Phosphorus management with special reference to forage legumes in sub-Saharan Africa
A study conducted to develop a classification for Ethiopian clovers based on the performance and phosphorus requirement which has potential for selecting accessions from the rest of the ILCA germplasm suitable for different levels of soil The effects of different P levels on the growth and N and ...

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...

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, ...

Pot trials and laboratory phosphorus (P) sorption studies were conducted to evaluate the response of seven Ethiopian clover species (T. decorum, T. steudneri, T. quartinianum, T. rueppellianum, T. schimperi, T. tembense, and T. subterraneum) to applied P and further to determine the critical exte...

Although the majority of soils in Africa are P deficient, the high cost of conventional water-soluble P fertilizers limits their use by resource-poor farmers. Rockphosphates are a low-cost alternative. The effect of Egyptian rockphosphate (ERP) from two sources, applied at 50 kg P ha-1, on annual...
