Buying of Agricultural Land

Sir I am from Uttarakhand and want to purchase agricultural land in Bhuj but as it is clear from various posts that legally I am not entitled to buy Agri land in Gujarat. One of my friend is farmer in Bhuj, we are planning to purchase some land in partnership Please clarify : (1) Is there any legal means of doing this. (2) Can he give me Power of Attorney because land can only be purchased on his name. (3) What if I want to transfer/sale my part of land. (4)Can he sale the whole land without my permission. (5) Please suggest the best legal way to it. (6) What if I purchase non agri land and do farming on it.
