In this study it was simulated the cost of irrigation by a center pivot system under different pressurized pipe length and topographic levels in the brown bean growing, as well its profit. It was considered an irrigated area of 103.58 ha, being set the most economic system configuration from the considered variables. The cost of irrigation in brown bean growing ranged from 14.8 to 21.5% between the extreme conditions, in the lower topographic level (40 m) and pressurized pipe length (2,000 m) to the largest topographic level (80 m) and length (3,000 m). In all irrigation system settings and with prices in August 2008 or the average historic price it would be viable the brown bean growing, providing profits until R$ 3,959.64 and R$ 1,203.14 ha-1, respectively.
