Phosphorus deficiency is the major soil fertility problem limiting forage production in many parts of Africa. The objective of this study was to screen African Trifolium species for dry matter production, nutrient use efficiency and nitrogen fixation potential at different rates of applied Twenty...

Summarizes and discusses the results of an experiment carried out in 1983 with oats and Italian ryegrass on a soil with vertic properties near Debre Berhan area (Ethiopia) to examine the effects of improved drainage and fertilization (N/P).

Reports concentrations of primary and secondary nutrients in the dry matter that were harvested at various times and the removal of the nutrients from an upland soil in the Ethiopian highland in part III. Part IV deals with the concentration and uptake of Na, Mn, Cu, Zn and Fe from the dry matter...

IV. Concentration, micronutrient yields and crop residue quality

Soil fertility is declining in most agro-ecosystems in sub-Saharan Africa, and incorporation of forage legumes into production systems to utilize the nitrogen fixed by the legumes could alleviate the problem, if efficient nitrogen-fixing legumes are used. The amounts of nitrogen fixed by Lablab, ...

Alfalfa or lucerne (Medicago sativa L.) is an important forage legume grown extensively in the world. There have been relatively few investigations on the adaptation of alfalfa to soils found in suitable eco-zones in Africa. In the present investigations, twenty accessions were evaluated for tole...

Tolerance of Medicago sativa L. to aluminium and low phosphorus in soils and nutrient solutions

Although lablab (Lablab purpureus L.) is grown in many parts of Africa relatively little investigation has been done on its adaptation to acid soils, which are generally low in available In the present study, lablab was evaluated for tolerance to acidity and low available P on two Ethiopian soils...
