1. Variable Seeding Rate in Sweet Sorghum
By Jake Linneman

2. Facts Corn like in appearance
Requires less water and nutrients then corn
Can be harvested for both grain and sugar content from the stalk

3. The Grain The grain is primarily used for livestock feed
Either cut for silage or the seed is feed like corn

4. The Sugar
The sugar content has been to show great popularity as a biofuel feedstock.
Fits as a rotational crop for Oklahoma growers

5. The juice is what we want from the stalk.
From this juice, the sugar is fermented to produce ethanol.
The ethanol produced from sorghum requires much less inputs than corn.
Can be grown in much more arid climates.
One acre can produce gallons of ethanol.

6. Seeding Rate ~24,000 seeds per pound An average of 3-4 pounds per acre
Dryland
40,000 to 70,000 plants per acre
Irrigated
60,000 to 90,000 plants per acre

7. Planting density and row spacing
Rates
30k, 40k, 50k, 60k, 70k
7.5 inch and 30 inch
Spacing
7.5 inch, 15 inch, 30 inch
50,000 seeds per acre is the constant

8. Harvest
Harvest takes place in the field using an on site juice extractor.
Bladders are in the field to store the juice to which the yeast is added.
