Current Demonstration Projects

Since its inception in 1993, SEPWA has undertaken a diverse and extensive range of trials and projects to help Esperance Port Zone growers produce premium quality wheat, barley, canola and legumes. SEPWA has a range of trial data available back to 2011. To access records from earlier years, please contact us.

Legumes – 2 SITEs

Site Location: Grass Patch, Wittenoom Hills
