Abstract
Aims This study has been carried out to determine the spatial variability of faba bean seed Fe, Zn and Se content across agro-ecological zones in central and southwestern Ethiopia, where it is an important source of protein in the diet. The study assessed whether soil properties, arbuscular mycorrhizal fungi (AMF), faba bean characteristics and genetic diversity and agro-ecological zone as random factor affect seed Fe, Zn and Se content. Methodology Multi-location fields were sampled in three important faba bean growing agro-ecologies during the 2018-2019 cropping season. Results Seed Fe content varied from 45.7-61.9, 41.6-102 and 31.1-77.0 mg kg(-1) in Cheliya, Dedo and Dendi, respectively. Likewise, Zn content ranged from 38.3-56.3, 44.6-73.6 and 21.6-49.9 mg kg(-1). Selenium content varied from 10.1-45.1, 12.1-160 and 16.2-167 mu g kg(-1). Significant differences were observed for Zn and Se content across agro-ecologies. Consumption of 100 g faba beans per day can provide an overall average of 64 and 28% of the recommended daily allowance (RDA) for Fe, 45 and 62% for Zn and only 8% for Se for male and female adults, respectively. Soil properties explained seed Fe, Zn and Se content variation. However, for Zn and Se content the largest share of the difference was explained by agro-ecological mediated environmental variations. As a consequence, differences in dietary intake of micro-nutrients via faba beans are determined by living area. Conclusion Soil properties and especially agro-ecological mediated environmental conditions explained seed Zn and Se content of faba bean and hence potential dietary intake.
