Use of Organic-Based Amendments to Ameliorate Aluminium Toxicity in Legume Production on a Typic Paleudalf of South-Western Nigeria

Aluminum (Al) toxicity is a major limitation to leguminous crop production in acidic soils and fertilizer treatment could ameliorate the condition. In this study, direct and residual effects of fertilizers on the growth and yield of cowpea and soybean grown with or without Al treatment were evaluated on an alfisol. The investigation involved a greenhouse (2 kg soil/pot) experiment with two factors: Fertilizer types- (Control, Organic, Inorganic and Organomineral) and Al rates (0, 50, 100 μM AlCl₃) at the Agronomy Department, University of Ibadan, Nigeria. Treatment combinations were replicated three times in completely randomized design, giving 36 experimental units for each crop. Growth parameters (plant height and number of leaves) and biomass yield were determined and data Analyzed using ANOVA while treatment means were separated by Duncan’s Multiple Range Test. High Al rate (100 μM) reduced growth and yield of the crops while moderate application (50 μM) enhanced their performance. Organomineral fertilizer promoted crops’ performance better than the other fertilizer materials while the application of inorganic or organic fertilizers with 50 μM AlCl₃proved most effective. Organic fertilizer had the highest residual effects equivalent to that of organomineral fertilizer applied with 50 μM AlCl_3,confirming that organic based fertilizers could be used to minimize the deleterious influence of Al toxicity on the production of these legumes in acid soils.
