Optimising barley yields and quality in No-Till farming systems.. X Highest yields generally occur with row spacing narrower than 300 mm and the benefits of adopting wider row spacing need to be evaluated against the costs (in terms of lower yields)... At one site, there was a strong correlation between the variety ranking in terms of trifluralin effects on plant establishment and the ranking of varieties in terms of the effect of wide row spacing on plant establishment, suggesting the observed "tolerances" are more related to (unidentified) seed quality issues rather than genetic differen...

Low drought induced irrigation allocations and low winter and spring rainfalls over the last five years have led to farmers using water to irrigate wheat and other winter crops for survival in spring... The only growers able to target 8 tonnes have been the bore pumpers in the Hillston and Darlington Point district who have achieved crops with 8-10t/ha yields... Although the 8 tonne system uses more water at 685mm compared to the one spring irrigation at 420mm the gross margin per megalitre is higher...

We have used average prices for each crop: $200/t for sorghum, $250/t for wheat, $400/t for chickpeas and $700/t for mungbeans... At Gindie we produced an extra 600 kg/ha sorghum in 2011/12 and an extra 500 kg/ha chickpeas in 2013, which would return an extra $320/ha for the first 2 crops after application using average crop values... At Wondalli we produced an extra 500 kg/ha sorghum in 2008/09 followed by an extra 650 kg/ha wheat in 2011, which would return an extra $263/ha for the first 2 crops after application using average crop values...

The evolution of a farming system should be a function of logical business decision making since the majority of farmers will list profit as a key motivator... While the system that evolves is important, it can never be solely responsible for a profitable outcome... If we look at the skill level of the top 10% of farmers (based on return on capital) we find that their skill profile is very different to that of the average farmer (Figure 5)...

Understanding farmer decision making and adoption behaviour.. The model shown below describes factors involved in decision making processes... While the decisions made might not result in the optimal outcome, intuitive decisions are usually right if they 'feel' right...

Without applied fertiliser, crop 1 (sorghum) showed no response to the tillage treatments; crops 2 and 3 had lower yields in AT than SM, RT or NT; crops 4-10 had no responses; and 7 of the final 12 crops had lower yields in AT than SM, RT or NT... Results on the same soil type have shown that compaction can persist for 5 years after trafficking has ceased... Tillage had reduced the soil organic carbon content at 0-10 and 10-20 cm after 20 years of treatment application (Figure 5)...

Treatment with Reldan and use of the fumigant ProFume ( Sulfuryl Fluoride ) are the main control measures currently used in central storages due to the difficulty of controlling this resistant strain with phosphine... Fans should be compared under the back pressure they are expected to work under when in use on a silo full of wheat, canola or other grains...

Control inoculum levels and you control this disease.. If you only read this one sentence you will know a great deal of what there is to know in avoiding Yellow leaf spot (YLS) epidemics in the majority of seasons in SNSW, don't sow susceptible varieties into stubbles containing moderate to high levels of inoculum... Such as those described in Street and Brill (2012) in central NSW or Beard and Smith in Western Australia (2012) have demonstrated that a program of early and repeated spraying is required to minimise the potential losses of the disease in susceptible varieties...

Whilst there is anecdotal evidence to suggest that dry seeding has been widely adopted in Western Australia, especially in the lower rainfall agronomic zones, the extent and management of dry seeding are not well documented, particularly for wheat crops... The aims of the paper are to determine the extent of dry seeding across the agro-ecological zones of the Western Australian Wheatbelt, to uncover the trends of adoption by soil types, rainfall and crop species and to define the management practices and gaps in knowledge around the risks of dry seeding crops in Western Australia... In the...

The early research also showed that in dry environments the changes in total soil-N were equal to the N removed in crops, but in wetter environments there was more loss of soil N than removal of crop N, probably because of loss of soil N due to denitrification... Many of the long-term experiments discussed earlier showed that introducing pastures into the rotation stabilised the soil total N... Nitrogen balance and gross margin estimated for farms in southern NSW (Angus and Peoples (2012)...
