Fig. 5. Sulla crude protein concentration (CP) as a function of mean stage by weight (MSW) at two sites over 3 yr: (a) Ancona ‘Grimaldi’, (b) Ancona ‘Sparacia’, and (c) Sassari Grimaldi. Regression equations of the pooled data:

(a) CP_{Grimaldi 96} (g kg^-1 DM) = -15.7MSW + 274 r² = 0.94 RMSE = 9

CP_{Grimaldi 97} (g kg^-1 DM) = -10.3MSW + 211 r² = 0.80 RMSE = 15

CP_{Grimaldi 98} (g kg^-1 DM) = -18.0MSW + 271 r² = 0.73 RMSE = 20

(b) CP_{Sparacia 96} (g kg^-1 DM) = -17.9MSW + 308 r² = 0.88 RMSE = 14

CP_{Sparacia 97} (g kg^-1 DM) = -10.5MSW + 221 r² = 0.83 RMSE = 14

CP_{Sparacia 98} (g kg^-1 DM) = -21.8MSW + 318 r² = 0.68 RMSE = 26

(c) CP_{Sassari 96-98} (g kg^-1 DM) = -8.57MSW + 191 r² = 0.57 RMSE = 15
