• The recommended field pea industry practice of P-Pickel T® seed treatment and 2 foliar fungicides of Mancozeb failed to significantly reduce disease infection levels or increase grain yield over untreated control treatments under high blackspot disease pressure in 2016.
• Early disease control applications (four weeks after sowing) were important for reducing initial blackspot infection levels at Minnipa, conversely later spring applications were important at the higher rainfall site of Hart.
• Over two consecutive years, a yield benefit of at least 15% has been obtained from application of new experimental fungicide actives over the current industry practice treatment of two foliar sprays of mancozeb.
• Further research is required to understand the interaction in efficacy between fungicides and timing of disease infection, together with the drivers of Ascochyta blight onset and progression in different field pea growing environments.

• SAGIT funded trials over the last 3 years have shown the potential of vetch on Eyre Peninsula, leading to the selection of an early flowering (90-95 days) line with increased winter vigour (SA 34876) as a new variety for low rainfall mixed farming systems.
• The last three seasons have been particularly good at Minnipa for both grain and hay production of vetch.
• Piednippie trials have not been as successful as Minnipa, but have still shown with the right management vetch could produce good hay, fodder or grazing on the grey calcareous soils.
• On Eyre Peninsula early sowing (mid- April) can achieve good yield and hay production but is heavily reliant on either good subsoil moisture or late follow-up rain.
• Herbicide choices for vetch are very dependent on local conditions so talk to your local agronomist about the best options available.

• The optimum agronomic sowing window for field pea coincided with high blackspot in many districts of South Australia in 2015.
• Under such high disease risk situations, growers in low rainfall areas may be best suited to choose alternative break crop options to field pea to avoid significant yield losses through delayed sowing or disease infection.
• Experimental fungicide treatments with greater efficacy than mancozeb showed improved blackspot control and significant yield increases over the nil and mancozeb treatments in 2015. Further assessment and application approval is still required.

• Field peas have proven to be the most reliable pulse option on the upper Eyre Peninsula with yields remaining the most stable across seasons.
• Under favourable conditions there is potential for alternative pulse crops to be successful.
• Paddock selection, soil type, time of sowing, pulse agronomy, marketing and storage options all need careful consideration when looking at growing alternative pulse crops.
• New varietal options offer earlier maturity as well as improvements in harvestability, disease resistance and herbicide tolerance over older commercial standards, aiding production and profitability.
• Higher value alternatives, such as lentils, may be a high risk option and pulse crops better suited to the region could still prove to be the most profitable option in the long term.

• Green cumin (Cuminum cyminum) is a tap-rooted herb grown extensively in India and the Middle East for its grain.
• It survived trials on Eyre Peninsula in 2015 sufficiently well to encourage another look.
• Alternaria fungal disease is a major threat.
• Its low and slow growth will complicate harvesting and weed control.

• Early sowing (22 April) had the largest positive impact on canola yield when comparing a range of treatments trialled in 2015, similar to results observed in 2013 and 2014. Sowing on 22 April improved yields up to 12%, depending on variety, compared to 29 April sowing date.
• Different management practices are needed to establish canola on different soil types under marginal moisture conditions. On a loamy soil at Minnipa deeper sowing (to 4 cm) produced the highest yields, whereas shallower sowing (1 cm) produced the highest yields at Piednippie, particularly with the smaller seeded variety Stingray.
• Trials at Piednippie in 2015 showed that yields up to 0.8 t/ha are achievable in a below average rainfall season, provided the crop is established early and achieves around 50 plants/m2 in open-pollinated varieties.
• Results from similar trials in 2013, 2014 and 2015 have all shown that the highest yielding canola has consistently come from plots with plant establishments of over 50 plants/m2 for open pollinated varieties and 40 plants/m2 for hybrid varieties.

• Canola yields of 2 t/ha are possible in an average growing season (decile 5) at Minnipa Agricultural Centre.
• The total application of 85 kg/ha N and 108 kg/ha N exceeded the 2 t/ha target, producing 2.13 t/ha and 2.22 t/ha respectively, and 62 kg/ha N very nearly achieved 2 t/ha (1.96 t/ha).
• Soil tests determined that 70-80 kg/ha N was available in the soil, including mineralisation, which predicted a potential yield of 1 t/ha.

• Canola can be an expensive crop to grow.
• Yields can be maximised by planting early in low rainfall environments.
• Retained seed from open-pollinated varieties has the potential to match yields of some hybrid varieties.
• Delaying nitrogen application until stem elongation (bolting) was not as effective as applying at seeding or early post-emergence.

• Vetch grain and dry matter yields were very good at Minnipa in 2015, the grain trial mean was 1.4 t/ha with the top lines achieving 2.1 t/ha, mean dry matter yields were 4.1 t/ha with the top line achieving 4.3 t/ha.
• The Piednippie SAGIT trial was poor, suffering from moisture stress post emergence which stunted growth and limited the potential once the crop received rain in mid-June, the site mean was only 1.1 t/ha of dry matter.
• Early sowing (mid-April) can achieve good results but is heavily reliant on either good subsoil moisture or follow-up rain.
• The new varieties, Volga and Timok continue to out yield all existing varieties in both grain and hay production on the EP.
• Herbicide choices for vetch are very dependent on local conditions so talk to your local agronomist about the best options for your conditions.

