Is Sorghum a Fit for North Carolina R.W. Heiniger Vernon G. James Center North Carolina State University
The Environment for Grain Sorghum • Increasing Market Opportunities and Potential • Growing Grain Sorghum in North Carolina • Advantages and Drawbacks to Grain Sorghum • 4. The Future for Grain Sorghum
Opportunities in Grain Sorghum • Key Markets are: • Henderson – IAMS plant • Waverly, VA – Feed processing • Raeford, NC – Ethanol (Price per bushel except Sorghum price per cwt.) SRW Wheat 7.69 per bushel Yellow Corn 6.29 per bushel Yellow Sorghum 10.75 per cwt6.02 per bu Yellow Soybeans 13.65 per bushel
Sorghum Production In North Carolina
KEYS TO PROFIT • Sorghum requires careful management Hybrid Selection for Yield and Disease Resistance Planting Date Row Spacing and Seeding Rate Fertility Weed Control Insect and Disease Control
KEY # 1: HYBRID SELECTION • Maturity – Disease Tolerance – Yield: These are the keys to a hybrid that produces high yield in North Carolina. Early - Medium Hybrids Late Hybrids Pioneer 86G08 65 Pioneer 85G46 69 DeKalb DK44 66 DeKalb DKS44-20 70 DeKalb/Asgrow A571 71 DeKalb DKS54-00 72 DeKalb/Asgrow A603 72 DeKalb DKS54-03 72 Pioneer 84G62 72 Pioneer 83G66 72 Pioneer 83G15 73 Pioneer 84G77 71

KEY # 4: WEED CONTROL • Start with Bicep or Harness for good early weed control • Quick Emergence and Early Growth • Combination of Atrazine and
KEY # 5: FERTILITY MANAGEMENT • Current recommendations • 1.5-2 lb N/cwt = 0.84-1.12 lb N/bu • 25% @ plant • +40 lb if silage • Need Good P and K indexes: 60 or better • Crop requires 35 to 40 lbs of phosphorus • Crop requires 50 lbs of potassium

KEY # 6: INSECTS AND DISEASES • Ear worms and birds can cause severe damage • Maize Dwarf Mosaic and anthracnose can be severe with continuous sorghum or following corn • Maturity selection can impact disease and pest avoidance
Corn Earworm Damage
Maize Dwarf Mosaic Virus Anthracnose Stalk Rot
Disease Ratings for Anthracnose Table 1. Anthracnose ratings for sorghum hybrids grown in North Carolina. 1 = poor diseases resistance; 10 = excellent resistance. Maturity refers to the number of days to flowering or mid-bloom.
KEY # 7: EARLY HARVEST • Harvest early - need to have facilities to dry grain • Early harvest avoids: • 1. lodging problems • 2. Grain deterioration • 3. Late tillering that interferes with harvest
Advantages to Sorghum Lower Input Costs Sustainable Returns in Low Yield Environments Better Nutrient Utilization than Corn - Highly Compatible with Swine or Poultry waste applications Excellent Rotation Crop for Cotton or Soybean More Residue Produced Compared to Corn Chemical Weed Control Alternatives for Roundup Resistant Weeds When Harvest Occurs on Time Less Mycotoxins in Grain
Drawbacks to Sorghum Fewer Available Markets Does not have the High Yield Potential of Corn in Better Environments Crop Failure and/or Low Yield can Occur with Little Moisture During Heading Few Options for Post-Emergence Grass Control Anthracnose and Earworms are Critical Threats Less Production Information on Fungicides
The Future of Sorghum Production In North Carolina
What Will it Take to Expand Acres? • Markets that Desire Sorghum • Ethanol – less mycotoxins, marginal land utilization • Feed Grains – Change in Milling Practices • Future Human Food Products?? • Severe Cost Increases in N, P, and K or Lack of Availability • Ideal Crop for Biomass or Carbon Sequestration
Advantages of Sweet Sorghum • Multi-Dimensional Energy Crop – 30 mt per hectare yield • 3 to 4 tons of ethanol from sucrose • 9 to 12 tons of cellulosic ethanol • 6000 cubic meters of methane • Potential for 3 times more energy per hectare than corn and stover and 1.5 times more energy than switchgrass • Ideally suited for marginal soils in the southeastern US – can be grown with modest amount of nutrients • 4.
