Abstract: Field experiments were carried out during the 2015/2016 dry season at the Teaching and Research (fadama) farm of Kebbi State University of Science and Technology, Aliero, to study the effects of organic and inorganic fertilization on the performance of maize (Zea mays L.) at Jega, Sudan Savanna of Nigeria. Treatments consisted of six (6) soil amendments, each designed to supply the recommended dose of 120 kg N ha-1 using a compound fertilizer NPK [15:15:15], farm yard manure (FYM) and six-month old poultry manure (PM) from an automated battery cage system. Result shows that plant height at 10 WAP, number of leaves, Leaf area index (LAI), Mean cob weight, grain weight per cob, 100-seed weight and Total yield were significantly increased when the recommended nitrogen dose of 120 kg N ha-1 was applied using 100% NPK (800 kg NPK [15:15:15] ha-1) or a combination of NPK and PM at 50:50 ratio. Based on the results of this study, it was concluded that the integration of organic and inorganic soil amendments in form of NPK compound fertilizer and poultry manure at 50:50 ratio could be adopted for higher Maize yield, considering the complimentary role of poultry manure in improving the physical quality of the soil.
