Abstract: The current pot experiment was carried out at the Experimental Farm of Environment and Bio-Agric. Dept., Fac. of Agric., Al-Azhar Univ., Cairo, Egypt, during 2017/2018 and 2018/2019 seasons for evaluating the effect of water types, fertilization treatments and organic extracts foliar spray on the growth, yield characteristics and chemical analysis of eggplant. The experiment arranged as a factorial completely randomized at 18 treatments and five replications. The treatments were as follows; water irrigation types (W); tap water (W1), gray water (W2), mixture of gray water and tap water in 1:1 (v:v) ratio (W3), fertilization types (F): NPK recommended dose (F1), 100% compost as recommended N (F2), and organic extract: without extract as a control treatment (WE), azolla extract (AE) at 500 ml / 100 g fresh material and moringa leaf extract (MLE) at 500 ml / 100 g fresh material, as a foliar spray. W1-plants revealed maximum growth and yield traits. But W2-plants recorded the highest nutrients content (N, P, K, Ca, Mg and Fe). F1-plant achieved the highest productivity and chemical analysis. While the highest Mg and Fe content was given by F2-plants. MLF gave the highest values of all studied characters except Fe content was given by AE application for both seasons. The treatment of W1 × F1 × MLE gave the highest values of total yield/plant and carotenoids content. But highest Fe value was given by W2 × F2 × AE treatment.
