Abstract

The present investigation proposes to evaluate the effect of the application of the foliar fertilizer 20-20-20 on the growth of the Chionanthus pubescens (Arupo) plants in the Catiglata nursery, the Peninsula parish, Ambato canton, Tungurahua province. The organic fertilizer Fuerza Verde was used, whose nutritional composition is 20 % N – 20 % P – 20 % K, which three doses (2, 4 and 6 grams) were taken with a frequency of application (7, 14 and 21) same as when combined produced 9 treatments plus a technical control, being evaluated at 30, 60, 90 and 120 days the parameters: height (cm), diameter (mm) and number of leaves. The treatment that presented the best results for the height was 6 grams of fertilizer / 1L of water every 21 days (T9) with an average value of 33.86 cm; to the diameter the best result was the application of a high doses (6 g/L) and an average of 6.11 mm while to the number of leaves was the application of 6 grams of 20 – 20 - 20 / 1L of water every 7 days (T7) with an average of 29.36. Although no significant differences were observed during the 120 days in the experimental phase due to several factors as the presence of the disease in the leaves and the scarce space to abundant root growth that the plants presented, which could provoke the lack of growth in them.
