Digital land records and Bhulekh verification
Modern digital revenue portals help farmers check their officially recorded land holdings.
- Bhulekh Land Extracts: Inspect your RoR, Khatauni, or 7/12 extract online on state land portals (e.g., UP Bhulekh, MP Bhulekh, Jamabandi, AnyRoR).
- Metric Records: Official government records record parcel area in hectares and ares (e.g., 0.4047 ha = 1 acre).
- Subsidy Applications: Subsidies under PMKSY, SMAM, and certified seed schemes are calculated based on registered land area.
- Confirm local rod (gatha) measurements with your village revenue accountant (Patwari or Lekhpal).
