The effect of alley cropping with seven combinations of Acioa and Leucaena hedgerows and a control (no hedgerow) treatment on sequentially cropped maize and cowpea was studied in 1985 and 1986. The trial was carried out on an Alfisol in the humid zone of southwestern Nigeria. Hedgerows were estab...

Measurements of incident solar radiation were made in sequentially cropped maize (Zea mays L.) and cowpea (Vigna unguiculata L. Walp.) planted between hedgerows of shrubs in an alley cropping pattern. The incident solar-radiation profile was examined and its effect on crop yield determined. The s...

The effects of tropical earthworms (Eudrilus eugeniae) and millipedes (Spirostreptidae) on the breakdown of plant residues [Acioa (presently, Dactyladenia) barteri, Gliricidia sepium and Leucaena leucocephala prunings, maize (Zea mays) stover and rice (Oryza sativa) straw], with contrating chemic...

Field experiments were conducted with IITA maize (Zea mays L.) composite B at six locations ranging from forest to savannah in the Western State of Nigeria to assess the level of zinc response on sandy Inceptisols. Zinc, as Na2 Zn EDTA, was applied as broadcast application at 0, 1.0, 2.0, 4.0, an...

Phosphorus plays an important role for food crop production in the forest zone of tropical Africa but very little information is available on the phosphate requirement for maize production there. Field trials were, therefore, conducted with maize (Zea mays L.) at two locations on Alfisols in sout...

The initial effectiveness of two rock phosphate samples from Morocco (MRP) and North Carolina (NCRP) was compared with concentrated superhposphate (CSP) in greenhouse using two Alfisols and one Ultisol from southern Nigeria. Under similar pH condition (pH 6), the two rock phosphates were more ef...

The potential of alley cropping maize and cowpea with the giant Leucaena (Leucaena leucocephala (Lam) de Wit) cultivar K-28 was studied on an Entisol (Psammentic Ustorthent) in Southern Nigeria. In this trial the crops were grown in 4 m wide alleys formed by periodically pruned leucaena hedgerows...

Effects of hedgerow species on surface soil physical properties were studied in an on-going trial established since 1981 on an Oxic Paleustalf in southwestern Nigeria. The experimental treatments were Leucaena leucocephala, Gliricidia sepium, Alchornea cordifolia and Acioa barterii hedgerows plan...
