In the present paper, we report the results of the effect of substrates and different concentrations of nutrient solution in the nutrient content of leaves, growth and yield of tomato hybrid Charleston, grown in greenhouse at the Graduate School of Agricultural Sciences, Montecillo, Mexico State in 2008-2009. N, P, K, Ca, Mg, Fe, Cu, Zn, and Mn content was evaluated and also, the variables SPAD readings, leaf number, plant height, stem diameter, leaf area, leaf dry weight and yield. The treatments were mixed of tezontle with two types of vermicomposts in a ratio 65:35, plus water application and nutrient solution of Steiner at 50, 75 and 100%. It was considered a factorial design 2x4 in a completely randomized design using eight replications. It was found that, the nutrient solution at 50% was the best treatment, and that yield is not diminished in relation to the treatments where the concentration was 75 and 100%, although the concentration of N, P, Mg, Fe, Cu, Mn, and the variables SPAD readings, leaf area, leaf dry weight and plant height were higher with the 100% solution. There was no difference between the vermicomposts used in the different variables. It was concluded that, the vermicompost-tezontle mixture in the ratio used was suitable for growth of tomato Charleston, while allowing to reducing inorganic fertilizers without affecting yield.
