Indian Agriculture Part 9
How seeds, fertilisers, credit, mechanisation, and digital platforms decide the per-hectare yield.
Previous Year UPSC-CSE Questions By the end you will be able to draft model answers for the following UPSC questions. Each question carries a collapsible framework showing how to approach it in the exam.
- UPSC Prelims 2020Consider the following activities:
- Spraying pesticides on a crop field
- Inspecting the craters of active volcanoes
- Collecting breath samples from spouting whales for DNA analysis
At the present level of technology, which of the above activities can be successfully carried out by using drones?
How to approach this Prelims question
Approach: All three activities are documented drone applications. Pesticide spraying is now formalised under the NaMo Drone Didi scheme; volcano-crater inspection and whale-DNA collection are widely cited applications in research literature.
Trap to watch: Pre-eliminating any statement on the assumption that drone applications are confined to terrestrial agriculture misses the all-correct pattern.
Key facts to recall:
- NaMo Drone Didi scheme for agricultural spraying launched 2023
- Drones surveil active-volcano craters where human entry is risky
- Drones collect whale-breath samples for non-invasive DNA analysis
- Drone applications span agriculture, research, defence, and surveillance
Answer signal: Correct answer is (d): 1, 2 and 3 (all three).
- UPSC Prelims 2023Consider the following heavy industries:
- Fertilizer plants
- Oil refineries
- Steel plants
Green hydrogen is expected to play a significant role in decarbonizing how many of the above industries?
How to approach this Prelims question
Approach: All three industries use hydrogen at scale today; green hydrogen substitution decarbonises each. National Green Hydrogen Mission targets these as priority sectors.
Trap to watch: Confining green hydrogen to power generation misses its primary near-term role as a feedstock substitute in heavy industry.
Key facts to recall:
- Fertiliser ammonia synthesis uses hydrogen feedstock
- Oil-refinery hydroprocessing uses hydrogen
- Steel direct-reduced-iron production uses hydrogen
- National Green Hydrogen Mission targets these three
Answer signal: Correct answer is (c): All three.
- UPSC Prelims 2021Bollgard I and Bollgard II technologies are mentioned in the context of
How to approach this Prelims question
Approach: Bollgard is a brand name for Bacillus thuringiensis-modified cotton hybrids developed by Monsanto. Identify the broader category: genetically modified crop plants.
Trap to watch: Distractors c (plant growth substances) and d (biofertilisers) reference different biotechnology applications; option a (clonal propagation) refers to tissue culture which is unrelated to Bt traits.
Key facts to recall:
- Bollgard I uses single cry1Ac Bt gene
- Bollgard II adds cry2Ab gene (two-gene hybrid)
- Targets Helicoverpa armigera cotton bollworm
- Regulatory clearance: Bollgard I in 2002, Bollgard II in 2006
Answer signal: Correct answer is (b): developing genetically modified crop plants.
Inputs and technology are the operational levers that determine the productivity of Indian agriculture, measured as output per hectare per crop cycle. The principal inputs are high-yielding-variety (HYV) seeds tracked through the Seed Replacement Rate (SRR), chemical fertilisers covered under the Department of Fertilisers with a persistently imbalanced NPK ratio, pesticides for crop-protection, farm mechanisation under the Sub-Mission on Agricultural Mechanisation (SMAM), and water (covered in Agriculture Part 8 Irrigation). The technology layer adds agricultural biotechnology (Bt cotton hybrids under the Bollgard I and Bollgard II technologies), precision agriculture, digital marketing platforms like the electronic National Agriculture Market (e-NAM) launched 2016, institutional aggregation via the 10,000 Farmer Producer Organisation (FPO) Scheme launched 2020, and drone-based services under the NaMo Drone Didi scheme launched 2023. The headline productivity gap is the below-global-leader yield in rice, wheat, and oilseeds despite area-leading positions.
Background and Historical Context
India's agricultural productivity gap is the binding constraint on doubling farmers' income, the central rural-policy goal of the past decade. While India leads the world in milk production and is among the top global producers of rice, wheat, cotton, and sugarcane by total output, the per-hectare yield trails leading countries by substantial margins. Closing this gap requires coordinated improvement across the input package (seeds, fertilisers, water, mechanisation) and the technology layer (biotechnology, precision agriculture, digital marketing). UPSC Prelims has tested drone-based agricultural applications (UPSC Prelims 2020), green-hydrogen decarbonisation of fertiliser plants (UPSC Prelims 2023), and Bt cotton hybrid biotechnology (UPSC Prelims 2021).
