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...
The low fertility level of some soils of the Western Highlands of Cameroon prompted a study of the response of maize (Zea mays L.) and some major soil chemical properties to liming. The first manufactured local lime “Agri 56” was tested along with 3 imported types (calcitic, slaked, and dolomitic...
Le faible niveau de fertilite des sols des Hauts Plateaux de l'Ouest a suscit6 une etude des r6ponses au chaulagedu mais (Zea mays) et des proprietes chimiques du sol. La chaux produite localement, "Agri 56," a ete testee comparativement a trois types importes (dolomite, chaux vive et carbonate d...
Alley agriculture in Africa. In Alley cropping, food crops are grown in alleys formed by hedgerows of trees or shrubs, preferably legumes. The hedgerows are cut back at planting and at intervals during cropping to provide mulch and manure for crops growing in the alleys, and to prevent shading an...
A field trial was conducted on two P sorptive, basaltic soils commonly used for maize production in Northwestern Cameroon. The objective was to determine the maintenance P rates required for adequate P supply in the soils for maize after initial capital dressing applications of P (0, 22, 44, 88 a...
Field trials were carried out in M'Vuazi, Bas Zaire, to test the response of groundnuts (cv P43), planted sole or intercropped with cassava (cv Kinuani), to lime application. Groundnuts responded significantly to low rates of lime (250-500 kg ha-1). Maximum cost, benefit ratio of 1:7 was obtained...
