THE CORRELATION BETWEEN PRODUCTIVITY AND CROPPING SYSTEMS IN WEST AFRICA : THE CASE OF THE PENSA HYDRO-AGRICULTURAL PERIMETER IN BURKINA FASO

The drought of the 1970 s led to a proliferation of hydro agricultural schemes in West African countries to combat water stress. Burkina Faso is no exception. This study is based on the econometric method, using the cross-sectional hypothesis that there is a correlation between cropping systems and productivity in the Pensa hydro-agricultural perimeter. Its aim is to analyse the correlation between cropping systems in the developed perimeter and productivity in the rural commune of Pensa. Carried out in the rural commune of Pensa, the surveys collected quantitative and qualitative information from 188 people (182 producers and 6 resource persons). The data collected were processed using a logit model. The research results indicate that monoculture and polyculture are the two cropping systems developed in the Pensa hydro-agricultural perimeter. The waiting period for the use of phytosanitary products is 5,25 days for monoculture, compared with a waiting period of 5.35 days for polyculture. The farm accounts show that growing Vigna unguiculata (cowpea) is more profitable in the monoculture system (675,9 F CFA/kg). In the mixed cropping system, the production of Allium cepa L (onion) is more profitable (525 F CFA/kg). The coefficient of determination between cropping systems and productivity was 0,8106.
