Agrivoltaics represents a key technology for reaching sustainable development goals by reducing the competition between land used for food, for feed, and for electricity. It has been demonstrated that Agrivoltaics can increase land productivity and play a role in the expansion of renewable energy production. This work aimed to study the yield and nutritional characteristics, as well as feeding value for ruminants of Durum wheat biomass grown under agrivoltaic. Two years of controlled experiments revealed that the reduction in light moderately limited wheat yields in the phenological phase of soft dough in standard agrivoltaic trackers (i.e. with a Ground Coverage Ratio (GCR) = 13%), otherwise under extended trackers (i.e. GCR = 41%), the yields was reduced compared to control in whole light. The digestible neutral detergent fiber evaluated after 24 h of in situ rumen incubations increased with shading, resulting in different ratios of acid detergent lignin. More shaded theses also had superior crude and soluble proteins, acid detergent-insoluble protein, acid and neutral detergent fiber than the control. The biomass in the shaded treatments showed a better Ca: P ratio for ruminant nutrition. These characteristics are strategic in forage production, allowing a more flexible harvesting strategy. This additional contribution of the nutritional characteristics of Durum wheat produced on Agrivoltaic Systems could allow a better inclusion of the different types in diets and better management of silage or hay harvesting sites. These results might be helpful in improving biomass production and give valuable information on Durum Wheat under the Agrivoltaic System.

农业光伏是通过减少用于粮食、饲料和电力的土地之间的竞争来实现可持续发展目标的关键技术。事实证明，农业光伏可以提高土地生产力，并在扩大可再生能源生产方面发挥作用。本工作旨在研究农业光伏下种植的硬质小麦生物质的产量和营养特性以及反刍动物的饲用价值。两年的对照实验表明，在标准农业光伏跟踪器（即地面覆盖率（GCR）= 13％）中，光照的降低适度限制了软面团物候阶段的小麦产量，否则在扩展跟踪器（即GCR = 41）下%)，与全光照条件下的对照相比，产量有所降低。原位瘤胃孵育24小时后评估的可消化中性洗涤纤维随着遮光而增加，导致酸性洗涤木质素的比例不同。与对照相比，更多阴影的这些还具有优异的粗蛋白质和可溶性蛋白质、酸性洗涤剂不溶性蛋白质、酸性和中性洗涤剂纤维。遮荫处理中的生物量显示出更好的反刍动物营养钙磷比。这些特征对于饲料生产具有战略意义，可以实现更灵活的收获策略。农业光伏系统生产的硬质小麦的营养特性的这种额外贡献可以更好地将不同类型纳入饮食中，并更好地管理青贮饲料或干草收获地点。这些结果可能有助于提高生物质产量，并为农业光伏系统下的硬粒小麦提供有价值的信息。
