description |
An study was conducted under field conditions at the Truipaná Experimental Station, located in Cereté, Córdoba, at 13 meters of elevation with a -nean temperature of 28°C and an average annual precipitation of 1,112 mm, with the following objetives: To determine the tii."t of different levels of P and K on the forage production of angletongrass (Dichanthium aristatum (Poir) Hubbard), napiergrass (Pennisetum purpureum Schumach), guineagrass (Panicum maximum Jacq.), pangolagrass (Digitaria decumbens Stent), and paragrass (Brachiaria mutica (Forsk) Stapf). To study me frecuency of application of these elements to obtain a constant and high yield of forage. The soil was a clay loam with pH 6,7. Three levels of P2 05and K2 0: 0, 50 and 100 kg/Ha were applied initially. Nitrogen, 50 kg/Ha was uniformly applied after each harvest. The results obtained in this study indicated that P and K applications did not have a significative effect on forage production of all the grasses studied except for napiergrass. Phosphorus (P2 05 ) levels of 50 and 100 kg/Ha had significative effects on the increment of forage production by napiergrass. The application of high levels of both P and K had depressive effects on forage production of angletongrass and guineagrass, and the K on napiergrass. A positive and highly significative interaction was found between P and K for angletongrass and guineagrass. For napiergrass the interaction between P and K was significant and positive for the levels of 100 kg/Ha of P2 05and 50 kg/Ha of K2 0. In contrast, the interaction between K and P was significative and negative for the levels of 100 kg/Ha of K2 0 and 50 kg/Ha of P2 05 . The grasses studied have different requirements of P and K, being the requirements of these elements for napiergrass higher than for the other species included in this study. The forage yield of angletongrass, guineagrass, pangolagrass and paragrass is not increased due to the addition of P and K for a period of three years after planting the grasses. Napiergrass yield, in contrast, can be increased applying 50 kg/Ha of P2 05 two years after the establishment of the pastures on the soils of the Turipaná Experimental Station. |

Determinar el efecto de diferentes dosis de P y K sobre la producción de forraje de los pastos angleton, elefante, guinea, pangola y pará, y averiguar con qué frecuencia se debe aplicar dichos elementos para obtener una producción alta y constante de forraje. Para el presente estudio se utilizó un suelo franco arcilloso con un pH de 6,7. Se compararon tres dosis de P2 05y K2 0: 0, 50 y 100 kg/Ha aplicados después de un primer corte para uniformar. Además se aplicó N uniformemente en dosis de 50 kg/Ha después de cada corte. El diseño utilizado fue de bloques al azar con cuatro repeticiones. Del análisis de los resultados obtenidos es posible concluir lo siguiente: - No se obtuvieron diferencias estadísticas significativas con la aplicación de P y K sobre la producción de forraje de los pastos ángleton, guinea, pangola y pará. - El pasto elefante respondió significativamente a la aplicación de P en dosis de 50 y 100 kg/Ha de P2 05en ausencia y presencia de K, respectivamente. - La aplicación de P y K tuvo efecto depresivo sobre la producción de forraje de los pastos angleton y guinea, y el K sobre el elefante. - En los pastos ángleton y guinea se encontró una interacción P x K altamente significativa y positiva. - Para el elefante hubo una interacción K x P significativa y negativa con las dosis de 100 kg/Ha de K2 0 y 50 kg/Ha de P2 05 , y una interacción P x K significativa y positiva para las dosis de 100 kg/Ha de P205y 50 kg/Ha de K2 0. - Hubo una interacción P x K significativa y negativa para el pasto pará. - Los diferentes pastos estudiados varían en sus requerimientos de P y K, siendo más exigente el pasto elefante. - Para los pastos ángleton, guinea, pangola y pará como únicos componentes de la pradera, no se justifica aplicar P y K en los suelos de Turipaná durante los tres años después del establecimiento, ya que el aumento de los rendimientos debido a estos nutrimentos es bajo. - Para obtener una producción adecuada de forraje con el pasto elefante, es necesario aplicar 50 kg/Ha de P2 05dos años después de establecido.application/pdf-1spaInstituto Colombiano AgropecuarioBogotá (Colombia)Attribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Acceso a texto completohttp://purl.org/coar/access_right/c_abf2Revista ICA;
