    With the aim of defining the best commercial hydroponic tomato system under greenhouses, with respect to yield and annual productivity, four production variants based in one stem per plant were compared: a) decapitation of the terminal bud to leave one truss per plant with a population density of 24 plants⋅m-2 (1R24), b) decapitation of the terminal bud to leave two trusses per plant with a population density of 16 plants⋅m-2 (2R16), c) decapitation of the terminal bud to leave three trusses per plant with a population density of 12 plants⋅m-2 (3R12), and d) control without dacapitation of the terminal bud with five trusses per plant and a population density of 6 plants⋅m-2. Floradade, a semideterminate cultivar, was used. The experiment was conducted under a randomized blocks design with six replicates, where each production variant was considered as a treatment. Each experimental unit had a surface of 10 m2 (paths not included). Variables analized were: yield per square meter and its components (mean fruit weigth and fruit number), days from transplant to final harvest, mean truss weigth, mean truss fruit number. Inside each treatment, mean weigth and mean fruit number of each truss were compared (with the exception of 1R24). There were not significant diferences among treatments with respect to yield or its components, but tretament 1R24 reached its final harvest statisticaly earlier than the others. This means the possibilty of more production cycles per year (till 5) and, in consequence, more productivity in an annual basis. As the number of trusses left per plant increased, the mean weigth and fruit number per truss diminished. The tomato production system with more potential of annual productivity and profitabilty was 1R24.

    Keyworks: Management, prunning, short cycles, hydroponic.
