In order to observe the effect of aluminium toxicity on plant and soil parameters investigation was carried out on twenty cowpea genotypes grown in pots with four aluminium levels i.e. 0, 20, 40, 60 ppm with three replications following factorial complete randomized design. After five weeks of growth, individual, main effect and their interaction were studied for uptake of Aluminium and Manganese by root and shoot, post-cropping parameters of soil (pH, available P, extractable Al and extractable Mn) were observed. Genotypes of cowpea and aluminium treatments exhibited significant differences for all characters. However, interaction effect was found significant for all studied character except manganese content in soil. The genotypes G2, G3, G5 and G15 were found superior for studied character.
