Spatiotemporal Genetic Structure within White Clover Populations in Grazed Swards

tion of rare seedling recruitment and clonal growth (Barrett and Silander, 1992; Chapman, 1983; Fothergill White clover (Trifolium repens L.) populations exhibit high genetic et al., 1997; Grime et al., 1988). In addition, somatic and clonal diversity, but often exist for many decades in grazed swards at northern midlatitudes. This study was conducted to determine mutations during vegetative pr...

Linking Management, Environment and Morphogenetic and Structural Components of a Sward for Simulating Tiller Density Dynamics in Bahiagrass (Paspalum notatum)

A model which describes tiller density dynamics in bahiagrass (Paspalum notatum Flügge) swards has been developed. The model incorporates interrelationships between various morphogenetic and structural components of the sward and uses the inverse of the self-thinning rule as the standard relationship between tiller density and tiller weight (a density-size equilibrium) toward which tiller densi...

Water quality implications of nitrate leaching from intensively grazed pasture swards in the northeast US

High density animal production systems, such as management intensive grazing (MIG), can have a negative effect on water quality. Learning to manage such systems to minimize water quality impacts is essential for the environmental and economic sustainability of these types of animal production systems. Management intensive grazing is a grazing system in which animals at a high stocking density a...

Long-term Accumulation of Soil Carbon and Nitrogen in Grazed Bermudagrass Pastures

Ingestive Behaviour of Fistulated and Intact Sheep Grazing Grasses and Legumes Indoors and Outdoors

RESULTS AND DISCUSSION Sward variables did not differ between the indoor grazed turves and the outdoor grazed swards (P>0.05), giving confidence that turves extracted from the plots were representative of in situ swards. Sward height was generally greater for grasses than white clover at the same maturity stage, but bulk density was greater for the clover. Reproductive swards had greater mass b...
