Income tax query

I have inherited an agricultural land out of urban area in 1990 and I have sold it at 200000 in f.y.-2017-18
I want to know if this is taxable or not?, if it is under the burdern of tax liability then under which section?
Please provide me your suggestions.
Happy New Year to all the respectable law associates.
