摘要：Haricot bean ( Phaseolus vulgaris L.) can be an important source of Fe for human nutrition, particularly in regions in which human Fe deficiencies are known to occur. A study using replicated field and greenhouse experiments was conducted in Ethiopia to evaluate the yield and Fe uptake response of different haricot bean varieties (Nasir, Ibado, Hawassa Dume, and Sari-1) to different levels of foliar-applied iron (Fe) fertilizer (0, 1, 2, and 3% solution). Pot experiment results indicated yield, yield components, and tissue Fe concentrations varied among varieties and across soils. The variety Ibado yielded the highest leaf Fe concentration (290.19 mg kg -1 ) whereas Hawassa Dume had the highest number of pods per plant (7.28) and grain yield (15.85 g per pot). Varieties Sari-1 and Nasir produced the highest number of seeds per pod (4.94) and seed Fe concentration (59.02 mg kg -1 ), respectively. Levels of Fe fertilization did not significantly influence yield and yield components, but significantly increased both leaf and seed Fe concentrations. Application of 3% FeSO 4 .7H 2 O produced the highest concentration of both leaf (339.50 mg kg -1 ) and seed Fe (53.46 mg kg -1 ). Field experiments revealed that haricot bean varieties significantly varied in yield, yield components, and leaf and seed Fe concentration. Highest grain yield (3099.55 kg ha -1 ) was observed with variety Hawassa Dume. Production was significantly influenced by planting season and location. Overall, 3% FeSO 4 .7H 2 O fertilizer application best improved the quality of haricot bean produced.
