Viabilidade econômica da produção de pimentinha-verde submetida a diferentes lâminas de irrigação

Abstract

Irrigation is a technology that requires significant investments and is associated with intensive use of agricultural inputs, making important economic study of the components involved in irrigated agriculture. The objective of this study was to perform an economic analysis based on the theory of production costs, obtained by comparing the average revenue or price received by the product with the average total costs generated in the production system of pepper cv. Lupita on different irrigation blades. The experiment was conducted in the area of the experimental Farm of the Federal Rural University of Amazonia (FEIGA), Igarapé-Acu-PA. The cultivation used was Lupita, spacing of 1.2 m between rows and 0.80 m between plants. A randomized blocks (DBC) with five treatments and four replications, the treatments consisted of five water depths applied percentages function evaporated blade tank class “A”, namely: T30 = 30%, T60 = 60%, T90 = 90%, T120 = 120%, T150 = 150%. For the estimation procedure of the production cost was realized the sum of the values of all resources and operations used in the production process, from production of the seedlings until the third harvest occurred at 120 days after planting. We used the calculation of depreciation and the alternative costs. To estimate the cost of producing this work values we were approached in Brazilian reais (R$). It was found that productivity was affected by the water replacement levels, with maximum reached to 101% of ECA. And the total costs varied inversely with respect to the profits. The improved economic performance was identified at 101% of ECA.
