Photo: GRDC Northern Panellists inspect GRDC-funded winter crop trials in northern NSW... The checklist gives growers a comprehensive 'to do list' that will help growers maximise the potential that each year offers so they will be satisfied when harvest rolls around and yield and protein levels come in... Rotations - top of the list is the selection of crops and varieties as rotations, summer and winter, have become essential to our farming system in terms of controlling weeds and diseases...

Early prediction of soilborne disease could cut losses.. DAFWA project leader Martin Harries said soilborne diseases were a major cost to the cropping industry, estimated to cause losses in WA of about $100 million per year in cereals alone... "There is scope to reduce these losses through management actions - such as choice of crop type or application of fungicide seed dressings - if these pathogens can be more accurately detected and quantified prior to sowing," he said...

Key Points Research into biological control of the costly root-lesion nematode could boost yields and reduce losses... The GRDC-funded research is exploring the potential of naturally-occurring soil organisms to suppress RLN... Dr Seymour says the research will result in the identification of the key organisms involved in the suppression of RLN in northern grain-growing soils and an understanding of soil chemical, physical and biological characteristics associated with suppressiveness...

In many cropping soils of south-eastern Australia the presence of nematodes limits field crop production... Recent reports by Murray and Brennan (2009 a & b) estimated that in south-eastern Australia alone, nematodes are currently reducing wheat and barley production by 4.9% ($98 million) and 5.1% ($42 million) respectively, with losses in excess of 20% possible in the absence of appropriate control strategies... Growers can minimise yield loss caused by the nematodes in two ways...

Readers interested in any of the new varieties are encouraged to research them further on the National Variety Trials (NVT) website at www.nvtonline.com.au/new-varieties.. Pulses PB Blitz is a medium red lentil suited to all current lentil areas and is the earliest flowering and maturing red lentil available... Ideally fits medium to very high-rainfall areas including irrigation, and exhibits excellent hybrid vigour...

Without appropriate management, diseases can severely impact on the yield and quality of wheat crops in the Wimmera region of Victoria... The Information Note first discusses the integrated management strategies that are required to protect crops from losses due to disease, and then discusses the important diseases of wheat in more detail... For some diseases, a single management strategy is effective, while for others a number of approaches need to be utilised together to ensure effective management...

3. Choose tolerant wheat varieties to maximise yields (go to nvtonline.com.au).. From our research, the optimal temperature for reproduction of Pratylenchus thornei is 22C; populations increased, although at slower rates, from 17 to 28C... We have also found reduced growth and yield of wheat and chickpea following canola in a low phosphorus soil (7 mg/kg Colwell P) in two separate 2-year winter crop rotation experiments...

" Nematode Tolerance relates to yield of the variety in the presence of the nematode... Variety will not lose yield in the presence of the nematode, even at high nematode densities... In the presence of high nematode densities in a paddock these varieties will lose up to 30% yield...

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 benefits of a strategic tillage operation exceed any agronomic costs due to damage to soil structure...
