Weight of Kochia sedifolia, estimated in September, on plots grazed at different rates of Stocking â Yudnapinna. Actual weights of forage are shown for the ungrazed control plot to indicate seasonal fluctuations. For the grazed plots weights of forage have been adjusted relative to the ungrazed plot to eliminate the direct effects of season, and the mean of the ungrazed plot (broken lines) is shown for comparison. 135.
