This project will assist South Australian growers to increase pulse yields by managing paddock variation associated with soil biotic and abiotic constraints. Data generated will also form the foundation for a decision support model. Focus paddocks will be mapped for pathogen levels and rhizobia as well as physical characteristics including pH, salinity and soil type. These factors will be related to remote sensing imagery and yield maps to determine the drivers of variation.
This PhD project will look to develop multi-scale (regional to paddock scale) monitoring methods for canola pests and beneficials, both pre-season and during season. The results will allow for improved risk analysis and decision making for integrated pest management by farmers and agronomists, avoiding over-use of insecticides.
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.
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.
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.
