The objective of this study was to evaluate the economic viability of the irrigation of the Pupunha crop in Ilha Solteira, São Paulo, Brazil for the local parameters. Through the program Pupunha, being obtained a family of comparative curves for several situations. The effect of the cost of the water was studied associated with the irrigation levels. The sensitivity of the equipments due the variation of the life useful was studied associate to the type of used motor. Using the yield of the no-irrigate palm heart of 700kg ha-1 and yield of the irrigated palm heart of 2500 kg ha-1, for all the accomplished simulations, the income of the production increment overcomes the cost of the irrigation, supplying profit to the producer.
