In this study investigated the nutritive value of Sulla harvested from two calcareous soil sites containing different concentrations of CaCO3, i.e. Kariat Benaouda (10.7%) and Mosmoda (26.0%) located in the northwest of Morocco. Small differences emerged among samples as a result of the sampling site's effect regarding the crude protein and fiber content. However, a significant variation was observed concerning the mineral composition, particularly for iron (Fe) content. Comparatively, Sulla at the Mosmoda site had a higher Fe concentration (875 mg/kg Dray Matter (DM) at the vegetative stage and 194 mg/kg DM at the flowering stage) than at Kariat Benaouda (139 and 15.1 mg/kg DM, respectively). The results of measured secondary metabolites show a high concentration of total phenolics and oxalate content during the flowering stage at the Mosmoda site (4.88 %DM and 27.87 mg/100g, respectively) as compared with the Kariat Benaouda site (3.37 %DM and 16.07 mg/100g). Overall, the plant could maintain a very high value of organic matter digestibility, at the vegetative stage at both harvesting sites (71.11%OM at the Mosmoda site and 84.16%OM at Kariat Benaouda). These findings indicate the efficiency of Sulla for animal nutrition, to improve calcareous soil pastures indigenous to the Mediterranean area.
