Dry beans plant population
- Typical range: 70,000 to 110,000 plants per acre
- Example spacing: 30-inch rows with 4 plants per foot
- Reference weight of 1,000 seeds: 350 g
In 30-inch rows with 4 plants per foot you get about 69,700 plants per acre. With 85 % germination and seed weighing 350 g per 1,000 (about 1,300 seeds per pound), that is roughly 63 pounds of seed per acre.
Seed size varies widely between market classes, from small black and navy beans to large kidney beans, so the pounds of seed per acre can range from 40 to more than 100.
These are reference values and change with variety, management and region. For your field, check the seed company recommendation or your local extension service.
