Strategic tillage renews on-farm profit potential.. The trials, led by Dr Yash Dang through the University of Queensland and the Queensland Department of Science, Information Technology and Innovation, showed that strategic tillage has the potential to lift both grain yields and gross margins, as well as maintaining soil health... Strategic tillage targeting a suite of weeds - fleabane, sow thistle, African turnip and feathertop Rhodes grass - has also enabled the Jensens cut seeding rates...

Strategic cultivation shows on-farm profit potential.. When the Hamiltons - Rodney and his son Sam - started hosting the trials on their 4046-hectare property in 2012, they were sceptical that ploughing the soil would not undermine the long-term benefits of no-till, which have seen increased yields and a lift in overall profitability... A recent survey of 55 growers and advisers in the northern grain-growing region showed that no-till systems have higher weed and disease pressure than farming systems where tillage is used...

Growers need not use high rates of clay or expensive incorporation methods when claying non-wetting soils to improve yields, new Western Australian research suggests... Dr Davies said that in the latest trials, wheat yields improved by at least 0.2t/ha when growing season rainfall was at least 300mm and low rates of clay were incorporated to a shallow depth at sites including Meckering, Bolgart, Badgingarra, Binnu and Balla... Dr Davies said when moderate (150-300t/ha of clay-rich subsoil) and high rates of clay (300t/ha or more of clay-rich subsoil) were incorporated to a shallow depth, there was little additional yield advantage when compared to the lower clay rates...

Yield performance of potential new Lupin varieties confirmed the yield gain required to justify their release.. WALAN2333 provides a significant yield gain where yields are above 1 t/ha while WALAN2385 shows significant yield improvements in all yield scenarios... The graph demonstrates a significant yield improvement on TanjilA...

"The modelling work follows field trials in southern areas of Victoria and New South Wales which have demonstrated a significant yield benefit from applying this strategy," he said... "The eastern states trials showed that early sown wheat crops yield more because less water is lost to evaporation; roots grow deeper and use more water; water is converted to dry-matter more efficiently; and a longer stem elongation phase increases grain numbers... "The modelling work, using the Agricultural Production Systems Simulator (APSIM), found that potential yield gains were highest in regions such as Esperance and Kojonup where there are more frequent early rainfall sowing opportunities and the yield potential is higher," he said...

Graphic showing yield increase trend over 115 years of wheat breeding.. Averaged over the four NSW trials (Michael Pfitzner, Rankins Springs; Jeffrey Muirhead, Merriwagga; and Jeff Savage, Barellan; as well as the Hillston trial), LongReach Lancer was almost double the yield of Federation... For example, prior to the release of varieties such as Condor, lodging was a significant problem in high-yielding wheat crops affecting yield and quality as well as dramatically slowing harvest...

Similar results were achieved with barley with yield responses to PGRs in two out of three years and a reduction in crop height recorded.. The results of the research suggest that PGRs may be more than 'opportunistic' in good seasons in the high rainfall zones but may be used regularly in the medium and high rainfall cereal zones of Australia... The results of the research have demonstrated that a combination of trinexapac-ethyl # and chlormequat # has provided consistent results in cereals (wheat and barley) applied at GS31...

" Economics of closing the yield gap in the Northern Grains Region.. A third measure to help growers make decisions to improve yield will be benchmarks for water productivity, otherwise known as water use efficiency, for different soils and scenarios for each part of the Northern Region... Workshops will involve growers and advisers in discussion of yield targets and ways of closing the yield gaps, along with the economics of improvements and putting it all together to make the farm and region more profitable and productive...
