“…It was found that the productivity of wheat, especially its photosynthetic constituent, is a nearly linear function of incident PPF up to 2.5 times the summer sunlight intensity, taken as the integrated (Bugbee et al, 1989) or instantaneous value (Tikhomirov, 1996). A considerable rise in plant productivity with increasing PPF and CO 2 concentration (up to 2000 ppm, which is 5 times CO 2 content in atmospheric air) was observed by Qin et al (2008) for lettuce, by Wheeler et al (1996Wheeler et al ( , 2008aWheeler et al ( , 2008b for wheat, potato, tomato, and soybean, and by Nelson et al (2008) for pinto bean. For example, the pinto bean matured and harvested 20 days earlier than is typical for this variety in the field.…”

“…Its performance depends on light intensity [photosynthetic photon flux, PPF, 400 to 700 nm, which accounts for 32% of the total Sun irradiance (Sager et al, 1992)], temperature, carbon dioxide and oxygen concentrations, and air velocity over the plant canopy, which must be controlled and monitored in the system (Bugbee et al, 1989;Wheeler et al, 1996Wheeler et al, , 2008aWheeler et al, , 2008bAndre et al, 1989Andre et al, , 1999Borodina et al, 2003;Nelson et al, 2003aNelson et al, , 2008Qin et al, 2008;Kitaya 2003;Kitaya et al, 2008;McKeehen et al, 1996;Allen et al, 1999Allen et al, , 2003Berkovich, 2008).…”

The objective of this study was to make growth and yield models of sowthistle (Ixeris dentata Nakai) by using an expolinear functional equation in a closed-type plant production system. The growth and yield of hydroponically-grown sowthistle were investigated under four different planting distances (15 × 10, 15 × 15, 15 × 20, and 15 × 25 cm). Shoot dry weights per plant was the highest at 15 × 25 cm, but was the lowest at 15 × 10 cm. Shoot dry weights per area was the highest at 15 × 15 cm, but was the lowest at 15 × 25 cm. The optimum planting density and planting distance for yield of sowthistle were 44 plants/m 2 and 15 × 15 cm, respectively. Shoot dry weights per plant and per area were showed as an expolinear type functional equation. A linear relationship between shoot dry and fresh weights was observed to be linear regardless of the planting distance. Crop growth rate, relative growth rate and lost time in an expolinear functional equation showed quadratic function form. Radiation use efficiency of sowthistle was 4.3-6.1 g･MJ -1 . The measured and estimated shoot dry weights showed a good agreement using days after transplanting as input data. It is concluded that the expolinear growth model can be a useful tool for quantifying the growth and yield of sowthistle in a closed-type plant production system.

“…Sowthistle (Ixeris dentata Nakai) is a perennial herb with antioxidant activity (Kim et al, 2002;Lee, 2011) that is used to treat adult diseases such as diabetes (Choi et al, 1990;Hong et al, 2010) and cancer (Kim et al, 2002). This bitter, flavorful vegetable represents a good source of β-carotene, and it has been selected as a candidate crop for CELSS (Controlled Ecological Life Support System) (Qin et al, 2008). The aim of the current study was to develop a Planting-density Growth Harvest (PGH) chart in order to easily estimate the growth and productivity of hydroponically grown quinoa and sowthistle in relation to planting density in a closed-type plant production system.…”

When designing a plant production system, it is crucial to perform advanced estimation of growth and productivity in relation to cultivation factors. In this study, we developed Planting-density Growth Harvest (PGH) charts to facilitate the estimation of crop growth and harvest factors such as growth rate, relative growth rate, shoot fresh weight, harvesting time, marketable rate, and marketable yield for quinoa (Chenopodium quinoa Willd.) and sowthistle (Ixeris dentata Nakai). The plants were grown in a nutrient film technique (NFT) system in a closed-type plant factory under fluorescent lamps with three-band radiation under a light intensity of 140 μmol·m -2 ·s -1, with a 12-h/12-h (day/night) photoperiod. We analyzed the growth and yield of quinoa and sowthistle grown in nutrient solution at EC 2.0 dS·m -1 under four planting densities: 15 cm between rows with a within-row distance of 15 × 10 cm (67 plants/m 2 ), 15 × 15 cm (44 plants/m 2 ), 15 × 20 cm (33 plants/m 2 ), and 15 × 25 cm (27 plants/m 2 ). Crop growth rate, relative growth rate, and lost time were closely correlated with planting density. We constructed PGH charts based on the growth data and existing models. Using these charts, growth factors could easily be determined, including growth rate, relative growth rate, and lost time, as well as harvest factors such as shoot fresh weight, marketable yield per area, and harvesting time, based on at least two parameters, for instance, planting density and shoot fresh weight.
