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
