There were evaluated the yield, fruit quality and nutritional status of single truss and long shelf life tomato, cultivated in nutritive solutions prepared with different nutrient sources. The experiment was carried out from 04/05/99 to 13/09/99 in a greenhouse of the Universidade Federal de Viçosa, Brazil. Two groups of nutrient sources were tested to prepare the solutions for vegetative growth and two groups for the frutification solutions. The combinations of those groups gave rise to four treatments, disposed in the randomized blocks design with eight repetitions. Seedlings of the F1 hybrid Carmen 36-day old were placed in 8,6 L vases, spaced 0.35 x 0.70 m. The yield, fruit quality and nutritional status of the plants were evaluated, as well as the partition of Ca, Mg and K in the fruit. The data were submitted to analysis of variance and the means were discriminated using Tukey at 5% of probability. There were no significant differences among treatments. The average yield per plant was of 920 g, with an average plant cycle of 96 days, corresponding to a yield of 142 t ha-1 year-1. The concentrations of N, P, K, Ca, Mg and S in leaves were, respectively, 3.18; 1.25; 5.11; 4.50; 0.88; and 1.79 dag kg-1, and concentrations of Fe, Zn, Cu, Mn and B were, respectively, 209; 96; 10; 665; and 209 mg kg-1. In the fruit, Ca and K were presented in larger concentration in the proximal area, unlike Mg, that was present only in lower concentration in that portion.
