- Abstract
- This thesis investigates agronomic interventions for faba bean biofortification to alleviate micronutrient deficiencies in Ethiopia. The study consisted of consecutive field-based approaches and laboratory experiments. Initially, it assessed the levels of Fe, Zn, and Se in faba beans grown under farmers' practices, revealing wide variations influenced by spatial factors. Subsequently, pot and field experiments were conducted to evaluate the efficacy of plant biostimulant applications in enhancing faba bean growth and seed micronutrient contents, with no significant improvement observed. The study then focused on a field experiment dedicated to increasing seed Se content using seaweed-based biostimulants and Se fertilizers, resulting in significant improvements. Additionally, the research measured phytic acid and phenolic content in raw seeds, serving as anti-nutritional factors. Finally, the bioaccessibility of Fe, Zn, and Se in cooked beans was evaluated using an in vitro test. Despite raw seeds covering a substantial portion of the recommended dietary allowance (RDA), the study emphasized that cooked beans may not provide adequate nutrient intake, highlighting the necessity for strategies to enhance nutrient bioaccessibility
