*Double-crop beans should be planted in row widths of 15 inches or closer.
- Based on 85 percent germination (full-season = 176,000 seeds/A; double-crop = 235,000 seeds/A).
- Full-season = 150,000 plants/A; double crop = 200,000 plants/A.
- Full-season, low-risk = 120,000 plants/A target population (see text for explanation).
