The study was conducted at Abakaliki to determine the changes in selected soil physical properties and maize yields as affected by animal wastes application in Abakaliki southeastern Nigeria in 2014 and 2015 cropping seasons. The experiment was laid out in Randomized Complete Block Design with four treatment replicated five times. The treatments were poultry droppings at 5 tha-1 (PD), cow dung at 5 tha-1 (CD), mixture of PD + CD at 5 tha-1 and control (C) – non application of amendment. Bulk density, total porosity, moisture content, aggregate stability and mean weight diameter were determine in the laboratory using appropriate procedure while plant height, leaf area index and grain yield were also, measured in the field using recommended methods. The results showed positive changes in selected soil physical properties and maize yield in the two cropping seasons with the application of animal wastes. Also, improvement in soil physical properties and maize yields were higher in the second cropping season when compared to the first cropping season. Poultry dropping is recommended for farmers to use as fertilizer in maize production because plots treated with poultry droppings recorded the highest maize grain yield in the two cropping season than other treatments.
