Abstract
This study was implemented to evaluate the performance of biofortified bean under different integrated soil fertility management (ISFM) options and agro-ecological conditions in Democratic Republic of Congo (DRC). A Split-plot design with eight genotypes as main factors and four ISFM options as secondary factors was carried out in eight production zones distributed across South-Kivu, North-Kivu, and Katanga provinces. The application of lime + manure + NPK increased the bean yield by 173% in Lohutu. Compared to local variety in Lohutu, the CODMLB001 variety under the same option increased the yield by 252%. The same ISFM option allowed best response in terms of micronutrient content of bean in Rutshuru, inducing up to 80.3 mg.kg-1 Fe, representing increase 41%. For Zn, the best response was obtained with lime + NPK applied in Kipopo that induced up to 32.2 mg.kg-1 Zn. Lime + manure + NPK fertilizer option reduced root rot severity by 17.8% compared to the control. This study confirmed the potential of increasing bean productivity, micronutrient and reducing the severity of major diseases through application of soil fertility management options, which will vary with the bean genotype and the environment under which bean is cultivated. Key words: Integrated soil fertility management, bean yield, micronutrient content, disease control, Phaseolus vulgaris L.  
Highlights
Common bean (Phaseolus vulgaris L.) is one of the most important food legumes for direct consumption in the world (HarvestPlus Iron-bean, 2009; FAO, 1999; Juhi et al, 2010)
The potential of increasing bean productivity, micronutrient content and reducing of the disease severities is possible through promotion of appropriate soil fertility management options and genotype of the biofortified bean according to the environment under cultivation
Use of high-performing bean genotypes under integrated soil fertility management, like the combination of lime, manure and mineral fertilizers (NPK 10-20-10); in almost all agro-ecological zones, has significantly increased yield, micronutrient content and reduced the severity of major diseases and pests that are with low soil fertility and rainfall disturbances, factors limiting the production of beans in the Democratic Republic of Congo (DRC)
Summary
Common bean (Phaseolus vulgaris L.) is one of the most important food legumes for direct consumption in the world (HarvestPlus Iron-bean, 2009; FAO, 1999; Juhi et al, 2010). Because of their high protein, mineral and fiber content, beans are consumed instead of meat in developing countries (Wortmann et al, 1998). According to Welch and Graham (2004), biofortified crops are likely to have a positive indirect impact on agriculture, with a higher mineral content that provides better protection against pests, diseases and environmental stresses besides increasing yields Dissemination of such seeds to poor rural households is one of the best ways to improve their diet and to combat malnutrition
