Fig. 3. (a) Percent contribution to the pasture from white clover according to harvested herbage, total herbage, ground cover, and tiller/leaf density estimates over spring, summer, and autumn dates from 1998 to 2000. a, b indicate methods that differed significantly (P < 0.05) among seasons. Seasons within methods with the same letter were not significantly different at P < 0.05. (b) Percent contribution to the pasture from other species (including tall legumes) according to harvested herbage, total herbage, ground cover, and tiller/leaf density estimates over spring, summer, and autumn dates from 1998 to 2000. a, b indicate methods that differed significantly (P < 0.05) among seasons. Seasons within methods with the same letter were not significantly different at P < 0.05.
