Nuclear Agricultural Technologies
Why in News?
In March 2026, the Indian government highlighted multiple measures to promote these technologies, including mutation breeding and collaborations with agricultural universities to enhance farmer incomes.
About
- High-Level Collaboration: In February 2026, FAO representatives visited the Joint FAO/IAEA Centre to accelerate the transfer of nuclear innovations from laboratories directly to farmers' fields.
- Indian Strategic Push: The Department of Atomic Energy (DAE) recently announced it is actively disseminating Trombay crop varieties (developed via gamma irradiation) to state universities for multi-location trials.
- Sustainable Partnerships: A new partnership with the OCP Group was launched in February 2026 to use nuclear technology for optimizing fertilizer use efficiency and soil health.
Plant Breeding and Genetics
- Mutation Induction: Seeds are exposed to ionizing radiation (gamma rays or X-rays) to induce genetic changes that do not occur naturally at high speeds.
- Climate-Resilient Crops: This technique develops varieties with higher yields, better resistance to pests, and tolerance to drought or flooding.
- Example: Sudan developed a groundnut variety that requires 30% less rain and produces a 27% higher yield.
Insect Pest Management
- Sterile Insect Technique (SIT): Male insects are mass-reared and sterilized using radiation before being released into the wild.
- Environmental Benefit: SIT reduces or eradicates pest populations without the need for harmful chemical insecticides, protecting human health and biodiversity.
- Example: Ecuador successfully used SIT to eradicate the Mediterranean fruit fly, safeguarding millions in fruit exports.
Soil and Water Management
- Isotopic Tracers: Scientists use stable isotopes like Nitrogen-15 to track exactly how much fertilizer a plant absorbs, allowing farmers to reduce waste and pollution.
- Erosion Assessment: Radioactive nuclides from past events are used as "clocks" to measure the rate of soil erosion and determine the effectiveness of conservation methods.
Food Safety and Preservation
- Food Irradiation: Exposing food to controlled ionizing radiation kills bacteria (like Salmonella and E. coli) and parasites without making the food radioactive.
- Extended Shelf Life: This process slows ripening and prevents sprouting in vegetables like potatoes and onions, significantly reducing post-harvest losses.
Animal Health and Production
- Disease Diagnosis: Nuclear-derived molecular techniques (such as PCR tests) allow for the rapid and accurate detection of transboundary animal diseases.
- Nutritional Optimization: Isotopes are used to study animal metabolism, helping to develop better feed that increases milk and meat production while reducing greenhouse gas emissions.
