Effects of methods of seedbed preparation and mulching on the growth and yield of white yam (dioscorea rotundata) on an ultisol in south-east Nigeria por Maduakor, H.O., Lal, R., Opara-Nadi, O.A.

“…Effects of ridge and flat planting of yam, with and without surface mulch, on soil moisture and temperature regimes, root and shoot development, tuber yield and yield components were investigated for an Ultisol near Port Hartcourt in southeast Nigeria. Mulching slightly improved soil moisture regime and decreased the maximum recorded soil temperature at 5 cm depth by 2–3°C early in the season. …”

Long-term integrated soil fertility management in South-western Nigeria : Crop performance and impact on the soil fertility status por Vanlauwe, Bernard, Diels, J., Sanginga, Nteranya, Merckx, Roel

“…Crop response, tree biomass production and changes in soil fertility characteristics were monitored in a long-term (1986–2002) alley-cropping trial in Ibadan, Nigeria. The systems included two alley cropping systems with Leucaena leucocephala and Senna siamea on the one hand and a control (no-trees) system on the other hand, all cropped annually with a maize–cowpea rotation. …”
