Journal Article 1999

Autor: Lupwayi, N.Z. Haque, I.

A litter bag technique was used to study the decomposition and release of N, P, K, Ca and Mg from Leucaena leucocephala and L. pallida prunings and cattle manure in a hedgerow intercropping trial conducted in the Ethiopian highlands. Hedgerow inter-cropping (also called alley cropping or alley fa...

Journal Article 1998

Autor: Lupwayi, N.Z. Haque, I.

The N.P.K. Ca and Mg release patterns of the leaves of four accessions of Sesbania species and two accessions of Leucaena species were evaluated in a 5-week laboratory incubation. Leaves of these leguminous trees, applied at an equivalent rate of 3 t dm ha-1, were significant sources of N, K and ...

Journal Article 1999

Autor: Lupwayi, N.Z. Haque, I. Saka, A.R. Siaw, D.E.K.A.

The effects of Leucaena leucocephala and L. pallida prunings and cattle manure on maize nutrient uptake and yield were investigated in a hedgerow inter-cropping trial in the Ethiopian highlands. Hedgerow inter-cropping (also called alley cropping) is an agroforestry system in which trees are grow...

Journal Article 1999

Autor: Lupwayi, N.Z. Haque, I.

Balances between nutrients applied or mineralized and nutrients removed in maize grain and stover were calculated in a hedgerow intercropping experiment in which Leucaena leucocephala and L. pallida prunings and cattle manure were applied. Hedgerow intercropping (also called alley cropping) is an...

Conference Paper 1992

Autor: Haque, I.

Crop livestock production systems in Africa are constrained by wide fluctuations in the quality and quantity of feed resources during the year and by the low availability of nutrients, especially nitrogen and phosphorus, in most soils, which threatens the sustainability of primary production. In ...
