Govt made road in my agriculture property

first see by which authority the road had been built over your land. If possible find out by filing application under Right to Information Act. When you get the authority give them a notice under section 80 of Code of Civil Procedure asking for monetary compensation giving them time of 15 days or 1 month to respond. If you do not receive any information or you are not satisfied with the reply file a Suit for compensation before Civil Court.

The construction could have been carried out only after the land has been acquired through the due process of law.  The posting is silent as to whether the due process has been followed. If not, you may approach the High Court through a Writ Petition.

The road can not be laid to a village with your land alone, and  Govt might have acquired land in a legal manner by following up laid down procedures like notification of acquisition, land required, use of such land, and the land owners, and a village meeting, etc.  You can not deal with Govt alone, make a collective and co-ordinated effort by forming a group and engaging a competent lawyer.

Government have acquired the land for public purposes after adopting due process of law and farmer(s) / owners have been duly compensated in terms of Land Acquisition Act, 1894   and/or Section 77 of The Fair Compensation and Transparancy in Land Acquision, Rehabilitation and Resettlement Act, 2013 which author did not share with experts in present post.

Government can acquire yoir land for public purpose, even against your wishes, but you are entitle for Fair Compensation.
