The snap bean (Phaseolus vulgaris L.) is an economically important vegetable in Brazil. Bean plants can establish symbiotic associations with bacteria that fix atmospheric nitrogen. These associations show specificity of host plants to certain bacteria. Nitrogen fertilization constitutes a crop production cost, and the use of Rhizobium inoculation to supply nitrogen to crops may decrease the production costs. The aim of this study was to evaluate the effects of inoculation of three different snap bean cultivars with three Rhizobium tropici strains on agronomical performance of the plant. A completely randomized experimental design was used, with a 3 ? 5 factorial scheme and four replicates per treatment. The factors tested were three snap bean cultivars (UEL 1, Alessa, and UEL 2), and five types of inoculation (uninoculated control, inoculation with SEMIA 4077, SEMIA 4080, SEMIA 4088, or with a mix of the three strains). The experiment was conducted in a greenhouse. Plant height, stem diameter, pod length, the number of pods per plant, and average weight and yield of commercial-grade pods, were determined. An analysis of variance was conducted using the F test, followed by Tukey’s test (p < 0.05). Inoculation had a positive effect on all the parameters quantified. The beneficial effect was more pronounced in plants inoculated with the mix of Rhizobium strains.Metrics
