This research was carried out in the village of Jediti in Tartous Governorate in the summer season of 2021, as this experiment included (12) treatments, consisting of overlapping the addition of four levels of mineral fertilizer (F0, F1, F2, F3), which are equivalent to (0,50,75 and 100%) of the fertilizer recommendation for maize, respectively. and three levels of local manufactured biochar from the pruning residues of citrus trees (B2, B1, B0), which are equivalent to (0, 1, 2%) by weight of the soil, respectively. In this soil, a crop of yellow corn, Ghouta 82, was planted. The results showed a positive effect of adding biochar alone or with mineral fertilization on the values of growth indicators for maize, Meanwhile the significant increase in plant wet and dry weight 468.3 and 129.3 g, plant height 186.07 cm, leaf surface index 3.33, ear length 24.73 cm, number of hairs per plant 2.22 area index t was observed when applied B₂F  compared with control B₀F₀.

Key wards:  Zea  mays,  Biochar, Mineral fertilizer, Recommended fertilizer equation.
