This study had the aim to verify the economic feasibility of japanese cucumber (Cucumis sativus L.) yield under different irrigation depths, cultivated in greenhouse. A completely randomized design (CRD), with five levels of replacement of irrigation water (50, 75, 100, 125 and 150%) and six replications was used. The results showed that the number and fruit weight of crop were affected by treatments of water deficit and excess used for treatments. The maximum productivity obtained was equal to 45,944 kg ha-1 for a depth of 320 mm and the economic optimum irrigation depth was estimated at 319.5 mm, concluding that for the japanese cucumber higher economic returns are obtained by keeping the crop with soil water content near field capacity, restoring the full amount of water consumed.
