I would recommend growing your corn in a square not a couple of rows to help with the pollination. No matter which way the wind blows it will hit some of the others.

I personally will not bother to grow corn in my garden because it is not worth using up the room for the relatively low yields.

I tried growing Zucchini under corn one year and that sort of failed. The zucchini needs sun and only grew out of the ends of the rows. I still had enough zucchini!

I have known a couple of people that have had Horseradish in a corn field that they claimed worked if you don't spray the corn with weedkiller. Dig what horseradish you need and then plow the corn. The Horseradish roots then replant themselves and it is a continuing thing....
