Bt Cotton and India’s Cotton Productivity Mission: Can Innovation Revive Cotton Growth?

Why is it in News?

The Union Cabinet has approved the Mission for Cotton Productivity with an outlay of ₹5,659 crore for the period 2026–27 to 2030–31. The mission aims to increase India’s cotton lint productivity from the current 441 kg per hectare to 755 kg per hectare by 2031, addressing the stagnation in cotton yields witnessed over the past decade.

The initiative has reignited debates around the future of Bt Cotton, biotechnology-driven agriculture, seed innovation, regulatory approvals, and India’s long-term cotton competitiveness.

For UPSC aspirants, this topic is important under Agriculture, Biotechnology, Genetic Engineering, Agricultural Productivity, and Food Security.

About Bt Cotton

Bt Cotton is the only genetically modified (GM) crop approved for commercial cultivation in India.

It was introduced to protect cotton crops from destructive insect pests and significantly improve agricultural productivity.

The technology derives its name from:

Bacillus thuringiensis (Bt)

a naturally occurring soil bacterium known for producing insecticidal proteins.

What is Bt Cotton?

Bt Cotton is a genetically engineered cotton variety into which specific genes from Bacillus thuringiensis have been inserted.

These genes enable the plant to produce special proteins called:

Cry Proteins

These proteins are toxic to certain insect pests but generally harmless to humans and most non-target organisms.

How Does Bt Cotton Work?

The mechanism is based on biological pest control.

Step 1: Gene Introduction

Genes from Bacillus thuringiensis are inserted into cotton plants.

Step 2: Production of Cry Proteins

The cotton plant continuously produces Cry proteins in its tissues.

Step 3: Pest Consumption

When insect larvae feed on the cotton plant, they ingest these proteins.

Step 4: Gut Damage

In the alkaline gut environment of the insect, the proteins become activated and damage the gut lining.

Step 5: Pest Death

The pest stops feeding and eventually dies.

Target Pest

Bt Cotton was primarily designed to combat:

American Bollworm (Helicoverpa armigera)

one of the most destructive pests affecting cotton cultivation.

Before Bt Cotton, bollworm infestations caused enormous crop losses and forced farmers to rely heavily on chemical pesticides.

Evolution of Bt Cotton in India

Bollgard I (2002)

The first generation Bt Cotton introduced in India.

Contained:

Cry1Ac Gene

which targeted bollworm pests.

Bollgard II (2006)

The second generation variety.

Contained:

Cry1Ac + Cry2Ab Genes

This dual-gene technology aimed to:

• Improve pest resistance.
• Delay the emergence of resistant insect populations.
• Enhance durability of protection.

Regulatory Framework for GM Crops in India

The approval and regulation of genetically modified crops involve multiple institutions.

Genetic Engineering Appraisal Committee (GEAC)

Genetic Engineering Appraisal Committee

Functions under the Ministry of Environment, Forest and Climate Change.

Role

• Environmental approval of GM crops.
• Assessment of biosafety.
• Evaluation of commercial release proposals.

It is the apex regulatory body for GM organisms in India.

Review Committee on Genetic Manipulation (RCGM)

Functions under the:

Department of Biotechnology

Role

• Monitoring research activities.
• Supervising field trials.
• Assessing biosafety during experimentation.

Bt Cotton Revolution in India

The introduction of Bt Cotton transformed India’s cotton economy.

The journey can broadly be divided into two phases.

Phase I: The Boom Period (2002–2014)

Rapid Increase in Production

Cotton production increased dramatically.

2002–03

Approximately:

13.6 Million Bales

2013–14

Reached nearly:

39.8 Million Bales

This represented one of the most significant productivity gains in Indian agriculture.

Yield Growth

Average lint productivity increased from:

278 kg/ha

to

566 kg/ha

within a decade.

Reduction in Pesticide Usage

Bt Cotton significantly reduced dependence on insecticides targeting bollworms.

