In 2018, the Jerdacuttup trial site experianced significantly low rainfall for the growing season. Rainfall for the Janurary to September period in 2018 was 197.2 mm compared to 471.8 mm in 2017. This lead to the trial site being abandoned for the 2018 season. In 2019, the Jerdacuttup trial site experianced a significant frost on the 6th of Spetember which is highly irregular for the region. On the same date there was a moderate frost at the Speddingup trial site. |
