Sustaining productivity of tropical red snappers using new monitoring and reference points

OBJECTIVES: 1. Analyse current monitoring and logbook data sets, as well as survey and other information,to establish whether these data provide sufficient power to develop critical indicators of fishery performance. 2. Provide a risk analysis that examines the use of age structure and catch rate information for development of critical indicators, and response rules for those criteria, in the absence of other fishery information. 3. Develop a monitoring program that uses commercial vessels from the fishery to provide independent data.

Completed tree improvement project focussing on delivering improved mahogany varieties for the plantation industry in northern Queensland.

High-value wood products from sub-tropical plantations

To refine the emerging silvicultural systems for sub-tropical eucalypt plantations to produce logs of acceptable dimensions and quality for processing into high-value solid and engineered wood products, while maintaining financial attractiveness for growers. The available resources are focussed primarily on sub-tropical Corymbia plantings.

Sustainable productivity improvements in allium and solanaceous vegetable crops in Indonesia and sub-tropical Australia

The most important vegetable crops grown in Indonesia, and particularly lowland coastal production, are the true shallot and chilli. These crops are usually grown in rotation with rice but are far more valuable crops and are increasingly in high demand. They offer an opportunity for small farmers to generate extra income, increase farm profitability and shift away from subsistence production. However, the yield and profitability of shallot and chilli production is severely limited by a range of agronomic constraints. This project aims towards raising the productivity of allium (shallot and garlic) and chilli/capsicum cropping systems. The methodology will include a benchmarking survey and review of grower practices. This will be supplemented with physical surveys of crops for disease incidence and efficiency of fertiliser use. Once surveys are completed in Indonesia and the important pathogens identified, recommendations can be made for disease management. This will include review of chemical usage in Indonesia and Australia to provide best management guidelines for the application of insecticides, fungicides and other chemicals.

Delivering superior forage oat varieties for sub-tropical Australia

This full application seeks ongoing funding for the Agri-Science Queensland's forage oat breeding program through the Meat and Livestock Australia Partners in Innovation program with Heritage Seeds as the Donor Company and the commercial collaborator. The focus of the breeding program will shift to the use of minor genes that confer partial resistance or adult plant resistance to leaf rust. Accumulation of several minor genes in a single variety should produce a high level of effective field resistance, and better durability of resistance, with less likelihood of a mutational change in the pathogen.
