Dans la zone soudano-sahelienne du Burkina Faso, les associations mixtes cereales-legumineuses dominent les surfaces cultivees annuellement. Cependant, les rendements sont faibles et ne couvrent souvent pas les besoins alimentaires des exploitations qui les pratiquent. Afin d’ameliorer la productivite de ces associations, il est necessaire de comprendre la logique socio-economique de leurs mises en oeuvre. Dans cette optique, 60 exploitations agricoles familiales (EA) ont ete enquetees dans la region Nord du Burkina. Des analyses en correspondances multiples (ACM) font ressortir 4 types de systemes de culture caracterises d’une part par le niveau d’apport de matiere organique et la frequence de desherbage et d’autre part, par la presence de structures perennes de conservation des eaux et des sols. La fertilisation organique et le desherbage frequent sont associes aux EA les mieux pourvues en main d’oeuvre familiale, en petits ruminants et surfaces agricoles. L’âge de l’exploitant agricole et le nombre d’epouses sont de bons indicateurs des moyens economiques de l’EA. La plupart des recettes monetaires annuelles par EA varient dans la gamme tres large de 25 a 300 KFCFA. Ces aspects doivent etre pris en compte en vue de raisonner des propositions techniques adaptees a la diversite des EA de cette region. © 2016 International Formulae Group. All rights reserved.

However, yields are low and often do not cover the food needs of farms that practise them. In order to improve the productivity of these intercropping systems, it is necessary to understand the socio-economic logic of their implementation. To this purpose, sixty family farms were surveyed in the northern region of Burkina Faso. Multiple correspondences analysis (MCA) showed four types of cropping systems characterized on one hand by the level of organic matter intake and weeding frequency and on the other hand, by the presence of permanent structures for water and soil conservation. Organic matter fertilization and frequent weeding are associated with farms with high family labor, livestock (especially small ruminants) and high cultivated area, while 70% of farmers have an off-farm activity. The age of household head and the number of their wives are good indicators of farmers’ income. Most of farmers’ monetary recipes vary widely from 25 to 300 KFCFA. These aspects must be taken into consideration for reasoning suitable technical recommendations for the farmer’s in this region. © 2016 International Formulae Group. All rights reserved.
