“…Humidity in a greenhouse affects the growth and yield of crops such as tomatoes (Bakker, 1991;Jolliet and Bailey, 1992;Jolliet et al, 1993). Consequently, modern greenhouses use both CO 2 application and humidification by the fogging system (de Gelder et al, 2012;Harel et al, 2014). Yasuba et al (2011) investigated temperature, CO 2 concentration, and vapor deficit in a greenhouse with CO 2 application and fogging, and reported the yield improvement of Japanese tomato cultivars under the environmental conditions.…”

To investigate the mechanism of yield increase by elevated carbon dioxide (CO 2 ) and fogging in Japanese tomato cultivars (Solanum lycopersicum), total above-ground dry matter (TDM), fraction of dry matter distribution to fruit (FDF), and photosynthetic characteristics were measured in 3 Japanese cultivars grown in elevated CO 2 with fogging and ambient CO 2 without fogging. Fresh fruit yield and TDM were improved by the elevated CO 2 and fogging in the 3 Japanese cultivars. Light use efficiency (LUE) was also increased by the elevated CO 2 and fogging. No significant decrease in FDF was observed by the elevated CO 2 and fogging in 2 Japanese cultivars, 'Asabiyori 10' and 'Junkei Aichi Fast'. Thus, the increase in TDM by higher LUE contributed directly to the yield increase in these 2 cultivars. However, FDF in 'Momotaro York' was decreased significantly by the elevated CO 2 and fogging. Thereby, the yield increase by the elevated CO 2 and fogging was diminished in 'Momotaro York' in spite of the increase in TDM. The number of trusses having immature fruit in 'Momotaro York' under elevated CO 2 and fogging was significantly higher than those of the others, although no increase in the number of trusses having immature fruit was observed in the other 2 cultivars. Although vegetative growth characteristics such as leaf area, LAI, and fresh and dry weights of leaves and stem were increased by the elevated CO 2 and fogging, no negative effects such as a change in lightextinction coefficient and a decrease in maximum photosynthetic rate were observed. The elevated CO 2 and fogging increased the number of harvested fruit but decreased weight per fruit, namely, fruit size, in the 3 cultivars.

“…An exception to these results was found with respect to the accumulation of phenolics, which were also significantly increased in the late summer. It was demonstrated that a maximum increase in contents of lycopene (by 30 %), ß-carotene (by 40 %), phenolics (25 %), titratable acids (by 8 %) and soluble solids (by 15 %) greater CO 2 differences can occur when the greenhouse is operated completely closed (De Gelder et al 2012).…”

thetic activities, which predominantly occurred in the greenhouse with the semi-closed operation mode. Furthermore, the new technology can be seen as new horticultural approach to reduce the yield of blossom-end rot fruit by 75.2 %. This quality improvement was caused by higher levels of relative humidity, where this humidity states were also responsible for a reduction in the annual plant transpiration rate by 10 %. Vergleich unterschiedlicher Gewächshaussysteme und deren Auswirkungen auf die Qualität von TomatenZusammenfassung Tomaten wurden in einem semi-geschlossenen Gewächshaus im Vergleich zu einem konventionellen Gewächshaus produziert und die Auswirkungen der vorherrschenden Klimabedingungen in den Gewächs-häusern auf verschiedene Pflanzenparameter untersucht. Im Vergleich zu konventionell kultivierten Tomatenpflanzen waren der Blattflächenindex (um 21 %), die Anzahl der Rispen (um 11 %) und der Ertrag der vermarktungsfähigen Früchte (um 31.9 %) der Tomatenpflanzen, die den mikroklimatischen Bedingungen im semi-geschlossenen Gewächshaus ausgesetzt waren, signifikant erhöht. Darüber hinaus führte die Applikation dieser neuen Technologie in den Sommermonaten zu einer signifikanten Erhöhung der Gehalte von Lykopin (um 30 %), ß-Carotin (um 40 %), phenolischen Verbindungen (um 25 %), titrierbaren Säu-ren (um 8 %) und löslicher Trockensubstanz (um 15 %) in Tomaten. Diese Ergebnisse wurden auf höhere photosynthetische Aktivitäten zurückgeführt, die überwiegend Abstract A semi-closed greenhouse was used for sustainable tomato production and to investigate the effects of the prevailing climate conditions within this greenhouse on different plant parameters of tomatoes. Compared to conventionally cultivated tomato plants, the leaf area index, the number of trusses and the yield of marketable fruit of tomato plants exposed to the microclimatic conditions in the semi-closed greenhouse were significantly increased by 21, 11 and 31.9 %, respectively. Furthermore, the application of this new technology led to a significant increase in contents of lycopene (by 30 %), ß-carotene (by 40 %), phenolic compounds (25 %), titratable acids (by 8 %) and soluble solids (by 15 %) in tomatoes during the summer period. These results were attributed to higher photosyn-

“…Near-surface and deep geothermal-energy are also important alternative sources of energy for greenhouse heating, where the utilization of deep geothermal energy is not so prevalent in Germany (Lund, Freeston, & Boyd, 2005;Sanner, Karytsas, Mendrinos, & Rybach, 2003). Another source of energy is the solar energy, which can be collected in heated closed-greenhouses using cold water from soil layers (De Gelder, Dieleman, Bot, & Marcelis, 2012). After absorbing the excess heat in the greenhouse, the heat energy is stored in the aquifer, which can be reused in winter by means of a heat-pump (Bot, 2001).…”

A semi-closed solar collector greenhouse was tested to evaluate the yield and the energy saving potential compared with a commercial greenhouse. As such, new algorithm for ventilation, carbon dioxide (CO 2 ) enrichment, as well as for cooling and heating purposes initiated by a heat pump, cooling fins under the roof and a low temperature storage tank were developed. This cooling system showed that the collector greenhouse can be kept longer in the closed operation mode than a commercial one resulting in high levels of CO 2 concentrations, relative humidity and temperatures. Based on these conditions, the photosynthesis and associated CO 2 fixations within the plant population were promoted during the experiment, resulting in a yield increase by 32%. These results were realized, although the mean light interception by energy screens and finned tube heat exchangers was increased by 11% compared to the reference greenhouse. The energy use efficiency was improved by 103% when the collector greenhouse was considered as energy production facility. In this context, the energy saving per kilogram produced tomatoes in the collector greenhouse is equivalent to the combustion of high amounts of different fossil fuels, where the reduced CO 2 emissions ranged between 2.32 kg and 4.18 kg CO 2 per kg produced tomatoes. The generated total heat was composed of approximately one-third of the latent heat and over two-thirds of the sensible heat, where a maximum collector efficiency factor of 0.7 was achieved.
