Análise econômica da alface americana em monocultura e consorciada com pepino japonês em ambiente protegido

The experiment was carried in green house at Unesp, Jaboticabal-SP, in the period of August and November, with objective to evaluate the production cost and crisphead lettuce "Lucy Brown" profitability in monoculture and in intercropping with Japanese cucumber "Hokushin" in protected environment. The production cost determination was performed on total operational cost (COT) basis. The crisphead lettuce in monoculture estimated COT and in intercropping was R$ 657,57 and R$ 159,95/614,4 m(2) respectively. The productivities of 623 and 730 kg/614,4 m(2) in the experiments had provided gross incomes of 286,58 R$ and 335,80/614,4 m(2). It was verified a loss of R$ 370,99/614,4 m(2) in the crisphead lettuce monoculture and an operational profit of R$ 175,85/614,4 m(2), in protected environment when in intercropping with cucumber.

Viabilidade econômica do cultivo da alface crespa em monocultura e em consórcio com pepino

The protected culture, among other advantages, made possible to diminish the seasoning in offers and to improve the quality of vegetables. However, one consists in technology of high cost, that it may be attenuated with the increase in the efficiency of the use of the protected area, proportionated for the intercropping. The experiment was carried out at greenhouse at UNESP, Jaboticabal-SP, in the period of August and November of 2005, with the aim of evaluating the operational cost (COT) and the profitability of the crisphead lettuce "Veronica" (Lactuca sativa L.) in monoculture and in intercropping with the Japanese cucumber "Hokushin" (Cucumis sativus L.), in protected environment. The main cost items analyzed were the operational cost, the agricultural amendments and the materials cost. For the crisphead lettuce in monoculture and in intercropping, the COT was R$ 696,37 and R$ 295,06/614,4 m(2) respectively and the productivity was 822.53 and 890.78 kg/614,4 m(2). In monoculture and in intercropping the gross incomes were R$ 489,93 and R$ 452,39/614,4 m(2) respectively. It was verified a loss of R$ 206,44/614,4 m(2) in the crisphead lettuce monoculture and an operational profit of R$ 157,33/614,4 m(2) in protected environment when in intercropping with cucumber.
