Inventor(s) include Durgesh Kumar Maurya; Aniketkumar L. Bijewar; Aishwarya Rajkumar Ingole; Oinam Bombayshwori Devi; Addya Singh; Arvind Kumar; Dr. Ram Ashish; Dr. Satyarath Sonkar; Ragini Verma; and Nisha Yadav.

The application for the patent was published on June 5, under issue no. 23/2026.

According to the abstract released by the Intellectual Property India: "Low nutrient-use efficiency and rapid fertilizer losses remain major constraints in arid cereal production, where sandy soils, high temperature, low organic matter, and irregular rainfall reduce fertilizer availability during critical crop-growth stages. This paper proposes a bio-polymer coated controlled-release nano-fertilizer designed for arid zone cereals such as pearl millet and sorghum. The formulation consists of nano-sized NPK nutrient cores coated with a biodegradable chitosan-alginate-starch matrix to regulate nutrient diffusion, improve moisture retention near the rhizosphere, and reduce leaching losses. A controlled pot and field-style evaluation framework is presented using conventional NPK, uncoated nano-fertilizer, and bio-polymer coated nano-fertilizer treatments. The proposed coated nano-fertilizer showed a gradual nutrient-release pattern, with 78.6% cumulative nitrogen release over 35 days compared with 92.4% release from uncoated nano-fertilizer within 14 days. Under arid soil conditions, the coated treatment improved grain yield by 24.8%, nitrogen-use efficiency by 31.6%, and soil residual nitrogen retention by 22.4% compared with conventional fertilization. The study indicates that biodegradable coating materials can support climate-resilient nutrient management in dryland cereals."
