Analyse typologique et performance productive de la culture du blé dur irrigué en Tunisie

Abstract : In Tunisia, irrigated durum wheat is grown on an average annual area of 48 700 ha, which represents two-thirds of the irrigated cereal area. It produces an average of 180 000 t, or 20% of national durum wheat production. However, the yields achieved are still below expectations with low productivity, particularly of water resources. In this context, this work aims to draw up an operational diagnosis of the irrigated cereal farms and to highlight the main levers for improving the performance of the durum wheat crop. To this end, field surveys were conducted with a sample of 698 grain farmers. The data collected made it possible to develop a typology of farming systems and to analyze the performance of the durum wheat cultivation activity. Three types of farming systems were identified: A monocultural system based on durum wheat cropping, a diversified cereal-oriented system and a diversified horticulture-oriented system. Performance analysis revealed a clear disparity between two distinct performance levels for each farming system.
