Résumé:
The production of soybeans and corns has great importance in the economic
scenario of the region west of Paraná, however, the frustrations of crop are
frequently due to climate instability, in particular the low volume or uneven
distribution of rainfall during the culture cycle. The supplemental irrigation is an
alternative to maintaining and increasing productivity in several regions of the
country, however, are few initiatives in western Parana, even with abundance of
water in the reservoir of Itaipu. In this context, this study aimed to evaluate the
efficiency of the current model of agricultural production, as well as the economic
viability of irrigation use in the production of grains in the western municipalities of
Paraná, using documentary research and application of deterministic methods IRR,
NPV and VEUA. It found a dependency relationship between rainfall and productivity,
resulting in low efficiency of the current production model, where the seven seasons
of the series analyzed, three have productivity levels below 50% in the five boroughs.
In the analysis of economic feasibility of using supplemental irrigation in different
scenarios designed, the results indicate that the use of irrigation in the production of
annual crops is financially viable in the rural properties of the region West. Paraná;
the return on investment is about 18% per year.
