Water use optimization through alternative water depths in the Formoso Irrigation District

Abstract: A B S T R A C TThis study aimed to propose an optimal cultivation plan using a separable linear programming model, with alternative water depths, that allows maximizing the net revenue of the Formoso Irrigation District (FID), specifically with respect to the area of family plots. The model used in this study was based on data from the 2010 Annual Agricultural Report of the 2 nd Regional Superintendency of CODEVASF (São Francisco and Parnaíba Valley Development Company), the 2011 Service and Extension Plan for… Show more

“…Thus, many studies have been conducted in order to determine crop evapotranspiration and soil water dynamics for the optimization of irrigation systems (Flumignam et al, 2011;Gonçalves et al, 2014;Santos Júnior et al, 2015), as well as to indicate the best cultivation periods, due to the irregularities in the rainfall regimes (Barbieri et al, 2014).…”

“…The costs were evaluated considering the fixed and variable costs of the forage production system (related or not to irrigation) according to functions of net benefit to the farmer proposed by Martin et al (1989), Broner and Lambert (1989), Mannocchi and Mecarelli (1994), Frizzone and Andrade Junior (2005), and Santos Junior et al (2015).…”
