Introduction of cassava leaf silage making to smallholder farmers and its feeding to ruminants in cassava crop growing areas were investigated through laboratory and on-farm feeding trials, extension services and training. This with the aim to evaluate the response of the ruminants on cassava lea...

A three different sites with acid soils in Colombia field trials with cassava were monitored for frequency of VA mycorrhiza. Increasing levels of phosphorus (P) from 0 to 200 kg P/ha had been applied. The fields differed in the composition of species of VA mycorrhizal fungi. At all sites infectio...

A technique to study mycorrhizal effects on growth and P-uptake of cassava (Manihot escultenta, Crantz) grown in flowing solution culture is described. Phosphorus concentrations were carefully maintained constant at 0.1, 1, 10 and 100 ?M by daily analyses and adjustment of the nutrient solutions....


Howeler, Reinhardt H.Edwards, D.Asher, CJ[Application of the flowing solution culture techniques to studies involving mycorrhizas]Application of the flowing solution culture techniques to studies involving mycorrhizas

Eight cassava (Manihot esculenta) cultivars were grown with or without mycorrhizal inoculation in flowing solution cultures containing approximately 0.1, 1, 10 or 100 ?M phosphate. Rice (Oryza sativa), maize (Zea mays), cowpea (Vigna unguiculata) and French bean (Phaseolus vulgaris) were included...
