Abstract : Under conditions of greenhouse and field a dozen varieties of tomatoes were planted to test their tolerance to drought. Conducted with four levels of Altattiyh. The work aims to compare the response of the four varieties of water levels of tension. Where irrigation levels 1, 2, 3 and 4 day, two days, three days. The plants were planted by statistical analysis (random dissident sectors). We have collected information to evaluate the ability of species to withstand various levels of tensile strength of water. In addition to the dry weight of shoots (leaves and stems) in addition to leaf area. This information is useful in calculating the growth of plants in addition to the number of flowers and clusters. In the third experiment information to transpiration and evaporation have been collected in addition to information about weather in the greenhouse and the field of heat and moisture ... Etc., and the number of constraints in agriculture, such as insect infestation, birds, and rain and sandstorms. These factors lead to rapid death of plants, so the experiment was terminated and replanted again in the winter of 1991.
