Denhoff,ND right in the center of the State | They are hybrids, cant use your own seed, a bag of seed at 22,000 population and seed size 3 will seed 8 acres and are about $300.00 per bag, This is for a Mycogen, 270 clearfield sunflower, they have three uses, can be used for oil, dehulling for snacks food and for in baking, and also as a birdfood. I like these because I can sell for the one that has the best market. They like NH3, should soil test for actual fertilizer needs. Terry |
