Viabilidade econômica da irrigação de cana-de-açúcar no cerrado brasileiro. Irriga, Botucatu , n. esp. 2, p. 149-157, 2015.1808-8546http://repositorio.bc.ufg.br/handle/ri/13995This study aimed to evaluate te economic viability of sugarcane irrigation in the Cerrado region in function of perspectives of return associated with different irrigation management: i) full blade (493.56 mm year -1 ); ii) supplement with deficit (50% of water requirement, 235.37 mm year -1 ); iii) rescue (80 mm year -1 ). The total cost of the managements of full irrigation, supplement with deficit and rescue in cane plant stage were 1* US$ 4,955.71 ha -1 , US$ 4,179.61 ha -1 , and US$ 2,712.92 ha -1 , respectively. The indicators analyzed showed that irrigation in sugarcane generates over 30 years of investment in full irrigation management VPL = Recebido em 11/06/2015 e aprovado para publicação em 25/06/2015150 Viabilidade econômica da irrigação... US$ 620.39 ha -1 year -1 , TIR = 61.11%, Payback = 3 years and Ratio B/C = 1.7. In the deficit irrigation VPL = US$ 433.89 ha -1 year -1 , TIR = 52.99%, Payback = 3 years and Ratio B/C = 1.5 and in the rescue irrigation, VPL = US$ 309.46 ha -1 year -1 TIR = 91.48%, Payback = 3 years and B/C = 1.4. The full irrigation presented the highest profitability, followed by irrigation with deficit with profit 30.06% lower, and rescue equipment, with a 50.11% lower profit that full irrigation US$ = R$ 3,18 07/07/2015porAcesso AbertoManejo da irrigaçãoCerradoSaccharum spp.Análise econômicaIrrigation managementCerradoEconomic analysisSaccharum spp.Artigo10.15809/irriga.2015v1n2p149
