducted at Hawassa University College of Agriculture, Hawassa Southern Ethiopia to determine the effect of N fertilization and Rhizobium phaseoli strain HB-429 inoculation on growth, nodulation, yield and yield components of common bean variety Hawassa Dume. The experiment was laid out as a randomized complete block design with three replications. Results showed significant increase in growth, nodulation, yield and yield components in plants inoculated with Rhizobium strain HB-429 over the control. Thus, from the results of this study, it can be concluded that Rhizobium inoculation with strain HB-429 is the best performing treatment to be recommended for profitable grain yield of common bean at the Hawassa and other similar areas.
Key words: Common bean, grain yield, nitrogen, nodulation, Rhizobium inoculation
