Core Legal Answer & Context: The assessment of land revenue is a primary function performed during settlement operations, which involve surveying, classifying, and valuing land to determine the revenue payable. Under the M.P. Land Revenue Code, 1959, the Settlement Officer is the designated authority responsible for conducting these operations and assessing the land revenue for the entire district. Other officers like the Collector or Commissioner have supervisory or appellate roles, but the initial assessment is by the Settlement Officer.

Relevant Statutes and Sections: M.P. Land Revenue Code, 1959, particularly Chapter X (Assessment and Re-assessment of Land Revenue) and Sections related to the powers and duties of the Settlement Officer.

Important Landmark Cases: Not applicable for a question on the statutory duties of a revenue officer.

Clear Conclusion: Land revenue for a district is assessed by the Settlement Officer.
