India’s agricultural sector faces a persistent challenge: despite ranking as the world’s second-largest producer of horticultural crops, substantial quantities of fresh produce spoil before reaching consumers. Addressing this critical gap, Dr. Ramakrishna A., Senior Scientist at DRDO-DFRL, has pioneered a breakthrough preservation system that could reshape how farmers and vendors handle perishable goods.
His innovation, termed Krishi Kavach, represents years of expertise channeled into a single purpose: extending produce freshness without conventional refrigeration. During an extensive discussion with the UI NEWZ team, the veteran scientist shared perspectives on the technology’s genesis, its practical applications, and the broader vision for agricultural transformation.
Q: What motivated you to develop this preservation technology, and how did your defense research experience shape its creation?
Dr. Ramakrishna explained that his three-decade-plus tenure at DRDO-DFRL provided unique exposure to extreme preservation challenges. Working on food systems for armed forces personnel deployed in harsh environments, from Himalayan peaks to desert expanses and naval vessels, demanded innovative thinking about maintaining nutritional value without standard infrastructure.
His portfolio included developing indigenous retort processing methods for ready-to-eat military rations and specialized flexible pouches designed for field conditions. Additional projects encompassed solar-powered dairy product makers, rechargeable food warming systems, and anti-freeze storage solutions for high-altitude deployments.
These diverse experiences crystallized into a realization: technologies refined for military logistics could address civilian agricultural needs. The scientist’s doctoral research on breathable materials for vegetable storage provided the foundational knowledge, which he pursued intensively post-retirement, driven by both technical challenge and passion for solving real-world problems.
Q: What specific agricultural challenges does your technology address?
The response was direct: India loses enormous agricultural value between harvest and consumption. Drawing from his PhD work on breathable material science, Dr. Ramakrishna focused on creating specialized packaging that could maintain produce quality for extended periods, up to a full month, without electric cooling systems. The material incorporates antimicrobial and antifungal properties embedded within its structure, providing multi-layered protection against degradation.
Q: Can you describe the technical principles behind these preservation bags?
With patent applications currently under review, specific compositional details remain confidential. However, Dr. Ramakrishna emphasized that the material foundation is entirely biodegradable and bio-compostable, aligning with environmental sustainability goals.
He envisions building a consortium involving angel investors and technical partners to scale production and distribution. The scientist noted that individual farmers typically lack resources for sophisticated infrastructure investments, making collaborative funding models essential for widespread adoption, both domestically and in international markets.
Q: How adaptable is this system for different users, from small-scale farmers to export operations or home consumers?
Versatility was designed into the system from inception. The packaging accommodates loads ranging from half a kilogram to 25 kilograms, with dimensions and configurations customizable for specific crops. Whether dealing with delicate berries or robust root vegetables, the shape and size parameters can be adjusted to match the geometric characteristics and handling requirements of different produce types, ensuring optimal protection throughout the distribution network.
Q: What role did agricultural research institutions play in validating your technology?
Dr. Ramakrishna acknowledged support from Gandhi Krishi Vigyan Kendra networks, while highlighting particularly strong encouragement from the Indian Institute of Horticultural Research, specifically mentioning Dr. Dubey’s contributions. Public demonstration at the Krishi Mela agricultural exhibition generated enthusiastic response from both farming communities and end consumers, who recognized its practical utility and potential for improving bulk handling operations.
Q: How do you plan to educate farmers about this cost-effective innovation?
The strategy draws inspiration from Dr. Verghese Kurien’s cooperative model during India’s dairy revolution. Dr. Ramakrishna is establishing partnerships with rural cooperative societies to create nodal distribution and training centers in agricultural villages. These hubs will provide comprehensive facilities for produce cleaning, grading, hygienic packaging, and market linkage, both domestic and international.
Beyond infrastructure, these centers will serve as education platforms where farmers receive hands-on training in cost-effective preservation techniques, fostering sustainable adoption of new agricultural technologies.
Q: What economic transformation could result from widespread implementation?
The scientist presented striking statistics: despite India’s massive horticultural output, only 20-30 percent reaches consumers. The remainder is lost to inadequate post-harvest technology, improper handling protocols, insufficient packaging materials, infrastructure deficits, inefficient transportation networks, and over-reliance on refrigeration.
Refrigeration itself presents problems, chilling effects can diminish micronutrient content in sensitive vegetables. Krishi Kavach addresses these systemic issues by reducing cold storage dependency while providing antimicrobial and antifungal protection through advanced material science.
By dramatically improving shelf life and enabling greater value addition at the farm level, the technology promises direct income enhancement for agricultural producers. This translates to measurable GDP contributions while achieving three concurrent goals: increasing farmer profitability, delivering hygienic, high-quality produce to consumers, and ensuring nutrient-rich supplies reach soldiers stationed in remote areas.
Dr. Ramakrishna’s work represents a convergence of defense research rigor and agricultural pragmatism. As patent processes advance and cooperative networks expand, Krishi Kavach could become a standard tool in India’s effort to minimize waste and maximize value in its massive horticultural sector. The technology stands as proof that innovations born from one context, military logistics, can find powerful applications in addressing civilian challenges when guided by vision and technical expertise.
