Only if land falls under urban area, long term capital gain will apply here and a 20% income tax is payable on capital gains with indexation calculations.
Your land will not be counted as capital asset if Land is outside the jurisdiction of a municipality area or not even within eight kilometers of municipality area. In the above case, there won't be any income tax liability on sale of land.

Lock period for new purchase would be three years. If new land is sold before three years, capital gain benefit would be void and you would have to pay 20% income tax on long term gains.
