The use of inoculants represents a cost savings to the country, in addition to this, there is a tendency towardworld agriculture to reduce the use of raw materials and energy, providing an improvement in environmental quality.Thus, the objective of this work was to identify promising genotypes when submitted to cropping systems with less useof nitrogen fertilization mineral and assess the effects of genotype x environment interaction in characters of agronomicinterest and cultivation system. Were evaluated 12 bean genotypes in different environments and two cropping systems(with urea and with inoculation). For the character number of nodules totals (NNT) genotypes SM0212, SH057, Perola,SH0413, SH061, SP12072, and SM1010 can be considered promising. The system of cultivation had an influence on theenvironment, this being more pronounced in Maquiné than in Santa Rosa. The increase in cycle and plant stature itpromotes an increase in the number of nodules. The increase in cycle and plant stature it promotes an increase in thenumber of nodules. It is possible to obtain satisfactory results for the agronomic traits evaluated with the replacement ofnitrogen fertilization of mineral coverage by inoculation.
