I am no expert on pasture or hay, but shortly after buying our place we seeded the former owner's vegetable patch with a mix of 3/4 alfalfa and 1/4 timothy. We just broadcast the seed over the bare ground in spring and it grew well and comes back each year. The original idea was for it to be used as a green manure to improve the soil, but now that we have rabbits and geese, the "crop" comes in very handy. It's not a large area - about 40' x 25' perhaps - but we can get two cuttings a year for hay (we just use a scythe) and fresh cuttings for the geese and rabbits all season. Good return for very little work and the critters thrive on it. And - bonus! - the wild bunnies leave our new vegetable garden alone.