What is the significance of the inputs-and-technology architecture? Three operational dimensions follow. The input-package coordination binds HYV seed adoption to assured irrigation, balanced fertiliser application, and timely pest control; a single weak input collapses the whole productivity gain. The technology-adoption channel sits across public-sector research (ICAR network) for seeds, private-sector biotechnology (Monsanto-Mahyco Bollgard for Bt cotton) for traits, and platform-economy aggregation (e-NAM, FPOs) for market access. The productivity-constraint geography splits between the high-productivity Indo-Gangetic Plain (Punjab, Haryana, Western Uttar Pradesh) and the low-productivity rainfed peninsular and eastern India belts, with the productivity gap concentrated in rainfed regions covered by NMSA-Rainfed Area Development.
Current policy threads include the IFFCO nano-urea launched 2021 as a 500-millilitre bottle replacing one 45-kilogram urea bag with substantially lower carbon footprint; the NaMo Drone Didi scheme launched 2023 targeting around 15,000 women self-help groups with drone training and equipment for spraying and surveying; the 10,000 FPO Scheme launched 2020 with around 6,865 crore rupees outlay over five years; the e-NAM platform integrating over 1,000 mandis across states for unified online price discovery; and the Sub-Mission on Agricultural Mechanisation Custom Hiring Centres for small-and-marginal farmers who cannot afford individual machinery. The institutional-design lesson is that the input-and-technology layer has shifted from a single-channel (state-controlled HYV seed plus fertiliser) Green Revolution model to a multi-channel (public research plus private biotechnology plus platform aggregation plus equipment-as-a-service) architecture.
Introduction: Inputs, Technology, and the Productivity Gap
Why input coordination determines productivity
Indian agriculture's productivity is determined by the coordinated availability of five input categories: seeds (preferably high-yielding varieties), fertilisers (nitrogen, phosphorus, potassium), water (covered in Agriculture Part 8 on Irrigation), pesticides and crop-protection chemicals, and mechanical implements (tractors, harvesters, drones). A single weak input collapses the productivity gain from the others. The technology layer on top adds biotechnology (genetically modified traits), precision agriculture (variable-rate application), digital marketing (e-NAM platform), and institutional aggregation (Farmer Producer Organisations).
The headline productivity gap is the below-global-leader yield per hectare in rice, wheat, and oilseeds despite India holding area-leading or output-leading positions. For several major crops the Indian per-hectare yield sits below the world average and well below intensive systems such as China for rice or Western Europe for wheat. Closing this yield gap is the operational meaning of the doubling-farmers-income policy goal.
- (i) HYV seeds and SRR: Seed Replacement Rate is the share of total seed planted that is fresh certified seed; target ≥33 per cent for self-pollinated crops (wheat, rice) and ≥50 per cent for cross-pollinated crops (maize, sorghum, pulses); actual SRR varies widely across states.
- (ii) Fertiliser consumption: the Indian NPK consumption ratio is persistently skewed toward nitrogen, running well above the recommended 4:2:1 balance, which drives soil-nutrient imbalance and falling response per kilogram of fertiliser applied.
- (iii) Water: Covered in detail in Agriculture Part 8 on Irrigation; groundwater supplies around 65 per cent of irrigated area; the source mix and PMKSY architecture sit there.
- (iv) Pesticides and crop protection: Around 60,000 metric tonnes annual pesticide consumption; Punjab leads per-hectare application; the Insecticides Act 1968 regulates registration and use.
- (v) Mechanisation: Sub-Mission on Agricultural Mechanisation (SMAM) under Ministry of Agriculture; Custom Hiring Centres for small-and-marginal farmers; mechanisation index varies across regions and crops.
Technology Layer: Biotech, Nano-urea, Drones
Bt cotton biotechnology, IFFCO nano-urea, NaMo Drone Didi
Indian agricultural technology spans three principal channels: biotechnology for trait improvement (the canonical case being Bt cotton under Bollgard I and Bollgard II technologies from Monsanto-Mahyco), nano-fertilisers for input efficiency (IFFCO nano-urea launched 2021 as the lead example), and drone-based services for spraying and surveying (NaMo Drone Didi launched 2023 targeting women self-help groups). Each channel addresses a distinct productivity bottleneck: biotech for pest resistance, nano-fertilisers for nitrogen-use efficiency, drones for labour-saving precision application.
- (a) Bt cotton (Bollgard I, Bollgard II): Genetically modified cotton with Bacillus thuringiensis gene for pest resistance; regulatory clearance 2002 (Bollgard I) and 2006 (Bollgard II with two genes); covers the bulk of Indian cotton acreage; pink-bollworm resistance breakdown is the current operational concern (UPSC Prelims 2021).
- (b) IFFCO nano-urea: Launched 2021; 500-millilitre bottle replaces one 45-kilogram urea bag; substantially lower carbon footprint per unit of nitrogen delivered; produced by Indian Farmers Fertiliser Cooperative.
