How much sorghum do you plant per acre?
The optimum seeding rate for grain sorghum is about 10 pounds of seed per acre assuming a seed size of 14,000 seeds per pound and 70 percent emergence. Seed size varies from about 13,000 to 16,000 seeds/pound depending on the hybrid.
How much does it cost to plant an acre of sorghum?
“Seed costs for sorghum are $12 to $15 per acre compared with seed corn costs that are often over $100 per acre,” says Staggenborg. Still, sorghum needs inputs like nitrogen (N). The ratio of N needed to produce a bushel of grain is akin to corn’s 1.2 pounds of N per bushel, says Staggenborg.
Does sorghum need irrigation?
Grain sorghum appears to very responsive to deficit irrigation; applying water at critical growth stage to avoid stress, but limiting available water to as low as 60% of the seasonal requirement. Grain Yield was highest at 14 plant/m or 5.3 cm inter plant spacing, under full irrigation.
How long does it take for sorghum to mature?
Keep in mind that how fast a sorghum plant develops is directly related to daily temperature or heat units. Early planting can increase the number of days for sorghum to reach flowering anywhere from 7-25 days, depending on weather conditions and, to a lesser extent, the specific hybrid.
How deep do you plant sorghum?
Sorghum should be planted one inch deep under most situations. Seeds should be placed to moisture, but no deeper than about one inch in heavy soils and about two inches in sandy soils.
Is sorghum hard to grow?
Like corn, sorghum needs ground that gets full sun and has fertile, well-drained soil. Because sorghum is self-fertile, a large plot is not needed for pollination purposes. Sorghum needs soil temperature to reach at least 60°F. In the garden, plant sorghum by hand, 1½ inches deep, in clumps of four seeds per hole.

How much sun does sorghum need?
Like corn, sorghum needs ground that gets full sun and has fertile, well-drained soil. Because sorghum is self-fertile, a large plot is not needed for pollination purposes. Mix a balanced fertilizer into the bed or row before planting. Sorghum needs soil temperature to reach at least 60°F.
