Vertical indoor farming (VIF) is recognized as a resilient production method, however, its environmental performance is significantly limited by electricity demand. To provide experimentally validated evidence for fruiting crops, this study combines cultivation data from chili pepper grown at two photosynthetic photon flux densities (250 and 500 μmol m-2 s-1) in a VIF container with a life cycle assessment of three distinct energy supply scenarios. Doubling the light intensity raised annual dry yield by 57% to 3.1 kgDW m-2 a-1 but decreased light-use efficiency by 27%. System-level energy and water use remained similar across treatments at 922 kWh kgDW-1 and 14 L kgDW-1 respectively. With a fossil-based electricity mix, climate impact reached 74 kg CO2-eq kgFW-1, primarily due to lighting and cooling. Adjusting the light intensity or expanding the cultivation area within the VIF container only marginally reduced this impact. In contrast, utilizing renewable electricity with industrial waste-heat cooling reduced the impact to 3.9 kg CO2-eq kgFW-1, comparable to upper range values reported for tomato high-tech greenhouse systems. These findings demonstrate that the environmental performance of fruiting-crop vertical farms is mainly determined by the energy source rather than cultivation intensity or layout, underscoring the importance of integrating energy systems to improve sustainability outcomes.
Capsaicinoids, biosynthesized in pepper fruits (Capsicum annuum), are valuable compounds with diverse industrial applications. Their consistent production is essential but influenced by environmental factors such as light intensity and spectrum. Vertical indoor farming (VIF) systems offer precise environmental control over growing conditions, especially light, yet high energy costs often necessitate reduced light intensities. While peppers are light-demanding plants, their integration into VIF systems requires a balance between energy input and crop performance. To evaluate the feasibility of cultivating Capsicum annuum under energy-saving conditions, we investigated the effects of two reduced light intensities (250 / 500 µmol m⁻² s⁻¹) on fruit yield and quality across two chili pepper cultivars and one bell pepper in VIF conditions. Additionally, we assessed whether supplemental UV-A exposure at 500 µmol m⁻² s⁻¹ could enhance capsaicinoid accumulation.Capsaicinoid content per unit dry fruit mass was not significantly affected by light intensity or UV-A as main effects. However, a significant interaction between cultivar and treatment indicated genotype-specific responses. Medium light intensity (500 µmol m⁻² s⁻¹) significantly increased net photosynthesis and fruit number, resulting in 33–57 % higher dry fruit yield (12.5–29.2 gDW plant⁻¹) compared to the lower intensity (250 µmol m⁻² s⁻¹), and led to a corresponding increase in capsaicinoid yield per area, depending on cultivar. Light levels of 500 µmol m⁻² s⁻¹ are necessary to maximize yield and capsaicinoid output in VIF, while cultivar selection plays a critical role in determining compound accumulation.
Vertical Indoor Farming (VIF) offers a potential for high-quality strawberry production, but resource efficiency data still need to be provided. Three strawberry cultivars with different fruiting characteristics, one Ever-bearing cultivar and two June-bearing (high-yielding and an old, traditional) cultivars, and two light treatments were investigated: artificial white LED light with an additional 2% UVA (365 nm) and white LED light alone. The Ever-bearing cultivar demonstrated significantly higher efficiencies for surface use efficiency (SUE) of 15.2 kg fresh weight m-2 a-1, water use efficiency (WUE) of 291 g fresh weight l-1, and energy use efficiency (EUE) of 10.6 g fresh weight kWh-1, due to a high harvest index of up to0.8 and a low proportion of non-marketable fruit. However, the total energy demand of a container VIF is high, with 4.4-6.4 kWh m-2 d-1. Additional UVA radiation did not significantly alter the Ever-bearing cultivar’s performance. At the same time, multiple harvests and a low proportion of non-marketable fruits led to a higher cumulative yield and increased efficiency, making it a promising choice for strawberry cultivation in VIF.
