More detailed information on the performance of irrigation wheat cultivars, including data on the one year performance as well as the long-term data for all the production regions and different planting times, are available in the Production Guidelines published by the ARC‑Small Grain Institute. These guidelines are being distributed to all small grain producers. Contact the ARC- Small Grain Institute at 058 307 3400. Figure 5.
