Senegal imports a large volume of potatoes, i.e. 23,452 tonnes in 2022. These imports have a negative impact on the country’s balance of trade, and reflect its low production capacity for a commodity that is in high demand on the market. Based on the premise that controlling horticultural production helps to reduce food insecurity, the aim of this research is to analyse the potato production, conservation and marketing system in the communes of Notto and Kayar. To achieve this, surveys were carried out with a sample of 150 producers in the two communes. After analysing the data, the results show that in both communes the majority of growers are men, with an essentially temporary workforce made up mostly of women. Annual potato production for most growers is less than 100 tonnes. Also, the quantity of potatoes marketed is less than 50 tonnes/year for most growers. Most customers are «bana-banas», with 97.3% and 93.2% of growers in Kayar and Notto respectively. Growers face a number of constraints, including a lack of training for some growers, problems of access to water, inputs and credit, price fluctuations and a lack of modern storage facilities.
