Abstract
A pot experiment was set up to evaluate the influence of treated palm oil mill effluent (POME) on the yield of soyabean (Glycine max). The study consisted of four (4) treatments (0m3/ha, 30m3/ha, 90m3/h and 110m3/ha). Ten kilograms of air-dried soil was measured into plastic buckets. Soyabean variety TGX-1448E was used in the trial. Each treatment was replicated 6 times and arranged in a completely randomized designed (CRD). Data collected were subjected to analysis of variance and least significant difference (LSD) was used for separating the means. Results obtained from this research showed that the growth of soyabean (number of leaves, number of branches, plant height and stem girth), increased significantly with increasing rate of POME applied. At 45 days after planting, nodule parameters (number of nodules, nodule weight and nodule effectiveness) increased significantly with increasing rate of POME. Treatment 110 m3/ha had the highest nodule number (8.0), heavier nodule weight (0.007g) while control had the highest nodule effectiveness (138.72). Application of POME at 110 m3/ha also produced more pod numbers (22.16), pod weight (5.11g), 100 seed weight (14.73g) and total biomass production (9.77g). There was also significant difference in the uptake of nitrogen, phosphorus and potassium. The uptake of nutrients increased with increasing rate of POME. Treatment 110 m3/ha had the highest value (N = 4.05%; P = 0.39% and K = 0.39%). From the results obtained in the research, it can be concluded that POMA, at 110m3/ha) gave the highest value in terms of soybean yield in the study area.
