Index of survey / Khasra Number is included in:

This question focuses on where the index of survey or Khasra numbers is maintained within land records. The Register Periodical Record is the correct answer because it is a comprehensive document that is periodically updated to reflect all changes in land ownership, cultivation, and other rights, including an updated index of Khasra numbers for easy reference and identification of land parcels.

• Register Gardawari is for crop inspection.
• Register Intaqalaat (Mutation Register) records changes in ownership but is not the primary index of all survey numbers.
• Inspection Register is for recording findings during inspections, not for maintaining a general index of land parcels.

The Periodical Record serves as a master record for land details, including the Khasra index.
