Dry Bean Planting Rates
March 29, 2006

Planting rates vary from 40 to 65 pounds per acre, depending on row spacing, plant type and percent pure live seed. Navy beans range from 2,200 to 2,500 seeds per pound. Planting rates suggested for navy beans are 40 to 45 pounds per acre of pure live seed. Studies conducted at various plant populations do not indicate any significant advantage to having populations greater than 90,000 plants per acre for Type I navy beans. Slightly higher planting rates are advised under irrigation.

Pinto beans range from 1,200 to 1,500 seeds per pound. Planting rates suggested for pints are 50 to 65 pounds per acre of pure live seed. Populations of 70,000 plants per acre for Type III (Pinto) beans have been found to be adequate. In some instances, reduced yields were observed when plant populations were below these recommendations. Under irrigation, some lodging has been observed in the Type I cultivars at extremely low plant populations. No relationship between spacing and plant population was found in studies conducted in
North Dakota.

Rates should be adjusted for low germination or cool, wet planting conditions. To obtain desired plant populations, overseed live seed by 10 to 15 percent to compensate for losses during emergence. The normal planting depth is about 2-2 1/2 inches. Seed should not be planted deeper unless the topsoil is dry. Plant seeds in moist soil if possible. Windbreaks of corn or sunflower can be planted in fields where winds could become at harvest. Growers should test their planter on a hard surface and in the field at normal planting speeds to ensure proper depth and seeding rate.
