Fashola, O.Imolehin, E.D.Wakatsuki, T.[Water management practices for sustainble rice production in Nigeria]Water management practices for sustainble rice production in Nigeria

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...

A field study of cowpea, soybean and maize was made at Ibadan, Nigeria, to determine the uptake of mineral nutrients and quantities removed in crop residues and seed. Concentrations of N, the major cations (K, Ca, Mg and Na) and major anions (P, S and Cl), and the micronutrients (Fe, Mn, Zn and C...

Crop response, tree biomass production and changes in soil fertility characteristics were monitored in a long-term (1986–2002) alley-cropping trial in Ibadan, Nigeria. The systems included two alley cropping systems with Leucaena leucocephala and Senna siamea on the one hand and a control (no-tre...

Banana is the primary food crop in Uganda, but yields are low due to a complex of abiotic and biotic constraints. However, quantitative information on the importance, interactions, and geographic distribution of yields and constraints is scanty. We monitored yields, biotic and abiotic constraints...

In southern Benin, the legume cover crop ´ Mucuna pruriens var. utilis has been widely promoted for soil fertility improvement. Recent findings have shown, however, that the majority of farmers have not adopted it, and that alternative technologies are needed that are both attractive to farmers a...

The potential of alley cropping systems supplied with a limited amount of fertilizer to restore crop productivity on a degraded site and to maintain crop productivity on a recently cleared, non-degraded site on ‘terre de barre' soils in Southern Bénin was investigated from 1994 to 1996. Leucaena ...

Restoration and maintenance of soil fertility on terre de barre soils in Benin Republic

Microarthropods, such as soil mites (Acari) and springtails (Collembola), with body width between 0.08 mm and 0.5 mm play important roles in soil fertility maintenance through their regulatory activities in decomposition and nutrient turnover. Observations were made at IITA, Ibadan, southwestern ...

Changes in agriculture and rural livelihoods in Africa are often attributed to the HIV epidemic. While acknowledging that the epidemic has devastated many families and communities because of excess morbidity and mortality, this review explores other causes of change in agriculture practices and p...
