Automation of Subsurface Drip Irrigation for Onion Production
www.cropinfo.net/AnnualReports/1996/ondrip96.htm 2010/08/19 (23107 bytes)
Information on soil water potential was used to automatically control a subsurface-drip irrigation system for onion production. Granular matrix sensors provided the soil water potential data. A datalogger was programmed to maintain soil water ...

Growers Use Less Nitrogen Fertilizer on Drip-Irrigated Onion ...

While 320 lb N/acre is commonly used in furrow-irrigated onion production, drip-irrigated onion is not very responsive to N fertilizer (Shock et al. 2004). The lower response of drip-irrigated onion could be because less irrigation water is applied using drip. ...

Irrigation Frequency, Drip Tape Flow Rate, and Onion Performance
www.cropinfo.net/AnnualReports/2003/onidripfreq03.htm 2010/09/01 (79359 bytes)
Onion production with subsurface drip irrigation has proven at the Malheur Experiment Station to be highly productive on sites that are difficult to irrigate. ... An irrigation frequency of up to eight times a day in small increments is not feasible on a commercial scale. ...

EVALUATION OF AUXIGRO® FOR DRIP-IRRIGATED ONION PRODUCTION 2006
www.cropinfo.net/AnnualReports/2006/AuxigroOnion2006.html 2010/08/07 (82373 bytes)
The objective of this trial was to evaluate the effect of Auxigro on onion yield, grade, and single centeredness when applied through drip irrigation. Methods. The trials were conducted at three sites in the Oregon side of the Treasure Valley: Vale, Oregon Slope, and Ontario. ...

Irrigation Frequency, Drip Tape Flow Rate, and Onion Performance
www.cropinfo.net/AnnualReports/2002/OnionDrip02.htm 2010/08/31 (44528 bytes)
Onion production with subsurface drip irrigation has been tested at the Malheur Experiment Station since 1992. In 1997 and 1998 onions were submitted to five soil water potential treatments using an automated, high frequency irrigation system. ...

Growers Conserve Nitrogen Fertilizer on Drip-Irrigated Onion
www.cropinfo.net/AnnualReports/2002/OnionDripNitrogen02.htm 2010/07/17 (14651 bytes)
From 1992 to 1994 we demonstrated that drip irrigation is an effective irrigation practice compared to furrow and sprinkler irrigation for onion production on Treasure Valley soils that were difficult to irrigate (Feibert et al. 1995). While ...
