Potencialidad nutricional del ensilaje de king grass (Pennisetum Sp.) con fertilización orgánica.

Abstract

The objective of this research was to evaluate the nutritional potential of King grass (Pennisetum sp.) silage using three types of organic fertilization applied at field level in the experimental farm Río Suma belonging to the Universidad Laica Eloy Alfaro de Manabí; for this purpose, four treatments were evaluated: T1 (Biocompost), T2 (Biol), T3 (Control) and T4 (Humus), implemented in a Complete Randomized Design. It was concluded that the nutritional evaluation of King grass fertilized with Biocompost had the following characteristics: moisture 81.14 %, crude protein (PB) 11.89 %, ethereal extract (E.E) 3.51 %, ash 13.65 %, fiber 34.44 % and non-nitrogenous elements 36.50 %; the results showed highly significant differences (p<0.01) between the different organic fertilizers applied at field level; with the exception of moisture. There was no effect on the production of green matter (GM) and dry (DM) of the silages evaluated (p>0.05). The economic analysis showed that T1 (Biocompost) had the highest marginal rate of return (3.32 %), making it the most profitable from an economic point of view.
