Abstract

The present research proposes: to evaluate the effect of 25 – 16 – 12 application with foliar fertilizer in the growth of Caesalpinia spinosa (Guarango), plants at the Catiglata nursery, from La Peninsula Parish, in Ambato Canton from Tungurahua Province. Helping us with Guarango plants and a complete foliar fertilizer with 25% N, 16% P, and 12% K, of which 3 doses of foliar fertilizer were used (2, 4 and 6 grams), with a frequency of application to (7, 14 and 21 days); the same one that, on having got together, there produced an experimental desing of finished blocks at random with bifactorial arrangement, with 9 more treatments, a technical witness and 3 repetitions, so 30 plants for treatment and 12 plants evaluated by each one. The following variables were evaluated: height of plant, diameter of stem and number of leaves per plant in 30, 60, 90 and 120 days. Thus, getting non-significant results for the variables: height plant and stem diameter in none of periods from data taking, by contract taking highly significant results in the studied variable, number of leaves to the 90 days, when applying the high dose (6 grams of fertilizer per 1 liter of water) with an average of 13,24 leaves per plant, as well as highly significant results to the 120 days with A2B1 treatment (4 grams of fertilizer per 1 liter of water being applied every 7 days) with an average of 15,86 leaves per plant. It is concluded that, the application of foliar fertilizer increase the number of leaves per plant of Guarango (foliar growth), this being positive in the diameter growth and height of the plant. Key Words: foliar fertilizer – Guarango plants – native forest species.
