Seeding Rate For Soybeans
Seeding rates from 150,000 plants to 225,000 plants per acre do not change soybean yields in North Dakota. However, higher seeding rates, (about 180,000-200,000); are suggested for narrow rows, (12 inches); compared to wider rows, (24 to 30 inches). Fewer seeds per foot of row in narrow rows may have more difficulty emerging than wider rows if soil crusts should occur. Planting more seed may help overcome emergence problems. Soybean seed lots vary in number of seeds per pound. Seeding rate should also be adjusted for percent germination.
For example: 180,000 desired plants Divided By % Germ (.90) and then divided by 3,000 seeds per lb. Equals Seeding rate (67 lbs. per Acre)
