Comparación de la eficiencia de tres bioestimulantes en Ochroma pyramidale (balsa) bajo etapa vivero, parroquia Puerto Francisco de Orellana

Abstract

One of the main problems in balsa growth (Ochroma pyramidale) in nursery is lack of information on biostimulants. The work objective was to determine the efficiency of three biostimulants for balsa (Ochroma pyramidale) in nursery stage, in Puerto Francisco de Orellana parish. The methodology used had a quantitative approach, a completely randomized design with repeated measures was used, with a distribution of 4 treatments, 3 replications, 12 experimental units. For statistical analysis, The Past 4.13 software was used in the development the analysis of variance (ANOVA). The variables analyzed were seedling height, number of leaves, stem diameter and root length. The results show that T2 was more effective with 25.01 percent based on dry weight to the control. In morphological parameters, T2 showed greater height with 23.40 cm and root length 27.7 cm. However, 45 days the variable number of leaves showed no statistical difference between treatments, while in the variable stem diameter T3 showed better results with 0.37 cm the control 0.22 cm. In the analysis of morphological parameters, T2 was the best in terms of biomass increase. It is concluded T2 treatment was effective in terms on dry weight gain. Treatment T2 showed high results in terms of variables height, root length, leaf size and shape, in addition, Evergreen was considered the best at end of assessing in the variable stem diameter for presenting values 0.37 cm versus 0.34 cm of Quantis.
