| description | The aim of this work was to show the relationship of the productivity of a pasture and grassland, the living and dead material, and the foliar elongation of wheatgrass with the soil moisture and the thermal sum in Southern Patagonia (Argentina). During the years 2015/16 (Year 1) and 2016/17 (Year 2), in closures excluded from grazing, the plant height, the accumulated aerial biomass (AAB) and the daily growth rate (DGR) of a mixed pasture and grassland were determined monthly from October to February. The forage harvested from the pasture was characterized in live (LM) and dead material (DM), and the live AAB was calculated. In selected wheatgrass plants, the leaf elongation rate (LER) was determined. Soil moisture (SM) was measured and the thermal sum (TS) was calculated. The AAB was analyzed using a factorial arrangement in a completely randomized design. The results were subjected to ANVA with repeated measures analysis and the means were adjusted with the Tukey-Kramer test. DGR, LM, and LER were related to SM and TS by multiple regression analysis. In both Year 1 and Year 2 and same months the AAB of the pasture exceeded the forage accumulated by the grassland. The LM and the LER varied according to the changes in the SM, and the TS explained the variations of the parameters described, which should be considered when developing future management strategies in this type of pasture. |

Se planteó un estudio con el objetivo de relacionar la productividad de una pastura introducida y el pastizal natural, el material vivo y muerto, y la elongación foliar de agropiros con la humedad del suelo y la suma térmica en la Patagonia austral (Argentina). Durante los años 2015/16 (Año 1) y 2016/17 (Año 2), en clausuras excluidas al pastoreo se determinó mensualmente, desde octubre a febrero, la altura de plantas, la biomasa aérea acumulada (BAAc) y la tasa de crecimiento diario (TCD) de una pastura mezcla de agropiros y un pastizal de gramíneas. El forraje cosechado de la pastura fue caracterizado en material vivo (MV) y muerto (MM), y calculada la BAAc viva. En plantas de agropiro seleccionadas se determinó la tasa de elongación foliar (TEF). Se midió la humedad del suelo (HS) y se calculó la suma térmica (ST). La BAAc fue analizada mediante un arreglo factorial en un diseño completamente aleatorizado. Los resultados fueron sometidos a ANVA con análisis de medidas repetidas y las medias se ajustaron con la prueba TukeyKramer. La TCD, el MV y la TEF fueron relacionados con la HS y la ST mediante análisis de regresión múltiple. En los Años 1 y 2 y los mismos meses, la BAAc de la pastura superó el forraje acumulado por el pastizal. El MV y la TEF variaron conforme los cambios en la HS, y la ST explicó las variaciones de los parámetros descriptos, lo que debiera considerarse al elaborar futuras estrategias de manejo en este tipo de pasturas. Foi proposto um estudo com o objetivo de relacionar a produtividade de uma pastagem introduzida e do pasto natural, o material vivo e morto e o alongamento foliar dos agropyros com a umidade do solo e a soma térmica no Sul da Patagô-nia (Argentina). Durante os anos de 2015/16 (Ano 1) e 2016/17 (Ano 2), em fechamentos excluídos do pastejo, a altura das plantas, a biomassa aérea acumulada (BAAc) e a taxa de crescimento diária (TCD) de uma pastagem mista de agropyros e um pasto de grama foram determinadas mensalmente de outubro a fevereiro. A forragem colhida da pasta-gem foi caracterizada em material vivo (MV) e morto (MM) e calculado o BAAc viva. Em plantas de agropyro seleciona-das, a taxa de alongamento da folha (TAF) foi determinada. A umidade do solo (US) foi medida e a soma térmica (ST) foi calculada. O BAAc foi analisado em arranjo fatorial em un desenho completamente randomizado. Os resultados foram submetidos à ANVA com análise de medição repetida e os mejos foram ajustadas com o teste Tukey-Kramer. TCD, MV e TAF foram relacionados a H e ST por análise de regressão múltipla. Nos anos 1 e 2 e nos mesmos meses, o BAAc da pastagem excedeu a forragem acumulada pelo pasto natural. O MV e o TAF variaram de acordo com as mudanças no US e o ST explicaram as variações dos parâmetros descritos, que devem ser considerados no desenvol-vimento de futuras estratégias de manejo neste tipo de pastagems.
