VARGAS, Alfonso. Evaluation of cultivars and planting materials in False Horn plantain type under intensively management plantation. cultrop [online]. 2015, vol.36, n.2, pp.72-82. ISSN 0258-5936.

Growth and production variables were measured in three experiments in the Costa Rican Caribbean zone, where two False Horn plantains phenotypes and their cultivars (experiments 1 and 2) also five planting materials (experiment 3) were compared during the plant crop. Cultivars of Harton phenotype had less bunch weight, number of hands and fruits (p<0,0001), but with thicker and larger (p<0,0073) fruits than those of Dominico Harton phenotype. Thus, Hartón phenotype cultivars should be oriented to the exportation market as fresh green fruit and Dominico Hartón phenotype cultivars to the industry. From the Hartón phenotype group, Hartón I and Tallo Verde I gave the best yield production while in Dominico Hartón phenotype, Dominico Hartón and Cobano were the best. Between planting materials the two treatments that included sword suckers (experiment 3) were more precocious (p=0,0003), and although no significant difference in yield (p>0,0899) was observed with the other treatments were, together with in vitro plants, which had the best overall performance. In addition, the use of water sucker could be also an alternative for planting, because are abundant in the mat, after harvest of the mother plant, and give uniform plantations as the sword suckers
