“…The first has been the evaluation of alternative pasture species that may have drought resistant characteristics (barker et al 1993;Korte & Rhodes 1993;Fraser et al 1999). These include grasses such as cocksfoot (Dactylis glomerata) as assessed by barker et al (1999), or legumes (macfarlane & Sheath 1984).…”

Aseries of trials was established in 2000, and measured until 2002, down the east coast of New Zealand on seven farms with contrasting amounts of spring-summer rainfall and resultant pasture growth. The aim was to evaluate the pattern of pasture responses to a range of nitrogen (N) fertiliser rates and associated soil phosphorus (P) levels generated by a range of P fertiliser treatments. Small plots excluded from grazing were established on steep (about 20 degrees slope) sites containing pastures that had been established for many years. Each of these steep sites was located within a hill paddock containing similar areas with a wide variety of slopes ranging from near flat to steep. Pasture production was measured approximately monthly (less frequently in seasons of slower growth), and soil was sampled for soil Olsen P test in mid spring each year. 90 kg N ha -1 ) were measured from three northern sites, whereas lower responses were recorded at the southern sites, and especially at Moeraki (3.7 kg DM kg -1 N applied). This may be partly explained by the lower temperatures in early spring at those sites. There was no pasture response over the late spring-autumn period in the North Island. However responses were measured at Moeraki in the South Island. There was little change in the average pasture response (kg DM kg -1 N fertiliser applied) to N fertiliser applied at 30 kg N ha -1 and at 90 kg N ha -1 at each site. This was in contrast to responses measured at the same locations on more gentle sloping sites where the average response declined as the rate of fertiliser N applied increased. Pasture responses in early spring to increase in soil Olsen P test were most pronounced on sites such as Wairoa and Wairarapa, with higher than average pasture clover content, and in years where the clover component was greatest. Some pasture responses to increase in soil Olsen P test also occurred over the late spring-autumn period, generally where there was significant clover content. Conclusions from these trials, together with those earlier reported, show that the initial grass:clover composition of the pasture, whether on easy or steep slopes, was able to be modified by both N fertiliser application, and by increasing soil Olsen P test, and was also a determining factor in the responses measured.

“…The greater rate of tiller production in Wana and Matua than in Maru is also reported by Barker & Dymock (1993) in North Island hill country. When drilled into dry hill country close to this site, Archie & Vartha (1985) found that the production of Maru relative to Nui and Matua increased over a 3-year period.…”

Three trials to evaluate new grass cultivars, were attempted on a north-facing aspect in North Canterbury, New Zealand, between late March 1980 and early May 1982. The difficulty of establishing new pastures in this steep dry hill country resulted in the failure of the first two trials. The third trial used spaced transplants to evaluate 'Grasslands .Wana' cocks foot (Dactylis glomerata L.), 'Grasslands Maru' phalaris (Phalaris aquatica L.), and 'Grasslands Matua' prairie grass (Bromus willdenowii Kunth). Wana was the most productive, Matua was intermediate, and Maru phalaris was the least productive. Survival was poor, however, and the role of new pastures in improving this extremely dry hill country must take second place to grazing management.

“…Además, la restricción hídrica reduce la asimilación de carbono y afecta la eficiencia de utilización de nutrientes, siendo el primer factor limitante en la producción de forrajes (Akmal y Janssens, 2004). La limitada precipitación durante el periodo de establecimiento pudo afectar la respuesta en producción de los raigrás evaluados, aunque las producciones de MS fueron similares a las reportadas por Smit et al (2005) y Cuesta (2008, pero menores a las reportadas por Barker et al (1993).…”

ResumenLos sistemas de lechería en Colombia se basan en el uso de praderas, por lo cual es necesario determinar la respuesta de los forrajes bajo diferentes condiciones ambientales. El objetivo del presente trabajo fue evaluar el establecimiento y la producción de raigrás perennes y tréboles en dos regiones del trópico alto colombiano. Se evaluaron cinco raigrás perennes (tres diploides y dos tetraploides) y tres tréboles (dos rojos y uno blanco) en Tuta, Boyacá y Mosquera, Cundinamarca. Se establecieron parcelas de 8 m 2 de cada especie con tres repeticiones. Las variables de establecimiento fueron evaluadas quincenalmente durante los primeros cinco meses. Las variables de producción y calidad nutricional fueron evaluadas en temporada de lluvia (abril y mayo) y de sequía (junio y julio). Se utilizó un diseño de bloques completos al azar con medidas repetidas, entre noviembre de 2015 y julio de 2016. Durante el periodo de establecimiento, se encontró una mayor cobertura y grado de adaptación en los raigrás y tréboles entre los días 45 y 60 y 105 y 150 en Tuta y Mosquera, respectivamente. La mayor edad provocó una disminución en la energía neta de lactancia (entre 7 y 15%) y un aumento en la producción diaria de materia seca por hectárea (entre 20 y 78 kg). El día de evaluación presentó una mayor influencia respecto a la variedad y la época de lluvias sobre las variables de establecimiento y producción evaluadas en raigrás y tréboles en trópico alto colombiano.Palabras clave: ganado de leche, sistema agropastoril, plantas forrajeras. AbstractColombian dairy systems are based on grasslands; therefore, it is necessary to define forages response under different environmental conditions. The objective of this study was to assess the establishment and production of five perennial ryegrass and three clovers into two regions of Colombian highlands (Tuta, Boyacá and Mosquera, Cundinamarca). Three 8 m 2 plots of each species were established. Establishment variables were evaluated twice a
