Extension, Communication and Training

The Extension, Communication and Training Division has a modest programme of dissemination of modern rice production technology since its inception. This includes advisory services, demonstration of proven technology in farmers’ fields, compilation and editing of various reports including Annual Reports, CRRI Newsletters, various technology bulletins and organizing short and long-term training programmes for Subject Matter Specialists and Agricultural Extension Workers of State Governments. Apart from these, Agricultural Extension Officers, Students, Village Agricultural Workers and Farmers, who visit the institute, are regularly appraised of new production technology of rice cultivation through Training and Visit (T&V) Programme. The division also has the responsibility of taking part in agricultural exhibitions conducted by Central and State Governments and supporting art, photography and reprography needs of the scientists.


Growing of improved varieties, use of green manures, chemical fertilizers and improved implements like mould board plough, wetland puddler, Japanese weeders etc. and adoption of improved cultural practices were demonstrated and popularized in adopted villages. This has resulted in an increase in average grain yield from 558 kg/ha to 1080 kg/ha in an intensive cultivation block of 2000 hectares in Cuttack district of Orissa.

Although canal water was available round the year in areas adjoining the Institute, The farmers were not growing a second crop of rice during January-April, because of heavy insect incidence and the land was cropped with pulses or kept fallow during this period. With the perfection of plant protection techniques at the Institute for the dry season, efforts were made for growing summer rice in the canal irrigated area in Cuttack district with varieties like Ptb 10, Mtu 15 and GEB 24. The response by the farmers was remarkable. As against very little or no increase of second crop till 1954-55, thousands of acres began to be cropped with second crop of rice since 1955-56 onwards.

With the introduction of high yielding varieties, the Government of India launched upon the programme of National Demonstrations in 1965. The Institute conducted about 29 mono-crop demonstrations where the rice yields in the range of 5-8 t/ha exceeded the fixed targets, in all cases.

From 1967, multi-crop demonstrations were conducted with a view to achieve higher production per unit area per unit time than obtaining very high yields from a particular crop. Under this programme, 36 demonstrations were completed. These results indicate that adoption of good management practices give an extra yield of 560-1110 kg/ha under good management over farmers’ management in case of high yielding cultivars viz. Supriya and Ratna, respectively.


The division has so far brought thirty technical bulletins and folders encompassing major problems in rice cultivation and their management. In addition to this, the division has been engaged in publishing Annual Reports and CRRI Newsletters (quarterly) in time. The division has also compiled and edited various reports for sending to Council and other agencies from time to time.


Training which aims at improving professional competence of in-service personnel is taken up by this division on a priority basis.

First and second International Training Course on Rice Breeding in collaboration with FAO was organized in 1952 and 1955, respectively. Participants from 12 countries took part in these programmes. National Training Programmes on all aspects of rice cultivation were conducted from 1961 and of late short-term training programmes on rice production technology, Water Management in rice-based cropping systems and use of biofertilizer in rice cultivation were the subjects of training offered by the institute.

This division has conducted twenty long-term training programmes which were attended by trainees from Bangladesh, Vietnam, Korea, Tanzania and Sri Lanka and sixteen short-term training programmes which were attended by Researchers, Agricultural Extension Officers and Subject Matter Specialists. Apart from these, around 27,000 persons (farm peasants, village Agricultural workers and Students) have visited this Institute under Training and Visit Programmes of different State Governments. These visitors were appraised of new rice production technology through audio visual aids, group discussion and visit to experimental fields.

In addition, this division has been providing logistic help for various workshops, conferences, summer institutes and seminars held in this Institute. This division also takes an active part in agricultural and agro-based industrial exhibitions organized by Central and State Governments.
