National Taiwan University

 

Plant factories (PF) have been expected to contribute to solving global issues related to population, resource and environment by achieving the highest possible yields and quality with the minimum consumption of resources and minimum emission of environmental pollutants in limited land areas with non-fertile soil by fully exploiting the latest advances in science, engineering and technology. This course covers all basic and application aspects of the PF, including design and components of the PF, factors affecting plant growth, physiology of leafy and fruit vegetables, crop cultural practices, engineering economic, literature reviews of light quality and value-added crops related papers, business models and quantitative evaluation of total performance of PF.
