This trial is one of a series done over the past few years to assess options in limited water situations. It was planted in late October 2017 in a double skip configuration with single furrows between the plant lines. Water was run down these during the season and seven irrigations were done. Water use was around 5.6mgl/ha.
There was some slight phenoxy damage noticed in the early part of the season but the crop grew away from it well. The plants developed well and root growth was evident across the whole double skip area. The number of fruit on vegetative branches was high with over 40 bolls/m. Total boll numbers were just over 150/m and the average lint weight per boll was 2.37gms.
Despite the later planting the crop was picked on the 13th May 2018. Yields on this configuration were very good with Sicot 748 B3F topping at 8.43b/h broadacre. Fibre quality and grades were also excellent with Sicot 748 B3F having a 40 length with a grade of 11-2.
This site showed what production can be achieved in limited water years where the availability of land is sufficient to extend out planted rows.
