    Banana peel is a nutrient-rich agricultural waste that can be recycled into valuable products, including bio-stimulant nano-fertilizers. In this study, nano-fertilizer was extracted from banana peel, with an alkaline solution facilitating nanoparticle formation. The synthesized nano-fertilizer was characterized using physical and chemical analyses, revealing particle sizes ranging from 18 nm to 54 nm, with the most abundant nanoparticles measuring 39.9 nm and comprising approximately 36% of the sample. Fourier Transform Infrared Spectroscopy (FTIR) was employed to identify polymeric, inorganic, and organic components, with absorption band changes indicating alterations in the nano-fertilizer composition. Analysis showed that the banana peel-derived nano-fertilizer contains tryptophan, urea, proteins, citric acid, chelated potassium, amino acids, and chelated iron. The fertilizer was applied to pea, chili, and tomato plants to evaluate its effects on plant growth and germination. Results demonstrated that the nano bio-stimulant significantly enhanced germination rates and overall growth in all tested crops, highlighting its potential as an effective and sustainable agricultural input.
