Agroecological settings and seed recycling account only partially for potato seed degeneration in Ecuador by Navarrete, I., López, V., Andrade-Piedra, J.L., Almekinders, Conny J.M., Kromann, P., Struik, P.C.

“…This suggests that more research about seed degeneration needs to also take place under farmers’ conditions to fully understand the complex of potato performance factors. We expect that such research will support the design of improved seed interventions, while simultaneously it may generate discussion about when potato seed degeneration plays an important role in productivity.…”

Estimating acid soil effects on selected cereal crop productivities in Ethiopia: Comparing economic cost-effectiveness of lime and fertilizer applications by Warner, James, Mann, Michael L., Chamberlin, Jordan, Tizale, Chilot Y.

“…The application of agricultural lime is the standard corrective, although the large application requirements, lack of farmer awareness, and weak or non-existent lime supply chains make this a complex problem to address at scale. To date, no large-scale farmer trials of lime application have been undertaken in Ethiopia. …”
