View larger version (39K): [in a new window]   Fig. 1 Response surfaces for cauliflower grown during the 1993–1994 season. (A) Predicted marketable yield (Mg ha-1). The shaded area represents 95% of the maximum predicted value. (B) Predicted net return ($1000 ha-1). The shaded area represents 95% of the maximum predicted value. (C) Predicted unaccounted fertilizer N (kg ha-1). The shaded area represents 40 kg ha-1 of unaccounted fertilizer N. (D) Spatial analysis of response surfaces of marketable yield, net return, and unaccounted fertilizer N

The shaded area represents 95% of the maximum predicted value. (B) Predicted net return ($1000 ha-1). The shaded area represents 95% of the maximum predicted value. (C) Predicted unaccounted fertilizer N (kg ha-1). The shaded area represents 40 kg ha-1 of unaccounted fertilizer N. (D) Spatial analysis of response surfaces of marketable yield, net return, and unaccounted fertilizer N. The shaded area represents overlap of zones of 95% maximum predicted marketable yield and net return, and 40 kg ha-1 of unaccounted fertilizer N
