Description
Sward structure under continuous (CG) and rotational (RG) grazing system was studied at an experimental pasture in the Jizerské hory mountains. Herbage mass and vertical distribution was assessed by cutting ten quadrats (0.1 x 0.5 m) and separated into grass, white clover, dandelion, other forbs and dead material. The proportions of grasses was higher at RG (on average 51% of the pasture mass) than at CG (41%). In the years with normal amount and distribution of precipitation the proportion of white clover was higher at CG (17%) than at RG (9%). The lack of summer precipitation damaged more significantly the clover at CG than at RG and it reduced its proportion also in spring of the following year. The proportion of other dicotyledons was at both RG and CG similar. The average accumulation of the total pasture mass in the sward layer of 0-30 mm reached 45% at RG and 65% at CG. The average rate of dead material in the pasture mass was higher at CG (26%) than at RG (22%). The differences in sward structure did not have significant influence on the heifer production.
