Evaluación de las dosis y frecuencias de aplicación del fertilizante foliar fuerza verde en el crecimiento de plantas de Ochroma lagopus (Balsa), en el vivero forestal del Gobierno Autónomo Descentralizado de la provincia de Orellana.

Abstract

The present investigation proposes to evaluate the effect of the application of foliar fertilizer, green force 20 – 20 – 20 in the Ochroma lagopus growth (balsa tree) in the forest nursery of Orellana Provincial Autonomous Govemment. Three doses of foliar fertilizer used (2,5 – 5,0 – 7,5 g) with a frequency of application at (7, 14 and 21 days) which combined they produced a randomized complete block design with a bifactorial arrangement with 9 treatments more an absolute witness and 3 repetitions, 30 plants per treatment, 12 plant evaluated by each one with the following variables: height of plant, number of leaves, length of leaf and diameter of the stem by plant at 30, 60, 90 and 120 days. The obtained results were significant in all the variables of study, they found in high dose of 7,5 g/L (D3) with a frequency of application every 7 days (F1) which generated positive results up to 120 days with respect to the morphological condition of plants, so the rest of treatments surpassed in height by 21,66 %, number of leaves by 29,75 %, leaf size by 16,97 % and stem diameter by 16,82 % in comparison to the absolute witness. The research paper concludes that the application of foliar fertilizer significantly influenced the increase in height, number of leaves, leaf length and stem diameter
