Four factorial trials were conducted with yam (Dioscorea rotundata Poir.) at Ibadan, Nigeria from 2013 to 2015, investigating effects of (1) tillage (2) fertilizer (3) intercropping (4) yam plant densities. Yam tuber yields varied between years (2013: 16.44 Mg ha−1; 2014: 10.08 Mg ha−1; 2015 26.6...

Experiments were conducted to investigate the potential allelopathic effects of Acioa barteri, Cassia siamea, Gmelina arborea and Flemingia macrophylla leaf material on the germination of maize and early growth of cassava cuttings. Incubation of maize seeds with freshly added G. arborea and C. si...

Greenhouse and field studies were conducted to determine the effect of earthworm casts on the production of maize and cowpea. In pot experiments with mixtures of soil and casts, shoot and root dry matter (OM) of maize and cowpea increased with increasing proportion of casts. Shoot OM of cowpea an...

The impact of land use (unfertilized continuous maize cropping, unfertilized and fertilized alley cropping with maize, Gliricidia sepium tree fallow, natural fallow) on the soil organic matter (SOM) status and general soil fertility characteristics were investigated for a series of soils represen...

Maize was relay cropped with the cover crops Mucuna pruriens or Pueraria phaseoloides for between 1 and 7 consecutive years in three sites, Ngoungoumou, located in an area of low land use intensity (LUI), about 100 km away from the next major market, and at Evendissi and Andok, in a medium LUI ar...

We evaluated if cropping maize immediately after plantain is affected by the previous plantain systems and if tillage or N fertilizer would affect maize growth and grain yield and soil physical properties. The on-farm experiment was conducted at Mfou in the central Cameroon on a clayey, kaoliniti...

Two methods of intensifying crop production in ‘no-external-input’ slash and burn crop fallow rotation systems: increased crop density and increased cropping frequency, were tested on an Ultisol in southern Cameroon. Two common fallow types, secondary forest (forest fallow) and young...

Result of long time alley cropping trials show that the inclusion of N2- fixing hedgerow species maintain higher levels of soil fertility than control treatment (no hedgerow) on high base status soils in the humid zone. Hedgerows contribute to nutrient cycling and higher faunal activity. With goo...
