plant scientists have developed a new strain of pearl millet
that may become an important U.S. grain crop.
Though pearl millet, a grain crop native to western Africa,
is grown in the United States for forage, there is no
established grain market for it. But research undertaken by
geneticist Wayne Hanna and plant pathologist Jeff Wilson of ARS'
Crop Genetics and Breeding Research Unit in Tifton, Georgia, may
help create such a market.
The hot and sometimes arid summers of the southeastern United
States can pose problems for growers of other crops. But pearl
millet, native to the southern fringes of the Sahara Desert,
thrives under these conditions. In Africa, it grows 10 feet tall
and is a difficult crop to handle by U.S. standards.
Hanna and Wilson developed a new strain that grows only 4
feet tall, flowers earlier at 45 to 48 days, and produces higher
yields of grain. The new hybrid can be harvested in 80 days, a
short growing season that can offer flexibility on southeastern
farms, and its compact size allows growers to use standard
planting and harvesting equipment.
The protein- and calcium-rich grain may find a market as part
of commercial poultry diets, which now consist mostly of corn
and soy, with corn being the largest component.
Corn used for feed in large commercial poultry operations in
Georgia and other southeastern states is shipped in from other
states at great expense. Pearl millet may allow farmers in the
region to supply some of the poultry industry's needs,
significantly reducing costs, and at the same time open a new
market for pearl millet.
Pearl millet's use may not be limited to poultry feed. In
Africa, the highly nutritious grain is used mainly for human
consumption. The grain may, in time, find a market in the U.S.
food industry as well.
