Welome Justin, fellow Nebraskan. It sounds like a good area for a plot. What is your rainfall averages for spring through Sept.? I know its more arid in your area of the state than mine but if you can get water from the creek your plot should always do well and will be a good source of water for your fruit trees. Your food plot mix would be best planted in mid to late July, even into Aug for you to realize the benefit of all seeds in the mix.
How big of a plot are you going to plant?
I have planted many apple and pear trees over the past ten years. My experience on the two farms I have put them on is that the deer prefer pears over apples by a wide margin. The pears produce as fast if not faster than apples and produce more, sometimes to a detriment of the tree. Pears are less maintenance by a long ways as well. Almost a plant them, protect them, prune them just enough to keep branches from growing into each other and you're set.
I have many pear and apple trees planted in clover plots and it makes a great combo draw, especially the pears, am I overstating that:}
Turkey Creek nursery is out your way and I have planted many of their trees. Chris is the owner and will be of great help to you if you have questions.
