Alonso, N. Álvarez, R. pasturas tropicales Brachiaria brizantha fertilización química tropical pastures Brachiaria brizantha chemical fertilization The objective of the research was to evaluate the effect of chemical fertilization and soil pH correction, on the yield per hectare and the bromatological composition of the genus Brachiaria, Brachiaria brizantha cv brs Piatã species, subjected to four treatments and evaluated in equal cutting times, simulating a rotary grazing. It was carried out in the city of San Lorenzo, Paraguay. The cuts were made every 35 days after sowing, adjusting the pH plus fertilization according to the technical recommendations, arranged in 4 treatments per block: T1 Control without application of fertilizers or pH correction, T2 Correction of pH without fertilizers, T3 pH correction and application of fertilizers and T4 Fertilization without pH correction. In the performance of Green Matter, according to the analysis of variance (ANAVA) that was applied to the average obtained from each cut according to the treatments, following the random blocks statistical model, it showed significant differences with a confidence level of 95% and applying the Tuckey test for comparison of means (p<0.05) in favor of T3 in relation to the other treatments. Regarding the bromatological composition, regarding the percentage of dry matter, significant statistical differences between treatments were evidenced. The analysis of variance of the crude protein (CP) content, showed that there were no significant differences both between the treatments with CV: 5.29%, as well as with the NDF content between the treatments with 2.81% (CV). La investigación tuvo como objetivo evaluar el efecto de la fertilización química y corrección del pH del suelo, sobre el rendimiento por hectárea y la composición bromatológica del genero Brachiaria, especie Brachiaria brizantha cv brs Piatã, sometidos a cuatro tratamientos y evaluados en tiempos iguales de corte, simulando un pastoreo rotativo. El mismo fue llevado a cabo en la ciudad de San Lorenzo, Paraguay. Los cortes se realizaron cada 35 días después de la siembra, ajustando el pH más la fertilización de acuerdo a las recomendaciones técnicas, dispuestas en 4 tratamientos por bloque: T1 testigo sin aplicación de fertilizantes ni corrección del pH, T2 corrección de pH sin fertilizantes, T3 corrección del pH y aplicación de fertilizantes y T4 fertilización sin corrección de pH. En el rendimiento de materia verde, según el análisis de varianza (ANAVA) que fue aplicado al promedio obtenido de cada corte según los tratamientos, siguiendo el modelo estadístico bloques al azar, arrojó diferencias significativas con un nivel de confianza del 95% y aplicando el test Tuckey para comparación de medias (p<0,05) a favor del T3 con relación a los demás tratamientos. Sobre la composición bromatológica, en cuanto al porcentaje de materia seca se evidenciaron diferencias estadísticas significativas entre tratamientos. El analisis de varianza del contenido de proteina bruta (PB), demostro que no existieron diferencias significativas tanto entre los tratamientos con CV: 5,29%, asi como con el contenido de FDN entre los tratamientos con 2,81% (CV).
