Major upland soils in the humid and sub humid zones of West Africa consist of low activity clays (LAC) Alfisols, Ultisols and Oxisols. Alfisols which are less leached and have a high base saturation are more dominant in the sub-humid zone. Chemically they are more fertile, but they have a low str...

Performance of commonly grown agroforestry woody species was assessed at two locations in southern Nigeria, on an Alfisol (Oxic Paleustalf) at Ibadan in the forest-savanna transition zone and on an Ultisol (Typic Paleudult) at Onne in the forest zone, with annual rainfall of 1280 and 2400 mm resp...

Decomposition and nutrient release patterns of prunings of three woody agroforestry plant species (Acioa barteri, Gliricidia sepium and Leucaena leucocephala), maize (Zea mays) stover and rice (Oryza sativa) straw, were investigated under field conditions in the humid tropics, using litterbags of...

Effects of application of prunings of three woody species (Acioa barteri, Gliricidia sepium and Leucaena leucocephala), maize (Zea mays L.) stover and rice (Oryza sativa L.) straw as mulch on maize were studied on an Alfisol in southern Nigeria in 1990 and 1991. Maize dry matter and grain yield w...

On a Ferralic-haplic Acrisol (terre de barre non degradee) in Southern Benin Republic, four years after the establishment of the hedgerows, yields of maize and cassava alley cropped with Leucaena leucocephala and Cajanus cajan were no better than those in control plots without hedgerows. Reduced ...

The IBSNAT (Internal Benchmark Sites Network for Agrotechnology Transfer) CERES-Maize model, which stimulates a sole crop of maize, was tested during the 1990 and 1991 growing seasons at Ibadan in southwestern Nigeria. The maize model is designed to simulate plant physiological processes (nutrien...

An equation was developed for calculating a plant residue quality index (PRQI) in the (sub-)humid tropics using the C/N ratio and lignin and polyphenol concentration of plant residues. Among 18 plant species tested, there was a large variation in PRQI. The PRQI was correlated with the decompositi...
