Potatoes are a very important crop worldwide among root and tuber crops in terms of production, followed by cassava and sweet potatoes. In Africa,
it comes in 3rd position after cassava and yams and is followed by sweet potatoes and araceae (www.fao.org). In some Third World countries, especially in sub-Saharan Africa, potatoes remain underused, but overall their consumption is increasing in these countries.

In Burundi, while most food production is carried out on family farms using traditional farming methods (D'Haese and Ndimira, 1985), profound agro-economic changes have been made to traditional production methods, leading to increasingly higher
production on small areas. Thus, potato production increased significantly, ranging from 29,306 tonnes in 2005 to 181,209
tonnes in 2014 (https://fr.actualitix.com/).

According to ISABU (2017), potatoes occupy a place of choice for farmers who practice them and are a highly sought-after commodity in urban areas. However, this crop is grown in the high mountains and no potato fields for commercial purposes are cultivated at low altitudes in Burundi (Harahagazwe et al. 2012). Moreover, while some third world countries have other resources besides agriculture, in the case of Burundi, agricultural development including crop diversification is a mandatory path to development.

To do this, the idea was born to introduce potatoes to low-lying areas in order to broaden the range of sources of income of the inhabitants of the plain and to incorporate potatoes into their diet. To measure the level of enthusiasm of farmers in the Imbo plain and assess the importance they give to potato production, a diagnostic survey was carried out.
