| Summary, etc |
Durante 3 anos (1975-78) se midio el efecto de 4 niveles de N: 0, 200, 400 y 600 kg/ha/ano, dividido en 5 aplicaciones/ano, en la produccion de carne de Digitaria decumbens. Cada nivel de N se pastoreo en forma continua a 3 cargas escalonadas de 1.3 a 7.1 novillos/ha; se conto con 12 tratamientos dispuestos al azar en 2 bloques. Se usaron novillos de destete, con cambio de animales todos los anos a principios de abril. La ganancia de peso anual/animal se afecto en forma lineal y negativa por la carga (X) en cada nivel de N; las regresiones para Y en kg/animal/ano fueron: Y0 = 224-45.9 X; (1.3 X 2.5); Y200 = 227-30.7 X; (1.8 X 3.8); Y400 = 228-27.8 X; (2.5 X 5.5); Y600 = 207-20.5 X; (3.8 X 7.1). Tambien hubo efecto del ano, resultando las ganancias de peso vivo mayores en el primero: 140, 115 y 118 kg/animal. El efecto medio del N fue negativo en las ganancias diarias invernales: 101, 77, -8 y -78 g/dia/animal para nivel N0, N1, N2 y N3, resp. Las ganancias diarias estivales (sept. a abril) fueron menos afectadas por los tratamientos, siendo la mayor 678 g/dia a 2.5 novillos/ha en el nivel 200 kg de N/ha. La produccion de carne vario entre 217 y 507 kg/ha/ano, aumentando con la carga y el nivel de N. Para esta medida hubo interaccion ano x tratamiento, debido a que en el primer ano hubo una tendencia lineal a aumentar con el nivel de N que cambio a cuadratica en el segundo ano. La eficiencia del N para producir carne fue variable y relativamente baja en los 3 anos. La mayor eficiencia se obtuvo en el segundo ano con 2.5 novillos/ha y fue 1.05 kg de carne/kg de N adicional. La disponibilidad de MS permanecio relativamente constante a baja carga sin aplicacion de N. Los kg de MS disponible prom. por estacion se relacionaron negativamente con la carga y positivamente con el nivel de N aplicado durante todo el periodo del ensayo. (RA) |
