Barley grass is becoming an increasingly problematic weed in Western Australia. A GRDC funded project sought to increase the adoption of integrated weed management tactics for barley grass, by working with grower groups to develop regionally appropriate rotations for optimal control. 

Barley grass at high density reduces crop yield. However, GRDC project UA00156 (Seed bank ecology of emerging weeds) has highlighted that barley grass ecotypes in Western Australia are often short, and are likely to be highly sensitive to crop competition. Initial control with pre-emergent herbicides combined with high seeding rates in cereal crops may be sufficient to control this species.

This trial aimed to investigate pre-emergent herbicides and high-density crop seeding in barley crops. The trial was run in two separate fields in 2020 and 2021, on a single farm.

The aim of this field experiment is to compare the viability of different break crop options for the management of RLN (P. neglectus) and Rhizoctonia. This involved monitoring the RLN population in response to different break crops in the break crop year (2018), as well as under susceptible cereal crops in following years (wheat 2019 and oats 2020).

This experiment examined the phenology of 31 commercial varieties and newly released lines sown on two sowing dates at Wagga Wagga, NSW in 2019.

Annual ryegrass at high density reduces crop yield. However, this weed is highly sensitive to crop competition. Initial control with pre-emergent herbicides combined with high seeding rates in cereal crops may be sufficient to control this species.

The trial aims to investigate pre-emergent herbicides and high density crop seeding in a wheat crop.

This research was done to develop predictive formulas that can be used by growers to estimate in-season soil nutrients from soil samples taken at different depths and crop nutrient content from proximal sensing (PS) data.

The upper Eyre Peninsula (UEP) is a challenging environment for growers, due to the irregular rainfall patterns which are coupled with lower soil fertility. Additionally, calcareous soils with poor structure and low water holding capacity provide additional restrictions for plant growth, as growers currently use granular fertilisers which require good soil moisture conditions to enable the uptake of nutrients. Topsoils from calcareous soils may dry quickly after rain events, which may explain poor water use and nutrient extraction efficiency.

PS technologies have the potential to support grower’s nutrient management decisions by monitoring in-season soil and crop water and nutrient content (Allen et al. 2017, Arsego et al. 2017). PS uses a wide range of wavelengths to predict soil and crop nutritional status in a non-destructive, quick, and inexpensive way. PS technology is mostly limited to laboratory use. The development of small, portable PS devices may allow the use of this technology in farm paddocks in the near future. In this study, we combined different UEP trials to develop predictive models for PS for crop nitrogen, crop nutrient content and soil moisture.
