Yes. Agree with all of the above. Would like to add it was part of the Cooperative Extension program, as a product of land grant colleges. Every state has has a land grant college. They specialize in agriculture and Home Economics, or used to. Many have dropped some programs for urban horticulture.
Extension service was very big during the depression(the 1939 one) helping farm women cook more cheaply and efficiently. and farmers to produce more and use the land better and repair it.
When i was growing up it was mostly a country thing. An Extension home Economist came to our meetings regularly. I remember my mother going to ladies meetings.
