In the mid-1960s, India was importing millions of tonnes of wheat every year just to keep its population fed. Two back-to-back droughts had pushed the country to the edge of famine, and food aid ships from the United States were practically a lifeline. Against this backdrop, the government launched the High-Yielding Varieties Programme (HYVP) in 1966 – a decision that would change how India grows food forever. Here is how a single agricultural scheme turned a food-deficit nation into one that feeds over a billion people today.

Why India needed the HYVP
By the early 1960s, India’s population was growing faster than its farms could keep up. Most Indian farmers still grew traditional, tall-stalked varieties of wheat and rice. These plants looked lush, but they could not absorb much fertiliser without collapsing under their own weight, so yields stayed low no matter how much care went into the crop.
Then came the droughts of 1965-66 and 1966-67, which devastated harvests across the country and made the food crisis impossible to ignore. Rural India was already dealing with widespread malnutrition, and the gap between how much food was grown and how much was needed kept widening every year. Policymakers realised that simply expanding farmland was not going to solve the problem. India needed crops that could produce dramatically more grain from the same amount of land, and it needed them fast.
This urgency pushed the government to act. The High Yielding Variety Programme was launched in the Kharif season of 1966-67 with the specific goal of attaining self-sufficiency in food grains by 1970-71. It was a bold, time-bound target for a country that had spent nearly two decades struggling to feed itself.
Key crops and techniques behind the HYVP
The HYVP was not just about scattering new seeds and hoping for the best. It rested on a scientific breakthrough that had already worked wonders elsewhere: dwarf and semi-dwarf plant varieties.
Dwarf wheat: the game-changer
The story of dwarf wheat in India is closely tied to agricultural scientist M. S. Swaminathan. He had learned about a short-stalked wheat variety developed in Mexico that carried what breeders call the Norin-10 dwarfing gene, and he invited its creator, American agronomist Norman Borlaug, to work with Indian scientists. Borlaug travelled across India’s wheat belt with Swaminathan after the seeds arrived, and the two set up trials to adapt the Mexican varieties to Indian soil and climate.
Unlike traditional wheat, which could grow over four feet tall and often fell over once it absorbed enough fertiliser, dwarf wheat had short, sturdy stems that could hold up heavier grain heads. This meant farmers could apply far more fertiliser without losing the crop to lodging, which is the technical term for stalks bending or breaking. There was one hurdle scientists had to clear first, though: the original Mexican wheat produced red grains, which were not suited to making chapati, so Indian breeders had to selectively cross and refine the varieties until they got high-yielding wheat with the amber grain colour that Indian households preferred.
The results were dramatic. Within just a couple of years of the programme’s rollout, India’s wheat production jumped from around 12 million tonnes to 17 million tonnes by 1968, a rise of nearly five million tonnes in a single harvest cycle.
New rice varieties
While wheat grabbed most of the early headlines, rice was the other pillar of the HYVP. Since rice is grown across a much wider range of soil types, water conditions, and regional preferences than wheat, breeding a single high-yielding variety that worked everywhere was far harder. Scientists worked on semi-dwarf rice varieties bred for shorter, stronger stems, similar in principle to the wheat breakthrough, along with better resistance to pests and diseases.
The gains in rice were real but more modest and uneven compared to wheat, largely because rice cultivation depends heavily on precise water management, something that varied widely across India’s states. Even so, these new varieties gave farmers in irrigated regions a meaningful jump in output, and they laid the groundwork for further rice breeding work in the following decades.
Challenges and implementation on the ground
Developing a high-yielding seed in a research lab is one thing. Getting millions of farmers, many of whom had farmed the same way for generations, to actually adopt it was an entirely different challenge.
Training farmers and extension staff
The HYVP was designed as a centrally guided but state-implemented programme. Each state government was responsible for selecting suitable districts, building up extension staff, and running training programmes at every level, from district agricultural officers down to village-level workers who interacted directly with farmers. This extension network had to teach farmers not just which seeds to plant, but an entirely new package of practices, including precise fertiliser dosages, irrigation schedules, and pest control methods that traditional farming had never required.
Convincing sceptical farmers was often the hardest part. Many were understandably cautious about abandoning tried-and-tested methods for unfamiliar seeds. Scientists tackled this by setting up demonstration plots on farmers’ own land, letting them see the yield difference with their own eyes before committing their entire field to the new varieties. This on-ground, farmer-to-farmer proof turned out to be far more persuasive than any government pamphlet.
Ensuring supply of inputs
High-yielding varieties are demanding. They need reliable irrigation, timely doses of chemical fertiliser, and protection from pests, none of which were widely accessible to the average Indian farmer in the 1960s. The government had to build an entire input-delivery system almost from scratch. This meant expanding irrigation infrastructure, subsidising fertilisers and pesticides to bring costs within reach of small farmers, and setting up distribution networks so that seeds and chemicals actually reached villages on time for the sowing season. Credit was another bottleneck, since these inputs cost money upfront, so cooperative banks and rural credit institutions were roped in to help farmers finance the switch.
Because irrigation was non-negotiable for these varieties to perform well, the programme’s early success became concentrated in regions that already had strong canal or tube-well irrigation, particularly Punjab, Haryana, and western Uttar Pradesh. Rainfed and drought-prone regions of eastern India were left behind in this first wave, a regional imbalance that policymakers would spend decades trying to correct.
The Green Revolution connection
The HYVP is often remembered as the opening chapter of India’s Green Revolution rather than a separate event. Multi-location trials of semi-dwarf wheat through 1963-65, followed by farmer demonstrations, culminated in what came to be called the Wheat Revolution of 1967-68, a term that captured just how quickly output surged once the new varieties took hold at scale.
What started as a seed-and-fertiliser programme for two staple crops eventually broadened into a much larger transformation of Indian farming. Over the following two decades, high-yielding techniques spread to more crops, more states, and eventually into allied sectors like dairy and fisheries. The government continued building on this foundation, and by the 1970s India had reached the food self-sufficiency it had set out to achieve, moving away from dependence on imported grain.
Decades later, the government has had to actively work on correcting some of the regional gaps that the original HYVP left behind. Programmes such as Bringing Green Revolution to Eastern India were introduced specifically to extend similar productivity gains to states that missed out on the first wave, while also addressing newer concerns like groundwater depletion and soil health that emerged from decades of intensive fertiliser and irrigation use. In many ways, India is still managing the long-term consequences and unfinished business of the choices made back in 1966.
What do you think?
What do you think? Do you think a programme as tightly focused as the HYVP, one that concentrated resources on a handful of crops and regions, was the right call given the food crisis at the time? And looking at India’s ongoing struggles with groundwater depletion and regional farm inequality today, could a more evenly spread approach back in 1966 have avoided some of these long-term costs?
