The lowest-cost option amounts to measuring the illuminance, for which instruments are readily available; more advanced techniques address measurements of radiation and photon fluxes. For the evaluation of photosynthesis under various light sources, the most informative quantity is the flux of photosynthetic photons in the 400―700 nm range of wavelengths (Tibbitts et al., 1983). To comprehensively evaluate the light environment including photomorphogenesis, spectroscopic measurements and analysis are becoming indispensable. Many spectrometers have been introduced into plant research laboratories, leading to some significant advances (Kendrick and Kronenberg, 1986). However, because spectrometers are much more expensive than illuminance meters, this approach is not practical for use in small-scale fields, such as the ones that are cultivated by many farmers in Japan. Consequently, these relatively expensive devices remain unpopular. The development of the micro electro mechanical systems (MEMS) technology has contributed to miniaturization and cost reduction of sensors (Kaajakari, 2009). Some micro-spectrometer MEMS devices that combine reflective concave brazed gratings and complementary metaloxide-semiconductor (CMOS) linear image sensors have been commercialized (Hamamatsu Photonics, 2017). To fabricate a measuring instrument that uses the MEMS technology, a computer system for controlling and a case for housing are required. Up to date, it has been difficult to solve these problems in research laboratories, and the existing prototypes have been bulky and costly. Recently, digital fabrication technology has been proposed for overcoming these technical problems in a small lot production (Walter-Herrmann and Büching, 2014). Based on the increasing use of open source hardware (computers) and three-dimensional (3D) printers, a framework for developing and manufacturing equipment for digital gadgets, called FabLab, was established (Pearce, 2012). Owing to this technology, fabrication of prototypes has become much less expensive. A low-cost spectrometer, featuring an MEMS device and open source hardware, was designed and manufactured using a 3D printer. Four manufactured spectrometers were installed inside and outside of a tomato canopy in an experimental greenhouse, and were tested to determine their usability for continuous measurements and spectroscopic","PeriodicalId":85505,"journal":{"name":"Seibutsu kankyo chosetsu.

In order to feed the world, protect the environment, improve health, and achieve economic growth, a new form of agricultural cultivation is required; indoor vertical farming, namely a plant factory system with artificial lighting, is expected to provide efficient production of food crops (Kozai et al., 2015). However, production in plant factories incurs several costs. Kozai (2007) and Ohyama (2015) previously studied the production costs; as the size of the plant factory increases, fixed costs increase, for example, large-scale air conditioning systems, automatic control systems for nutrient solutions (Son and Takakura, 1987; Ko et al., 2013) and high-throughput seedling diagnosis system (Moriyuki and Fukuda, 2016). Moreover, individual differences in plant growth (growth distribution) are also directly linked to profits. Therefore, a profit model is required to consider fixed costs, running costs, and growth distribution information in plant factories. In the profit model for plant factory, we should focus on shipping type and growth distribution at each growth stage (nursing stage and cultivating stage). The shipping type usually depends on a shipping threshold based on fresh weight of harvested plant. Plants over this threshold are able to be sold at a standard (good) price, one by one (yen plant ). On the other hand, plants less than this threshold are sold at a lower price, by unit of fresh weight (yen g ). Therefore, profit depends on the distribution of plant size at harvest, particularly on the ratio of standard plants that are over the shipping threshold. Moreover, because profit often fluctuates with growth fluctuations, the profit model also requires detailed information of growth dynamics (distribution of plant size and its time variation). However, growth dynamics in plant factory and their influence on profit as a function of shipping threshold have not been widely studied. Variables in the profit model included number of cultivation days, shipping threshold, cost-related parameters such as fixed costs and running costs, and growth-related parameters. Furthermore, parameters in the profit model depend on the plant factory. Therefore, total optimization for all parameters requires time and expense (Shuku and Nishimura, 2015); thus, it is also important to analyze the sensitivity of each parameter for profit and to identify the priority of these parameters. In this study, we investigated the growth dynamics of lettuce populations cultivated in a large scale commercial plant factory and established a profit model with various shipping types. In addition, the sensitivity analysis of this profit model was performed for each parameter, and significant parameters for profit were clarified.","PeriodicalId":85505,"journal":{"name":"Seibutsu kankyo chosetsu.

Optimal postharvest ripening depends on many factors, but during shipping to distant high-value markets, ripening generally should be minimized. Monitoring the physiological activity presents possibilities for real-time response and the integration of smart technologies. However, systems are still needed which are portable, economical, and accurate. Optical sensors are low-cost but lack good accuracy, while electrochemical sensors are highly accurate but expensive. Economic nanoparticle sensors are being developed for potential applications in fruit quality monitoring, but they can be complex. This work explores possibilities for development of a monitoring system for climacteric fruits such as mango and presents results on testing of commercially available systems and development of sensors that will fit the criteria.","PeriodicalId":85505,"journal":{"name":"Seibutsu kankyo chosetsu.
