Double hedgerows of two leguminous multipurpose trees Gliricidia sepium (Jacq.) Walp. and Cassia spectabilis DC. were established in highly eroded, low organic matter, acid uplands in northern Mindanao, Philippines. Alleyways were grown with upland rice Oryza sativa L. and fertilised with G. sepium ...

Efforts to overcome declining soil fertility on smallholder farms in western Kenya must be consistent with the reality of low utilization of inorganic fertilizers. Likewise, organic inputs alone cannot supply adequate nutrients. The use of two organic resources, Tithonia diversifolia (tithonia) and ...

Two-year trials conducted by farmers in Busia, Western Kenya, using extracts of Tithonia diversifolia (combined with Melia azedarach, Cassia spectabilis, C. siamea, sisal [Agave sisalana], Vernonia amygdalina and tobacco) to protect crops from termite [Isoptera] attack are described. A termite trap ...

The results are reported of experiments carried out at the upland research site of the International Rice Research Institute at Claveria, northern Mindanao, Philippines, from July 1987 to 1991. Single and mixed species double hedgerows of the 2 tree species were established in July 1987 as 4-m...

A review. Alley cropping is being widely tested in the tropics for its potential to sustain adequate food production with low agricultural inputs, while conserving the resource base. Fast growth and N yield of most trees used as hedgerows in alley cropping is due greatly to their ability to fix N₂...

Forty-nine accessions of multipurpose trees with potential for agroforestry use, and belonging to 37 species from Africa, Australia, South and Central America, Italy and India, were planted at Makoka, Malawi, on a ferric lixisol at 1030 m altitude, with unimodal rainfall (average 1044 mm per annum) ...

Finding methods to reach resource-poor farmers with suitable agricultural technologies has recently become important, and involvement of the resource-poor farmers themselves in a participatory research (FPR) approach has increasingly been emphasized. This paper (a shortened version of one to be...

In greenhouse trials, inoculum concn of 1.0 × 10⁵ spores/ml of A. cassiae controlled 100% of Cassia obtusifolia, 1.0 × 10⁶ spores/ml was required to achieve 100% control of C. occidentalis. Highest control (25%) of C. spectabilis was achieved with 1.0 × 10⁶ spores/ml. In field plots of soyabeans...

An agropastoral project in Rwanda is used to illustrate the ecological intensification approach to soil conservation. Trees and shrubs such as Grevillea robusta, Albizia versicolor, Croton macrostachys, Acrocarpus fraxinifolius, Cassia spectabilis, Cedrela odorata, Casuarina equisetifolia,...