Benefits included:

• Lower production costs.
• Reduced pesticide exposure.
• Protection of beneficial insects.

Economic Transformation

India transitioned from:

Cotton Importer

to

Major Cotton Producer and Exporter

becoming one of the largest cotton producers globally.

Phase II: Plateau and Decline (Post-2014)

Despite initial success, productivity gains began slowing.

Saturation of Bt Cotton Coverage

By 2014:

More than 95%

of India’s cotton acreage was under Bt Cotton cultivation.

Yield Stagnation

Average productivity gradually declined to:

440–450 kg/ha

which remains close to current levels.

Falling Production

Cotton output dropped from peak levels to approximately:

29 Million Bales

in recent years.

Why Has Cotton Productivity Stagnated?

Several factors contribute to the slowdown.

Pest Resistance

Over time, certain pest populations have developed resistance to Bt toxins.

This reduces the effectiveness of the technology.

Emergence of Secondary Pests

While bollworms were controlled, other pests gained prominence.

Examples include:

• Pink Bollworm
• Whitefly
• Mealybugs

These pests require additional management strategies.

Lack of New Technologies

No major next-generation GM cotton technologies have been commercially approved in India for many years.

This has limited innovation.

Climate Stress

Cotton cultivation faces increasing challenges from:

• Heat waves
• Droughts
• Irregular rainfall
• Extreme weather events

Soil Health Issues

Long-term monocropping and nutrient imbalances have affected productivity.

Mission for Cotton Productivity (2026–31)

The newly approved mission seeks to address these challenges.

Financial Outlay

₹5,659 Crore

Duration

2026–27 to 2030–31

Productivity Target

Increase cotton lint productivity from:

441 kg/ha

to

755 kg/ha

by 2031.

Key Objectives

Improve Seed Technology

Promote high-yielding varieties and advanced genetics.

Enhance Farmer Awareness

Strengthen extension services and scientific farming practices.

Promote Sustainable Cultivation

Encourage efficient use of:

• Water
• Fertilizers
• Pesticides

Strengthen Research

Support biotechnology and cotton breeding programs.

The Policy Debate

A major debate surrounds whether current regulatory policies are restricting innovation.

Intellectual Property Concerns

Private biotechnology firms argue that excessive price controls reduce incentives for research and development.

Supporters believe stronger intellectual property protection could encourage investment in new technologies.

Regulatory Delays

Critics argue that approval processes for new biotechnology products are often lengthy and uncertain.

This may discourage innovation.

Public Research Gap

If private-sector participation remains constrained, public research institutions may need significantly greater funding to fill the innovation gap.

Importance of Cotton for India

Cotton plays a critical role in India’s economy.

Livelihoods

Supports millions of:

• Farmers
• Agricultural laborers
• Textile workers

Textile Industry

Cotton is the backbone of India’s textile sector.

The textile industry contributes significantly to:

• Manufacturing output
• Employment generation
• Exports

Foreign Exchange Earnings

Cotton and textile exports contribute substantially to India’s export basket.

Challenges Ahead

Climate Change

Increasing weather variability threatens productivity.

Pest Evolution

New resistant pest strains continue to emerge.

Research Investment

Continuous innovation is essential.

Regulatory Balance

Policymakers must balance:

• Biosafety
• Farmer welfare
• Technological advancement

Way Forward

To revive cotton productivity sustainably, India should focus on:

Accelerating Scientific Innovation

Encouraging research into next-generation cotton technologies.

Strengthening Biosafety Evaluation

Ensuring transparent and science-based regulatory processes.

Increasing Public R&D Funding

Supporting agricultural universities and biotechnology institutions.

Promoting Integrated Pest Management

Reducing overreliance on a single technology.

Enhancing Climate Resilience

Developing drought-tolerant and climate-resilient cotton varieties.

A balanced approach that combines biotechnology, sound regulation, farmer welfare, and scientific innovation will be essential for achieving the goals of the Cotton Productivity Mission.
