Fig. 1. Comparisons of quadratic relationships of dry matter loss regressed on rainfall amount for bermudagrass and orchardgrass forages at near-ideal moisture concentration for baling (153 and 130 g kg1, respectively). Quadratic equations for these regressions were Y = 0.0081X2 + 0.83X + 0.49 (R2 = 0.918; P = 0.007) for bermudagrass and Y = 0.018X2 + 2.39X + 10.29 (R2 = 0.894; P = 0.011) for orchardgrass.
