Fig. 2. Aboveground dry biomass (BM, t ha^–1) according to the number of days after sowing. (A) Exp. 3 uncompacted LF Cheyenne, R² = 0.98; (B) Exp. 4 uncompacted LW Dove, R² = 0.99. The points represent the observed values per replicate and the curve is the fitted curve of the beta growth function. BF = beginning of flowering; FSSA = final stage in seed abortion; PM = physiological maturity; BM_max = maximum value of BM; te = time when BM_max is reached; t_m = abscissa of the inflection point at which the growth rate reaches its maximum value; cm = growth rate at tm. An asterisk indicates the parameters that were experimentally determined.