The value chain of flowering potted plants (FPP) is associated with environmental, social and economic sus-tainability challenges. Indicator-based assessment methods can provide insights into sustainability performanceof agricultural value chains. The FPP value chain is not comparable to other agricultural systems and thereforecannot be assessed with existing indicator-based tools. In this study, a framework was developed for sustain-ability assessment of the FPP value chain, from breeding to distribution. The development of the frameworkinvolved defining sustainability themes and subthemes based on the characterization of the value chain and theinvestigation of social, environmental and economic sustainability challenges. The generic sustainabilityassessment tools, Sustainability Assessment of Food and Agriculture Systems (SAFA) and Response-InducingSustainability Evaluation (RISE), provided the foundation for indicator selection and development. The cur-rent study emphasized the need for a system-specific view, especially in unique systems such as the FPP valuechain, because generic assessment tools, such as SAFA and RISE, do not cover all sustainability subthemes. Mostof the indicators missing from generic assessment tools were environmental indicators. Environmental assess-ment is closely related to value chain stages and product-specific processes, therefore indicators were allocatedaccording to the value chain stages, breeding, production and distribution. Social sustainability themes areinfluenced by national and regional socio-economic conditions, such as government provision of healthcare and asocial safety net. Therefore, indicators are allocated based on geographical regions and stakeholder groups. Theeconomic subthemes are determined by industry structure and sector-specific conditions. The ornamental sectoris characterized by low margins and high uncertainty, related to profitability and vulnerability. Despite the initialevaluation performed in the current study, in the next step, industry actors need to determine the feasibility ofthe indicators. The implementation of the framework developed in the current study will provide further insightsinto the value chain, which will guide actors in taking actions for performance improvement and provideguidance for policy-makers in setting sustainability targets.
Plant production in indoor farming systems offers significant advantages compared to open field orgreenhouse production systems. Especially in terms of quality and the ability for automation the system is superior to the conventional production systems. Concerning resource consumption indoor farming has considerable advantages in regard to water consumption and the use of pesticides.The main disadvantage is the high consumption of electrical energy. Taking advantage of the specific benefits or eliminating the disadvantages, for example by using renewable energies, different potentials and fields of application for indoorfarming arise.The paper outlines the potentials and future fields of application of indoor farming considering the specific differences to conventional production systems related to resource consumption, quality and automation.
Climate change and increasing global urbanization accelerate the expansion of protected cultivation systems. However, certain dependences to external weather conditions remain even in modern greenhouses. Indoor vertical farming, on the other hand, pursues complete inde-pendence from external weather conditions with the aim for highly accurate control of all crop parameters. Particularly with regard to the advancing climate change and the need for sustainable resource consumption, there are clear advantages due to the year-round and independent cultivation of plants and raw materials under optimal conditions. The complexity in the optimal networking of the plant-technology systems offers intensive development opportunities for dig-itization and interdisciplinary collaboration.
In the past few years, portable and smartphone-based diagnostic technologies have found their way into the agri-food industry. The aim of this research was to evaluate the perfor-mance of portable near-infrared (NIR) spectrometers, so called food-scanners, with regard to their predictive accuracy of important quality parameters of fruit and vegetables. Food-scan-ner measurements were performed in combination with destructive measurements of the corresponding quality trait (sugar content, dry matter, relative water content) on a wide range of produce from the fruit and vegetable assortment. This study evaluated dry matter content of apple, avocado, blueberry, table grape and tangerine, which yielded cross validation re-sults (r²) of up to 0.95, 0.87, 0.94, 0.92 and 0.92 respectively. Furthermore, the evaluation of food-scanner spectra for the prediction of sugar content of blueberry, kiwi, mango, persim-mon, table grape, tangerine and tomato yielded cross validations (r²) of up to 0.95, 0.84, 0.80, 0.75, 0.95, 0.93, and 0.87. Furthermore, relative water content of ginger obtained a cross val-idation correlation of r² = 0.91. The results show that these traits can be predicted with a high degree of accuracy using non-destructive measurements performed with three commercially available food-scanners SCiOTM, F-750 Produce Quality Meter, and H-100F. Consequently, food-scanners can be used as objective measurement tools along the supply chain of fresh produce to quickly determine fruit quality. In addition, a practical example shows the poten-tial of these instruments for non-destructive quality assessment in incoming goods control at fruit and vegetable wholesalers over a time period of several weeks. Furthermore, possible areas of application of food-scanners along the supply chain of fresh produce are discussed, possibilities for practical applications are presented and time-saving means are highlightedLANDTECHNIK 76(1), 2021, 52–67Food-scanner applications in the fruit and vegetable sectorSimon Goisser, Sabine Wittmann, Heike MempelIn the past few years, portable and smartphone-based diagnostic technologies have found their way into the agri-food industry.

