This project will quantify the variability in seed weight from field samples of the weed annual ryegrass (Lolium rigidum) and quantify how seed weight of annual ryegrass impacts the efficacy of harvest weed seed control (HWSC) impact mills.

Making the most of phosphorus(P) fertiliser inputs: Managing spatial variability and long-term strategies (TCO6024)
The overall aim of this project is to increase the profitability from phosphorus (P) fertiliser applications and determine sustainable P fertiliser strategies. This project focuses on two key P management areas: improving applications in variable paddocks/landscapes and refining long-term P management strategies on highly P responsive soils. This project will build on the results from SAGIT projects TC219 and TC221. This project is a co-investment, with GRDC providing 50% of the total funding.
Drought preparedness using barley architecture and phenology for biomass production (SAR5124)
The project aims to better understand the plant characteristics, including phenology and architecture, required to maximise biomass production for barley in grazed, grain and opportunistic grain and grazed scenarios across variable rainfall seasons. A diverse set of elite and novel varieties will be tested by different simulated grazing treatments across low, medium and high rainfall zones of South Australia.
Specialised research seeder to advance management of soil biological constraints (SAR3424)
Field research projects on the management of soilborne diseases and rhizobia are severely constrained by the limitations of current research seeders. The development of a specialised research seeder will enable SA researchers to undertake world leading research to develop innovative practices to manage soil biological constraints in broadacre crops. This project is for Stage 1 of a three-stage process to 1. review, 2. design and 3. build a state-of-art research seeder.
Grains pathology internship (SAR3324)
The project will support a Grains Pathology Trainee to be mentored by experienced staff from the grains pathology teams within SARDI Crop Sciences’ Plant Health and Diagnostics program. The mentoring will include laboratory and field pathology training provided by SARDI cereal and pulse pathologists, extension of information through written means, such as SARDI’s Crop Watch, participation in regional field days, and other industry support for grains pathology diagnostics.
