In this dryland trial at Spring Ridge, Sicot 761B3XF was the top performer, recording the highest yield at 6.56 bales/ha. This was closely followed by Sicot 619B3XF, which achieved a yield of 6.55 bales/ha. Sicot 761B3XF recorded the highest turnout (48.16%) as well as the highest fibre length and strength in the trial, with a length of 1.19 and strength of 35.9 g/tex. CSX 1320B3XF also produced strong fibre quality, recording a length of 1.17, strength of 34.1 g/tex, and the highest uniformity at 83.7%. Sicot 619B3XF established well and demonstrated strong early vigour as a normal-density variety. Although turnout ranged from 42.77% to 48.16% across the trial, yield differences between varieties were relatively small, with less than 0.55 bales/ha separating the highest and lowest yielding varieties, highlighting the strong overall performance of all entries under dryland conditions.
