Cahokia's rise parallels onset of corn agriculture

Corn cultivation spread from Mesoamerica to what is now the American Southwest by about 4000 B.C., but how and when the crop made it to other parts of North America is still a subject of debate. In a new study, scientists ...

How soil microbes help plants resist disease

Plants can't self-isolate during a disease outbreak, but they can get help from a friend—beneficial soil microbes help plants ward off a wide range of diseases. Now, Texas A&M AgriLife scientists have uncovered a major ...

New tool could help scientists dig deeper for prized crop genes

A new computer application (app) from Agricultural Research Service (ARS) scientists could speed the search for genes that underpin important crop traits, like high yield, seed quality and resistance to pests, disease or ...

Scientists learn how to increase corn crop yields

NSF-funded scientists at Cold Spring Harbor Laboratory are figuring out how to pack more kernels onto a corn cob. One way to boost the productivity of a plant, they say, is to redirect some of its resources away from maintaining ...

Shifting the balance of growth vs. defense boosts crop yield

Cold Spring Harbor Laboratory (CSHL) scientists are figuring out how to pack more kernels onto a corn cob. One way to boost the productivity of a plant, they say, is to redirect some of its resources away from maintaining ...

Consider soil in fall-applied ammonia rates, study says

Fall-applied anhydrous ammonia may not fulfill as much of corn's nitrogen needs as previously assumed. According to a new study from the University of Illinois, the effectiveness of the practice depends on the soil.

How nematodes outsmart the defenses of pests

The western corn rootworm, one of the world's most damaging maize pests, can use plant defense compounds to defend itself against its own natural enemies, so-called entomopathogenic nematodes. However, the nematodes can become ...
