In a major breakthrough for climate-resilient agriculture, the Indian Council of Agricultural Research’s Indian Institute of Oilseeds Research (ICAR-IIOR), Hyderabad, has developed an innovative biopolymer-based Smart Seed Coating Technology that significantly improves seed quality, crop establishment, and resistance to environmental stresses.
The patented technology comes at a time when Indian agriculture is increasingly challenged by climate change, erratic rainfall, drought, temperature fluctuations, soil degradation, and emerging pest and disease threats. Since seed quality plays a critical role in determining crop productivity, enhancing seed performance during the early growth stages has emerged as a cost-effective strategy for improving farm output.
The Smart Seed Coating Technology uses biodegradable biopolymers to form a multifunctional protective layer around seeds. This coating acts as a delivery platform for beneficial microorganisms, nutrients, micronutrients, crop protection agents, and plant growth-promoting compounds, ensuring targeted support at the seed-soil interface.
According to ICAR-IIOR, the technology creates a favourable microenvironment that promotes faster germination, stronger seedling growth, better root development, and enhanced tolerance to both biotic and abiotic stresses during the crucial crop establishment phase.
Field demonstrations conducted under farmer conditions have produced encouraging results. Trials in Telangana showed that groundnut and soybean crops recorded yield increases of nearly 30 percent compared to conventional farming practices, demonstrating the technology’s potential to improve both productivity and profitability.
The benefits have also been observed across a wider range of crops. Multi-location trials under the All India Coordinated Research Project (AICRP)-Seed covering soybean, maize, groundnut, chickpea, cotton, mustard, and pigeon pea reported productivity gains ranging from 12 to 37 percent over untreated seeds, alongside improved seedling vigour and crop establishment.
Researchers noted that the innovation is particularly valuable for rainfed agriculture, which accounts for a significant share of India’s cultivated area and remains highly vulnerable to delayed monsoons, moisture stress, poor soil conditions, and pest pressures. By protecting seeds and young seedlings during their most vulnerable stages, the technology can help reduce production risks and improve crop resilience.
Unlike conventional seed treatments that typically address a single issue, the ICAR-IIOR platform integrates multiple beneficial inputs into one seed treatment. The technology can be customised for cereals, millets, pulses, oilseeds, fibre crops, fodder crops, vegetables, spices, and horticultural crops, making it suitable for diverse farming systems across the country.
The innovation aligns with national priorities focused on sustainable agriculture, climate resilience, improved seed systems, and greater resource-use efficiency. Scientists believe that wider adoption could contribute significantly to higher agricultural productivity, reduced input losses, and improved nutrient and biological-use efficiency.
ICAR-IIOR scientists emphasized that future agricultural growth will increasingly depend on technologies that maximise the effectiveness of every input used by farmers. Smart Seeds, they said, offer an integrated solution by delivering protection, nutrition, and biological support precisely where and when crops need them most.
To accelerate adoption, ICAR-IIOR is encouraging partnerships with public and private seed systems. State Seed Development Corporations, the National Seed Corporation, cooperative seed federations, Farmer Producer Organizations (FPOs), seed processing units, seed hubs, seed entrepreneurs, and private seed companies are expected to play a key role in scaling up the technology and ensuring quality-enhanced seeds reach farmers across the country.
The institute is also continuing research on next-generation seed enhancement technologies involving advanced biopolymers, beneficial microbes, nutrient delivery systems, and environmentally sustainable formulations.
Researchers believe that widespread adoption of Smart Seed technologies can strengthen India’s seed systems, enhance climate resilience, improve agricultural productivity, and ultimately support the livelihoods of millions of farmers.
