Pearl Lupin (Lupinus mutabilis), the nutrient-enriched and climate-resistant legume that was first introduced to the Andes have received a new focus due to its ability to reinforce food security and promote sustainable agriculture under the growing climatic loads. Its adaptation to the marginal environment, combined with the effective biological fixation of nitrogen by symbiosis with Brady rhizobium strains, has made it a valuable crop in terms of mitigating the reliance of the external fertilizer and improving the fertility of the soil. This chapter discusses its agronomic potential, phenological plasticity and adaptive interactions in various production systems with a focus on management approaches that can be implemented to reduce climate effects including selection of genotype-specific environment, organic fertility management, and resource-efficient crop production modes, among other strategies. Its promise is supported by evidence of past studies. In a case study, it was reported that grain yield would be about 18.1 g per plant when growing in the Mediterranean, versus 9.2 g per plant when growing in the Andes, and biomass accumulation would be as high as 2 kg per plant when growing in Northern Europe. In addition, multi-elevation experiments of a recent Andean experiment have shown that moderately warm temperatures did not impair yield or biomass and that organic manure performed just as well as synthetic fertilizers. The further realization of the potential of the crop is to advance breeding specifics; increase genotype/environment match; and improve modeling tools. Future research must increase the exploration of the responsive stress characteristics and further reinforce it into climate-resisting agricultural practice.
