Drought sensitivity could reduce corn yields for years to come

Corn yields could fall 15 to 30 percent—unless new varieties or agronomic techniques can offset the trend.

Corn plants in the United States have become more drought sensitive, not less.  Yields have continued to increase because seed companies have developed genetic improvements allowing higher planting density.  Drought sensitivity could drive yields down in the years to come unless companies like Monsanto, Syngenta, and DuPont successfully develop varieties that thrive in drought reported the National Geographic.
