A laboratory -field experiment was conducted in one of the nurseries in the city of Diwaniyh for the agricultural Season 2021-2022 to study the effect of biologically prepared zinc nanoparticles. Nano zinc prepared from zinc acetate solution that Contains in molar ratios (0,1,2,3 mole) using extract of banana peels and raphanus root of the growth and germination of seedlings and some growth indicators, active ingredients of calotropis procera. completed the experiment with CRD design and three replications in a factorial organisation (2 x 4 x 3) and a LSD squared least parsing test was used in comparison. The averages are at probability level 5%.

The seeds planted in Petri dishes after soaking them in previously prepared solutions for 20 minutes. Then look measurements related to the seedlings after germination, and then the seedlings transferred to pots until reaching the vegetative growth stage.
