| Sumario: | The grown under cover soils deteriorate by irrigation with saline water and lack of leaching by rain. Drainageeffects on tomatoes yield and soil moisture and salts distributions were evaluated. In a greenhouse 6 loinswere built, on three of them PVC pipes and tanks of 0.2 m³ were buried 0.5 m in the discharge. In the loins,drip tapes were placed in three depths: 0.1 and 0.2 m (T1 and T2) and surface (T3), setting 6 treatments, 3with drainage T1CD, T2CD and T3CD and 3 undrained T1SD, T2SD and T3SD. Volumetric water contentWv was determined at 6 sites loin with sensors Decagon, 3 on the vertical axis and 3 on the horizontally axisand pH, electrical conductivity CE and sodium adsorption ratio SAR in soil samples taken at the surface,bottom and side of the loins. Weight and number of fruit over 10 plants per treatment were recorded. Themain results were: a) the differences between Wv media were statistically significant on the vertical axis, butnot for the horizontally axis; b) drainage favored both the Wv storage and the distribution uniformity; c) thesubsurface drip irrigation produced drainage volumes, not the surface drip; d) T2CD took top overalltomatoes yield and fruit number; e) drainage practically unchanged pH, decreased the CE 35.8% and 17% theSAR; f) the productive response was associated more to irrigation than salinity conditions.
