An El Niño would help U.S. crop production, but could negatively impact worldwide production, a senior agricultural economist says. "El Niño is generally favorable to crop production in the United States because it brings extra rain and moisture into the core crop-growing areas," he said. "We're just coming out of a four-year drought cycle in the United States and we'd like to get back to what we call trend-line yields and big crop production so there's plenty for everybody."
