Nitrogen fertilization, inoculation and coinoculation in bean. The present work had as objective to evaluate the response of the bean to the inoculation, coinoculation and the nitrogen fertilization in the growth, production of pods and grains of the common bean. The experiment was conducted in a randomized block design with three treatments and seven replications. The treatments were defined as: (1) Control, without any seed treatment, with nitrogen fertilization at planting and cover; (2) Inoculation with Rhizobium tropici and nitrogen cover fertilization and; (3) Coinoculation with Rhizobium tropici and Azospirillum brasilense and nitrogen cover fertilization. The treatment of common bean seeds with inoculants resulted in productive parameters equivalent to common bean fertilized with mineral nitrogen fertilizer. In this way, inoculation and coinoculation can replace nitrogen fertilizer in the initial phase of the crop without prejudice to the number of pods per plant, number of grains per pod and weight of a thousand grains.
