Rwanda's northern and western provinces are experiencing a shortage of seed potatoes, a problem that could lead to nutritional insecurity and price increases. The shortage is due to a disease called 'Sembeshyi' that affected mother plants, making it difficult to select good seed potatoes. The issue is further complicated by the use of unprofessional propagators. According to the Rwanda Agricultural and Animal Resources Development Board (RAB), the average potato yield is lower than the potential, with potato growers harvesting an average of 16 tons / ha compared to the expected 30 tons. Rwanda grows 916,000 tons of potatoes annually, making it the third most popular crop in the country.
