Background: In the current global landscape, agriculture is heavily reliant on synthetic fertilisers, which places stress on the soil and plant environment. The greatest alternative is nano fertilisers. As a result, the following research was completed.
Methods: In 2021, a pot experiment was conducted at Annamalai Nagar, Faculty of Agriculture, Annamalai University, to investigate the effects of conventional and nano fertilizer on maize growth and yield (Zea mays L.). To analyse maize crop development and yield qualities, the experiment was set up in a Completely randomized block design (CRBD) with two factors and ten treatments: Factor A nano zinc and zinc EDTA and Factor B combined application of nano nitrogen with conventional fertilizers. 
Result: In our investigation results was concluded that combined application 50% N through urea + 50% N through nano urea combined with nano Zn substantially increases plant height 195.80 cm, LAI 1.95, dry matter production 15013 kg ha-1, number of grains cob-1 496, garin yield 8926 kgs ha-1, stover yield 12094 kgs ha-1 and harvest index 42.46.
