Cool seeing the results of the experiment. Planting sunflowers, squash, and beans together works really well. The beans climb the sunflowers and the squash shade the soil.
I've been dumping so much grain in my sheep pen and it gets mixed with their poo from them standing in it eating so next year I am going to close the area off and put my pumpkins and winter squash in there. I hope to finally get a 100+lb pumpkin.
