Abstract

A plot experiment was conducted to determine a critical phalaris basal frequency for pasture production. Small plots (0.84m2) in an existing phalaris pasture were modified to a range of basal frequencies (40-50%, 30-39%, 20-29%, and 10-19%). Pasture dry matter and composition was assessed during the growing season. Phalaris production was reduced when basal frequency was below 20% but growth of annual grasses and subterranean clover resulted in no differences for total seasonal production. The addition of nitrogen increased total pasture production by 37% but reduced clover production by 45%. It is suggested that if basal frequency of phalaris is below 20% then management strategies need to be implemented to increase basal frequency or re-sowing the pasture should be considered.

OtherThe 18th Australian Agronomy Conference will be held at the Mercure Ballarat Hotel and Convention Centre, Victoria from 24-28 September 2017. The Australian Agronomy Conference is the meeting place for Agronomists; it supports research and the community of Agronomists by connecting Agronomy communities across Australia to each other.

The theme for the 2017 conference is “Doing more with less”. A central plank of Australia’s productive output is agriculture, worth over AUD$13.6 billion exported annually. Agronomy is key to ensuring that farmland is productive across Australia’s diverse landscapes. Innovation in machinery and precision technologies, plant species and varieties, soil and plant management may allow the agronomist of today to successfully help agricultural producers thrive. These innovations are timely as the world deals with increasingly variable climates, environmental degradation, and a more developed global community that requires more diverse products from agriculture.
