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...

Bacterial wilt, caused by Ralstonia solanacearum, is emerging as a major threat to potato production in Ethiopia, reaching epidemic proportions in the Chencha district recently, with a prevalence of 97% of potato fields in 2015. The recent disease outbreak in the district coincided with a signifi...

Potato yields in sub-Saharan Africa remain very low compared with those of developed countries. Yet potato is major food staple and source of income to the predominantly smallholder growing households in the tropical highlands of this region. A major cause of the low potato yields is the use of p...

This paper used the propensity score method to assess the effect of using certified seed potato (CSP) on yield, input use, and food security among smallholder farmers. It focused on potato growers in central highlands of Kenya. The study found positive effect using certified seed on both yield an...
