AIM To investigate the use of wetting agents, applied directly to canola seed to understand its impact on crop establishment and yield in water repellent soils. These results will also be used to benchmark the effectiveness of seed coating wetters against the current in-furrow banded applications, with relation to both ease of operation and cost-benefit. […]Continue reading "Canola establishment- Is it improved through the application of wetters to the seed in marginal conditions"
We all know that mulesing is becoming socially unacceptable, and worms are increasingly resistant to current drenches. Many producers who have stopped mulesing have been successful, but it is fair to say that many have also failed to sustain the change because the management issues were too difficult. The approach to shifting to non-mulesed systems […]Continue reading "Supporting shifts to non-mulesed systems: Annual Summary"
AIM Numerous compound fertiliser products can supply phosphorus (P) to crops, each with a unique P content and bulk density meaning differences in rate and granule distribution to supply the same P. Product choice has cost and logistical implications. We investigate the agronomic response of Magenta wheat to various rates and compounds of P fertilisers […]Continue reading "Establishing phosphorus compounds and nutrient supply for wheat crop production – Large plot trial, Yornaning"
AIM To increase crop productivity on sandy soil types in medium to high rainfall zones through the incorporation of organic soil ameliorants; hay, stubble/straw and manure. The overall objective will be to encourage growers in the Central Wheatbelt region of WA to implement a form of incorporation of organic ameliorants on their sandy soils by […]Continue reading "Incorporation of organic soil ameliorants to boost productivity of sandy soils in the medium to high rainfall zones of the Wheatbelt of WA"
AIM 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 […]Continue reading "Pre-emergent herbicides and high density crop for barley grass control"
AIM To evaluate the grain yield and economic benefit of soil amelioration and controlled traffic practices on a broader range of soil types across the grain growing region of WA. CONCLUSION The treatments applied in this demonstration are to alleviate multiple soil constraints, including non-wetting, subsoil water infiltration, subsoil acidity and compaction. Prior to the […]Continue reading "Demonstrating the benefits of soil amelioration – Ripper Guage"
AIM To compare different rates of trifluralin incorporated by seeding on oats in the Wickepin region and its effects on weed control, germination, yield and grain quality. CONCLUSION This trial has now been conducted over four seasons (2017-2020). The results from the 2020 trial support the findings of previous years, with no relationship between trifluralin […]Continue reading "Effects of Trifluralin on Oats"
The project is designed around how to sustainably improve livestock productivity in the face of increasingly variable seasons. Our short length of season makes livestock enterprises highly sensitive to seasonal variation, which can radically impact their output. This creates a need for systems which can deal with tough, variable seasons, with effective yet flexible management. […]Continue reading "Tough Seasons Project"
The aim of the project was to reduce the impact of acidic soils on plant growth and test the most practical and economical methods of incorporation of lime on duplex soils in the Central Southern Wheatbelt and compare against common top-dressing practice. The objective is to give growers a greater understanding of different methods of […]Continue reading "Incorporating Lime to depth on duplex Wheatbelt soils"
Our aim was to 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. CONCLUSION The learnings from this site in 2020 have provided growers with […]Continue reading "Increasing the profitability of the double break rotation in the MRZ of WA Wheatbelt through incorporation of an early sown high value pulse"
The aim of the National Variety Trials (NVT) is to generate independent information for growers and industry about newly released varieties of field crops to the current commercial varieties grown in the area. BACKGROUND The NVT program has been designed to identify the highest yielding varieties, free from the constraints of nutrition and disease. As […]Continue reading "2020-2021 National Variety Trials"
