The Field Operations Division of NSSO has the overall responsibility of providing technical guidance to the States in developing suitable survey techniques for obtaining timely and reliable estimates of crop yield, bringing out uniformity in definitions and concepts and providing assistance in training the State field personnel. It also undertakes supervision over the primary field work of the State Governments in respect of area enumeration, area aggregation and Crop Cutting Experiments.

The supervision on field work for qualitative improvement in Agricultural Statistics is carried out through well organised sample survey under Improvement of Crop Statistics (ICS) Scheme. The Scheme aims at locating, through joint efforts of Central and State agencies, the deficiencies in the State system of Crop Statistics and suggesting remedial measures for effecting lasting improvements. The ICS scheme is in operation in 19 Land Record States/UTs and 3 Non-land Record States.

The responsibilities of supervisory staff of the NSSO (FOD) and State Governments inter-alia involve sample check in non-overlapping samples on (i) area enumeration and aggregation in about 10,000 sample villages in each season (ii) about 30,000 Crop Cutting Experiments in a year carried out by State primary workers.

The findings of the sample supervision are brought out in the form of State-wise reports for two major seasons and an All India Status Report titled 'Review of Crop Statistics System in India through Scheme for Improvement of Crop Statistics'.

Work related to planning of survey, compilation & analysis of data and publication of the reports is done at Agricultural Statistics (AS) Wing of NSSO (FOD) located at Faridabad.
