AB Cadmium (Cd) is one of the heavy metals commonly present in soils that is toxic for living organisms and carcinogenic in humans. The uptake of Cd by a crop depends on various factors such as soil properties, plant-soil interaction, fertilizer management, and previous crop. The aim of the present study was to evaluate the residual effect of three Cd rates applied in three preceding crops (durum wheat [Triticum turgidum L. var durum], white lupine [Lupinus albus L.], and narrow-leafed lupine [Lupineus angustifolius L.]) on total dry matter, grain yield, and Cd concentration and uptake in three durum wheat cultivars in four environments. The residual effect of a cadmium chloride (CdCl2) dose applied in the preceding crop to durum wheat was affected by location and previous crop, with the greatest effect in La Serena with narrow-leafed lupines as the preceding crop. Finally, in soils where a critical level of Cd is present, narrow-leafed lupines should not be used as a previous crop to durum wheat.
