This study was conducted to formulate organic liquid fertilizers using selected plant materials i.e., Tithonia diversifolia, Mikania scandens, Chromolaena odorata and Gliricidia sepium with selected organic wastes to compare the efficacies of foliar and soil-applications over the growth of leafy vegetables; Basella alba and Centella asiatica. Selected plant materials were allowed to decompose for two months. Fertilizers were foliar and soil-applied separately on C. asiatica and B. alba in pot trials. Fertilizer formulated with decomposed plants + fish waste treated with C. Papaya significantly recorded the highest N (0.57%), P (0.06%) and highest growth of C. asiatica and B. alba over both soil and foliar applications. Formulated such novel fertilizers can be used in organic farming to reduce the adverse impacts of chemical fertilizers.