- (c) NaMo Drone Didi: Launched 2023; targets around 15,000 women self-help groups with drone training and equipment for spraying and surveying services; Ministry of Agriculture and Farmers Welfare.
- (d) Precision agriculture: Variable-rate input application using GPS-guided machinery and satellite imagery; limited adoption in India but growing under Digital Agriculture Mission.
- (e) GM mustard (DMH-11): Genetic Engineering Appraisal Committee (GEAC) regulatory clearance contested at Supreme Court; would be the first GM food crop in India if approved.
Platform Aggregation: e-NAM, FPOs, Custom Hiring Centres
Three institutional vehicles for small-farmer aggregation
Indian agriculture's small-and-marginal farmer dominance (around 86 per cent of operational holdings under 2 hectares) creates a structural disadvantage in input procurement, output marketing, and machinery access. Three institutional vehicles address this through aggregation: the electronic National Agriculture Market (e-NAM) for unified online price discovery, the 10,000 FPO Scheme for collective production and marketing, and Custom Hiring Centres for equipment-as-a-service.
- (a) e-NAM (electronic National Agriculture Market): Launched 2016 under Ministry of Agriculture and Farmers Welfare; integrates over 1,000 mandis across states; unified online price discovery; aims to reduce information asymmetry and middleman margins.
- (b) 10,000 FPO Scheme: Launched 2020 with around 6,865 crore rupees outlay over five years; targets formation and support of 10,000 Farmer Producer Organisations across the country; Small Farmers’ Agribusiness Consortium (SFAC), NABARD, and NAFED as implementing agencies.
- (c) Sub-Mission on Agricultural Mechanisation (SMAM): Custom Hiring Centres for tractors, harvesters, drones, and other machinery on rental basis; addresses small-farmer affordability gap; Ministry of Agriculture.
- (d) Krishi Vigyan Kendras (KVKs): District-level technology-transfer centres under ICAR; over 700 KVKs nationally; bridge between research stations and farmers.
- (e) Digital Agriculture Mission: Umbrella for digital public infrastructure in agriculture; includes the Agri-Stack (farmer registry, crop sown registry), India Digital Ecosystem of Agriculture (IDEA), and AgriStack data exchange.
Productivity Constraints and Contemporary Policy
Yield gap, regional variation, policy anchors
Indian agricultural productivity exhibits a sharp regional gradient. The Indo-Gangetic Plain (Punjab, Haryana, Western Uttar Pradesh) achieves wheat-rice yields among the higher Indian ranges, supported by canal-and-tube-well irrigation, balanced HYV adoption, and reliable input supply. The rainfed peninsular plateau and eastern India belts trail substantially, with rainfed dryland constraints limiting productivity. The Department of Agriculture's productivity targets and the National Mission for Sustainable Agriculture (NMSA) Rainfed Area Development component focus on closing this gap.
- (a) Indian yield versus global leaders: rice yields trail China and the global average; wheat yields trail intensive Western European systems; oilseeds also trail global leaders substantially. The per-hectare gap, not total output, is the productivity challenge.
- (b) Regional yield gradient: Indo-Gangetic Plain achieves higher per-hectare yields; rainfed peninsular and eastern India trail; rainfed-area constraints dominant in the productivity-gap geography.
- (c) Productivity constraints: Imbalanced NPK ratio, low SRR in rainfed regions, water-stress in dryland, fragmented landholdings, weak extension services, climate variability.
- (d) NMSA Rainfed Area Development component: Focuses on dryland cropping systems, soil-water conservation, and crop diversification; under the National Mission for Sustainable Agriculture umbrella.
- (e) Soil Health Card scheme: Soil-test-based crop-and-nutrient recommendations to farmers; addresses NPK imbalance and over-use of urea.
| Input lever | Policy or scheme | Launch year | Productivity role |
|---|---|---|---|
| Quality seed | National Seeds Policy and Seed Replacement Rate targets | 2002 | Raises genetic yield potential per hectare |
| Balanced fertiliser use | Soil Health Card scheme | 2015 | Corrects nitrogen-skewed application through soil-test dosing |
| Farm credit | Kisan Credit Card under priority-sector lending | 1998 | Funds timely purchase of seeds, fertiliser, and inputs |
| Mechanisation | Sub-Mission on Agricultural Mechanisation and Custom Hiring Centres | 2014 | Cuts labour cost and timeliness loss for small farmers |
| Market access | Electronic National Agriculture Market | 2016 | Improves price realisation and reduces middleman margins |
The institutional-design lesson is that the input-and-technology architecture has shifted from a single-channel Green Revolution model to a multi-channel architecture. The Green Revolution relied on state-controlled HYV seed multiplication, public-sector fertiliser supply, and canal irrigation. The current model adds private-sector biotechnology, platform-economy aggregation, equipment-as-a-service, and digital agriculture. The remaining policy frontier is closing the productivity gap in rainfed and small-and-marginal-farmer segments where the multi-channel model has not yet penetrated at scale.

