Gomez & Gomez (1984, p. 143) report a rice experiment with three management practices (minimum, optimum, intensive), five different amounts of nitrogen (N) fertilizer (0, 50, 80, 110, 140 kg/ha), and three varieties (V1, V2, V3). The experiment involved variety and management as qualitative treatment factors and nitrogen fertilizer as a quantitative treatment factor. Overall, there were 45 treatment.
