Aloe vera is a natural product that is now frequently used in the field of cosmetology. Though there are various indications for its use, controlled trials are needed to determine its real efficacy. Therefore this research was conducted to determine the effects of different nitrogen sources on growth, yield and gel composition of Aloe vera. A pot experiment was conducted at screen house of the Faculty of Agricultural Sciences Ladoke Akintola University of Technology Ogbomoso, Nigeria. The treatment comprises of thirteen different Nitrogen fertilizer sources (Urea 62.5 kgN/ha and 125 kgN/ha, NPK 62.5 kgN/ha and 125 KgN/ha, Tithonia 62.5 KgN/ha and 125 kgN/ha, Feedstock 62.5 KgN/ha and 125 kgN/ha, Deep litter 62.5 kgN/ha and 125 kgN/ha, Goat manure 62.5 KgN/ha and 125 kgN/ha) and control. Aloe vera was laid out in a complete randomized design with four replications. The parameters measured and recorded were leaf length, leaf width, plant height, Number of suckers, Number of leaves, leaf thickness, leaf volume and gel composition. After fifteen months of transplanting, the Aloe vera plant was harvested, washed with distilled water and blended and taken to laboratory for analysis. Result showed NPK applied at the rate of 62.5 KgN/ha increased the leaves length, width, thickness and plant height, Tithonia applied at the rate of 125 Kg N/ha increased the number of leaves, Number of sucker, and volume of leaves, it was also observed that the Deep litter at that rate of 125 KgN/ha, NPK at the rate of 125 KgN/ha, Feedstock at the rate of 62.5KgN/ha and 125 KgN/ha increased the phytochemical composition of Aloe vera. In conclusion NPK at the rate of 62.5 KgN/ha is recommended for growth and yield. Tithonia at the rate of 125 KgN/ha is recommended for immune boosting, anti-inflammatory, analgesic, antibacterial and antiviral. While for antiseptic, Deep litter at 62.5 KgN/ha, for antioxidant, Feedstock at 62.5 KgN/ha and 125 Kg/ha and NPK application at 125KgN/ha were recommended for formation of bones and teeth.
