Abstracts |
A field experiment with cowpea (Vigna unguiculata) cv. Ife Brown was conducted in 1995 in a heavy textured loamy sand Iwo series soil and in 1996 in a light textured soil of the same series to determine its response to single or dual inoculation with arbuscular mycorrhiza (AM) fungus, Glomus mosseae, and a mixture of Bradyrhizobium strains IRj 2184A and IRc 256. The single and dual inoculation increased the plant height, nodule number and weight, dry matter accumulation of shoot, percent nitrogen (N) and phosphorus (P) in plant tissue, and the percent N2 derived from atmosphere when compared with the inoculated control in the 2 years. Grain yield was enhanced by 20% due to the dual inoculation in 1995 and only 1% in 1996. The rate and intensity of AM infection were significantly improved by inoculation. |
