Resumo
One way to mitigate the irrigation costs is to use chemigation, since the costs of tractor operations are minimized. However, this reduction in costs is specific to each agricultural system. Thus, this work proposes to quantify the reduction of these costs and the consequent increase in the profitability, for an area of 80ha irrigated with central pivot, with successive cultivation of soybean, corn and industrial tomato for the State of Goiás. For this were calculated using the Amazonsaf software for a 30-year project adjusted with a TMA of 12.0%. The technical coefficients of production obtained by FAEG and the financial indicators were calculated: Net Present Value (NPV), Internal Rate of Return (IRR), Cost Benefit Ratio (B/C) and Payback. The results showed that there is economic viability of the independent enterprise in the way fertilizers and pesticides are applied. The NPV was R$1,712.46ha-1.year-1 and R$1,477.52 ha-1.year-1, IRR of 31.94% and 27.98%, B/C of 1.31 e 1.27, and Pay Back of 4 and 5 years for chemigation and conventional, respectively. It is observed that in the system with chemigation there is a reduction in the cost of production and profitability increased by 2.68%.
