Under which head nil return for agriculture income filed??

My client has agriculture income of Rs 300000 for FY 13-14 with no other income, out of which he invested in LIC Rs 35000. Having agriculture income, it's exempt from tax. But i need to file a nil return with the same income. Could any one help me under which head should i need to file ITR???

It's little urgent. immediate response will be highly appreciated.

Many Thanks
