Aplicación de soluciones nutritivas en plantulas de Yagual (Polylepis racemosa) en la comunidad Tiocajas del cantón Guamote, provincia de Chimborazo.

Abstract

The present investigation proposes: to evaluate three solutions of nutritious solutions and two frequencies of application in the growth of the seedlings of Polylepis racemosa (yagual), in the community Tiocajas Palacio Guamote parish of the Guamote canton province of Chimborazo; the following concentration doses were used, 100 - 50 - 100 ppm NPK, 150-75-150 ppm NPK and 200-100-200 ppm NPK, which was applied 40 cc of solution per plant per day, using the following products as source of each element, mono potassium phosphate, potassium nitrate and ammonium nitrate, often applied every 2 and 3 times per week, which when combined produced 6 treatments plus an absolute control with four repetitions, the statistical design used was the completely random block design (DBCA), being evaluated at 30, 60, 90, and 120 days the following parameters height (cm), diameter (mm) and number of leaves. The treatment that gave the best results for the height of plants (cm) after the application of the solution was the A3B2 that corresponds to 200-100-200 ppm NPK and the frequency of application 3 times per week; for the diameter (mm) was the A3B2 which corresponds to 200-100-200 ppm NPK and the frequency of application 3 times per week: for the number of leaves was the A3B2 which corresponds to 200 - 100 - 200 ppm NPK and the frequency of application 3 times per week, therefore, the best treatment is T6 for all the evaluated variables.