• There were very little differences between fertiliser treatments and methods of application (applied 2013) at Penong in 2014.

Early sowing (15 April) had the largest positive impact on canola yield when comparing a range of treatments trialled in 2014, similar to results observed in 2013. Sowing on 15 April improved yields up to 45%, depending on variety, compared to 13 May sowing date. Good seeding depth and the correct seed rate proved important in maximising canola yield at the sites trialled in 2014, but not to the same extent as time of sowing. Sowing at 4.5 kg/ha at a 2 cm depth gave a 13% yield improvement over sowing at 1.5 kg/ha at 1 cm depth. Achieving approximately 50 plants/m2 of triazine tolerant varieties and 40 plants/m2 of Clearfield tolerant varieties was needed to maximise canola yields in trials conducted at Minnipa Agricultural Centre in 2014. Using farmer retained open pollinated seed did not cause a yield penalty when compared to commercially purchased seed in trials conducted at Minnipa in 2014.

• CL Kord seed treated with EverGol Prime and 40 kg/ha DAP out-yields standard 40 kg/ha DAP and untreated CL Kord seed. Very little differences between other treatments at Penong in 2013.

• Early sowing had the largest positive impact on canola yield when comparing a range of treatments trialled in 2013. Good seeding depth and the correct seed rate were also important in maximising canola yields, but not to the same extent as time of sowing.

• Early break to the season triggers a very early canola sowing time (22 March) in a time of sowing trial at Minnipa.
• Disappointing yields and no stand out varieties in time of sowing 1 (TOS1) at Minnipa missing the full potential for early sowing due to shattering and mice damage.
• Exceptional yields in TOS2 Clearfield trial at Minnipa where Hyola 571 CL, Pioneer 44Y84 CL and Pioneer 43C80 CL all exceeded 2.5 t/ha.
• ATR Stingray, CB Junee HT and ATR Snapper are the highest yielding TOS2 TT lines at Minnipa.
• Hybrids Hyola 571 CL, Pioneer 45Y82 CL and Pioneer 44Y84 CL shine in the Clearfield trial at Witera yielding above 2 t/ha.
• ATR Cobbler, ATR Stingray and Tanami are the best performing TT lines at Witera.
• Oil content in canola is above 42% across all trials.

Additional N did not have an economic advantage in this season. Paddock and demonstration site suffered from the dry 6 weeks period mid season. Stem rust devastated potential 3 ton crop reducing yield by 50%. This combination resulted in poor yields, low test weight and high screenings. Good soil showed improved protein over deeper sand regardless of extra N applied. Extra N marginally improved protein but not enough economically to apply more.

• Two Clearfield varieties, Pioneer 44Y84 and Pioneer 45Y82, exceeded 2.5 t/ha at Mt Cooper.
• There were no standout varieties in the Triazine Tolerant (TT) and Conventional canola varieties at both Minnipa and Mt Cooper.
• Juncea canola and Biodiesel canola produced lower yields than in the past compared to traditional napus canola due to above average rainfall year.
• No significant difference between the newly released pea lines at Mount Cooper.
• Break crops were successfully grown at Penong in 2010.

• Variation for boron and salt tolerance in field pea germplasm was not associated with grain yield differences at Minnipa as a likely consequence of very low rainfall in 2008 and very high rainfall and Blackspot disease in 2009.
• Under favourable growing conditions the late flowering advanced PBA field pea line, 94-425*2b produced very high dry matter yields at the flat pod stage compared to other lines evaluated.
• Advanced field pea lines with a combination of higher dry matter and grain yield production were identified and potentially offer a dual purpose (grain and hay/silage/green manuring) option for growers in low rainfall environments and a way of managing some of the risk of production.
• Findings require further validation across years and environments.

• Axe and Gladius produced the highest gross income at Franklin Harbour.
• Correll and Yitpi produced the highest gross income at Mt Cooper.
• Pugsley and Yitpi produced the highest gross income at Elliston.
• Flagship and Capstan produced the highest gross income of barley at Mt Cooper.

• A high rainfall growing season favoured blackspot disease build up and generally later flowering pea varieties at Minnipa in 2009.
• Kaspa was 17% higher yielding than Parafield, its highest margin over this variety at Minnipa in 11 years of testing.
• Kaspa’s grain yield was reduced by 19% when sowing date was delayed from 30 April to 20 May, however no grain yield reduction occurred in the advanced PBA field pea lines OZP0602 and OZP0601 with this delayed sowing date.
• OZP0601 and OPP0602, despite lower performance than Kaspa in the MAC variety trial in 2009, will provide better adapted “Kaspa type” options for low rainfall environments when they become available due to their earlier and longer flowering periods.

• No stand out varieties with peas at Mt Cooper in 2009.
• Av-Garnet conventional variety yielded the best at Mt Cooper followed by the two Clearfield varieties, Hyola 571CL and 43C80.

• The first year of trials show that there is material with real potential to do well in low rainfall environments and develop lines which will be economic as break crops in future.
• In 2009, about 120 lines were trialled at Minnipa and Condobolin.
• At Minnipa with an exceptional season yields ranged from 1.7 to 2.9 t/ha, with an average over 2.4 t/ha.
• At Condobolin, under tough conditions, individual plots yielded up to 1 t/ha.
