TI - Subsurface drip irrigation of tomatoes: Drip system design, management promote seed emergence JF - California Agriculture JO - Calif Agr Y1 - 1991/11/01 VL - 45 IS - 6 SP - 21 EP - 23 PB - University of California Agriculture and Nature Resources SN - 0008-0845 UR - http://www.ucanr.edu/sites/calagjournal/archive/?article=ca.v045n06p21 AB - Subsurface drip irrigation has a number of potential advantages over conventional surface irrigation; it curtails weed growth and reduces water loss due to high irrigation uniformity. Depending on a system's design and management, however, it may not always provide adequate soil moisture to germinate the crop seed. This study demonstrates that acceptable levels of seed emergence can be obtained in processing tomatoes using subsurface drip irrigation in clay-loam soil.
