This project aims to develop DNA tests to quantify Free Living Nematode (FLN) groups in soil, which will be useful indicators of soil quality... Nematodes are useful biological indicators of soil health because they: occur in all soils; are readily extracted and identified; have a wide range of food sources; are ecologically and taxonomically diverse; and respond to changes in food sources, as well as soil physical and chemical properties Indices derived from nematode community analyses can be used to provide information about a soil ecosystem with respect to nutrient status, presence of p...
GRDC Taxonomy:
The Services to be completed by the Western Region Research Update Coordinator are to: Deliver a program advisers, consultants and agribusiness through an annual Agribusiness Crop updates (showcasing GRDC/DAFWA and partner R, D and E outputs)... Western Australian growers are urged to find out how cutting-edge research presented at the recent Agribusiness Crop Updates can help them on-farm... Issues facing Western Australian grain growers will shape the agenda of the 2012 Agribusiness Crop Updates, for which topics and speakers are now being sought...
GRDC Taxonomy:
The aim of the collaborative NSW DPI and Vic DPI project is to 'equally and fairly' provide advanced germplasm containing important new or improved traits to all Australian private canola breeding companies, to ensure that Australian growers have cultivars that allow them to compete effectively on world markets... The pre-breeding outputs from this project are: improved screening methodologies that breeders can incorporate into their programs; new germplasm with identified improved key traits that have a genetic basis; information on the genetic control of those traits; and molecular marke...
In mixed farming systems grazing of the pasture phase can be used to minimise weed burdens but for continuous croppers, or within the cropping phase of mixed farming, some tillage might be needed for integrated weed management... From an overall systems perspective, limited and strategically timed tillage could form part of a productive, sustainable system... A central question emerges : How much damage is done to soil by occasional tillage, strategically applied, in an otherwise no-till system We seek to investigate this question based on the hypothesis: That the agronomic and economic be...
GRDC Taxonomy:
GA will conduct research aiming to deliver useful molecular markers to wheat and barley breeders in Australia, specifically in the areas of improved resistance to biotic stresses in wheat and barley and improved end-use quality in wheat... Australian wheat and barley breeders, already international leaders in the adoption of molecular technology in plant breeding, need new and better marker tools to help them develop varieties with the combinations of traits that will be needed in future markets and environments... By adopting the outputs of this project the Australian wheat and barley bre...
GRDC Taxonomy:
The major outcome of this project will be changes in crop rotations with improved farm water use efficiency (WUE) and utilisation of land resources, increased flexibility in farming enterprises and potentially significant environmental benefits... The project will determine the most suitable fodder species to increase grazing potential over autumn and winter... Maximising utilisation of land and water resources with fodder crops: The most suitable fodder species to increase grazing potential over autumn and winter and fill the window between end of harvest and spring sowing of vegetable cr...
KEY MESSAGES Grazing of cereal and canola crops in winter reduced grain yield by between 8 and 21% at seven of eleven sites... Grain yield was unaffected by grazing at four of eleven sites... KEY MESSAGES Grazing of both cereal and canola crops in winter did not significantly reduce grain yield and quality in five out of seven on-farm trials in 2011 Grazing of both cereal and canola crops in winter provided between 157 and 509 DSE grazing days per hectare of grazing value..
" Agribusiness Trial Extension Network.. The aim of the project is to extend an existing program designed to test if low initial inputs will minimise the financial risk of growing crops in dry seasons but still allow for incrop inputs to be applied to achieve optimal yields... As many of the current rules of input use, such as when to apply P and how much seed to use, have developed in the last 50 years there is a need to reassess their appropriateness in today's.....
GRDC Taxonomy:
" Queensland RAC Coordination.. The Services are to facilitate the operation of Research Advisory Committees (RACs) in Queensland and provide information to the Northern Panel on matters relevant to grains R, D & E in the region from their 'on the ground' perspective... The scope of the services relates in particular to: < Keep browsing..
GRDC Taxonomy:
Sugar is the dominant crop in the region impetus to diversify the farming system with break crops is being driven by cyclical periods of lower sugar prices together with a pattern of yield decline associated with continuous back to back cane production that characterise mainstream Burdekin sugar production... The uptake of more diversified cropping practices has been limited in the Burdekin even though a diversified farming systems approach has been shown to offer considerable improvements for cane productivity and profitability in other regions (eg southern canelands)... Review and furthe...
