| Abstract: | This work aimed to analyze the economic feasibility of the irrigation system by dripping and nitrogen fertilization in jambu production. The experiment was conducted at the Experimental Farm of Igarapé-Açu, a site owned by UFRA, in protected cultivation, from May to July in 2016. The treatments consisted in four soil water tensions (12, 18, 24 and 30 kPa) and four nitrogen doses (0, 50, 100 and 150 kg ha-1). The economic analysis of the jambu irrigated production was sustained by the theory of producing costs considering both depreciation cost and alternative cost. The treatment with the highest profit was managed at 18 kPa with a nitrogen dose of 50 kg ha-1, with a profit of R$ 1,548.54 for an area of 1,000 m.². The drip irrigation and nitrogen fertilization were economically viable for the jambu crop. |
