Soil erosion rates are exacerbated in sloping arable lands of Central Kenya due mainly to the high soil disturbance caused by potato hilling. A field study was conducted in runoff plots to quantify the effect of potato hilling on soil loss, soil moisture distribution and soil temperature. Three h...

Purpose – Potato is a major food staple in Africa, but its production is constrained by poor quality of seed. A recent private–public partnership in Tanzania resulted in introduction of new higher yielding varieties. The purpose of this paper is to examine smallholder farmers’ motivations to inve...

Good quality seed is almost universally considered a requirement for high productivity in all potato production systems. Much of the yield gap currently constraining productivity in low-income countries is attributed to the poor quality of seed. Potato seed sector development is thus a major conc...
