Wheat production falls behind that of other staple crops like corn and rice despite being the world's most extensively cultivated crop in terms of land use. Unlike other staple crops, wheat has the innate ability, as a long-day plant, to absorb and utilize light for 24 hours which can shorten its growth cycle and multiply its annual production. However, while various studies have been conducted on the growth response of wheat to light, there are few studies on the energy demand of shortening the growth cycle for wheat using light. The purpose of this study is to assess the energy demand for maximizing the potential increase of wheat productivity by supplementing LED light to minimize its growth cycle. This experiment is designed to grow four wheat cultivars subjected to only natural light and additional LED lights for 24 hours. The growing period can be reduced from the conventional 250 days to around 90 days, in which wheat is harvested up to 4 times a year. In this study, we quantify the additional electricity consumption to reduce the growing period for multiple annual harvests of wheat and assess the economic feasibility and environmental implications of a smart wheat production system. This study can address both the potential of a smart wheat production system and the critical factors for high wheat productivity.
