Effect of Compost and Mycorrhizal on Growth and Yield of Soybean (Glycine max (L) merill)

A pot experiment was carried out at the University of Agriculture, college of plant science (co-plant) Abeokuta. Nigeria, using the Complete Randomizes Design (CRD) to study the effect of compost and the different species of mycorrhizae on the growth and yield of soybean (Glycine max). Significant differences were observed between the treatments on some growth and yield parameters of soybeans at the vegetative stage and the reproductive stage. This implies that the treatments applied showed different responses to the crop. The crop performed better in the number of branches, canopy spread, number of leaves, leaf area and plant height for growth parameters, while significant differences was observed in seed weight/pot and seed weight/ha for yield parameters. The study concludes that the growth of soybean was significantly enhanced by the combine inoculation of Glomus deserticola (GD) and compost, while the yield was significantly enhanced by the combine inoculation of Glomus mosseae (GM) and compost. Also, higher number of spore count and % root infection was recorded in the combine innoculation of Glomus deserticola and compost.
