Acacia caven cover on the pasture quality and microclimate in a silvopastoral system of central Chile
The objective of this study was to determine the effect of different tree covers on the productivity and quality of the pasture and on specific microclimatic variables in an Acacia caven-based silvopastoral system. A trial that included four tree-cover treatments (0%, 30% - 40%, 50% - 60% and over 7...

| description | The objective of this study was to determine the effect of different tree covers on the productivity and quality of the pasture and on specific microclimatic variables in an Acacia caven-based silvopastoral system. A trial that included four tree-cover treatments (0%, 30% - 40%, 50% - 60% and over 70%) was established in an experimental set-up with complete randomized blocks and three repetitions. In addition to the productivity and quality of the pasture, probes were used for the continuous measurement of soil temperature and moisture at 15 cm depth, ambient temperature and relative humidity. The period of analysis included two prairie growth seasons. Three models were considered for the statistical analyzes: i) tree cover on pasture productivity; ii) tree cover on microclimatic variables; and iii) the prairie productivity, considering the microclimatic variables as covariables. The results indicate that in the second growing season, the highest productivity was achieved with the tree-less treatment (0% cover). No effect of tree cover on the quality of the prairie was detected, nor on the microclimatic variables in either period. The microclimatic variables that best explained the development of the prairie were the minimum relative humidity and the ambient temperature. After two growing seasons, it is not possible to determine which treatment generates the best conditions for the productivity of the pasture, so it is necessary to continue with the measurements. |

El presente estudio tiene como objetivo determinar el efecto de diferentes coberturas arbóreas sobre productividad y calidad de la pradera y sobre variables microclimáticas, en un sistema silvopastoril con espino (Acacia caven). Para ello se estableció un ensayo con cuatro tratamientos de cobertura arbórea (0%, 30% - 40%, 50% - 60%, > 70%), en un diseño experimental de bloques aleatorizados completos y tres repeticiones. Además de variables relacionadas con la productividad y calidad de la pradera, mediante sensores se realizó la medición permanente de temperatura y humedad de suelo, temperatura ambiente y humedad relativa. El periodo de análisis incluye dos temporadas de crecimiento de la pradera. Para los análisis estadísticos se consideraron tres modelos; i) la cobertura arbórea sobre la productividad de la pradera; ii) la cobertura arbórea sobre las variables microclimáticas y iii) la cobertura arbórea sobre la productividad pratense, considerando las variables microclimáticas como covariables. Los resultados indican que, en la segunda temporada, la mayor productividad se alcanzó con el tratamiento sin presencia de árboles (0%). No se detectó efecto de la cobertura arbórea sobre la calidad de la pradera, ni sobre variables microclimáticas, para los periodos evaluados. Las variables microclimáticas que mejor explicaron el desarrollo de la pradera fueron la humedad relativa mínima y la temperatura ambiente. Transcurridas dos temporadas de crecimiento, no es factible dilucidar aún cuál tratamiento genera las mejores condiciones para la productividad de la pradera, por lo que se hace necesario continuar con las mediciones.
