Maize (Zea mays L.) is a vital global cereal crop, essential for food security and economic stability. Efficient nutrient management is crucial for enhancing maize yields while minimizing environmental impacts. Conventional urea fertilization faces challenges, including nutrient losses and environmental pollution. This study investigates the potential of carbamide loaded double emulsion as a novel delivery system for maize cultivation. Field experiments, utilizing a Randomized Block Design, evaluated different concentrations of Nano foliar fertilization (carbamide-loaded double emulsion) and conventional urea. Results showed that Nano foliar fertilization, especially at 2%, significantly increased maize plant height and dry matter accumulation, rivaling the effects of conventional urea. These findings highlight the promise of double emulsion technology in optimizing nutrient management, promoting sustainable maize growth, and advancing eco-conscious agricultural practices.
