The growing demand for water resources due to the difficulty of access, capture and storage, quantity and quality, minimum volume required for food production, especially in the semiarid region, has an estimate of research and practice of practices that aim to improve or use the techniques used to use low quality water as an alternative to supply the water demand of small irrigators. The tomato crop is very demanding in water, its water demand requires an irrigation practice to obtain an optimum dry crop production in the season. Through the technology of economic channels, it is possible to save water in tomato production through subsurface irrigation. The objective is to evaluate the growth and production of tomato under different irrigation depths in the economic channels with mulching, applying or increasing in family farming. The experiment was conducted in the factorial scheme (5 x 2) x 4, with subdivided plots, in the DBC, without which was the effect of 5 irrigation depths (50%, 75%, 100%, 125% and 150% of ETc) on two tomato cultivars: RIO GRANDE (Lycopersicon lycopersicum) and CALINE IPA-7 (Lycopersicones culentum Mill.), arranged in four replications. The EVALUATED characteristics were: plant diameter (DC); Plant height (H); number of leaves (NF); lateral branches (NR); number of floral branches (NRFL); weight per fruit (P / F); average fruit diameter (DIA); volume (VOL); density (DS); production (PROD) and productivity (PRODT) and water use efficiency. An IPA7 cultivar does not differ statistically in terms of water use, showing that it is possible to produce tomatoes with low water consumption and 75% undifferentiated production and use when compared to a standard that obtains, therefore, a saving of 25% of (100 % Etc). According to these results, the applied technology of economic beds with mulching is ideal for saving water in food production aiming at water use efficiency in family farming.
