“…As a result, the standard procedure had a better environmental performance per kg FOS produced. This study assumed a 30% yield reduction for direct planting, in accordance with Kamp et al [14]. However in other field trials, the recorded yield reduction was considerably smaller.…”

“…The rhizomes are wrapped in perforated bags and stored in lightproof boxes, filled with a mixture of sand and sawdust to absorb humidity. The following year, the rhizomes are sliced into smaller pieces, which are then propagated in the greenhouse, as described in Kamp et al [14]. This procedure is referred to as "standard procedure" in the following text.…”

“…It has been demonstrated that the direct planting of rhizomes can potentially decrease propagation process costs substantially, but that the tuber yield is also considerably lower [14]. According to Kamp et al [14], a yield reduction of up to 30% can occur. For this reason, the influence of direct rhizome planting on the economic and environmental performance of yacon cultivation was assessed in a scenario analysis.…”

“…This pre-cultivation step is quite labour-and energy-intensive. It has been demonstrated that the direct planting of rhizomes can potentially decrease propagation process costs substantially, but that the tuber yield is also considerably lower [14]. According to Kamp et al [14], a yield reduction of up to 30% can occur.…”

As the prevalence of diabetes is predicted to rise globally in the coming decades, the demand for sugar substitutes is expected to increase significantly. In this context, natural sweeteners have been receiving particular attention, as artificial sweeteners have been associated with obesity and cardiovascular disease. One natural sweetener is yacon (Smallanthus sonchifolius) ((Poepp. and Endl.) H. Robinson), which could play a prominent role due to its high fructooligosaccharides yield. Yacon is currently only a minor crop in Europe and there is little information available on the environmental and economic impacts of its various cultivation systems. These are especially affected by nitrogen fertilization levels and genotype selection. Thus, before the crop is introduced on a larger scale, it is expedient to identify the most sustainable cultivation system. The life-cycle assessment (LCA) and life-cycle costing (LCC) analysis of yacon cultivation systems conducted in this study revealed significant differences between yacon genotypes and found that a nitrogen fertilization level of 80 kg N ha−1 significantly decreased production costs and simultaneously led to a comparatively good environmental performance. The results indicated that, for the holistic evaluation of agricultural systems, it is crucial to assess both the economic and environmental performance of new crops.
