The Integrated Agromet Advisory Services (IAAS) located in the Division of Agricultural Physics, Indian Agricultural Research Institute, New Delhi was started in the year 1994 and since then, has been serving the farming community in and around Delhi region. The service covers Najafgarh, Kanjhawala and Alipur block. This is a new scheme prepared by combining the value addition of the two schemes, one operated by IMD and the other by NCMRWF, having the similar basic objectives. Prior to this, Agro-met Advisory Services (AAS) in the country was provided by two organizations namely; India Meteorological Department (IMD) and National Centre for Medium Range Weather Forecasting (NCMRWF). The funding agency is through IMD which till recently was under the umbrella of the Department of Science and Technology, now is under the new umbrella of Ministry of Earth Sciences.


Though agromet advisory services were being regularly provided by above mentioned organizations for the past many years, the demand of the farming community could not be fully met due to certain drawbacks in the system, such as no-availability of skillful weather forecast in all temporal ranges specific to the site of interest to a farmer. Besides this, non-availability of real-time crop data, lack of decision support system for interpretation of weather forecast into advisories and lack of strong outreach/extension mechanism, are some of the other major weakness in the system. With the adoption of multimodel ensemble based district level forecast, the accuracy of forecasts have improved a lot.


Advising timely and need based crop management practices being the major objective of this programme, weather information along with crop wise weather based agroadvisories are passed on to the progressive farmers of the Delhi villages on real time basis through print, electronic media and also through telephone.

The Agrometeorology wing in the Division of Agricultural Physics of the Indian Agricultural Research Institute has been maintaining the class A meteorological observatory with two automatic weather station (One installed by IMD and other owned by the division itself) as well as conventional meteorological instruments.

Usually the experts of the agroadvisory services meet on Tuesdays and Fridays but, occasionally if there is any urgency, the expert asdvisories are ascertained through telephone. Based on the experts advises, the final agromet advisory bulletin is prepared. The biweekly Agromet Advisories bulletins are faxed to Newspapers (Danik Jagaran), uploaded on the unit web page and send through e-mail to the KVK on the same day evening. In addition to this, the Agromet advisories are communicated to some selected farmers through personal contact via Telephone on real time basis and also through email. Also, this bulletin is uploaded in IARI homepage.


The farmers feel it to be useful since they receive advices on appropriate field operations and management practices depending on suitability of weather conditions particularly for newly released high yielding varieties of various crops which they can otherwise access.




The major Objectives of the Integrated AAS scheme are

  • To provide location specific weather forecast and Agro-Meteorological Advisory Service (AAS) as per different climatic conditions and cropping patterns.
  • To implement an efficient outreach system so that the farmers receive weather based agro-advisories specific to their areas and crops on real time basis.
  • To set up operational arrangements for AAS involving extension and information disseminating agencies.



i) Data Recording


The meteorological observatory of IARI is a A-class observatory with conventional meteorological instruments. The past weekly data are communicated to NCMRWF, New Delhi and also the monthly/yearly data to IMD and CRIDA. During previous year two AWSs were installed in the observatory, one by the division and other by IMD.


ii) Data Analysis


The data bank developed by the unit consists of daily meteorological data of the last 59 years and being updated daily. Also the data bank includes products like weekly and monthly values besides the normal values.


iii) Making the product: Agromet advisory bulletin

  • Summary of previous week's weather.
  • Medium range weather forecast information (for the next 5 days)
  • Crop management advisory consisting of standard agronomic management practices under normal weather conditions.
  • Suitably modified agronomic management advisory under forecast of transient weather conditions.
