Yes you can buy agricultural land in chattisgarh. But avoid areas where there are tribal lands which are non transferable to non tribals 

30 acres is maximum ceiling of dry land in chattisgarh. You need to adhere to section 7 of the land ceiling Act in the same

A Pvt. Ltd. company CAN CERTAINLY BUY AGRICULTURAL LAND and develop and perform agricultural activities on it, BUT SUBJECT TO the approved provisions of articles and the Memorandum of the pvt.ltd and MUST be approved by the Registrar of Companies (ROC). There is no requirement of any director being an agriculturist. The Articles of the Pvt. Ltd. co. should clearly outline the agricultural activities the Pvt. Ltd. proposes to indulge in.

Agriculture is a State Subject .There is no Central Law.Each state govt has fixed its own holding limit.  contact local lawyer from chhattisgarh. 

you need prior approval of state govt to purchase agricultural land in name of company of 100 acres 

where the
holder is a member
of a family of more
than five members.
(1) land capable of
yielding two crops
and receiving
assured irrigation

you cannot purchase additional 100 acres of land as you are already holding 30 acres of land 

1.  It is possible to buy 100's of acres of land, PROVIDED proper procedure and permission is taken from the district collector and the industries commissioner.

Dear Sir,

There is no problem what so every if you want to buy a land in central region (Chhattisgarh planes) ie. In districts like Raipur Bilaspur DURG Korba raigarh janhgir Champa and other places where the tribal population is very less.

If I'm not wrong, one is not allowed to buy land where the majority is of tribal groups and it is common in other states too.

 Under the Companies Act,  a regd. co. may perform those activities that are listed in the Objects ,Articles and the memorandum.  By virtue of its objects and articles, as regd. under the companies act,  the P.Ltd., (now non-person)  can function and perform agricultural activities and need not be a agriculturist as in the case of an individual person.

In the future event, if the pvt.ltd. co. folds-up or say closes down,  then it cannot dispose of its agriculture land bank to non-farmers for non-agricultural purposes.  The agricultural activities are limited to the existence of the Co. If there is no company, all the property etc... can be attached by statutory authorities (I.Tax, S.Tax, Revenue Dept., Environment Dept, Pollution Dept among others)  

The ceiling for purchase of agricultural land depends on which state you would like to purchase.

You may clarify the ceiling limit allowed in Chattisgarh state to the private companies for purchase of agricultural land, you can get this clarification from the land revenue department.

Owning land in individual capacity is different to that of the purchase of th same by your company, do not mix up both together.

The law of MP and Rajasthan  applies to this state.

There are no restrictions in these states. Earlier, under Section 17 of the Imposition of Ceiling on Agricultural Holdings Act, 1973, there were certain ceiling limits on buying agricultural land from the ‘Khatedars’ in Rajasthan. The provisions of this section were amended in 2010 and people from other states can now purchase agricultural land here.

Agriculture income is presently Tax-Free in the hands of Individuals.  

Agriculture income in NOT TAX FREE for companies
