Mitigating nutrient stress in faba bean in the Ethiopian Highlands: Improving biomass yield, carbon assimilation, and water‐use efficiency through Rhizobium and phosphorus management
Nutrient deficiency limits faba bean ( Vicia faba L.) biomass yield, carbon (C) assimilation, and intrinsic water‐use efficiency in highland agroecosystems. Carbon isotope composition (δ 1 3 C) is indicative of plant physiological responses. This study investigated the effects of phosphorus (P) fertilizer, Rh...
