This project aims to investigate different nitrogen rates to determine the nitrogen use efficiency of some of the newer varieties in the Burdekin

There has been much anecdotal data to suggest that some of the newer varieties (Q240, Q253 and Q232) have the potential to be much more efficient users of nitrogen. This has been found by growers who have suffered CCS losses when applying high rates of N. To verify this, we need to find what %N reduction can be achieved to maintain yield in varieties that have shown to be more efficient in N utilisation such as Q240, Q253 and Q232. As a result there is the potential to reduce amount of N applied, improve sugar production, reduce costs and improve water quality.
