American farmers have a long history of overcoming obstacles. In 1938, they helped the country emerge from the Dust Bowl by switching to contour plowing and eradicated the boll weevil forty years later by employing integrated pest management techniques.  In both cases – and many others – USDA was there to help farmers achieve success.

Many of the obstacles they face today are on a much larger scale, associated with climate change and seasonal weather variability. USDA’s National Institute of Food and Agriculture (NIFA) is helping farmers get the tools they need to meet those challenges.

Researchers at North Carolina A&T University (NC A&T) are on the verge of leveling the playing field for millions who suffer allergies from peanuts and wheat.  Now, in addition to being able to nosh on some of America’s favorite foods, allergy sufferers may also take advantage of the valuable nutrients these staples provide.

Peanut allergy is one of the most common causes of food-related anaphylaxis and affects about 2.8 million Americans, including 400,000 school-aged children.  Wheat is one of the top eight food allergens in the United States.

That handy chart on the back of seed packets tells backyard gardeners when it’s time to plant based on where they live.  Things get a bit more complicated, however, when your goal is to feed the world.

Researchers at the University of California–Davis have unlocked a long-held secret into how wheat determines when it’s time to flower.  This information is critical to wheat growers because flowering marks the transition between the plant’s growing period and the reproductive stage when the actual grain is created.  Equipped with this knowledge, breeders can develop better adapted varieties to help growers maximize yield.

Good news for those who crave culinary heat.  From the chili pepper aficionados who “eat fire” to those who prefer more subtle flavors, researchers have found a way to help ensure that more of their favorite foods will be available on store shelves.

Scientists at University of California–Davis have identified a candidate gene that encodes natural resistance to Phytophthora capsici, a fungus-like pathogen that causes root rot in peppers.  P. capsici is a major limiting factor to chili production worldwide.

Farming and ranching is not a one-size-fits-all approach. Agriculture in the United States is a mixing bowl of diversity, and it’s most evident when comparing large- and small-scale farming operations. Having grown up on a small, family farm in Iowa, I saw first-hand not only how important our small farmers and ranchers are to the nation, but also the challenges they face daily.

There is much variation among small family farms and ranches. No one definition comes close to capturing the richness and diversity of these operations. For example, while many farmers and ranchers are loyal to their traditional production systems, others constantly seek new opportunities and experiment with alternative crops, production methods and innovative marketing approaches. As a result, the United States produces a striking range of food and fiber, from soybeans to sesame, from beef to buffalo.

They say that variety is the spice of life. Well, you can’t get much more variety than in the plant world. Genetic variation exists for many traits in all crops. For example, although most carrots on grocers’ shelves are orange, carrots can also be white, yellow, green, or purple. Most potatoes are susceptible to potato late blight, but some wild potato species are immune. Carrot color may be unrelated to where the carrots are grown, so a local grower can grow whatever color carrot people enjoy. Variation for disease resistance or tolerance to different soil types, however, does affect local adaptation.

Many local foods can be bred specifically to adapt to local conditions and preferences. Since local breeding takes manpower, the costs for these seeds can spill over to the customers. One solution is participatory plant breeding where breeders and farmers collaborate to contribute genetic variation; resources such as fields and labor; and expertise in breeding, crops, and farming.
