keY points a break crop is any crop sown to provide diversity to help reduce disease, weed and pest levels in a paddock... the decision to grow a break crop is also complicated by many interactions through the cropping sequences including disease and herbicide carryovers and economic issues such as capital investment for new equipment or storage... pulses and oilseeds can be damaged in a flight auger, and alternative designs including belt shifters are preferred...

Overall, the most prevalent virus was BWYV and in some locations more than 90% of symptomatic plants were infected with BWYV (Table 1)... GRDC Grains Research Update Goondiwindi, March 2014 used a PCR for Beet western yellows virus (BWYV), Bean leaf roll virus (BLRV), Phasey bean virus (PhBV) and Soybean dwarf virus (SbDV) to investigate host range of the virus species from a range of locations (Table 2)...

" Goondiwindi GRDC Grains Research Update Day 1 - Tuesday 4 th March Time Topic Speaker (s) 10:00 AM James Clark (Chair Northern Welcome Panel GRDC) 10:10 AM General plenary (Supported by North West Local Land Services) 10:10 AM 10:40 AM.. Overall, both models are acceptable for modelling soil evaporation over a range of soils and seasons provided accurate soil physical properties and starting water states are known... Overall, populations increased five times compared to before planting the summer crops, but remained below 250/kg soil (Figure 4)...

Farming systems which minimise the movement of soil and water will also minimise the loss of nutrients and pesticides... Overall, the only large difference was the lower Zn when superphosphate was applied... In summary, Mike has found a strategy to help him interpret his yield maps - and is now taking the same approach to other paddocks to maximise fertiliser savings...

Break crops could hold key to tap soil phosphorus reserves.. University of Adelaide research, funded by the GRDC, on break crops has demonstrated positive effects on phosphorus uptake and yield in subsequent wheat crops... Wheat following a break crop has a greater P uptake and higher yield than continuous wheat rotations...

Break crops could hold key to tap soil phosphorus reserves.. Wheat following a break crop has a greater P uptake and higher yield than continuous wheat rotations... There were three findings from the study: the effects of break crops on in-season P mobilisation, the lack of influence of break crops on pre-sowing available phosphorous in the subsequent season, and the greater P uptake and yield of the wheat after break crops...

Trials were undertaken to demonstrate the effects of rotation, fallow management, nitrogen levels, water availability and grassy weeds on crown rot and crop agronomy... Build-up of crown rot in paddocks should be assessed by monitoring late in the season... The experiment showed that grass weeds, even at levels that caused heavy yield losses, had a relatively small effect on crown rot in continuous wheat or in short rotations, where the dominant effect was the inoculum present in the wheat stubble...
