Two experiments are described which were carried out a) to determine the effect of constant and varying canopy height in a continuously grazed grass/white clover sward on clover development, and b) to investigate the changes which take place in clover contribution to a mixed sward as the canopy develops during regrowth with and without nitrogenous fertilizer under a silage regime. The grazing experiment showed that tiller density was more sensitive to canopy height, achieved by variable continuous grazing by steers, than was stolon density, although production per stolon was lower in the shortest sward. However, when sward heights were adjusted to 7 or 9 cm in autumn the taller sward had the lower stolon density but that was only significant in the following spring
