Manejo agroecológico de maralfalfa con varios niveles de abono orgánico comercial más una base de enraizador en los suelos de la Facultad de Ciencias Pecuarias

Abstract

In Chimborazo Province, Riobamba Canton, an evaluation of the productive performance of the Pennisetum sp. (Maralfalfa) was performed by applying various levels of commercial organic fertilizer (4, 5, 6 L/ha of Eco hum dx) plus a root enhancer (3 L/ha of Raizplant) in soils of the Animal Science Faculty in order to be compared to a control treatment, the same that lasted for a period of 60 days. We used a Completely Randomized Design (DCA), with 5 repetitions and the TUE (Size Experimental Unit) was 10m2. When looking at the experimental results, it can be manifested that the answers with the best behavior in the height of the plant were recorded after 15 days, with the treatment 1; after 30 days with the control treatment, and after 60 days with the implementation of the treatment 3, which rise to a height of 40.46 cm, 62.86 cm, and 92.68 cm respectively. With regard to the best yields of green fodder and dry matter were obtained, with the use of 6 L/ha of organic fertilizer over a base of root enhancer (T3), reporting productions of green fodder of 14, 96 th/ha/cut and dry matter of 2.45 th/ha/cutting. The highest profitability was recorded by plots fertilized in foliar way with 6 L/ha (T3) of commercial organic fertilizer (Eco hum dx) plus a base of root enhancer (Raizplant 500), reaching a cost-benefit ratio of 1.72. Consequently, it is recommended the use of 6 L /ha of commercial fertilizer for registering the best productive yields, lower production cost, and better cost-benefit ratio.
