SIRRAD - software de projetos de irrigação e recomendação de adubação para região do alto sertão paraibano.

Abstract

The SIRRAD computer program was developed to assist the farmer to determine the needs for acquiring inputs (irrigation equipment and soil-corrective chemical properties). Thus, three components were outlined: SIMPLIFIED VERSION, TRACK VERSION and FERTILIZERS AND LIME, which can be intertwined. The first component is focused on the middle region of “alto sertão” of the state of Paraíba and includes the design of irrigation projects for the amount of chemicals necessary for the correction of the area occupied for fifteen cultures of potential exploration in the region. The scaling is performed for eighteen fixed layouts (suggested) and two types of trickle irrigation (drip and microsprinkler), only requiring topographic datasets and the producer’s time availability to work in irrigation management. The second component is of global use (for the method of trickle irrigation) and is directed especially to professionals. The last component favors the acquisition of liming and fertilization for fifteen cultures following the method recommended by the Empresa Pernambucana de Pesquisa Agropecuária (IPA) [Agricultural Research Company of the State of Pernambuco].
