Disclosure in itr v for transfer of rural agriculture land

Hello Members,

Recenlty in June 2016 there has been a transfer of Rural Agricultural Land by a Farmer for his land, and cash is deposited for Rs50 Lakhs in Bank Account which is not having any PAN.

Now How can i Disclosue the Transfer or Rural Agricluture Land as Tax Exempt in ITR V in the Farmers Account who doesnot even a PAN. (Ok, PAN may be applied and return can be filed)

Even if Trf. of Rural Agriculture Land is exempt , He would surely get an intimation from Asessig Officer, Saying we have observed Cash Deposit of more than 50Lakhs in to your account may be in next year. How to Substantiate then ?

Please help !
