A greenhouse experiment was conducted to investigate the effects of NPK, poultry manure, and organomineral fertilizer on the growth and nutrient concentration of Moringa oleifera leaves. The experimental design was completely randomized design (CRD) with four treatments replicated three times. Data collected were analysed using descriptive statistics and ANOVA at . Growth parameters measured include number of leaves per plant, plant height (cm), and stem girth (mm). The application of poultry manure increased the height, number of leaves, and stem girth of moringa compared to the application of NPK and organomineral fertilizer while the control had the least growth. Poultry manure, NPK, and organomineral fertilizer were 66%, 62%, and 39% higher in number of leaves than the control at eight weeks after planting. The application of poultry manure significantly increased the nutrient content of moringa leaves compared to other sources of fertilizer applied. The results shows that the application of poultry manure significantly improved the growth and nutrient content of moringa; however, further field trial is suggested. 1. Introduction Moringa oleifera originated from the foothills of the Himalayas in Northwestern India and is cultivated throughout the tropics [1]. Moringa can be cultivated in a wide range of soil types but grow best in well-drained loam to clay loam soil with slightly acidic to neutral pH however, it cannot withstand prolonged water logging. Moringa is very useful in the following areas; as alley cropping, animal forage, biogas, domestic cleaning agent, green manure, gum, medicine, ornamental plants, and water purification. Moringa leaves, seeds, and roots are also use in treating diseases like lung diseases, hypertension and skin infection [2, 3]. Moringa is nutritional and rich in vitamins and minerals. Moringa leaves are the most nutritious part of the plant, being a significant source of vitamin B6 vitamin C, and provitamin A as beta carotene, magnesium, and calcium [4]. However, Moringa still remains unpopular in Nigeria despite its acclaimed economic values and importance; very little research has been done on this plant, although it is widely used by the rural poor as a food resource [5]. Land degrading is one of the major impediments to agricultural productivity. This is manifested in the loss of soil fertility, desertification, and destruction of the soil structure [6]. Due to the implication of land degradation on agronomic productivity and the environment, it becomes necessary to proffer means to minimize it effects. Ultisols
