Strategies for cooling, aeration drying and maintaining grain quality Insect management issues in grain storage.. Investing in a legume crop not only offers a biological break for the control of pests and diseases, but also an investment in slow-release.. Rust Cairo is moderately resistant to rust ( Uromyces vicea-fabae) and is superior to the susceptible varieties Fiord, Barkool and Fiesta...
Topic Welcome Breaking the yield barrier in grain sorghum Agronomy for success in high yield sorghum years on the Northern Downs.. The study presents output from the APSIM model to quantify the effects of the various strategies... I believe a key factor in the success of many of today's leading agricultural enterprises has been their ability to have their children acquire an education and experience that will equips them to make a meaningful contribution to the business...
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...
Trangie Grains Research Update Precision farming, controlled traffic & farming systems.. Grains Research Update - Trangie August 2002 of weathering of Australian soils, resulting in a lower soluble mineral concentration in the soil water... Other issues Given the above results from our demonstration sites and issues raised concerning direct seeding and controlled traffic in the context of conservation farming, we believe more work still needs to be conducted to enable us and the machinery / adviser industry to more adequately offer advice to farmers on machinery / farming systems options...
Boomi Grains Research Update for Growers.. A case study from the Moree district Experiments conducted in the Garah and Gurley districts by The University of New England showed that the application of by-product gypsum to strongly sodic grey clays can greatly improve the profitability of dryland wheat production... Microbiological and chemical soil tests showed that the soil around the macropores is a richer environment than the bulk soil, and the difference between bulk and macropore soil increases with depth...
The paper is based on the concept that Controlled Traffic Farming (CTF) systems are the future of the grains industry all cropping industries... The paper discusses some of the important production drivers in the grazing operations, being pasture improvement, crop: stock land mix and stocking rate... Using single variant analysis we can see that profit was largely influenced by yield the variation in yield was heavily influenced by how efficient the water was used rather than just the amount of rain received across all regions...
Based on this, we estimate that water used by weeds in the wet weedy (+I+W) treatment up to the midfallow period was 593 x 1688 (biomass) / 10 000 = 100 mm; for the dry weedy (-I+W) treatment water use is estimated at 30 mm... The results showed that Zn uptake by plants and in the grain could be most improved by mixing Zn with N and P (as technical grade MAP and ammonium nitrate dissolved in water) in a single solution and injecting it into the soil to a depth of 40 cm... Results from our laboratory experiments have confirmed that fluid forms of P have very different physical and/or chemic...
Resistance to spot blotch is much less common than for net blotches and the efficacy of foliar fungicides in controlling the disease has not been evaluated in Australia... Grains Research Update - Foliar Diseases in cereals August 2002 twice during the flowering stage, depending on environmental conditions... Grains Research Update - Foliar Diseases in cereals August 2002 do this monitoring and to apply the fungicide...
Oil composition can be compromised and lead to a change in fatty acid profiles if the seed is harvested when too moist, the seed has been excessively thrashed, admixture / moisture and disease levels are too high or the temperatures in your silo reach 35 C plus for more than 3 or 4 days in a row... People in some areas have very low levels of awareness that salinity is a problem, and report a low level of salinity... The chemical fertility of soil is only one group of factors that need to be considered when producing a good crop and a good income...
Delaying the onset of stripe rust within a crop is the key to significantly reducing the risk of yield loss to this disease in 2005... Stripe rust specific seed treatments are not required and crops should simply be monitored early for the development of stripe rust and a foliar fungicide applied if severe early infection warrants it... With the exception of the 2002 drought year, yields were always higher in the LB treatment (Figure 3)...
