SANCHEZ-HERRERA, J.H.; OLIVA, M.; COLLAZOS, R.  y  MELENDEZ-MORI, J.B.. Efecto de la fertilización y aplicación de fitohormonas sobre la floración y rendimiento de Hylocereus megalanthus (K.Schum. ex Vaupel). RIA. Rev. investig. agropecu. [online]. 2022, vol.48, n.2, pp.155-159. ISSN 1669-2314.

The objective of the study was to evaluate the effect of the application of different doses of fertilization and phytohormones on the flowering and yield of H. megalanthus (K.Schum. ex Vaupel). The evaluations were carried inhomogeneous experimental units, with 2.5-year-old pitahaya plantations. A completely randomized block experimental design with a factorial arrangement was established, consisting of nine treatments and three replications. The data obtained were subjected to an analysis of variance and a comparison of means (Tukey, p<0.05). The results showed that the application of fertilization, phytohormones, and their interaction significantly influenced flowering, fruiting, and yield, managing to increase their values with the application of 136 g plant-1 of NPK+ 138 ppm of phytohormones. However, fruit characteristics (weight, length, and diameter) were not significantly modified by the treatments.
