Hay is not a block or item in any edition of minecraft. If you are referring to long grass, which naturally grows on grass blocks, then it is not currently in Minecraft: Pocket Edition. You also may be referring to wheat which is aquired by using a hoe on grass and then planting seeds there (prefferably done with water next to or near it), after a while the seed(s) will have grown and become yellow, you ten punch this and you will receive wheat and seeds.
With hay.
