Crecimiento de dos variedades de pitahaya (Hylocereus monacanthus e Hylocereus ocamponis) con aplicación de Ascophyllum nodosum: Growth of two varieties of pitahaya (Hylocereus monacanthus and Hylocereus ocamponis) with apllication Ascophyllum nodosum
The agronomic management of pitahaya can enhance its yield. Thus, the use of Ascophyllum nodosum contributes to plant development. The objective was to evaluate the effect of Ascophyllum nodosum on height, stem diameter, length, shoot diameter and heat accumulation. Two varieties were used: Hylocereus monacanthus (Lem.) Britton & Rose, Hylocereus ocamponis (Salm) Britton & Rose and three doses of Ascophyllum nodosum (0, 1.0 and 2.0 L ha-1), thus, generating six treatments. The variables were analyzed with SAS at 0.05 probability. The average minimum and maximum temperature was 19 and 37 °C and the heat accumulation was 1912 UC. The greatest height was presented by Hylocereus monacanthus with the high dose of Ascophyllum nodosum with an increase of 7 % in relation to the treatment without application. Stem diameter was 16 % greater in the two varieties and with the higher dose compared to the plants without application. In shoot length, H. monacanthus and H. ocamponis outperformed the lowest treatments by 19%. The varieties H. monacanthus and H. ocamponis with applications of high doses of A. nodosum generated the highest values in the variables studied.
