Root rot severely constrains bean (Phaseolus vulgaris L.) production in parts of Western Kenya. Genetic and soil management options were evaluated for an integrated root rot management approach. Four hundred genotypes were progressively screened in the field for resistance to root not over six se...


Otsyina, R.M.Ajanga, SIBuruchara, Robin A.Wortmann, Charles S.[Development of an integrated bean root rot control strategy for Western Kenya]Development of an integrated bean root rot control strategy for Western Kenya

Researchers worked with farmers in eastern Uganda to develop alternatives for soil management using crotalaria (Crotalaria ochroleuca), mucuna (Mucuna pruriens var. utilis), lablab (Dolichos lablab), and canavalia (Canavalia ensiformis) as green manures in short-term fallows. The participatory re...

Lantana camara L., Senna hirsuta (L.) Irwin & Barneby, Tithonia diversifolia (Hemsl.) A. Gray, and Aspilia kotschyi du Petit-Thouars occur naturally in eastern and central Uganda. Trimmings of these species were evaluated for effectiveness in improving soil productivity. The plant trimmings varie...


Kayuki, KCWortmann, Charles S.[Plant materials for soil fertility management in subhumid tropical areas]Plant materials for soil fertility management in subhumid tropical areas

Fallows improved with tree legumes have a potential role in soil fertility management in the sub-humid tropics. In addition to N2 fixation, deep rooting species can be used to redistribute leached nutrients to the topsoil while producing useful woody by-products. Such fallows are not very effecti...


Wortmann, Charles S.Kaizzi, CK[Tree legumes in medium-term fallows: Nitrogen, fixation, nitrate recovery and effects on subsequent crops]Tree legumes in medium-term fallows: Nitrogen, fixation, nitrate recovery and effects on subsequent crops

Bean ( Phaseolus vulgaris check for this species in other resources L.) production in Africa is constrained by edaphic stresses. A pan-African effort, Bean Improvement for Low Fertility in Africa (BILFA), was initiated in 1990 to screen beans for tolerance to several edaphic stresses. In the fir...
