In the song, "the farmer takes his wife." However, her place on the farm is just as essential as his. "When a farmer buys a cow he looks at her long and carefully, goes over her point by point and weighs his pocketbook against her virtues and her faults. He should be no less calculating when he takes a wife. A young farmer should keep in mind that he will rise or fall on his choice of a wife." - R.J. McGinnis
According to the NPR article, however, this is all changing. While most female agriculturists run small operations, nearly 2,000 have been listed with sales of $1 million or more.
Merriam-Webster defines the glass ceiling as "an intangible barrier within a hierarchy that prevents women or minorities from obtaining upper-level positions." I can only hope that the world will someday see the agricultural glass ceiling shatter.
