Effect of plant population on yield and oil content of four canola varieties at Trangie and Nyngan 2013

Abstract

Key findings • Increasing plant population up to 20 plants/m2 (established) showed significant grain yield response; but there was no significant effect on yield when plant population was increased further. • Increasing plant population up to 80 plants/m2 showed an overall effect of increasing oil content; however the differences between incremental increases in plant population were not significant. • Based on the response to plant population trials at Nyngan and Trangie in 2012 and 2013, canola growers should aim to establish 20–25 plants/m2 in central-western NSW.
