CROP QUALITY & UTILIZATION Seed Production of White Clover Cultivars and Naturalized Populations when Grown in a Pasture
tion, pest or disease resistance, or reseeding ability (Harris, 1987; Brink et al., 1999). Widdup et al. (1996) found Small-type white clover, Trifolium repens L., plants predominate that only 10 of 98 ecotype collections from throughout in most closely grazed pastures in the southeastern USA. The role of relative seed production in stand persistence of white clover types the eastern USA were l...
متن کاملInterannual variation in nitrous oxide emissions from perennial ryegrass/white clover grassland used for dairy production
Nitrous oxide (N2 O) emissions are subject to intra- and interannual variation due to changes in weather and management. This creates significant uncertainties when quantifying estimates of annual N2 O emissions from grazed grasslands. Despite these uncertainties, the majority of studies are short-term in nature (<1 year) and as a consequence, there is a lack of data on interannual variation in...
متن کاملWhite Clover Content in New Zealand Dairy Pastures Affects Milksolids Production
As a preliminary experiment to measuring milksolids (fat plus protein) production of dairy cattle grazing swards containing different levels of white clover (Trifolium repens L.) nine Jersey and nine Friesian cattle housed indoors during late lactation and fed diets containing either 20, 50 or 80% white clover with the balance perennial ryegrass (Lolium perenne L.). During the first 10 day meas...
متن کاملWhite Clover Morphology Changes with Stress Treatments
white clover is positively correlated with increased size of plant parts and reduced leaf density per unit area The plasticity of white clover (Trifolium repens L.) results in (Beinhart et al., 1963). changes in plant habit in response to different environmental stresses. The objective of this research was to characterize those morphological Defoliation through grazing or clipping is a managech...
متن کاملPerformance of nematode-resistant white clover in field trials
Breeding for improved resistance and tolerance to the clover root-knot nematode, Meloidogyne trifoliophila, and the clover cyst nematode, Heterodera trifolii , has been successful in white c lover, Trifolium repens. White clover lines developed from three independent breeding programmes were established in field trials at Lincoln, Palmerston North, Cambridge and Kerikeri. Plants were establishe...
