Improvement of Crop Statistics (ICS)

            The scheme “Improvement of Crop Statistics” has been introduced to find out the deficiencies in collection of primary data under the scheme EARAS through sample checks and to suggest remedial measures. The Scheme has been in operation in the State from 1976-77. The main objective of the Scheme is to locate  through the joint efforts of the central and state authorities ,the deficiency in the system of collection of primary data under the scheme EARAS through sample check by higher supervisory officers /staff of Central (NSSO) and State (SASA) authorities and to suggest remedial measures both on area enumeration & yields estimation.

Scope and Coverage

Sample check on  Area enumeration

            220 villages each for Central & State samples are selected on matching basis for sample check on area enumeration.

Supervision on Crop cutting experiments (CCEs).

            260 , 390 and 180 crop cutting experiments for Autumn , Winter & Summer season respectively are planned for Central and State samples on matching basis for Supervision on crop cutting experiments. The details are given below.

No. of Crop Cutting Experiments(CCEs)

• 1660 crop cutting experiments (830 by central Agency and 830 by state Agency (SASA) ) are to be conducted in the state.

• Following 3 types of schedules are used for ICS, Scheme:-

i)            AS-1.0 (For Area Enumeration).

iii)          AS-1.1 (Transcription & Area Aggregation).

For Transcription and Area Aggregation the villages to be covered as per the  following principles:-

i)                    Autumn- 40%

ii)                   Winter & Summer-30% each.

Methodology

FOD is responsible for all activities including survey design, field operations, data processing and preparation of reports under the ICS scheme.

In Odisha ,it was introduced during 1976-77 covering 6% of the villages which subsequently increased to 10% in 1977-78 and 20% level in 1981-2 onwards. For this purpose , each Community Development Blocks has been considered as a stratum.

Design & Sample selection

            The design adopted for the selection of villages for sample check on area is one of stratified random sample, where a tehsil/taluka/sub-division or a group of them is taken as a stratum in the land records states. For Odisha , a block or a group of blocks constitutes a stratum. The total number of villages allotted to each state is first distributed among the districts and then among the strata in proportion to the gross cropped area ensuring at least two villages for a stratum. The selection of villages for each villages for check on area enumeration and crop cutting experiments is made jointly by SASA and the region NSSO in such a  way that the two sets of supervision villages(one for NSSO and the other for the SASA) are non-over lapping. The scheme for EARAS is function in Odisha ,under the scheme it is envisaged to undertake complete enumeration in a set of 20% of the total number of villages in the state in a year, with a view to complete all the villages in course of 5 year

The villages to be taken up for sample on area enumeration during an agricultural year are selected at Regional office of National Sample Survey Organization out of the crop cutting villages selected under the scheme EARAS. Villages including additional villages for crop cutting experiments, Crops and number. of experiments to be Supervised during each season of an Agricultural year are planned by National Sample Survey Organization. All villages selected for sample check on area enumeration are covered during three seasons for the purpose of check on transcription totalling different crop seasons (40%, 30%& 30%, of the total villages during Autumn, Winter & Summer Seasons respectively).The villages for each crop season are decided by NSSO.

 Sample Check for Field Operation

The Sample check consists of three phases. (i) Sample check on Area Enumeration.(ii) Supervision of Crop Cutting Experiments. (iii) Check on transcription and totalling.

Sample check on Area Enumeration

Stratum –for this purpose a CD blocks will be considered as a stratum depending on the gross cropped area and also the geographical contiguity of the blocks. Grouping of blocks will be made at regional office. NSSO(FOD) located at SASA Hqrs. After the selection of villages is completed as per the procedure adopted by NSSO two lists of the selected villages for each district will be prepared as per Statement 2 and 2A .Statement 2-villages selected for check on Area Enumeration will be prepared separately for central and state sample s for each district. Statement 2A (additional villages ) will be prepared first as a total list without dividing it among the central and state samples) and these additional villages divided into central and state sample separately. All villages selected for sample check are covered during each crop season of an agricultural year. Sample check for crop cutting experiments-

Selection of  sample villages.

The selection of sample villages for supervision of crop cutting experiments will be done in two stages.(a) villages will be selected from the list of villages already selected for sample check on Area Enumeration and in which crop cutting experiments are planned. If the number of villages required for supervision of crop cutting experiments get selected from the villages selected for sample check on area enumeration then no further selection is necessary. If however there is any shortfall in the number of villages required for supervision of crop cutting experiments additional number of villages will have to be selected in the second stage.This will be done from the rest villages selected for crop estimation surveys. For crop cutting experiments the frame will be split in to two sub lists (i) list of villages which are already selected for sample check on crop enumeration and in which crop cutting experiments are planned under CES this is initial frame (ii) Remaining villages are selected as supplementary frame . However, this procedure is completed by NSSO two lists of the selected villages for each district will be prepared as per statement no 2 and 2A (additional). For a selected sample village, 20 plots ( in 4 clusters and each cluster comprising 5 plots) are selected on random basis out of total number of plots of the villages.

After completion of land utilization survey by the Statistical Field Surveyor in a sample village for a season, the Supervisory staff of DPMU for state samples and staff of N.S.S.O for central samples visit 20 selected plots with the help of Maps and R.O.Rs, check plot wise land utilization recorded by  S.F.S and fill- up relevant information in schedule in AS-1.0.
