Background and Objective: The effect of manure-induced factors on soil electrical conductivity (EC) and Corchorus olitorius L. when manures were applied at high rates had received little research attention. This study evaluated the effects of animal manures and their residuals on soil EC and Corchorus olitorius L. dry matter yield (DMY)/plant. Materials and Methods: The experiment was a randomized complete block design with three replications. The data collected were subjected to Analysis of Variance using a Statistical Analytical System. Cured cattle, goat and poultry manures were applied at 0, 5, 10, 20, 40, 60, 80, 120 and 150 t/ha once at the onset of the first cycle and N₁₅P₁₅K₁₅ at 0.4 t/ha per cycle. Soil samples collected bi-weekly in each cycle were analyzed for EC using standard procedures. Six weeks after planting (6 WAP) in each cycle, Corchorus olitorius L. DMY/plant was determined. Data were analyzed using ANOVA (Statistical Analytical System 22) and treatment means were compared using Duncan Multiple Range Test at a 5% probability level. Results: Across cycles, soil EC content decreased. Percentage increase of soil EC in the first, second and third cycles over the control, were 794, 667, 455; 660, 966, 430 and 675, 232, 205% for cattle, goat and poultry manure treatments, respectively. The Corchorus olitorius L. DMY/plant at the second and third cycles were higher than the first cycle by 33%. Incorporation of animal manures above 60 t/ha reduced Corchorus olitorius L. DMY/plant at the first cycle but improved the parameters at the second and third cycles. Conclusion: Consequently, the addition of cattle, goat and poultry manures above 60 t/ha increased the soil EC but decelerated Corchorus olitorius L. DMY/plant at the first cycle but their residual effects improved the DMY/plant of Corchorus olitorius L.]]> https://scialert.net/abstract/?doi=ijss.2025.1.15 10 June, 2026
