Think twice about bermuda, in Central or West Texas unless you can irrigate it. Lots of people are planting Klien, Wilman Love or W.W. B Dahl around here because their Coastal and Tifton died last year in the drought. We used to plant haygrazer until it got outrageously costly to produce. Then we planted everything in Klien and Willman Love grass, has been the best thing that we have done. It doesn't take near the fertilizer or water that Bermuda does. Bahaia is good for grazing and hay, gets stems like baling wire when it heads out though.
I just planted about 10 more acres of Wilman Love, would have mixed klien with it but all the seed dealers were out of klien. Plant about 2 to 3 pounds per acre, it will cost 12$ per pound which is 24 to 36$ per acre for seed, seems high but once you get it established you will never have to do any thing to it exept spray the weeds and fertilize it.
Disk your ground up really well then broadcast the seed out (it is tiny, smaller than #8 bird shot) drag it or roller pack it, don't get it too deep, no more than1/4 inch or it won't come up.
Cattle love it and it will make 2-3 bales per acre.
