Irrigation Criteria for Drip-irrigated Onions
Long-day onion (Allium cepa L. 'Vision') was subjected to five soil water potential (SWP) treatments (-10, -20, -30, -50, and -70 kPa) using subsurface drip irrigation in 1997 and 1998. Onions were
Plant Population and Nitrogen Fertilization for Subsurface Drip-irrigated Onion
Onion (Allium cepa L.) production in the Treasure Valley of eastern Oregon and southwestern Idaho has been based on furrow irrigation with 318 kg·ha -1 N fertilizer and average yields of 70 Mg·ha -1

Potato Yield and Quality Response to Deficit Irrigation
Four potato (Solanum tuberosum L.) varieties were grown under four season-long sprinkler irrigation treatments in three successive years (1992-94) on silt loam soil in eastern Oregon. The check
Onion Yield and Quality Affected by Soil Water Potential as Irrigation Threshold
Onion (Allium cepa L., 'Great Scott') was grown on silt loam soils and submitted to four irrigation thresholds and maximized by a calculated threshold of -27 kPa due to a substantial increase of decomposition during storage with increasing threshold.
Onion storage decomposition unaffected by late-season irrigation reduction.
Long-day onion (Allium cepa L.) ‘Vision’ was submitted to four soil water potential (SWP) treatments using subsurface drip irrigation in 1997 and 1998. Onions were grown on two double rows spaced 22
