Track 1-15: Pastures in Integrated Crop/Livestock Production Systems
Description
The low fertility status of most tropical soils has hindered maize production as maize has a strong exhausting effect on the soil. It has been generally observed that maize fails to produce good grain in plots without adequate nutrients (Adediran and Banjoko 2003). Legumes generally are able to fix nitrogen to the soil which the companion crop could benefit from, but usually the nitrogen fixed occurs in insufficient quantities for marginally nitrogen sensitive crops such as maize and hence the required use of fertilizers. Inorganic fertilizers exert strong influences on plant growth, development and yield (Stefano et al. 2004). The use of legumes in mixed cropping systems is one of the traditional soil-fertility maintenance strategies. Legume-cereal intercropping often increases the quantity and quality of residues, which could improve livestock production considerably in addition to benefits in soil fertility but may decrease the yield of the companion cereal crop (Nandi and Haque 1986). Although the beneficial effects of intercropping legumes have been demonstrated by intercropping cereals with a few legumes such as cowpea, lablab, soybean etc, the same cannot be said for all legumes. This study aims at investigating the effect of fertilizer levels and intercropping with bambara nut (Vigna subterranean L.Verdc) on the growth and yield of maize for use as forage.
