Welcome to Doniphan County

Picture of the Doniphan County Extension OfficeExtension Programs present useful information related to agriculture, family & consumer science, youth development, family life, business and economics, healthy living, and much more.

Extension Agents and Volunteers take programs to schools, gardens, community centers and other places. Our philosophy is to help people help themselves by taking university knowledge to where people live, work, play, develop, and lead. We work at being responsive to the needs of people by focusing our resources on providing quality information, education and problems solving programs for real concern.

Our office provides educational materials, fact sheets, and pamphlets that are free to the general public through K-State Research and Extension. We can handle any of your agriculture, family and consumer science, and 4-H and youth development questions.
