AAC114: Assessing the adaptation of long season wheats in South Australia
There is potential to sow long season wheat varieties in many environments in South Australia in response to early season rainfall events. Main season, spring wheats can produce lower yield when sown early. Frost during stem elongation and the reproductive period is one risk when maturity of commercial cultivars is brought forward by early sowing. Grain quality and yield need to be considered equally to ensure profitability of early and very early sowing.

AC115: Seed to Store YouTube Clip Competition
The project successfully engaged school students in creating video clips on the grain industry, with 26 entries received. The Seed to Store competition generated positive coverage in rural media and encouraging feedback from participants. A third round has recently been completed for 2016.
AGT114: Heat research study trip to America
This project provided opportunities for Paul Telfer, of AGT, to make connections with international researchers to enable future research collaborations on heat and drought research projects.
DG1202: A new approach to grass weed control for durum wheat
This project discovered an integrated approach to improve grass weed control in durum wheat by providing detail on the best pre-emergent for use in durum wheat, benefits in increased seeding rates and larger seed size and the competitive ability of different varieties.
RS114: Publication of 2015 Farm Gross Margin and Enterprise Planning Guide for SA
The 2015 Farm Gross Margin Guide was published in February for use by crop and livestock producers in SA as part of their farm business planning process. The guide incorporates the latest information on input and output pricing to give estimates of the relative profitability of different farm enterprises.
S0213: Forage peas – a potential new break crop option for SA
New forage and dual purpose field pea varieties provide growers with an alternative break crop to vetch. However agronomic management to reduce blackspot disease risk and maximise biomass production will be essential to make the most of these new options.
S0713: Evaluating clethodim tolerance in canola
Applications of clethodim were found to strongly influence the growth and development of canola, ultimately impacting on grain yields and quality. The rate and timing of applications had a large impact on the severity of damage and yield losses to canola.
S1205: Cost-effective selection of high beta-glucan using molecular markers
The project discovered that the genes known to indicate high beta-glucan content in barley are different to those in oat, complicating the ability to develop molecular markers. It has, however, provided important foundation work for future research in this area.
S1207: Enhancing the grain yield and quality of oat under water deficits
Improved adaptation to drought, along with responsiveness to favourable growing years, will provide growers with both stable and responsive oat varieties. Ultimately this will result in an increase in the area sown to oats for a consistent and stable supply for the milling industry.
S1208: Resistance monitoring of ascochyta blight in lentils
Ascochyta blight of lentils can now infect previously resistant varieties Nipper and Northfield across SA and Victoria but fungicide applications can assist in limiting the damage from the fungus.
UA0313: XRF as a tool for measuring crop nutrient contents in the laboratory and the field
XRF technology has shown potential to provide rapid and cost effective analysis of selected plant nutrient concentrations in a wide range of crop types in southern Australia.
UA1201: Evaluating the agronomic and financial benefits of P-efficient cereal varieties
The difference in PUE between varieties has been difficult to observe. Considering current prices for fertiliser and grain, it would be recommended to achieve maximum yields through sufficient P applications and growing varieties suited for a region, rather than selecting potentially high PUE varieties. However, work is continuing in a new SAGIT funded project.
UA1203: Manipulating seed nutrient content to improve vigour and yield in wheat
Crop establishment and crop vigour were enhanced by using high quality seed but there was no yield benefit in manipulating seed quality when yields were below 2.5 t/ha. Therefore it is farmers in higher yielding environments who are likely to benefit most from using high quality seed.
YP1201: Testing innovative snail management techniques on the Yorke Peninsula
Snails have a significant impact on cereal crops in South Australia’s cropping regions, particularly on the Yorke Peninsula. Decades of research has been undertaken at great expense to the industry in the search for effective control methods. This research project found that baits do kill juvenile snails and an integrated program of appropriate stubble and weed management at pre-sowing will provide the best control for snails.
Brome Grass Bulletin published. Although brome grass is a major weed of cropping systems in SA, it can be effectively managed. The best approach is an integrated weed management strategy which aims to kill existing weeds, prevent seed set, deplete the seed bank and avoid reintroducing seeds in to the system. This bulletin has been designed to bring together all the information on brome grass and provide examples of how farmers are managing to stay on top of it.
Projects Completed 2014
S0311: Cost-effective doubled haploids for accelerating wheat and oat breeding
The project successfully regenerated wheat doubled haploids using technology similar to that used for commercial barley breeding. This is the first time such high levels of regeneration have been achieved using this method in Australia. The project also successfully regenerated oat doubled haploids at levels far greater than previously achieved.
PCT0111: Increasing economic performance using Precision Agriculture
Precision agriculture decision-support tools are useful in providing growers and agronomists a simple step-by-step guide to implement precision agriculture on-farm. An additional document – Soil Survey Decision Tree – has been developed to assist growers more accurately assess their own farming requirements.
MSF1201: Farmer groups to focus on innovative practices
Farmer groups in the South Australian Mallee addressed locally relevant issues and developed facilitated activities to improve productivity and profitability.
S1201: Demonstrating best management for rhizoctonia on Upper EP and Mallee
SARDI demonstrated the combined value of management practices which reduce the impact of rhizoctonia in typical upper EP and Mallee environments.
S1206: Strategies to reduce white grain on Eyre Peninsula
The fungi causing white grain can survive on infected cereal residues for at least 24 months. Rain-splashed spores from infected stubble can infect cereal plants, without causing symptoms in grain. Paddocks at risk of white grain are best identified through PreDictaB testing.
S0711: Matching seed source and target environment to improve cereal production in SA
Better crops require healthy, plump seeds. While the seed’s source does not affect the crop’s tolerance to stress, such as drought and salinity, it can improve yields under favourable growing conditions. Seed from saline soils should be avoided in non-saline soils as yield penalties may carry over into several successive crops.
S0511: Assessment of new vetch species for low rainfall cropping areas.
SARDI assessed four novel vetch species to determine their potential for release in South Australia’s low rainfall zone but they failed to outperform or offer any significant advantage over the standard common vetch variety, Morava.
Projects Completed 2013
S0601R: Barley germplasm development phase 2 – evaluation of bulbosum genes and implementation for barley improvement
SARDI demonstrated that wild barley species Hordeum bulbosum possesses new sources of genes which may provide agronomically-valuable traits such as resistance to leaf rust, scald and net form net blotch and tolerance to boron, salt and moisture stress.
S0111: Disease management workshops for pulse crops.
SARDI developed a disease management manual, ‘Management of pulse diseases in southern Australia’, and workshops on pulse and disease management were conducted in pulse growing regions.
S131OR: Field evaluation and development of advanced strand medic lines.
SARDI identified new medic lines with improves dry matter production and seed yield – up to 35% higher than benchmark strand medic cultivars, Herald, Angel and Jaguar.
SANTFA12-01: Ultra-high pressure injection to increase fungicide efficiency.
There was no increase in fungicide performance by ultra-high pressure injection compared to traditional seed dressing application.
PNP00001: Increasing the value and marketability of feed grains for the grains industry.
Growers can increase the value and marketability of downgraded cereal grain by selling based on its nutritive characteristics, rather than its receival grade.
