Evaluación del bioestimulante biorma en el crecimiento de plantas de romerillo (Podocarpus sprucei Parl.) a nivel de vivero en la Espoch.

Abstract

This research aimed to evaluate the efficiency of the Biorma Biostimulant and the Biorma Biostimulant enriched with microorganisms for growth in the forest species Podocarpus sprucei Parl. in the ESPOCH forest nursery. The applied methodology was to establish a Completely Randomized design with three treatments and three replications. The trial was located inside the shade house of the forest nursery. The treatments evaluated were: Biorma Biostimulant, Biorma Biostimulant enriched with microorganisms, and control applied at 15, 30, and 45 days respectively, considering height (cm), number of leaves, and shoots of the species. The data for the plant height variable were taken with the help of a ruler graduated in cm, followed by counting the number of leaves and shoots for a later application with the following doses: T1: Biostimulant Biorma (50ml/L), T2: Biostimulant Biorma enriched with microorganisms (150ml/L) and T3: Water (1L), the same applied in 15 days to 90 plants for each treatment and an economic analysis per treatment. The results showed that the Biostimulant Biorma and this enriched with microorganisms are efficient for the growth of P. sprucei Parl plants, with the increase in height, the number of leaves, and shoots. In economic terms, the T1 treatment presents a lower application cost concerning T2 at $235.25. Therefore, using microorganisms based on Trichoderma strains is recommended for possible integrated investigations with organic biostimulants applied in various native forest species of Ecuador to leave aside chemical products.
