Selecting the correct seeding rate for sorghum based on its seeds per pound By Tracy Neff, Product Development/Genetic Selection, King’s AgriSeeds Inc. Sorghum seed, whether forage sorghum, sorghum sudan or a sudangrass, comes in varying seed size.
Seeding Rates. Grain sorghum seed varies greatly in size (11,000 to 27,000 seeds per pound); however, forage sorghums can have as many as 55,000 to 68,000 seeds per pound. This variability with respect to seed size can have a substantial effect on plant population if planting rates are determined on a seed weight per unit area basis.

3 天之前 · For silage production, the usual procedure is to plant forage sorghum in rows at a seeding rate of 5 to 10 lb/acre. Plants grown in 30 to 40 in. rows usually yield as much as those grown in solid stands, and the lower leaves are retained on the plant longer.
Sorghum can be established in conventional, reduced tillage, or no till cropping systems with drill seeding or broadcasting. Soil temperatures should be between 60– 70°F before planting sorghum. The recommended seeding depth for all sorghums is ¾–1 ¼ inches in heavy soils and up to 2 inches in sandy soils (Undersander, 2003).

Recommended seeding depth for all sorghums is 3 ⁄ 4 to 11 ⁄ 4 inches in heavy soils and up to 2 inches in sands. Seed at the rate of 12-15 lbs/A. Sorghums are normally seeded with a corn planter using 20 to 30-inch row spacing. Sudangrass is usually seeded with a grain drill at 20 to 30 lbs/A using 6 to 7-inch row spacing.

Recommended seeding rate for forage sorghum intended for silage use in Florida is 6–8 lb per acre (R) and 10–15 lb per acre (B). Recommended seeding rate for sorghum x sudan hybrids in Florida is 8–20 lb per acre (R) and 25–30 lb per acre (B).
Seeding rate for marginal dryland at 5–10 kg/Ha and for favourable dryland or irrigation, 10–20 kg/Ha. DISCLAIMER: The information provided in this fact sheet is intended as a guide only and is current as of July 2020.
Sorghum Seeding Rates
The table provides general guidelines for seeding rates based on yield goal. These seeding rates can be adjusted to fit local conditions, but are appropriate under most environments. Some agronomists recommend increasing the seeding rate on narrow rows, for example when switching from a 30-inch row spacing to a 15-inch row spacing. Typically ...
Seeding rates for forage sorghums are similar to those recom-mended for grain sorghum and are relatively high be-cause only 65 to 70 percent of the seeds normally emerge. Rates vary across the state depending on culti-var, rainfall, growing conditions, and intended use of the forage.
