Longterm alley cropping with four hedgerow species on an Alfisol in southwestern Nigeria effect on crop performance, soil chemical properties and nematode population por Kang, B.T., Caveness, F.E., Tian, G., Kolawole, G.O.

“…A longterm alley cropping trial was undertaken on an eroded Oxic paleustalf in the forest-savanna transition zone of southwestern Nigeria from 1981–1993. Two nitrogen fixing hedgerow species (Gliricidia sepium and Leucaena leucocephala) and two non legume hedgerow species (Alchornea cordifolia and Dactyladenia barteri) were used in the trial compared to a control (with no hedgerow) treatment. …”

Utilization of rock phosphate by crops on a representative toposequence in the northern Guinea savanna zone of Nigeria: response by Mucuna pruriens, Lablab purpureus, and maize por Vanlauwe, Bernard, Nwoke, O.C., Diels, J., Sanginga, P., Carsky, R.J., Deckers, J., Merckx, Roel

“…The ability of Mucuna pruriens (L.) var utilis (Wright) Burck and Lablab purpureus L. to use P from RP and the changes in selected plant and symbiotic properties and in the soil available P and particulate organic matter (POM) pool as affected by the addition of RP were measured for a set of soils on a representative toposequence (‘plateau', ‘slope' and ‘valley' field) in the Northern Guinea savanna zone of Nigeria. At 18 weeks after planting (WAP), Mucuna accumulated significantly more N and P in the total biomass in the plots treated with RP compared to the plots without RP addition on all fields. …”
