In sahelian contries like Niger, the market garden is a sustainable response to improve agriculture yet dominated by dry crops. This work is produced to analyze the technical efficacity and to identify socioeconomics and technical factors which explain this techncal efficacity. The approach used is the Stochastic Fronter Analysis and Cobb-Douglass is applicated as function of production. In order to identify the determiants of this efficacity, the Fractionnal Regression Model is used. It results that the efficacity scores averages are 44,51% for tomato, 51,81% for piment and 64,09% for cabbage. Between the farmer who is near the fronter and the farmer who is fare the fronter, we have a high contrast. The results show that being alphabete, access to vulgarisation, the farmer’s object and being near of exploitation improve the technical efficacity. However, selling in the exploitation, being in farmers’organisation and the contractualization with traders reduce the technical efficacity. This paper purpose to government and their partners to include rainy market gaderning in agricultural policy.
