The importance of using organic manures for growing plant seedlings and also improving the nutritional status of their growth media for higher productivity is frequently emphasised. Afrormosia elata has a wide range of therapeutic applications, but it is not widely available. Thus, at the Federal College of Forestry's nursery ‘A' in Ibadan, Nigeria, researchers investigated the impact of fish pond sediments (FPS) and decomposed cow dung (DCD) on the early growth of A. elata seedlings. Maintaining pond volume and ecosystem by sediment removal is a beneficial activity for productive fish farming. A. elata seeds were sown in a finely perforated sieve (filled with washed river sand) and seedlings were pricked – out into polythene pots with varying amounts of FPS and DCD 2 weeks after seedling emergence. There were nine therapies and eight replicates in the Fully Randomized Design (CRD) experiment. T1 (2 kg FPS + 2 kg topsoil); T2 (2 kg DCD + 2 kg topsoil); T3 (1.5 kg FPS + 2 kg topsoil); T4 (1.5 kg DCD + 2 kg topsoil); T5 (1 kg FPS + 2 kg topsoil); T6 (1 kg DCD + 2 kg topsoil); T7 (500 g FPS + 2 kg topsoil); T8 (500 g FPS + 2 kg T8 (500 g DCD + 2 kg topsoil), with 2 kg of untreated topsoil serving as a control. Morphological parameters including seedling height, collar diameter, and leaf count, as well as leaf biomass, were measured, and the data was analysed using ANOVA (ANOVA). T3 (1.5 kg FPS + 2 kg TS) outperformed the others in terms of height, leaf area, and leaf biomass, with mean values of 11.02 cm, 21.65 cm2, and 1.16 g, respectively. Despite this, there were no statistically significant differences among the growth parameters examined in this analysis. However, T3 (1.5 kg FPS + 2 kg TS) may be used to accelerate the growth rate of this plant's seedlings.
