  2. India Meteorological Department
  3. Public Works Department.
  4. Forest Department.
  5. Southern Railway.
  6. Tamil Nadu Tea Plantation Corporation.
  7. Agriculture Department.
  8. Others.

The daily rainfall data in respect of 622 rain gauge stations in Tamil Nadu are entered in the Computer and stored (By receiving the e-mail from Districts).

Crop Forecast Report

The objective of the Crop Forecast Scheme is to secure and disseminate advance information regarding season-wise area and production of important crops before final figures of area under crops as settled at Jamabandhi and final results of yield rates as per crop cutting experiments become available.

The advance / final estimates reports are sent to Economic & Statistical Adviser to the Government of India, New Delhi and to the Government of Tamil Nadu.

Season and Crop Report

The objective of the scheme is to present detailed district-wise facts and figures pertaining to agriculture. The report contains data regarding classification of Land use, different sources of irrigation, Sourcewise area irrigated, cropwise area irrigated and unirrigated, Production and productivity of important crops etc.

In addition to that the report also contains Rainfall Statistics, average rates of daily wages paid to certain categories of Agricultural labourers, Index number of agricultural wages, Wholesale and Retail Prices of important commodities in selected centres in Tamil Nadu.

Crop Estimation Survey on Food and Non-Food Crops

Crop Estimation Survey on Paddy, Millets, Groundnut, Gingelly, Sugarcane, Cotton and Pulses are being conducted in Tamil Nadu with a view to estimate the average yield per hectare and total production of each crop for the State as a whole and for the individual districts covered by the survey. The surveys are carried out under the overall technical guidance of the Director General, National Sample Survey Organisation (FOD), Government of India, New Delhi.

The names of villages selected for the conduct of experiments on each crop are intimated before the commencement of each Fasli year by the Special Commissioner and Director of Economics and Statistics to the Commissioner of Agriculture who will fix the responsibility of conduct of experiment on the primary workers through the District Joint Director of Agriculture concerned.

The field work relating to the crop cutting experiments is attended by the Agricultural Officers with the assistance of the Village Administrative Officers of the village concerned. The field staff are given training in the conduct of crop cutting experiments by the officers of the Department of Economics and Statistics and National Sample Survey Organisation at the commencement of each Fasli year.

The utilization of the results of the survey are as follows:

  1. Sectoral : The district level average yield and estimated production of paddy, millets, pulses, groundnut, gingelly, sugarcane and cotton at district level serve as guideline for planning at district level.
  2. Regional : The average yield and estimated production of the crops for the State (as a whole) facilitate planning at State level. These details are also used for estimating the contribution of agricultural sector to the State Income.
  3. National : The production estimates of the crops for the State are being used by the Government of India for estimating the All India production and also for preparing Regional Development Plan at National Level.

National Agricultural Insurance Scheme

Comprehensive Crop Insurance Scheme sponsored by the Government of India was implemented jointly by the Government of India and the State Government from the year 1985-86 till 1999-2000 Kharif Season.

The National Agricultural Insurance Scheme (NAIS) was launched from 1999-2000 Rabi Season onwards at All India basis.

In Tamil Nadu, National Agricultural Insurance Scheme is being implemented from 2000-01 Rabi Season onwards.

The objectives of the Scheme

  1. To provide financial support to farmers in the event of crop failure due to drought, flood, etc.,
  2. To restore credit eligibility of farmers after a crop failure for the next crop season.
  3. To support and stimulate production of food-crops, pulses, oil seed crops.

Implementing Agency: For the implementation of National Agricultural Insurance Scheme in Tamil Nadu, General Insurance Company has been named as Agricultural Insurance Company of India Limited with effect from 01.04.2003 as per the announcement made in the Union Budget 2002-03 vide G.O. Ms. No.240, dated 08.08.2002.

In Tamil Nadu, to monitor the Scheme, the State Government has constituted the following two committees viz.,

  1. The State Level Technical Sub Committee on Crop Insurance Scheme under the Chairmanship of Commissioner of Agriculture (SLTSC).
  2. The State Level Co-ordination Committee on Crop Insurance Scheme (SLCCCI) under the Chairmanship of Agricultural Production Commissioner and Secretary to Government, Agriculture Department.

The Commissioner of Agriculture is authorised to notify the selected Blocks / Firkas and crops.

Coconut and Arecanut Survey

Sample Survey for estimation of Area and Yield of Coconut and Arecanut in Tamil Nadu is being conducted since 1959-60.

