Study finds nano-fertilizers enhance rosemary yield and oil quality

Plant scientists from University of Hyderabad, in collaboration with partner institutions, have developed a method to enhance rosemary plant growth and essential oil quality using nanosized macro and micronutrient fertilisers.

The research paper, published in Industrial Crops & Products, shows that foliar application of these nanofertilizers — requiring only 20-30% of conventional fertilizer dosages — can improve plant biomass, root and shoot development, and essential oil yield. By converting fertilizers into nanosized particles through precision milling, nutrient uptake efficiency increased, boosting key compounds like 1,8-cineole.

The study was led by Appa Rao Podile of Department of Plant Sciences and VVSS Srikanth of School of Engineering Sciences and Technology. The breakthrough offers a sustainable model for eco-friendly agriculture with potential applications across diverse commercial crops.
