Cool season vegetable crops may also benefit from low tunnels (LTs) by enhancing vegetative growth and development.This study compared investigated microenvironmental conditions, growth and production, and water requirements and use efficiency in brussels sprouts grown under LTs and open field. Low tunnels increased minimum soil temperature in all trials. By contrast, LTs reduced evapotranspiration in spite of increased temperatures. Therefore, water needs and irrigation decreased. Furthermore, vegetative growth, yield and water-use efficiency increased. Consequently, LTs may be a useful management tool in sustainable production systems in addition to their traditional role for season extension.
