Evaluación del efecto de tres dosis de Fertiestim plus en el crecimiento inicial de capulí Prunus serotina subsp. capuli (Cav.) en el vivero de la ESPOCH.

Abstract

This research aimed to evaluate the effect of three doses of FertiEstim Plus on the initial growth of blackberry (Prunus serotina subsp. capuli (Cav.)) in the ESPOCH forest nursery, in the Lizarzaburu town, Riobamba city, Chimborazo province. With the help of capulí plants and a foliar fertilizer (FertiEstim Plus) with its contribution of 7.2%N; 4.8%P; 3.6% K, 4 different doses of fertilizer (Factor A) were used (0; 0.7; 1; 1.3 ml) with an application frequency (Factor B) (7, 21, 50 days). These ones when combined gives us as a result a randomized complete block design with a bifactorial arrangement with 12 treatments, 4 repetitions and 5 study units per treatment (capulí plants). The evaluated variables were height of the plant (its data collection is carried out from the base of the plant to the apex); diameter of the plant neck (a digital vernier caliper was used in its data collection, which was evaluated at 2 cm from the base of the plant). Leaf numbers (each true leaf of the plant was counted one by one) the data was evaluated at 30, 45, and 60 days. No significant results were obtained in height and neck diameter. Regarding the number of leaves, no significant differences were found, more so in terms of numbers, since its foliar increase was constant. It was concluded that none of the applied treatments gave the best results in terms of the vegetative variables evaluated. From the economic analysis, the best treatment to apply is 0.7 cm3 of fertilizer/L of water since it generates economic gains at a lower cost of application. It is recommended to use new fertilizers with different application doses: 2, 4 and 6 cm3/L of water in Capulí (Prunus serotina).
