Eficiencia forrajera del pasto Brachiaria brizantha cv. xaraes utilizando diferentes niveles de biol en el Rancho Vuelta Abajo Agrícola Ganadera

Abstract

The objective of this research was to determine the forage efficiency of Brachiaria brizantha cv. Xaraes using different levels of Biol (0, 2, 4, 6) l/ha at Rancho Vuelta Abajo Agrícola Ganadera. This work had a duration of 90 days, in which the grass and the study site were identified, as well as the descriptive variables, on the other hand, for the statistical variables a completely randomized design with 4 replications was used, where the size of the experimental unit was 20 m2, with a total area of 320 m2, in accordance with a cut of equalization of the plots. Therefore, fertilization was applied at 5 days of regrowth and data were taken at the pre-flowering stage, which was achieved 26 days after the rest period. The experimental results obtained showed highly significant differences (P≤ 0.01) for the variables height (0.74 m), basal cover (47.5 %), aerial cover (78.92 %), number of stems per plant (31.09), fv/t/ha/cut (14.46) and ms/t/ha/cut (2.76) with treatment B3 of 6 l/ha; while for the variable number of leaves per stem it did not present statistical differences. In such virtue the higher productivity of green forage and dry matter is achieved with treatment B3 because it is related to the nutritional contribution and agronomic performance of the plant, as well as the cost benefit is more efficient in the same treatment. Therefore, the constant search for environmentally friendly alternatives is recommended, in addition to being sustainable and sustainable for small and medium producers.
