Regional specific agronomy has been identified as a need by growers in RCSN Open Local Forums, in particular in using regional specific agronomy demonstrations to assist decision making of growers.

The aim of this project was to use best district practice to examine if newer varieties respond differently to increasing nutritional inputs and whether this can be exploited by growers.

This was done by measuring crop performance with different sowings times and nutrition regimes, representing different decision-making scenario's depending on budget and seasonal rainfall.

This information should then assist grower’s decisions with variety specific agronomic management.
