No signifi cant statistical differences</p><p>were found in the commercial performance in none of the</p><p>three fertilization treatments; signifi cant differences among</p><p>the hybrids were observed. The hybrid DRD-8108 surpassed</p><p>FB-17. FB-17 hybrid yield for treatment LIT was 69.3 t/ha</p><p>and 5.87 kg/plant; in the CA treatment was 75.5 t/ha and</p><p>6.39 kg/plant; and in the AJU treatment 76.4 t/ha and 6.62</p><p>kg/plant, respectively. For the DRD-8108 hybrid, the LIT</p><p>treatment yield was 85.4 t/ha and 8.55 kg/plant; in the CA</p><p>treatment was 86.7 t/ha and 7.45 kg/plant; fi nally in the AJU</p><p>treatment yield was 83.9 t/ha and 7.38 kg/plant. The high</p><p>internal greenhouse temperature was the main limiting factor</p><p>that constrained yield.</p>}, number={1}, journal={Agronomía Mesoamericana}, author={Quesada-Roldán, Gustavo and Bertsch-Hernández, Floria}, year={2012}, month={Jun.}, pages={117–128} }