Indoor vertical farming offers great opportunities regarding a sustainable and consistent production of high-quality herbs and raw materials all year round for the perfume, chemical, or food industry. Cultivation takes place in an enclosed structure, operating predominantly independent from external conditions in multi-layer systems equipped with artificial lighting, enabling extremely high resource use efficiencies with a simultaneous increase in yield. On the other hand, field production in terms of plant quality and harvesting times is highly influenced by environmental conditions, making it difficult to maintain homogenous raw material qualities throughout the year. To show how different light qualities affect the overall efficiency and quality of Origanum majorana grown in an indoor farm, the resource consumption, yield, and cultivation time as well as the essential oil quantity was analyzed, and the efficiencies in terms of energy and land use efficiency calculated. The experimental setup clearly demonstrated that the yield regarding fresh as well as dry matter and oil content was comparable to one square meter of open field production. Based on this, the multi-layer system and the noticeable lowered growth period result in a significantly higher area efficiency compared to the open field, leading to a potential increase of annual yields of dried leave weight and oil contents by up to 21 times. It was also shown that a white spectrum (W) showed similar influence on plant growth and yield as a spectrum consisting of blue and red (B/R). Nevertheless, the LED treatment W did show higher light use efficiencies as well as a better working conditions inside the cultivation chamber. By an integration of indoor vertical farming into existing industrial processes, new and innovative opportunities for a flexible and low-risk supply chain seem feasible and according to German food industry meet the interests of existing stakeholders.

The assessment of tomato fruit quality depends on a variety of extrinsic and intrinsic quality parameters such as color, firmness and sugar content. Conventional measurement methods of these quality parameters are time consuming, require various measurement devices, and in case of intrinsic quality, involve destructive measurements. Latest research focused on the non-destructive determination of these parameters by using spectroscopic measurements. The goal of this study was to evaluate the capability of three commercial-ly available portable and miniaturized VIS/NIR spectrometers, socalled food-scanners, in predicting various tomato quality attributes in a non-destructive way. Additionally, this study evaluated the software provided by manufacturers for building of prediction models by comparing the results derived from those software tools to state-of-the-art software for multivariate analysis. Evaluation of food-scanner spectra resulted in prediction models of high accuracy (r² > 0.90) for tomato fruit firmness, dry matter, total soluble solids and color values L*, a* and h°. Prediction models computed with manufacturer’s software showed similar accuracy to those derived from state-of-the-art evaluation software. Results of this study illustrate the great potential of commercial food-scanners for non-destructive quality measurement. Further important features of food-scanners with respect to the application along the fresh produce supply chain are addressed.

Content of teaching is often highly specialized for each course of studies, and students rarely have the possibility to learn more about related content which is outside of the subject area. Nevertheless, e.g. in indoor vertical farming, not only horticultural expertise is required to face the need for automated processes throughout the whole supply chain. We present here a unique approach to bring students from different courses of study together to develop digital solutions for these challenges in an agile environment. Agile in this context means letting students from different disciplines work together in a self-organized manner without hierarchies and based on the project management framework Scrum. In a first attempt, we let students with horticultural and bioinformatics backgrounds develop a digital tool that automates early detection of nitrogen deficiency for sunflowers grown in a greenhouse.

Visible-Near-Infrared Scanners enable a noninvasive prediction of quality properties of fruit and vegetable based on previously created models. A combination of NIR scanners andmachine learning methods can lead to economic improvements and reduction of food waste by strategies like „first expired, first out“ and dynamic pricing. In order to identify parameterscapable of showing dynamic postharvest development, three horticultural products with different postharvest behavior (e. g. strawberry, table grape and mango) were chosen formorphological and statictical analysis. According to the results, a graduation of spectra in correspondence to the day of measurement was noticeable for strawberry regarding the a-value as well as presumingly mass loss for both mango and table grape. Furthermore, a PLS model for the a-values r2cv = 0.80 was developed for strawberries.
