Abstract

The present work aims to study the economic feasibility of installing an irrigation system a central pivot, the soybean crop in the municipality of Alegrete / RS. According to the objectives, the study is classified as bibliographic and technical procedures regarding the case study research was used, starting from data provided by the farmer. Irrigation is a very effective technique because it meets the need of water the plant needs for its development. Largely responsible for the reduction in soybean production and alteration in the plant water deficits during the entire plant, especially in seed germination and flowering - energy - grain filling. This paper presents a study by methods for evaluation of investment projects as payback, IRR and NPV. 6 ( six) different scenarios were constructed to compare the results , proving to be feasible in all scenarios proposed for this study , highlighting the best result for the producer , scenario 3 with the following results : NPV = R $ 6,298.73 ; TIR = 22.80 % and Payback = 5 years . According to our analysis, it was concluded that the irrigation system center pivot can be an excellent investment alternative for the producer.
