Understanding the effect of poultry manure on kaolinite soil properties and the performance of Okra on the amended soil is important for the effective and efficient management of soils for optimum crop production and environmental conservation. The study was carried out to specifically evaluate the impact of poultry manure amendment on soil properties and the performance of okra. About 15 kg of soil samples were collected and put in polythene bags. Poultry manure at the rate of 5, 10, 15, and 20 g was applied. There was no amendment application in the control. Poultry manure was thoroughly mixed and allowed to stay for two weeks before planting. Okra seeds were planted at three seeds per bag and later thinned down to two. They were replicated 8 times 4 thus summing up to a total of thirty-two samples.  The experiment lasted for 3 months. The experiment was arranged in a Randomized Complete block design (RCBD). Soil samples were collected and analyzed using standard laboratory methods and data generated was subjected to analysis of variance (ANOVA). Significant means were separated with the least significant means at the 0.05 probability level. The growth parameters of okra using kaolinite soils with poultry manure gave a significant increase in germination percentage, mean plant height, the mean number of leaves, and mean several branches. This is a rapidly growing technology in environmental management.
