Mandioca irrigada: análise da viabilidade econômica.

Abstract

The present work has as objective the economical evaluation of the cultivation of the cassava under irrigation in an uncertainty situation regarding the benefits that the technology can provide. The cassava is known as a resistant culture to the drought, the use of the irrigation in that culture can be justifies in some circumstances, which promote an answer in the increment of the productivity contemplating in a better return for the producer. The sensibility of the solution can be examined for countless variables, however, the variation of values for all the variables of a project can produce results difficult of be synthesized. Like this, in practice, it is convenient to choose some varied more sensitive and to analyze the profitability of the project being varied one of every time. A usual method to analyze the uncertainty is to esteem one or more factors considering the conditions optimist and pessimistic, to investigate the effect of those variations on the results of the analysis. That work indicates that the cultivation of the cassava under irrigation has 77% of probability of giving profit.
