Developing and Integrating Components for Commercial Greenhouse Production System

Department of Biosystems and Agricultural Engineering
Project Description
Water is a crucial greenhouse input, yet high quality water is in decreasing supply in many parts of the country. This research investigated the relationship between container moisture content, photosynthesis, and plant biomass for woody plants in greenhouse production. An irrigation model which based irrigation delivery on maintaining plants at a percentage of maximum photosynthesis was developed and validated. The results demonstrated that plants can maintain maximal photosynthesis and growth with reduced irrigation cycles.
Impact
Producers may be able to use this information to decrease water use while maximizing growth.
