  2. Where did this photo come from? • Is there a soybean field close to your school? • Add it here!

  3. What are soybeans? • Soybeans are a row crop (a crop grown in rows) • They are theworld’s leading provider of protein and oil.

  4. Soybeans facts • Soybeans make up 27% of U.S. crop acreage, 2nd only to corn • Ohio planted 4.5 million acres and produced 222 million bushels of soybeans in 2009 • How many bushels per acre does that equal?

  5. Why do we care about soybeans? • They are used in a variety of food products (vegetable oil, lecithin, tofu, soy sauce, etc.) and for consumer products (paints and inks), fuel, industry (polymers, lubricants), and other applications.

  6. How are they grown? • Soybeans are usually planted in May • They have several stages of growth • Vegetative Stages (V-Stages) • VE,VC,V1,V2,V3, Vn • Reproductive Stages (R-Stages) • R1,R2,R3,...R8 • Starts at flowering

  7. What helps soybeans grow? • Proper drainage of water • Sunlight • Few to no weeds • Nutrients-the bacteria help to provide nitrogen, but they need phosphorus, potassium and a variety of other nutrients

  8. How many seeds are planted per acre? • Seeding rates are varied, depending on how the rows are spaced • -generally 125,000-150,000 seeds / acre • Rows can be wide (30 inches apart) or narrow (less than 28 inches apart) • Narrow row spacing has been shown to increase yield, but also increase the need for herbicide

  9. Seeding spacing 15” row spacing (early) 30” row spacing (mid-season)

  10. What do growers do to encourage growth? • Use fertilizers and pesticides • Buy seed varieties that are resistant to SCN and phytothera or even ones that are resistant to the pesticides growers use (Round-Up Ready) • Buy seed treatments that encourage the growth of bacteria (Rhizobia)

  11. What keeps soybeans from growing? • Soybean cyst nematodes - parasitic roundworms that can infect the roots of soybeans, stunting their growth • Phytothera (root rot) - fungus that is encouraged by improper drainage. • Excessive weed growth within or between the rows can take valuable nutrients from the soil
