Events like the September 2000 discovery of biologically engineered corn in fast food tortillas have focused media attention and stirred controversy about genetically modified organisms. While new approaches in agricultural biotechnology have improved crop quality and yield, the incorporation of genes from other organisms into food plants has raised concerns about possible health risks and environmental consequences. A new report from the American Academy of Microbiology (AAM) looks at the case of a

Canned corn may be healthier for you than corn on the cob, according to a study by Cornell University scientists. The researchers say that heat processing of sweet corn significantly raises the level of naturally occurring compounds that help fight disease.
The findings are reported in the August 14 issue of the Journal of Agricultural and Food Chemistry, a peer-reviewed publication of the American Chemical Society, the world’s largest scientific society.

Sweet corn is the number-

Cornell University potato breeders are donating a disease-resistant potato to Russia in an effort to help combat aggressive strains of potato late blight that are threatening to devastate the nation’s essential small farms.

The Cornell-developed New York 121 potato, which also is able to fend off golden nematodes, scab and potato virus Y (PVY), will be given to Dokagene Technologies, a company specializing in producing pathogen-free seed in Russia, in a meeting and a field trip in Mosc

Corn, the preferred staple crop in many countries, requires large amounts of nitrogen for its growth. Usually fertilizer is necessary to sustain good yields. A Penn State graduate student, Ylva Besmer, is trying to find ways to improve corn yield for subsistence farmers in Zimbabwe without fertilizer.

“The government of Zimbabwe no longer provides a subsidy for fertilizer, resulting in significantly lower corn yields” says Besmer, a doctoral candidate in ecology. “The old-fashion use of legu

Luckily for us, the economically devastating Karnal bunt fungus needs personal ads and singles bars more than we do.

Airborne spores from the fungus, which damages wheat crops, are limited in how well they can start new infections over long distances, according to the findings from a Kansas State University project.

A phenomenon known as the Allee effect occurs when a small population of a species spread over a large area has little success in reproduction. The reason is that when

New farm practices and new breeds of crops might someday add to mankind’s toolbox for controlling greenhouse gases that contribute to global climate change.

Research under way at Purdue University seeks to control the most prominent of these greenhouse gases, carbon dioxide, by corralling carbon on the farm in a process known as carbon sequestration.

The research is being supported with a grant of nearly $1 million to Purdue from the Consortium for Agricultural Soil Mitigation
