I have some property near Childress so we get about the same amount of rain as you. I had TPW Biologist out a couple of years ago, and the main item they stated was try to avoid specialty seeds like mixtures of clover, wheat, etc. as the lack of rain will hinder their growth. The seeds I would recommend would be wheat and oats in the fall, and sunflowers or millet in the spring. I pick some years to just plant in the fall because it is really hard in dry summers to get anything to grow. Spring/summer plots will be harder to grow because it gets really hot really fast, but I have found sunflowers do pretty good. Yes, deer like sunflowers and you will also get doves and turkey as well as other birds. Your plan for bringing kids is great, and the more wildlife they can watch and see makes being in the outdoors more exciting. No matter what you plant, rain will be key for them to grow, even if it is a little bit. Try to time your planting to have rain/cooler weather within several days after planting. I normally turn the soil in Feb./march and just leave the dirt. You will get weed growth which they like, plant summer seeds in march/April. If you want to do just fall planting, I’ll turn the dirt again in Sept. and plant in Oct. Hope this helps.
