Fig. 2 Pregraze canopy light interception (%) in Florakirk bermudagrass pastures in 1993 and 1994 as affected by length of rest period (RP) and postgraze stubble height (SH). In 1993, pregraze light interception = 22 + 2.48 (RP) + 2.09 (SH) - 0.03 (RP)² - 0.04 (RP x SH); R² = 0.84. In 1994, pregraze light interception = 12.3 + 1.74 (RP) + 4.09 (SH) - 0.05 (SH)² - 0.06 (RP x SH); R² = 0.96
