100x130x70x130 is roughly 1/4 acre. That's a good size for a paddock, but even with just grazing during only the day, whatever edible stuff is there will be gone in a couple weeks. It really takes about 2 acres to be able to rotate the grazing and keep the grass alive. It's not just how much they eat, but the constant foot traffic in a small area is very hard on the grass, too. Bottom line...don't bother planting grass, you'll have a dry lot and need to always feed hay anyway (and that's fine).
Other advice...unless you really enjoy the work of cleaning up the trees/pine straw/etc preparing for a horse, save yourself the effort and don't bother. If you just fence the area and put a horse in there, it will 1) eat everything edible 2) trample the rest as it moves around, and the area will be cleaned up for you.
