Fig. 4. Instantaneous growth rates (IGRs) of swards from 1995 through 1997 derived from the Gompertz growth model of cumulative yield as influenced by defoliation frequency. 2WK, clipped at 2-wk intervals to a 5-cm residue; S50, 10-cm canopy clipped to 5-cm residue; T75, 20-cm canopy clipped to a 5-cm residue; 6WK, clipped at 6-wk intervals to a 5-cm residue.
