This irrigated variety trial is based on the Western side of Emerald and compares Sicot 606B3F, the balance of the field, with five BG3XF varieties. Sicot 619B3XF, Sicot 743B3XF, Sicot 761B3XF, Siokra 253B3XF and Sicala 320B3XF. This is the first time Sicala 320B3XF has been grown in the Central Highlands. This is in a back to back cotton, furrow-irrigated field. Watered up at the beginning of September, establishment was affected by a cool flush, seedling disease and wireworm. Despite this, Sicot 619B3XF stood out with its early vigour compared to the other varieties. It had 70% establishment on average, followed by Sicala 320B3XF at 64%. All varieties began flowering by the 2nd week of November at 12.7-15 nodes and between 30-37cm in height. At 5.3-7 Nodes Above White Flower (NAWF), it was evident the cotton was feeling the squeeze from the high insect pressure and disease through establishment and squaring. By mid-November the trial was showing good signs of recovery from the earlier setbacks.
