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...

It has always been difficult to find forage legumes with the production characteristics that can help maximise animal performance, and that are also adapted to the alternating wet and dry seasons of the subhumid zone of africa. Among the characters in demand are drought tolerance, good herbage pr...

An experiment conducted to assess the nature of nutrient problems with a view to improving the performance of Verano stylo at the ILCA site (Kaduna). Shows the rates of nutrient application, composition and drymatter yields by varying nutrient additions and in two growing seasons. Also shows P an...

Reports the response of two stylo cultivars, viz, stylosanthes hamata cv verano and stylosanthes guianensis cv cook to 'Kanwa' - a naturally occuring salt traditionally used as a cattle lick - but which shows the presence of various essential nutrients for plants. Discusses the implications to ag...

Until recently kanwa has primarily been known as a mineral supplement fed to traditionally managed cattle in central and northern Nigeria. Preliminary studies carried out by ILCA's Subhumid Zone Programme in 1984 indicated its potential as an economically attractive source of plant micronutrients...
