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)...

" Grower adoption and implementation of strategies to manage soil water repellence in farming systems.. No detailed time-series soil surveys have been conducted to confirm the perception that water repellence is increasing the expression of the constraint is easier to diagnose than most because of the obvious nature of the impacts on establishment, water infiltration and variable soil wetting... The grower intends to continue mouldboard ploughing and using the paired row seeder which is also a good implement for seeding ploughed areas...

The experiments are run over 4 years to test the water use efficiency, productivity and riskiness of: (i) a range of continuous cereal systems and the decisions around inputs, timing and agronomy; and (ii) potential break crop systems; across soils of differing potentials... Comparison with the non N-limiting yield potential estimated using the APSIM model of 5.05 t/ha in the swale, 6.06 t/ha in the mid-slope and 5.12 t/ha in the dune, suggests the actual yields are very close to potential yield in the wheat following pasture in the swale but well below for all treatments in the dune and mid-slope (Figure 3)... A build-up of fertility in the swale where fertilizer applications have been uniform across soil types in the past and the swales have under-performed in the dry years has meant that N was not limiting in this soil type and potential yield was attainable in the wheat following pasture where a disease break had been provided...

Summer rainfall in excess of 25-30 mm in a single event is usually stored in the subsoil, so a rainfall event of 100 mm would leave about 70 mm in the soil... Increased soil water at sowing may lead to higher yields, particularly in soils with higher soil water holding capacity, or in dry growing seasons... Modelling studies for the NAR suggest that on average, soil water storage on May 1 is reduced by about 10 mm if summer weeds are not controlled (Table 3)...

Choose resistant varieties to ward off stem rust.. While fungicides may work on leaf rust and stripe rust, which affect the leaves more than the stems, they are less effective on stem rust, especially in thick canopies where they may have trouble penetrating and contacting the stems... Figure 3: Stem rust appears on both the leaves and stems of the plant running parallel to the long axis of the leaf or stem...

The stubble management decisions each of these growers made in 2010-2011 were unique to the individual and were influenced by the combination of experiences, cropping systems, agronomic and logistic challenges, and commitment to full stubble retention... The value of grazing crop stubbles to farm profitability was overestimated by the ME value of the intake the value of grazing crops cannot be predicted using energy intake from stubble... Finally the burning of stubbles also contributed to weed 26Australian Glyphosate Sustainability Working Group, Australian Herbicide Resistance Institute (2013), 9 Oct 2013...
