Potential rotation crops for replacement of natural soil regeneration in tropical agriculture were grown in nematode infested soil following Celosia argeniea. The aggregate nematode population mean was one-third the preplant mean after six months. Meloidogyne incognita juvenile soil populations w...

The cassava diseases of major economic importance in Africa are cassava mosaic, bacterial blight, and anthracnose, and the major cassava pests are cassava mealybug and green spider mite. Methods of screening cassava breeding material for resistance to the diseases and pests in the light of factor...

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 an...
