The Experiment was conducted during the 2019 season at Salou Station- Deir  Ezzor of the General Commission for Scientific Agricultural Research. This research aims to study the possibility of using organic fertilizers instead of some part of mineral fertilizers. The impact of in-part use of organic fertilization on yield and yield components of Zea Maize crop (Ghouta 82) was studied. A complete randomized block design was applied in which the experiment consisted of 5 treatments with 3 replications: (D0: control, D1: mineral fertilizer 100%, D2: 100% mineral fertilizer +humic acids KOH extract, D3: mineral fertilizer 75% + humic acid KOH  extract, D4: mineral fertilizer 50% + humic acid KOH extracts. Sheep humic acid extracts were added to the crop at a rate of 2.5 ml/l. The results showed that the D2 treatment was the best for both productivity and all the morphological characteristics. The productivity was (7.96) t/ha for D2 treatment compared to the control (3.07) t/ha. The results also showed that there were no significant differences between D1, D3. D3 treatment was the lowest rate of mineral fertilization. It is therefore, treatment D3  can be recommended to minimize the use of mineral fertilizers added to the soil in a situation similar to our experimental conditions.