- 2 and 3 only
- 1 and 3 only
- 1, 2 and 3
Show answer and explanation
Answer: 1 and 2 only
Explanation.
Correct: a (1 and 2 only). Statement 1 is correct: Soil Health Card was launched 2015. Statement 2 is correct: it targets NPK imbalance via site-specific dosing recommendations. Statement 3 is wrong: SHC provides the diagnostic but extension advisory (KVK, state agriculture departments) remains essential for translating the soil-test recommendations into operational practice.
Q2. Consider the following statements about nano urea in India:
- Nano urea is a liquid nitrogen fertiliser launched commercially by IFFCO in 2021.
- Nano urea uses nano-scale particles for higher nitrogen-use efficiency compared to conventional granular urea.
Which of the statements given above is/are correct?
- 1 only
- 2 only
- Both 1 and 2
- Neither 1 nor 2
Show answer and explanation
Answer: Both 1 and 2
Explanation.
Correct: c (Both 1 and 2). Statement 1 is correct: nano urea was launched commercially by IFFCO in 2021. Statement 2 is correct: nano urea uses nano-scale nitrogen particles for higher per-unit nitrogen-use efficiency than conventional granular urea (claimed up to 2x), reducing required volumes and the urea subsidy burden.
Q3. Consider the following statements about fertiliser application in Indian agriculture:
- The recommended NPK ratio for balanced fertilisation is 4:2:1 (nitrogen:phosphorus:potassium).
- Actual fertiliser application in Indian agriculture runs well above the recommended ratio, distorted toward nitrogen.
- The urea-bias in fertiliser application traces to the statutorily-controlled MRP making urea the cheapest fertiliser.
Which of the statements given above are correct?
- 1 and 2 only
- 2 and 3 only
- 1 and 3 only
- 1, 2 and 3
Show answer and explanation
Answer: 1, 2 and 3
Explanation.
Correct: d (1, 2 and 3). All three statements are correct. The recommended NPK balance is 4:2:1; actual application runs well above it and is distorted toward nitrogen; the urea subsidy with a statutorily-controlled MRP keeps urea cheapest and drives the application bias.
Q4. Consider the following statements about the fertiliser subsidy architecture in India:
- Urea has a statutorily-controlled maximum retail price.
- Phosphatic and potassic fertilisers operate under the Nutrient-Based Subsidy (NBS) regime.
- All fertiliser pricing in India is fully market-determined with no government intervention.
Which of the statements given above are correct?
- 1 and 2 only
- 2 and 3 only
- 1 and 3 only
- 1, 2 and 3
Show answer and explanation
Answer: 1 and 2 only
Explanation.
Correct: a (1 and 2 only). Statement 1 is correct: urea MRP is statutorily controlled. Statement 2 is correct: phosphatic and potassic fertilisers operate under the NBS regime which fixes per-tonne subsidy and lets industry set MRP within that constraint. Statement 3 is wrong: Indian fertiliser pricing is HEAVILY ADMINISTERED through the subsidy architecture, NOT fully market-determined.
Q5. Consider the following statements about agricultural extension in India:
- Krishi Vigyan Kendra (KVK) is the district-level frontline extension unit coordinated by ICAR.
- The first KVK was established in 1974 at Puducherry.

- 1 only
- 2 only
- Both 1 and 2
- Neither 1 nor 2
Show answer and explanation
Answer: Both 1 and 2
Explanation.
Correct: c (Both 1 and 2). Statement 1 is correct: KVK is the district-level extension unit coordinated by ICAR through state agricultural universities and ICAR institutes. Statement 2 is correct: the first KVK was established 1974 at Puducherry on the Mohan Singh Mehta Committee recommendation.
Q6. Consider the following statements about seed system in India:
- Seed Replacement Rate (SRR) is the percentage of cultivated area sown with certified seed of recent vintage rather than farmer-saved seed.
- Enhancing SRR is critical for productivity-sustainability bridge under GR 2.0 architecture.
- There is no National Seeds Policy in India because seed regulation is exclusively a state subject.
Which of the statements given above are correct?
- 1 and 2 only
- 2 and 3 only
- 1 and 3 only
- 1, 2 and 3
Show answer and explanation
Answer: 1 and 2 only
Explanation.
Correct: a (1 and 2 only). Statement 1 is correct: SRR is the percentage of cultivated area sown with certified seed of recent vintage. Statement 2 is correct: SRR enhancement is critical for productivity-sustainability bridge. Statement 3 is wrong: National Seeds Policy 2002 exists; seed regulation operates under central architecture (NSC, SFCI, state seed corporations) under the Seeds Act 1966 and the Seeds Bill framework.
