You farm a lot?
We still save seed for replanting. It is the Monsantos of the industry that has driven the prices of seed up to where 100 bu yields wont pay the costs for raising the crop, and 200 will barely. Dont harp about the farmers, look at Monsanto and Pioneer and those people who drive the price of $3 worth of seed to over $100.
That specially grown seed is the genetic mutations that Monsanto is working so hard to protect. If they get this through, then Monsanto will tell you what you can eat.
I farmed in MN until 1986 when I sold to my share to my brothers.
The only seed we ever saved and planted were soybeans and small grains, and after better soybean seed came out we bought.
We never planted saved corn seed, as the difference was so great. Maybe 30 or 40 bushels for saved seed, 90 to 140 bushels per acre with commercially produced corn seed. I can’t recall anyone ever planting their own corn seed since I can remember back to the 50’s.
