A field experiment was conducted to investigate the Rhizobium-legume symbiosis effectiveness. Four commercial common bean cultivars (Canario Centenario, Canario CIFAC, Blanco Molinero and Rojo Molinero) were studied in order to characterize the cultivars' variability in symbiotic characters using two Rhizobium sp. strains (LMT 10 and LMT15) and the indigenous soil strain, and an Nfertilization rate. As indicators of effectiveness, the variables were grouped into three classes. Days to flowering, height, fresh and dry's foliage weight, fresh and dry's roots weight were taken as the morpho-physiological variables. Number, position, size, shape, inner colour, fresh and dry's nodules weight were taken as the variables of nodulation. Pods number per plant, seed number per pod, 100 seed weight, harvest index, dry bean yield were taken as the variables of plant yield. ANOVA indicates that there are significant differences among varieties, but no in nitrogen sources, indicating that the inoculated strains had the same effectiveness as the native soil strains and N-fertilization. The varieties with the highest yields were Canario Centenario with N-fertilization (3062.19 kg.ha-1), Blanco Molinero with indigenous soil strain (2835.57 kg.ha-1) and Blanco Molinero with LMT 10 strain (2815.11 kg.ha-1). A significant interaction of bean variety x nitrogen source was found for pods number per plant (p <0.05) and harvest index (p <0.01), where the best treatment was Canario Centenario with N-fertilization, 21.44 pods per plant and 64.97% respectively. Blocks did not show highly significant statistical differences. Among varieties, Canario CIFAC had the best performance for morpho-physiological variables, Blanco Molinero for the nodulation and Canario Centenario for yield variables. Among the nitrogen sources, LMT 10 strain was the best performance for morpho-physiological variables, LMT 15 strain for the nodulation and yield variables, although the native strain obtained the highest values in number and fresh weight of nodules, dry bean yield, which describes the competitiveness with regard to inoculated strains.
