Evaluación productiva de Dactylis glomerata (pasto azul) mediante la utilización de tres fuentes orgánicas en un sistema silvopastoril.

Abstract

The objective of the research was to evaluate the productivity of Dactylis glomerata (Blue Grass) by using three organic sources in a silvopastoral system. In the San Juan parish, Riobamba canton, Chimborazo province with three types of organic fertilizers (Fertiplus 4t / ha, Humus4t / ha and Gallinaza 4t / ha) compared to a control treatment. The investigation lasted 60 days, which was distributed under a completely randomized block design and separation of means according to tukey. In the evaluation of the productive behavior, the best responses when evaluating the percentage of basal coverage was achieved by applying humus where data was obtained at 15 days (40.50%); 30 days (54.30%); 45 days (65.70%) and 60 days (82.80%). The highest percentage of aerial coverage was achieved by fertilizing the plot with humus, registering values at 30 days (66.40%); 45 days (85.17%) and 60 days (95.24%). When evaluating the height of the plant, superiority was appreciated when using humus as fertilizer, where results were obtained at 30 days (26.23 cm); 45 days (35.71 cm) and 60 days (50.04 cm). In addition, a better yield was obtained in green forage production when using humus, reaching 12.44 t / ha / cut. While I register a higher production in dry matter when using Chicken Manure with 2.89 t / ha / cut. A higher cost benefit was also obtained when using humus where the report was 1.73, that is to say that for every dollar invested, a profitability of 73 cents is obtained. It is concluded that the best response was obtained when fertilizing the plots with organic fertilizer (humus) in the forage production of Dactylis glomerata (Blue grass). The application of humus as a fertilizer is recommended since it does not present negative effects on the quality of the soil and a better productivity is obtained.
