The factors are important in trying to understand the trends measured in this project... Grains Research Update - August 04 Wellington investigations to either confirm traditional research or provide an opportunity to develop scientifically sound methodologies to compare what is happening in a real world situation... I believe using less fertiliser is better, to encourage better micro organism activity, but that's my guess...

Overall, our conclusion is that while many current uses of yield maps will tolerate low to moderate GPS error, the inability to procure accurate GPS signals will hinder the development of more sophisticated applications of the information for the interpretation of crop behaviour and machine guidance... SSC's limit crop production by limiting crop rooting depth limiting effective plant available water content (PAWC), as well as having direct toxic and nutrient imbalance effects 3... The proportion of the total seasonal water use which is used by a crop after flowering goes a long way to determining the yield and quality of the grain produced...

While a cereal crop can shade broadleaf weeds, the weeds will still move their leaves to get the maximum benefit from any sunlight reaching them through the crop canopy... Crops sown in an east-west orientation are less successful in suppressing the growth of broadleaf weeds compared with grass weeds... Crop orientation will have a greater impact on farms in southern Australia, compared to northern Australia...

The project was established to provide advice to breeders on how to improve the adaptability of crops in the high rainfall zone (HRZ) of southern Australia so that yields could be lifted closer to potential... Information from the project needs to be extended to growers to provide guidance as to the likely impacts of different management strategies on the germplasm currently available... 2. Better understand crop growth and development of existing germplasm in the HRZ Field experiments were conducted to provide information relating to how current commercial germplasm (wheat, barley, canola and pulses) captured resources and the efficiency with which these crops converted these resources to biomass and grain...

Previous cereal research work in northern NSW has focussed on in-crop nitrogen application as a "top-up" treatment with the greater proportion of N being applied to the seedbed... Work in 2006 and 2007 showed significant differences in canopy structure when nitrogen was delayed until stem elongation (GS31) but in both years that was no significant increase in grain yield compared to when N was applied at sowing... Figure 3: Influence of split N applications on grain yield from early and main sown EGA Gregory For the later sowing, results are very similar to those in 2006 and 2007 with split applied or N applied at GS31 maintaining grain yields but limited significant yield response compared to the seedbed N treatment (figure 3)...

Application of nitrogen to most crops will affect grain yield, grain protein or both, depending on the available nitrogen supply relative to crop demand... Soil analysis conducted recently have indicated that EC, sodicity and chloride content have increase in the root zone of some soils due to capillary rise arising from the extended dry period... Environment mean yield (t/ha) d) Reduced tillering Several years ago I proposed that the incidence of haying-off could be reduced by increasing the storage of stem sugars by several means...

tolerate grazing and can recover to produce a grain or hay crop; provide forage to fill the winter feed gap in the livestock cycle; and facilitate grazing as a canopy management tool... Dual-purpose crops are increasingly being used in the high rainfall zones (HRZs) of south-eastern Australia to provide additional winter forage, and there is growing interest in sowing dual-purpose varieties in the drier regions of southern and western Australia... a late application of nitrogen can help to optimise grain yields...
