In this irrigated trial at Breeza, Sicot 714B3F was the top performer, recording the highest yield at 9.40 bales/ha, which was 1.84 bales/ha above the trial average. This was followed by CSX1257B3XF, which achieved a yield of 8.56 bales/ha. CSX1257B3XF recorded the highest fibre length in the trial at 1.27 and achieved strong fibre strength of 33.2 g/tex. Sicot 619B3XF recorded the highest fibre strength (33.3 g/tex) and uniformity (85.4%) in the trial. Establishment conditions were challenging, with dry planting, cold conditions, rainfall during emergence and BRR significantly reducing plant stand and impacting yield potential. Once established, conditions were favourable, with good heat, low insect pressure and strong fruit retention. Field variability and uneven establishment made variety comparisons difficult; however, normal-density varieties generally showed better emergence and early vigour, while varieties such as Siokra 253B3XF, Sicot 761B3XF and Sicot 746B3F demonstrated a strong ability to compensate where plant populations were reduced. Overall, despite a difficult start, the trial provided valuable insights into varietal performance, highlighting the importance of establishment, vigour and compensation ability under stress.
