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 ...

Phytotoxic effects ofGliricidia prunings were tested on maize seedlings in the laboratory and on maize and cowpea seedlings in the field. In the laboratory test, growth of maize seedlings was significantly depressed by addition of leachate ofGliricidia prunings. In the field, leaf, chlorosis of m...

The effects of five agroforestry woody species (Dactyladenia barteri, Gliricidia sepium, Leucaena leucocephala, Senna siamea andTreculia africana) on the surface aasting activity ofHyperiodrilus africanus were studied in an Alfisol (Oxic Paleustalf) in southwestern Nigeria. Casting activity under...

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...

A study was undertaken to assess the effect of different pruning intervals of Leucaena leucocephala hedgerows on alley cropped maize and cassava. Farmers often delay hedgerow pruning in alley cropping systems due to labor, and financial constraints. It is not clear, however, when hedgerow shading...

Field trials were carried out on a Dystric Nitosol at Calavi in the subhumid zone of southern Benin Republic, West Africa from 1989-1997. A split plot design with four replications was used. There were (our main plots: control (no hedgerow), Leucaena hedgerows, Acacia hedgerows and mixed Leucaena...

Below-ground root competition between Leucaena hedgerow and intercropped maize and cowpea was evaluated on an Alfisol in the humid zone of southwestern Nigeria. Four-meter spaced hedgerows were established in 1983, and trials carried out with sequentially cropped maize and cowpea in 1990 and 1991...

An experiment was conducted in 1990 and 1991 at the International Institute of Tropical Agriculture (IITA), Ibadan, Nigeria to study the role of earthworms in the decomposition of plant residue mulches with different qualities. Five mulches of Dactyladenia barteri, Gliricidia sepium, Leucaena leu...
