Résumé

This study analyses the dynamics of market garden cropping systems and the impact of pesticideand fertiliser use. The methodology combines secondary and primary data. Descriptive statistics, therelative importance index, the impact frequency index and ordered logistic regression were used toprocess the data. The study showed that market gardeners have several market gardens croppingsystems, including eight cropping systems before the development of the lowland and thirteen croppingsystems today. The dynamics of the cropping systems are accompanied by a high frequency of pesticideand fertiliser use. The study also shows that the dynamics of pesticide and fertiliser use are influencedby the type of market targeted by the growers, the type of vegetables grown, the level of the water table,climatic variables, the level of education, the size of the plots and the level of equipment used by thegrowers.
