Description
The effects of combined frequencies and intensities of defoliation were assessed through different sward heights at cutting time and residual stubble heights on a second-year temperate pasture composed of tall fescue (Festuca arundinacea Schreb.), white clover (Trifolium repens L.) and birdsfoot trefoil (Lotus corniculatus). Frequencies of defoliation could only be evaluated in autumn and winter since soil water deficit became especially critical in spring and summer. Main differences in yield within seasons were due to a combination of the intensity of defoliation at which the particular treatment was managed and that of the previous season. Extreme weather conditions characterized by early frosts in autumn and soil water deficit throughout the entire experimental period proved as relevant as management in determining DM yields.
