Firstly, I'm not a dove hunter. I raise some cows, and have a meadow that I cut hay from. As it has a nearby pond, roost areas, etc, my brother (who does dove hunt) suggested I plant some sunflowers to draw those birds in. So, I am doing this as simple, easy, and cheaply as I can. I have tried to study, but get frustrated with different varieties, pre-emergents, post emergents, and the cost of these things. I have taken my tractor tiller, and tilled some areas along the edges of the hayfield, plus a couple areas I don't generally cut. This will be behind an electric fence, so it won't get eaten down. Total tilled area maybe an acre, but it stretches in 8 ft rows here and there in an area of about 10 acres. I planned to broadcast seed into this well tilled strip, then drag over it. Right now, my plan is to use a pre-emegent that is not horribly expensive, I think Treflan or Prowl, then go ahead and buy the semi-expensive Clearfield seed. I'll fertilize this at the same time are the bermuda hayfield it shares. Now, the confusing part. I believe I'll need a post emergent. For Clearfield seed they recommend using Beyond. Incredibly expensive, and sold only in 2.5 gallons, as far as I can find. There is something called Poast. It seems to be an old timer. I could cheaply spray with that, and it is mentioned for use with sunflowers. Is this a viable plan for this lark of a project?
