Description
An experiment was conducted in order to characterise the seasonal distribution of the dry malt er (DM) yield of buff el ( Cenclmis ciliaris), guinea (Panicum maximum) and llanero (Andropogon gayanus) swards under dryland conditions in Yucaufo, Mexico. Average rainfall is 952 mm - falling mainly in June-November. Treatments consisted of a factorial arrangement of grass species, and 3 series of plots rotationally 6 weeks with 2-week intervals between cuts, all allocated to 4 blocks on a Luvisol. Plot size was 3x4 m and the sampling area was 6.9 m2, The cutting height was 20 cm. Fertilisers (NPK) were split and applied after cuttings at a rate of 42, 12.8 and 11.5 kg/ha/ cutting, respectively. Growth rates, 83, 124 and 135 kg DMlha/day, were highest in July for buff el, and in August for guinea and llanero swards. A reduction in growth was then observed, being sharper in llanero and guinea than in buffet, although the lowest rates ln December were similar (6, 9 and 10 kg/ha/day for buffel, g'uinea and llanero). The annual DM yields for guinea and buffel were 15 704 and 10 715 kg/ha (P<0.0001 ), but no differences were found (P>0.05) between guinea and llanero (16 703 kg/ha/year). II was considered that the rainfall distribution and probably the daylength eventually affected the growth rates of the pastures.
