The study was conducted in 2015 planting season at teaching and research farm, Enugu State University of Science and Technology, Enugu State Nigeria; the study investigated the effects of different rates of sewage sludge (0, 2, 4, 6 and 8 t/ ha) on soil physicochemical properties, growth and yield of Bambara groundnut (Vigna subterranean) in a degraded Ultisol, Agbani, Enugu, South Eastern Nigeria. The treatments were laid out in randomized complete block design with replications. Physicochemical properties of soil, SOM, N, CEC, and available P) were analyzed using standard analytical laboratory methods. The obtained results from the laboratory revealed that application of sewage sludge altered a positive change on soil physicochemical properties in all amended plots than the control plots. The soils from plots treated with 8t/ha of sewage sludge had the highest pH value of 6.9 while .. View more»
