India’s agricultural universities and ICAR institutes generate hundreds of new seed varieties, pest control methods, and farming techniques every year. But research sitting in a laboratory or on an experimental farm does nothing for a farmer in Bihar or Karnataka unless someone carries it to the field, tests it under real conditions, and proves it works. That job belongs to the first-line extension model, a system built specifically to move technology from scientists to farmers before it ever reaches the regular state extension machinery.

What is the first-line extension model?
Agricultural extension in India runs on two parallel tracks. The first is the field extension system, run by state departments of agriculture and agencies like ATMA, which is responsible for spreading proven technology to the largest possible number of farmers. The second is the frontline or first-line extension system, operated directly by ICAR and State Agricultural Universities, which focuses on adapting and demonstrating new technology and building the capacity of extension staff before it is handed over to the wider extension network.
In other words, first-line extension is where research gets a reality check. Scientists themselves lay out demonstrations on farmers’ fields, watch how a variety or practice performs under actual soil, weather, and resource conditions, and only then feed the results into the mainstream system that state governments use to reach the masses. The core objectives are straightforward: test technology for local suitability, prove its yield and income potential directly to farmers, gather feedback for further research, and train the extension workers who will eventually carry the message forward.
Key projects under first-line extension
Four major ICAR-led projects have defined this model since the 1960s. Each one targeted a different gap in the research-to-field pipeline.
All India Coordinated Project on National Demonstrations (AICPND)
Launched in 1964, National Demonstrations were built on a simple premise: scientists could not expect farmers to adopt new practices on advice alone; they had to show results on the ground. What made these demonstrations different from ordinary field trials was the absence of a separate control plot. Instead, the farmer’s own historical yield and the surrounding fields served as the natural benchmark, and demonstrations of around one hectare were conducted on the land of small and marginal cultivators themselves, with agricultural scientists working alongside local extension staff to run the trials.
Operational Research Project (ORP)
Where National Demonstrations worked plot by plot, the Operational Research Project scaled things up to an entire village or cluster of villages on a watershed basis. The idea was to disseminate a proven technology across a whole community at once while simultaneously studying the practical constraints, like credit access, input availability, or labour shortages, that slowed adoption. This decade also saw ICAR launch the Lab-to-Land and Krishi Vigyan Kendra initiatives alongside ORP, reflecting a broader push to move technology transfer beyond isolated demonstration plots.
Krishi Vigyan Kendra (KVK)
The KVK, or Farm Science Centre, is arguably the most enduring outcome of the first-line extension model. The first KVK was set up in Puducherry in 1974, following recommendations from India’s Education Commission and a committee headed by Dr Mohan Singh Mehta, and it has since grown into a network of 731 district-level centres. A KVK’s mandate covers on-farm testing to check whether a technology suits local farming systems, frontline demonstrations to establish its production potential, and structured training for both farmers and extension personnel. Beyond this, KVKs are expected to act as knowledge and resource centres, supplying farm advisories through ICT and other media so that a farmer without direct access to a scientist can still get reliable, science-based guidance.
Lab-to-Land Programme (LLP)
Launched in 1979 as part of ICAR’s Golden Jubilee celebrations, the Lab-to-Land Programme had a narrower and more socially targeted mandate than its predecessors. Rather than working with farmers broadly, it focused on improving the economic condition of small and marginal farmers, landless agricultural labourers, and in particular Scheduled Caste and Scheduled Tribe households, by putting university and research-institute technology directly into their hands. It was, in many ways, an acknowledgment that technology transfer without attention to equity leaves the most vulnerable farmers behind.
Impact on Indian agriculture
By the early 1990s, ICAR recognised that running four separate frontline projects created duplication and diluted impact. On 1 April 1992, National Demonstrations, the Operational Research Project, and the Lab-to-Land Programme were formally merged into the KVK system, and frontline demonstrations along with on-farm testing became core KVK responsibilities. This consolidation gave India a single, coherent institutional structure for first-line extension instead of a scattering of independent schemes.
The results are visible in outreach data. Farmer engagement with KVKs rose from just 1 percent in 2003-04 to 18.8 percent in 2024-25, a substantial expansion in a country with hundreds of millions of farm households. Cluster Frontline Demonstrations, a direct descendant of the original National Demonstration concept, have played a large role in this, since they are conducted under the close supervision of scientists before being handed over to state departments for large-scale replication. This format, first formalised through the Technology Mission on Oilseed Crops in the mid-1980s, remains the standard method through which newly released crop technologies are proven in farmers’ fields across different agro-climatic zones before wider release. Improved seed varieties, climate-resilient practices, and integrated farming systems have all spread through this scientist-to-farmer pipeline, with the added benefit of generating real production data that state extension staff can use with confidence when advising farmers at scale.
Challenges and future prospects
Despite this progress, first-line extension in India faces real limits. Even with 731 KVKs and a growing engagement rate, the sheer number of farm households in the country means direct scientist contact still reaches only a fraction of cultivators. Agriculture being a state subject in India also means that how extension is organised, funded, and staffed varies considerably from one state to another, which creates uneven quality of service even within the same national framework.
ICAR’s own leadership has flagged specific gaps that need addressing. Subject Matter Specialists at KVKs need stronger capacity in areas that have grown in importance but were not part of the original mandate, including post-harvest management, value addition, climate change adaptation, and women’s participation in farming. In response, ICAR has pushed newer initiatives such as Farmer FIRST, aimed at deepening the farmer-scientist interface for continuous feedback, and ARYA (Attracting and Retaining Youth in Agriculture), designed to bring young people back into farming through technology-driven, economically viable models. There is also a broader recognition within the extension community that the frontline system needs to become more pluralistic and better coordinated with private and voluntary players, rather than relying on a single public-sector channel to reach every farmer.
Digital delivery is likely to be the next major shift. KVKs are already mandated to provide advisories through ICT, and as smartphone penetration rises in rural India, the first-line extension model has an opportunity to combine its scientist-verified, field-tested approach with the reach of digital platforms, closing the gap between research stations and remote farms faster than physical demonstrations alone ever could.
What do you think? Should India’s first-line extension system be expanded further under ICAR and the KVK network, or does the scale of the farming population demand a much larger role for state governments and private players? And as climate change reshapes what “proven technology” even means, how quickly can a system built in the 1960s and 70s adapt to test and validate solutions farmers need today?
