Fungal diseases are a yield-limiting factor for wheat. Their management in organic production systems is one of the prevailing challenges because it must be based mainly on indirect measures through agricultural practices. Variety mixtures these practices, concept that has been demonstrated to improve several factors affecting yield. Recently, become practice enables sustainability agriculture. Our research aim evaluate capacity this control three fungal (foliar and ear) durum This study was conducted over two consecutive years (2019 2020) at locations: certified farm Benslimane region (2019) National School Agriculture Meknes (2020). Four wheat varieties (Isly, Tarek, Karim, Nassira) were used create mixture. The parameters monitored disease severity, grain yield, its components. analysis variance diseases’ severity significant. variety showed resistance all Isly variety, most susceptible Nassira variety. other variable from year other. mixture average values. It allowed reduction leaf rust 47% during first 30% second compared (Nassira). In case HLB (helminthosporiosis blight), reduced by 34% 2020 season. For ear disease, Fusarium head blight (FHB), 68% 2019 49% 2020. also ensured yield stability between trial (1.66 t ha−1 1.54 ha−1).
