The installation and operation costs of drip irrigation systems can be reduced if the systems are designed using a lower uniformity. However, it remains unclear whether a lower system uniformity will result in a decreased crop yield and product quality in arid regions. Field experiments were...

Chinese cabbage (Brassica rapa subsp. pekinensis) production experiments with different system uniformities and field scales controlled by driplines were conducted in a solar heated greenhouse in 2009 and 2010. Three Christiansen uniformity coefficients (CU=62, 81 and 96%) and two nitrogen...

Drip irrigation has been recognized as an efficient irrigation method to improve water and nitrogen use efficiency. However, less-than-optimum management of drip system may cause deep percolation and nitrate leaching. The effects of drip system uniformity and precipitation on deep percolation...
