Productive behavior of Pennisetum sp to the application of 10-30-10, gallinaza and urea in the canton Morona Santiago

Abstract

Introduction. Pennisetum sp is a tropical grass that is characterized by its high productive yield being demanding to fertilization, reason for which the objective was set. To determine the productive behavior of Pennisetum sp to the application of 10-30-10, poultry manure and urea in the Morona canton. Methodology, the present work was developed at an altitude of 1016 meters above sea level, and an ambient temperature between 15 to 32 °C, whose meteorological conditions were 80% relative humidity, 3000 to 4000 mm of rainfall and 12 hours/day of heliophany; 192 m² of surface were used in which the Pennisetum sp (maralfalfa) crop was established and on which the treatments were applied: 1000 kg/ha of 10-30-10 (T1), 10 Tm / ha of chicken manure (T2) and 10 Tm of chicken manure plus 1000 kg of 10-30-10 / ha (T3); in each treatment 200 kg of Urea were applied, against a control, with four replications, which were distributed considering the mathematical model corresponding to the Completely Randomized Block Design, the crop information was: plant height at 30, 60 and 90 days, green forage production and dry matter. Results. It was demonstrated that the application of 10 Tm of poultry manure, 1000 kg of 10-30-10 plus 200 kg of urea allowed to register heights at 30, 60 and 90 days of 0.66, 1.24 and 1.26 meters and a production of green forage and dry matter of 65.20 and 13.04 Tn/ha, superior to the rest of the fertilization system; it is concluded that the use of fertilizer 10-30-10 + urea in doses of 1000 and 2000 kg/ha/crop allows a higher forage production.
