Can i have tax saving from agricutural expenses?

I am working as assistant professor in a college. I spend a major share of my income for agricultural purposes in my farm which includes purchase of seeds/equipments, salary for farming assistant, electricity etc. Can I avail income tax relaxation for this amount that I spend for agriculture? Although agricultural income is insignificant for me, I consider this as a social service in a way that a farmer's family is having a steady income even if the odds for a bad agricultural output is at large. I purchased the land using my salary arrears and loans. I don't have any other income and I find it a bit difficult as my land is not an ancestral property. I love agriculture and I don't want to stop farming. Please help.
