Potato production in Nigeria
Nigeria is one of the largest producers of potatoes in Africa. The potato was introduced to the country in the 19th century by Christian missionaries and is largely cultivated in the central region of the country in Plateau State. History. The Irish potato was first brought into Nigeria in the 19th century by Christian missionaries. During World War II, the colonial government encouraged Nigerian farmers to grow potatoes to feed British troops stationed in West Africa. A handful of European potato varieties, including pinepernel, ackersegen, dekema, and roslin eburu were introduced to Nigeria afterwards to little  success. In the early 1970s, the State Ministry of Agriculture in Benue took in another set of varieties including ajax, mirka, spunta, Nicola, desiree, diamant, dan-Cameroon, alpha, cardinal and Baraka. In 1976, the Potato Research Programme of the National Roots Research Institute was established in Kuru, to look into ways of improving potato production in the country. In 1986, yet another set of varieties was imported into Nigeria: kondor, bertita, delcora, vento, famosa and romano. Production. The potato is a tuber crop which has high nutritional value. It has protein, calcium, and vitamin C. One potato of medium size  contains 50 percent of the daily vitamin C needs of an adult. Its protein content is reported to be very high compared to other tubers and roots. According to a 2013 study, Nigeria ranks seventh among potato-producing countries in Africa and fourth in Sub-Saharan Africa, with an annual production yield of around and an actual planted area of . In spite of that, the average yield in Nigeria of 3.1 tonnes/ha is among the world's lowest. Potato production in Nigeria predominantly occurs in small farms whose farmers still rely on traditional tools such as machetes and hoes  as opposed to tractors. According to a 2012 study, an estimated 300,000 households in Nigeria engage in potato production, which translates to an average planted area of per household each year. The country's main potato-planting region is the Plateau State (Barkin Ladi, Bokkos, and Mangu) which accounts for almost half of the national potato yield. Other potato-producing areas include Kaduna and Benue. Potato production takes place in both the wet season (April till August) and the dry season (September till March). Additionally, a low level of production occurs from October till January in Kano. The potatoes are  then graded by the Potato Research Programme. On average, some of locally farmed potatoes are sold within the country each year while another 100,000 tonnes are unofficially sold across the West African borders. Potato production in Nigeria faces many constraints, including the unavailability of good-quality potato seeds, poor storage methods, insufficient education on farming methods and pest control, inadequate research and development, and inadequate farming equipment. Cuisine. The potato is regarded as the fourth most important root crop in Nigeria, following the cassava, yam, and cocoyam. French fries and potato crisps are widely consumed in Nigeria, with locally produced  potatoes being used to make Monties and The Kings potato crisps. However, the majority of potato-based snacks in the country are still imported.
