Therefore, products obtained from different sources can be used as fertilizer. Banana, pomegranate and bitter orange contain important nutrients that can be recycled into useful materials for reuse. Nano fertilizer is one of them. Therefore, the nano fertilizer mixture of biostimulants was extracted from banana peels, pomegranate and bitter orange. This study was conducted to determine the effect of liquid nano fertilizer on plant growth. The extract of the nano-fertilizer underwent physical and chemical analyzes to characterize the fertilizer as well as the obtained nano-fertilizers were characterized by transmission electron microscope as the component size ranged from 14.6 to 65.6 nm, and the graph shows that the main nanoparticles were 30 nm with an average percentage of 18%, while the The nanoparticles of 90 nm were small in size with an average of 2%, this is for the nano fertilizer extracted from pomegranate peels while the fertilizer extracted from banana peels ranged in size of the component. From 26.7 to 100.3 nm, the graph shows that the main nanoparticles were 60 nm with an average percentage of 4%, while the 100 nm nanoparticles were small with an average percentage of 1%. The graph shows that the main nanoparticles were 72 nm. With an average percentage of 49.9% while the 92nm particles were small with an average percentage of 9.9%. Green nanotechnology is a promising technology towards reducing environmental pollution and sustainable agriculture.entext::thesis::master thesis
