The tomato is a source of vitamins, minerals and bioactive substances beneficial to human health, has a wide range of fresh use and is an important raw material for the processing industry. In order to increase its productivity, it has been involved in cultivation in substrates, in which, irrigation is one of the most important factors to consider, since according to the physicochemical properties of the growth medium and the water needs of the plant has an efficient use of water and fertilizers. Therefore, the objective of the present work was to evaluate the volume and frequency of irrigation as a function of the water retention capacity of the substrate, as well as the volume of drainage on the yield and quality of tomato fruit ball Zyanya variety. The research was carried out in Nayarit in 2013 and 2014. The treatments consisted of tezontle and mixture of tezontle with vermicompost as substrate with irrigation to 80% of nutrient solution Steiner and the control was tezontle with irrigation to 100% of nutritive solution. The irrigation volume and frequency were established according to water retention capacity (CRA) of tezontle. The yield, color, diameter, firmness, total soluble solids (TSS) and percentage of fruit acidity were evaluated. Significant differences were found in the variables evaluated. The yield was 149 t ha-1, SSTs were found between 4 and 5.17 °Brix, citric acid ranged from 0.33 to 0.535%. It was concluded that vermicompost had a positive influence on CRA, due to the fact that there was a greater availability of water and nutrients, consequently a higher yield was obtained.
