To determine the nitrogen responses of new barley varieties.
There wass no significant difference in the way varieties respond to various amounts of nitrogen (N). Results indicate that for all varieties, as N increases, yield increases incrementally. the most profitable N rate for Commander, Buloke and Hindmarsh is 80kg N/ha, whilst Gairdner was still more profitable at 120kg N/ha
