Ecosystem water use efficiency (WUE) can be defined as the ratio of net CO2 exchange to evapotranspiration, which implicates the interactions between carbon sequestration and water consumption. Previous studies mainly focused on ecosystem WUE for forests, grasslands and farmlands, but paid...

Partial root-zone irrigation (PRI) is an irrigation technique to save irrigation water without much yield reduction. We investigated if the benefits of PRI on physiology, fresh fruit yield, fruit quality and water use efficiency (WUE) of pot-grown tomato could be modified by different calcium...
