Smart Seed Coating: ICAR-IIOR’s Biopolymer Seed Technology
Why in the news
A research institute under ICAR unveiled a coating that wraps seeds with protective and nourishing inputs in one go, aimed at helping farmers, especially in rainfed regions, cope with climate stress.
Key facts
- Developer: ICAR-Indian Institute of Oilseeds Research (IIOR), Hyderabad; announced through the Agriculture Ministry on 18 June 2026.
- Status: Indian patent granted; base is a biodegradable biopolymer.
- Replaces single-purpose seed treatments with a multifunctional shield.
- Rainfed farming covers roughly 52% of India’s net sown area, where this technology fits best.
- The institute seeks partners such as State Seed Development Corporations, National Seed Corporation, FPOs, seed processors and private seed companies.
Trial results
| Test | Outcome |
|---|---|
| AICRP-Seed multi-location trials on soybean, maize, groundnut, chickpea, cotton, mustard, pigeon pea | 12% to 37% productivity gain over untreated controls |
| Telangana field demonstrations on groundnut and soybean | Nearly 30% yield improvement over farmer practice |
How it works
- Layered encapsulation: seed coated in biodegradable biopolymers.
- Input integration: the layer carries microbes, NPK, micronutrients, crop-protection agents and growth promoters.
- Microenvironment activation: soil moisture triggers a protective zone at the seed-soil interface.
- Targeted release: nutrients and biologicals reach the root zone, aiding root growth and stress tolerance.
Significance
- Breaks down naturally, so no soil damage or chemical pollution.
- Combines protection, nutrition and biological support in a single application.
- Adaptable to cereals, millets, pulses, oilseeds, fibre crops, fodder, vegetables, spices and horticulture.
- Guards seedlings against erratic monsoon, drought, heat spikes, soil degradation and pests.
Background bodies
- ICAR-IIOR: began in 1977 as National Research Centre for Oilseeds Crops, became a Directorate in 1986 and IIOR in 2014; works on castor, safflower, sesame, niger and sunflower.
- ICAR: founded 16 July 1929 as Imperial Council of Agricultural Research, renamed in 1946; HQ Krishi Bhavan, New Delhi; under DARE.
- AICRP-Seed: multi-location trials in varied agro-climatic zones for location-specific seed recommendations.
- Biopolymers: natural-source polymers such as cellulose, starch, chitin, alginate, pectin, agar; biodegradable and renewable.
Exam angle
- IIOR location: Hyderabad; parent body ICAR.
- ICAR origin: 1929 as Imperial Council.
- Seed coating base: biodegradable biopolymer.
