ProjectSeed Potato Multiplication to Improve Food Security of The People of Paekam County, Ryanggang Province, Democratic People’s Republic of Korea - TCP/DRK/3701 2021
Also available in:
No results found.Ryanggang Province is one of the least developed regions in the Democratic People’s Republic of Korea While food security remains a major concern throughout the country, it is particularly challenging in the northern uplands of Ryanggang Province because of the low agricultural productivity and increased vulnerability to the adverse impacts of climate change Moreover, the region is facing problems associated with degenerated varieties of potato and fruit trees, degenerated livestock breeds, post harvest losses and a lack of farm equipment and machinery Low agricultural production and productivity affect the supply of food for the public distribution system, and ultimately, the nutritional status of the population According to the 2012 Nutrition Survey, chronic malnutrition ranges from 33 to 39 percent in the northern provinces of the country A major constraint to increasing the productivity of potato crops in Ryanggang Province is the availability of good quality, disease free, high yielding seed varieties When seed potatoes are multiplied conventionally using tubers, new varieties become rapidly degenerated as a result of the progressive accumulation of viruses and pathogens over several cycles of asexual reproduction Additionally, the large scale import of seed potatoes in the late 1990 s to manage the outbreak of late blight introduced new diseases into the Democratic People’s Republic of Korea, including 8 of the 22 known virus and virus like potato diseases The implications of potato disease for food security are substantial, as viral infection has the potential to reduce yields by up to 80 percent. -
Policy briefImproving access to quality seed potatoes 2017
Also available in:
This policy brief addresses the issue of limited farmer access to quality seed of Irish potato varieties in demand in local markets, which is a severe constraint for the potato sector in eastern Africa. It provides evidence in support of urgently needed action and presents options for practical decisions by policy-makers in the subregion. -
DocumentStorage of seed potatoes with the Diffused Light Storage (DLS) principle in Nepal 2011
Also available in:
No results found.Seed constitutes a very important part of potato cultivation as it accounts for almost 50 percent of the total cost and it is the main source of diseases. In addition, unavailability of good quality seed potatoes at the right time is another problem in potato cultivation. Diffused Light Storage (DLS) principle meets the criteria for storing seed potatoes in the hill region at low or no cost, and it can be adapted to any existing on-farm storage. The DLS method is based on the use of natural indirect light and good ventilation or air flow, instead of low temperature, to control excessive sprout growth and associated storage loss. Provided that direct sunlight can be controlled, any kind of existing potato storage facilities can be converted into DLS. It is not necessary to build a new facility and any design used by farmers is good as long as the DLS-principle is adopted. The objective of this practice is to improve the quality of seed tuber through the DLS method.
