Efecto de la edad de corte sobre la composición química del pasto clon 51 (pennisetum sp).

Abstract

This experimental research was developed with the objective of evaluating the productive performance and morphological characterization of the Clone 51 (Pennisetum sp.) varietal at three cutting ages of 70, 80 and 90 days. It was carried out at the Pinar del Río farm, of the Agrodímeza company, located at Km 29 of the road to Santo Domingo – Chone, in the El Carmen parish of the El Carmen canton in the north of the province of Manabí. For this purpose, a completely randomized block experimental design (DBCA) was obtained, which consisted of three treatments with 7 repetitions; The chemical analysis of the content of crude protein, ether extract, inorganic matter, crude fiber and nitrogen-free extract was performed, using the Analysis of Variance (SC Type III) indicating significant differences with Tukey's test (p<=0 .05) that according to the results, the cutting age does influence to chemical composition of Clone 51 grass (Pennisetum sp). At the age of 70 days, the cutoff is favorable for the variables of crude protein (11.83), extract free of nitrogen with (40.80) and for the variables of ethereal extract (3.41), inorganic matter (13. 40) crude fiber (35.60) presenting high content at 90 days. Therefore, it was concluded that the ideal cutting age is 70 days to maintain better nutritional values.
