Description
Eleven available strains of Bradyrhizobium sp were used to test four forage legumes, Crotalaria juncea (Crotalaria), Cajanus cajans (Guandu), Styzolobium deeriagianum (Mucuna-Ana) and Cyamopsis tetragonoloba (Guar) for symbiotic N-fixation ability. Greenhouse experiments were conducted for nine weeks in order to evaluate shoot, root, and nodule dry weight, nodule number, and shoot nitrogen content. Four strains presented relative nitrogen efficiency (RNE) over 100% with Crotalaria cultivar, whereas only one strain was more efficient with Guandu and Mucuna cultivars. Strain 633 was the only one which presented a high yield with Crotalaria, Guandu and Mucuna-Ana cultivars.
