Résumé (UniCat)
In Tunisian cereal semi-arid area, qualitative aspects of mechanised itineraries are little considered in technological package transfer. This results in an insufficient cost-effectiveness ratio of agricultural equipment investments and causes a poor valorisation of the technical efficiency potential of machines. From this comes a productivity reduction of the proposed models designed to improve cereal yields. In this study, four types of cereal farms on rainfed system are considered. A conventional mechanised itinerary including operations of soil preparation, seeding, herbicide treatment, fertiliser spreading and harvesting was defined for each type of farm. The mechanised itinerary was performed according to two procedures : (i) a "farmer mode" which corresponds to conventional mechanised practices and (ii) an "assisted mode" for which mechanical parameters of agricultural machines are better considered and all adjustments are optimised. mechanised intervention date for assisted
