Dear Aditya,
For Agri land no one(as far as I investigated) gives loan, since it is not legally possible for them to take back the land, in case of defaulters. moreover govt and politicians will support farmers only. so it is purely a suicide attempt for load provider. One possible thing for you to buy an agri land is. Go for mortgage loan of your own house, which is of less interest rate(Jewellery loan is even more lesser in interest rate) and buy some virgin land at remote location. One thing to consider is good soil and water availability. Put some dedication on farming and you can repay the mortgage loan within five years.
This is what I did recently..
All the best,
