Coffee irrigation in Brazil has been justified by the possibility of the culture expansion in areas previously limited due to water deficiency or irregular rain distribution, and in due to water deficiency or irregular rain distribution, and in traditional regions by the offer of production warranty in low precipitation years or when short hot-dry periods occur in the critical phases of fruit development. However, regarding the importance of irrigation for coffee culture, its benefits on productivity and flowering control have not been adequately quantified. This is due, in part, to the fact that the need for irrigation and its function in the control of flowering period are very variable and dependent on rainfall
distribution, drought severity and the type and depth of the soils.
