Avaliação econômica da irrigação em pomares de açaí

Abstract: Tendo em vista a importância do açaí para fruticultura paraense, o presente trabalho teve como objetivo determinar o acréscimo mínimo de produtividade (AP), em relação à produtividade do açaí de sequeiro, para compensar os gastos com a irrigação. Os APs, os custos fixos e variáveis da irrigação foram calculados com base em simulações de diferentes cenários de investimento em irrigação, tipo de acionamento do motor, preço do açaí e produtividade de sequeiro (6.000-16.000 kg ha -1 ). Dentro dos cenários estudado… Show more

“…According to Souza and Jardim (2007), soil water availability is an important factor for the survival and productivity of this tree. For this reason, producers have been using irrigation technology for water supply purposes, especially in places where drought is prolonged (Souza et al 2013). However, their choice of irrigation depth is empirical.…”

“…Irrigation management must be performed by farmers with a view to providing adequate water supply and achieving high-level agricultural yield. However, it is crucial that they are aware of water requirements or evapotranspiration (ET c ) of a given crop at different stages of development (Souza et al 2013). Indeed, the rational use of water for irrigation purposes and the correct design of irrigation systems, as well as efficient water management, depend, among other prerequisites, on knowledge of accurate crop water requirements (Canales-Ide et al 2019).…”