The objectives of the Survey are -

  1. To estimate the total number of palms of Coconut and Arecanut for the State.
  2. To estimate the average number of bearing and non-bearing palms of Coconut / Arecanut per hectare for the Districts and State.
  3. To estimate the average yield per palm of Coconut and Arecanut and total production per year for the Districts and State
  4. To collect information regarding the agricultural practices like manuring, irrigation, disposal of produce, etc., of the crops.

382 villages are covered under this survey for the year 2007-08

Crop Estimation Survey on Minor Crops

The main objective of the survey is to obtain estimates of average yield per hectare and production of certain Minor Crops at district level and also at State Level with a reasonable degree of precision. In addition to this certain ancillary information like irrigation, manuring, high yielding varieties and other cultural practices adopted in respect of eight corps, viz., Chillies, Onion, Turmeric, Tapioca, Potato, Ginger, Coriander and Cashewnut are collected.

For the year 2007-08, 590 villages were planned. Form-1 have been received in full for all the crops and Form-II have been received for 480 villages.

The crops covered under this survey are not covered in Crop Estimation Survey. These estimates are used in the State Income for the preparation of State Domestic Products.

Crop Estimation Survey on Fruits & Vegetables

The main objectives of the Survey are -

  1. To arrive at reliable estimation of average yield per hectare and Production, estimates of each crop at District and State Level and
  2. Collection of ancillary information on Agricultural practices.

During 2007-08, 550 villages were planned to conduct the survey in eight fruit crops viz., Mango, Banana, Guava, Lemon, Jack, Orange Grapes, Pineapple and five Vegetables viz., Brinjal, Lady’s Finger, Cabbage, Tomato and Sweet Potato.

The above crops are not covered under Crop Estimation Survey. These estimates are used in State Income for the preparation of State Domestic Product.

Irrigation Statistics

To bring out profile on Irrigation Statistics for all the Districts of the State.

Timely Reporting Scheme:

Timely Reporting Scheme for estimating the area under principal crops was first implemented in Tamil Nadu during the year 1972-73 as a centrally sponsored scheme and the entire cost of the scheme was met by Government of India till the year 1978-79.

Thereafter, the expenditure is being shared equally by Central and State Government on 50 : 50 basis. The scheme is found to be very useful to frame agricultural policies and development programmes at State and National level.

The objectives of the Scheme is to frame reliable and accurate estimates of area under 9 principal crops viz., Paddy, Jowar, Bajra, Ragi, Cotton, Groundnut, Sugarcane, Potato and Onion for each season viz. Kharif, Rabi and Summer to frame break up estimates of area separately for irrigated, un-irrigated and varietywise i.e., high yielding and local varieties and to build up Land Use Statistics.

During the year 2007-08, 3458 villages were selected and estimates of area for Kharif, Rabi and Summer seasons have been prepared and sent to Deputy Statistical Advisor, Government of India, New Delhi within the cut off date.

Improvement of Crop Statistics:

The objective of the Scheme is to locate the deficiencies in the system of collection of Agricultural Statistics in the State by the exercising meaningful supervision by Central and State authorities over the primary field workers viz., Village Administrative Officers and suggest remedial measures for the improvement of the system. The scheme is further expected to provide the basis for determining the precise lines n which the improvement in the Crop Estimation System would require to be effected.

Coverage :

The programme of work under the scheme for Improvement Crop Statistics scheme consists of carrying out checks in each agricultural season of the State on -

  1. Enumeration of area recorded by the village officials in a set of selected sample villages.
  2. Preparation of crop abstract statements on the basis of entries made by the Patwari in the Villages.
  3. Supervision of crop cutting experiments conducted by the Primary Workers in the selected State sample villages and
  4. Sample check on aggregation of area above village level.

Marketable Surplus Survey

The objective of the Scheme is

  1. To estimate the surplus or deficit of supply over demand for the seasons and the year.
  2. To determine precisely the quantum of Paddy that the farmers can sell / dispose off in the market for exchange and/ or exchange of goods/ services received by them for the purposes other than agriculture i.e., supply of Paddy to the market.
  3. To assess the farmer’s propensity for sale, quantity retained for farmer’s own use, domestic consumption, quantity disposed for agricultural operation, etc.

Coverage :

Except Chennai and The Nilgiris, all other district are covered. As Chennai is a non-agricultural district and the area under paddy is negligible in The Nilgiris district, these two districts are not covered under the survey. The survey covered the three seasons under Paddy in a year and are defined with reference to the sowing period. The three seasons are Kar, Samba and Navarai.
