Field experiments were conducted to assess the influence of different rates of poultry manure on soil properties, growth and yield of maize at Teaching Research and Farm, Federal University Wukari, Taraba State, Nigeria. Four treatments were used in the experiment (0 t ha-1, 5 t ha-1, 7.5 t ha-1 and 10 t ha-1 of poultry manure) used Randomized Complete Block Design (RCBD) replicated three (3) times. The results obtained from the experiment showed that application of poultry manure increased soil pH, available P, available Ca, organic C, CEC, and total N. the rate of 10 t ha-1 recorded the maximum plant height, least numbers of days to 50% (60.72 and 61.56) and highest grain yield (3.12 and 3.18 t ha-1) in the two cropping seasons. Hence from the field experiment, it can be inferred that the application of 10.0 t ha-1 of poultry manure can be used for soil sustainability, growth and yield of maize.
