    Currently the kidney tomato is most cultivated vegetable in the world, for its nutritional content and its application in the daily diet. The water needs of the tomato crop and use the same dependent integration of climate, soil and botanical factors. Irrigation is essential to ensure high levels of production; the frequency and quantity (sheets) of this depends on the state of development of the crop; greenhouse climatic conditions and soil type. Bolívar province there are no real studies that include indicators of amount and frequency of irrigation system under greenhouses. The objectives in this research were. i) Study the response of the 3 engravin y of water for Hybrid Tomato Kidney Michaella greenhouse ii) Evaluate the effect of three irrigation intervals for tomatoes kidney iii) Tomate an economic analysis of the benefit / cost of the best treatment. This research was conducted in the town Yagui, San Miguel canton. Block design (RCBD) was used. The main results were: The average yield of hybrid tomato Michaella was 11589.3 kg / ha. There was a significant effect of the engravin and irrigation frequencies on the yield. The highest average was recorded in the A3 (650 mm) with 13502.33 kg / ha for irrigation frequencies the highest average was evaluated in B1 (4 days) with 13750.97 kg / ha. For the AxB interaction were dependent factors with the highest average in T7 (A3xB1) with 16346.15 kg / ha. The components that increased the yield of hybrid tomato Michaella were: Moisture content before and after irrigation, plant height and inflorescence insertion, number of fruits per plant, polar and equatorial diameter of the fruit. The variable yield was reduced drought stress during the crop cycle. Furthermore, this study showed that in this agro- ecological zone water bodies and irrigation frequency was insufficient to meet the water needs of the crop. The best net benefit introduced T7 (A3B1) treatment with a RB / C of 1.09
