WASHINGTON — Jon Doggett has been named interim chief executive officer of the National Corn Growers Association (N.C.G.A.). Mr. Doggett, currently executive vice-president, will begin his new role Aug. 1, upon the departure of Chris Novak.

Mr. Doggett has served as executive vice-president since 2014. Prior to that, he was vice-president of public policy, and continues to manage the organization’s 11-person Washington office and lead its public policy efforts.

Before joining the N.C.G.A., Mr. Doggett spent 11 years at the American Farm Bureau Federation, where he was the Bureau’s lead lobbyist on a number of public policy issues, including ethanol, climate change, land use, conservation, and endangered species.

While in Washington, Mr. Doggett also worked for the National Cattleman’s Beef Association/Public Lands Council and was senior legislative assistant for former Montana Congressman Ron Marlenee.

The N.C.G.A. said it plans to initiate a formal search process for a permanent c.e.o. at a later date.
