%X the objective of this work was to evaluate the response of tomato hybrids to three fertilization-watering programs based on recommendations of dose compiled from the literature (lit), curves of absorption (ca), and adjustments of information previously analized (aju). from october 2008 to march 2009, two tomato hybrids (fb-17 and drd-8108) were grown in the greenhouse of the fabio baudrit moreno agricultural research station in alajuela, costa rica. no significant statistical differences were found in the commercial performance in none of the three fertilization treatments; significant differences among the hybrids were observed. the hybrid drd-8108 surpassed fb-17. fb-17 hybrid yield for treatment lit was 69.3 t/ha and 5.87 kg/plant; in the ca treatment was 75.5 t/ha and 6.39 kg/plant; and in the aju treatment 76.4 t/ha and 6.62 kg/plant, respectively. for the drd-8108 hybrid, the lit treatment yield was 85.4 t/ha and 8.55 kg/plant; in the ca treatment was 86.7 t/ha and 7.45 kg/plant; finally in the aju treatment yield was 83.9 t/ha and 7.38 kg/plant. the high internal greenhouse temperature was the main limiting factor that constrained yield.
