Abstract
Due to the poor state and low fertility value of soil in Sub-Saharan African, this study assessed the effect of mycorrhization, using Glomus mosseae on the growth of cowpea. The experimental design was randomized, with four replicates per treatment in four blocks. The effect of treatment on plant growth response data (at p˂0.05) was investigated by analysis of variance. There was a favourable and synergistic interaction between mycorrhiza inoculums and successfully colonized plant roots, and G. mosseae treatment resulted in enhanced plant development. The effect of mycorrhiza inoculation on the growth of cowpea was significant (p˂0.05) when compared with cowpea growth without inoculation. Unsterilized soil inoculated with G. mosseae (M+*S- ) had the highest mycorrhizal colonization. The cowpea grown in inoculated soil presented the best result with plant’s height (38%). The growth response observed was in the order of unsterilized soil inoculated with G. mosseae (M+*S- ) > sterilised soil inoculated with G. mosseae (M+*S+ ) (26%) > unsterilized soil without G. mosseae (M-*S- ) (24%) > sterilized soil without inoculation with G. mosseae (M-*S+ ) (12%). The intensity of fresh weight of the cowpea planted after treatment was also in the order M+ *S- (35%) > M+ *S+ (28%) > M- *S- (24%) > M- *S+ (20%) and the treatment was significantly different at (p< 0.05). The result showed that inoculation with G. mosseae improved growth performance of the plant. Hence, this study confirms the positive effect of mycorrhization using G. mosseae in the growth of cowpea.
