Field peas trials

The objective of this trial is to demonstrate that growing canola (with effective weed control options) followed by a high value legume (with higher economic value) can lead to an effective and profitable double break crop sequence. The contribution of an early sowing date versus a traditional sowing date to increase the profitability of these crops will also be evaluated.

This project will determine the economic value of growing canola followed by a high value legume, and the impact of this rotation on the grain yield and profitability of a cereal crop in the first year following the double break crop sequence.

This was a small trial in which alternative break crops were sown into a deep sand.

Presence of increased seed dormancy in this grass weed species has enabled it to escape pre-sowing control tactics used by the growers. This explains why barley grass is a problematic weed in cereal crops. However, in some locations like Port Germein and Baroota districts, it has now become largely impossible to control in pulse crops. This islikely due to the presence of group A (fop & dim) herbicide resistance. Currently in these locations barley grass control is reliant on growing Clearfield wheat and the use of imidazolinone (group B) herbicides. This management strategy is at high risk of collapsing from the additional development of group B herbicide resistance. Previous studies have shown that resistance to group B herbicides can develop relatively quickly. Presence of large densities and repeated exposure to group B herbicides could rapidly lead to group B resistance in such barley grass populations. The extent of this resistance needs to be understood and effective management strategies to manage resistant barley grass in pulse crops developed.

GRDC has funded a programme to address this issue and one of the projects within this programme is developing an improved understanding and implementation of management practices for brassica and pulse crops, pastures and other options to reduce the risk of crop failure and improve whole farm profitability in low rainfall south-east Australia.

To test whether disturbance seeding systems overcome water repellence in non-wetting gravels and other soil health issues over time.

To compare three legume crops in farmer scale seeding strip trials at three locations in the Albany Port Zone. Demonstrations will compare several legume crops in different soil types in different micro-environments. The same trial sites will be monitored in 2019 to determine the effects (positive or negative) of the legume break crop on the subsequent barley/wheat crop and soil nitrogen status. The legume demonstration trials will provide growers with current agronomic information for pulses/legumes as a break crop in farming systems for the Albany Port Zone. Information from both the legume demonstration and effect on the subsequent crop will complement the Crop Sequence Calculator Workshops to be run concurrently by Farmanco.
