Rice is a major strategic commodity in Senegal government's options, it accounts for 34% of national cereal consumption; from which 50% of cereals consumed in urban areas and 24% in rural areas. In Senegal, rainfed rice grows under lowland and upland conditions. Recently, the government create incentives to increase upland rice yield as it might have a huge impact on smallholders that depend on rice production and don't have resources to convert to irrigated systems (Projet d'Appui à la Production Durable du riz pluvial (PRIP) maer.gouv.sn)). Upland rainfed rice has also the potential to be integrated into sustainable cropping systems with less environmental impact and better resilience to shocks than lowland rice. In upland rainfed rice, farmers could plant a rice crop in rotation with other crops; therefore, rainfed rice could become a key component for regional food security in West Africa. In Senegal, there is a huge unexploited land particularly for expansion of rainfed upland rice as only 20% of the area potentially cultivated has been exploited (Villar et al, 2019). However, the promotion of upland rice system has not been successful due to several constraints such as inadequate water availability, poor soil, suboptimal crop management and biotic stress (Saito et al 2018) as well as lack of sufficient knowledge of appropriate varieties and good agricultural practices. Recent field surveys showed socio economic constrains that could explain the low deployment of rainfed rice in Senegal (lack of adapted varieties, mechanization and fertilization) but also showed the importance of rainfed rice for food security. In general, rainfed rice is grown on a small plot with an average of 0.4 ha and 0.27 ha for male and woman farmer, respectively (Direction de l'Analyse, de la Prévision et des Statistiques Agricoles, 2020). It is cultivated in a single season during the rainy season, which covers generally 5 months, from June to October. Rainfed rice remains primarily fo
