Use of a model to optimize the interaction between frequency and severity of intermittent defoliation and to provide a fundamental comparison of the continuous and intermittent defoliation of grass

Grass and Forage Science, 1988
AbstractA previously described model of grass growth was used to analyse the effect of the severity of defoliation and the duration of the subsequent regrowth on the overall balance between photosynthesis, gross tissue production and leaf death and so on the amount that could be harvested/consumed per hectare under intermittent defoliation.

Frequency and severity of defoliation of grass and clover by sheep at different stocking rates

Grass and Forage Science, 1982
AbstractThe frequency and severity of defoliation of individual grass tillers and clover plant units was studied in Lolium perenne‐Trifolium repens swards grazed by sheep at stocking rates ranging from 25 to 55 sheep ha‐1 and either receiving no N fertilizer or 200 kg N ha‐1.
