SOFTWARE FOR MANAGING LOCALIZED IRRIGATION SYSTEMS IN FRUIT TREES - DOI: 10.7127/rbai.v11n500750

Resumo

We developed a computer program for managing localized irrigation schedules, which is based on the crop evapotranspiration (ETc). The reference evapotranspiration (ETo) can be estimated by the FAO’s standard method, Penman-Monteith, and by four more alternative methods (Priestley-Taylor, Jesen-Haise, Hargreaves-Samani and Class A evaporation pan) in case the user does not have all the necessary climatic variables for estimating the ETo by the standard method. The program estimates the crop coefficient (Kc) of fruit trees, such as mango, banana, papaya, grape, guava, passion fruit, and citrus, which are commonly grown fruits in the Semiarid of Bahia. It allows estimating the daily irrigation run time of these crops, not being restricted, however, to them. The application was developed in Object Pascal programming language through the integrated development environment (IDE) Lazarus 1.6, which enabled the creation of a simple and friendly interface, as well as accurate calculation routines.
