Nitrogen and sowing time response of six wheat varieties – Wongarbon 2014

Abstract

Key findings • There was no significant effect of N application on yield due to high background soil N levels but there was a slight increase in protein and screening levels with increased rates of N application. • Nitrogen management strategies need to be matched with starting N levels through the soil profile to maximise return on investment. • Earlier sowing increased yield across all varieties and tended to slightly reduce both protein and screening levels.
