Abstract: A field experiment was conducted on Ain mara, Derna, Libya during the growing season of 2023/2024 to investigate the effect of application combination of Moringa leaf powder and zinc sulfate on growth, yield, and chemical composition of maize cv. “Hybrid 3062”. The experiment consists of 9 treatments (control, 5 MLP+ 0.5 ZnSO4, 10 MLP+ 0.1 ZnSO4, 15 MLP+ 0.1 ZnSO4, 20 MLP+ 0.1 ZnSO4, 25 MLP+ 0.1 ZnSO4, 30 MLP+ 0.1 ZnSO4, 35 MLP+ 0.1 ZnSO4 and 40 MLP+ 0.1 ZnSO4, kg/ha) arranged in Randomized Complete Block Design with three replications. Moringa leaf powder (MLP) and ZnSO4 were applied to soil at during preparing the soil for agriculture. The results showed increasing combination of Moringa leaf powder and zinc sulfate were significant effect of all studied traits, which the treatment of 40 MLP+ 0.1 ZnSO4, kg/ha recorded the higher values of all vegetative growth were studied i.e. plant height, number of leaves / plant, leaf area index and dry weight of shoot, also, increased all yield traits i.e. cob length, cob diameter, number of grains/ cob, number of grains/ raw, 100-grains weight,  grain yield and harvest index, additionally,  increased chemical composition of maize such as nitrogen, phosphorus, potassium, protein, zinc, iron and manganese, followed by treatment of 35 MLP+ 0.1 ZnSO4,  as compared with the control treatment which recorded the lower values of all studied traits during 2025 seasons. In conclusion, the current findings also reveal fundamental new insights into the use of moringa tree leaves for improving soil quality and crop yield. However, the study had several limitations: it was not conducted over multiple years, field trials were not implemented, and the effects of combining MLP with chemical fertilizers were not assessed. Moreover, further research should be carried out under field conditions, over multiple years, and locations to provide conclusive recommendations.
