Sugar Beet Seed Spacing

How much land would 10 grams of sugar beet seed cover, and at what spacing?

10 g contains 500-950 seed. The recommended seeding rate is 10-16.5 kg/ha. The rows should be spaced 56cm apart and the plants in the row should be 6-9cm apart. The germination rate is 60-100%. Your 10 g would need about 10 square meters or about 90 square feet.
