Stellar genetics and favourable weather are boosting corn yields to unheard of levels this harvest season in the United States, agronomists and grains analysts said on Thursday.
"Yields this year are phenomenal, especially in Central Illinois which is a big corn-producing area. We've had adequate weather but nothing fantastic and we have some amazing genetics," said Dennis Bowman, an extension agronomist for the University of Illinois.
Illinois and Iowa annually rank one and two in total corn and soybean production in the United States. Corn and energy traders are beginning to pencil in a mammoth, record large US corn crop for 2007 due to huge corn acreage, overall satisfactory weather and high-tech farm management practices including planting of exotic corn hybrids called triple-stacked or genetically modified organisms (GMOs).
The controversial GMO corn is "not cleared for export but with so much demand now for ethanol they're using it and next year Syngenta is coming out with a quad-stack," Bowman said. Bowman said the triple-stack hybrid seed corn includes built-in protection from corn borer, root worm and a resistance to harm from such potent weed killing chemicals as RoundUp or Liberty. The quad-stack will have resistance to each insect and to Roundup and Liberty, he said.
"If the ethanol market is going to gobble everything up it (GMO) is not quite as big a concern," Bowman said. Farmers planted 92.9 million acres of their farmland to corn this year sharply up from only 78.3 million last year. They increased their corn sowings because corn prices soared to decade-highs due to the surging demand for corn from the energy or ethanol sector.
The US Department of Agriculture (USDA) on October 12 will release its updated forecast for 2007 corn production. Some estimate a record crop exceeding 13.3 billion bushels, beating the record 11.8 billion bushels produced three years ago.
"I'm hearing a lot of yields over 200 bushels per acre, which is just phenomenal and one producer reported 240 bushels per acre," Bowman said. "Average yields around here used to be around 160 to 180 bushels an acre."
The USDA in September forecast the national average corn yield this year at 155.8 bushels per acre. The total 2007 output was pegged at 13.308 billion bushels. "It wasn't the best growing season, yet there is a chance US corn yields will get close to or may exceed the 2004 record," said Dan Basse, president of AgResource Co, Chicago.
