• Four oestrogenic sub clover varieties (Yarloop, Dinninup, Geraldton and Dwalganup) have been found in South East SA and Kangaroo Island pastures.
• Oestrogenic clovers can be responsible for reduced ewe fertility, difficult births, prolapse of the uterus, urethral blockages in wethers and udder development in maiden ewes and wethers.
• Growers are encouraged to assess their own paddocks for the presence of problem species, potential impact on their flock and the development of appropriate management strategies

• 2 seasons after the break crop being planted, significant yield benefits from the break crop are still being observed
• Significant interactions between the nitrogen requirements of wheat after the break crop were observed again in 2013 (also noted in 2012)
• Splitting nitrogen treatments after wheat and canola resulted in significant yield increases when compared to a single nitrogen application

• A strong trend was evident in this trial indicating that the new plant growth regulator Moddus Evo when used in combination with Amistar Xtra gave positive yield results. These results where beyond what could be attributed to antilodging with Moddus Evo and disease control with Amistar Xtra
• The addition of tank mix partners where not seen to be antagonistic to the results and in fact also trended positively however Syngenta recommends not mixing Flexi N or phenxy herbicides with Moddus Evo. The herbicide mix’s greater yields may have been linked to improved weed control.

• The fungicides Amistar Xtra and Cogito in this trial significantly reduced foliar disease levels providing significant yield increases in barley.
• The addition of Moddus Evo plant growth regulator provided a small incremental improvement on yield to the fungicides alone.
• The experimental in-furrow fungicide SYNSIF1 was not able to deliver disease control and hence yield improvements in this trial because foliar disease appeared after the useful residual of the product had been exhausted.

• Acidity was found to be more widespread in the USE than expected, with 15 of the 18 paddocks examined containing zones of soil with pH below 5.5
• Sandy loam and clay soils used for cropping were acidic
• Clay spread shallow sandy soils used for cropping were acidic
• Clay spread deep sandy soils used for grazing were acidic
• The target soil pHCa range is between 5.5 and 6.5; lime needs to be applied now to combat current and future acidification.

• Sow as soon as soil temperatures reach the recommended minimum for the crop type
• Moisture probes are a valuable tool for irrigation scheduling and monitoring soil moisture
• Understand and plan agronomic and irrigation requirements of your selected crop. Short season crops will require less water and may fit into a ‘double cropping’ program.

• Phosphorus fertilisers are expected to get more expensive as demand overtakes supply.
• Fertiliser applied phosphorus can be lost rapidly on some sandy soils. There are some simple tests that can be done to indicate the risk of this happening.
• In other soils, phosphorus is fairly immobile and won’t be lost to leaching.
• Building up the soil reserves of phosphorus will make P more plant-available, regardless of how or when it is applied.
• The total phosphorus in the soil has value to you, not just the more readily available phosphorus.
• Generally if you maintain a balanced phosphorus regime, you will use everything that you apply in the long run.
• Phosphorus is fixed by most soils. This is generally a good thing as it prevents leaching losses, so unless you have ‘high risk soils’, don’t be concerned about “lockup”.
• Don’t buy into alternatives to phosphorus fertilisers that claim to improve access to phosphorus stored in the soil.

• Trial data from the fast track project is still to be analysed. The following key messages are from trials conducted by Steve Marcroft in conjunction with the fast track project.
• Normal crown canker occurred as predicted, i.e. high leaf infection resulting in crown canker. Fungicides applied at the 4-6 leaf growth stage were effective at reducing crown canker. Cultivar resistance was also very significant.
• Upper Canopy Infection did not develop as badly as anticipated with the many leaf lesions noted early in the season.
• Pod infection was not influenced by fungicide applications up to 30% bloom, but flowering date was very significant.
• Fungicide was effective at reducing Upper Canopy Infection. Fungicide was effective at significantly increasing yield, however the most effective timing for fungicide application was variable for each of the disease symptoms.
• The sclerotinia spray application timing (30% bloom) appeared to be a good timing for Upper Canopy Infection control. However this work needs to be repeated in seasons that are conducive for severe Upper Canopy Infection symptoms.

Trial conducted to continue evaluation into the use of chemicals to manipulate broad been plant architecture without decreasing yields.
• Unseasonably dry and warm conditions and resulting poor yields were not conducive for conclusive results.
• In three years of trials Ethephon reduced plant height without a significant yield penalty.

• Agronomic or chemical assisted canopy management could have significant benefits to fungicide penetration and efficacy, disease intensity, grain yield and harvestability.

• Two canopy management treatments (simulated grazing and a low rate of glyphosate) suppressed plant height with no significant effect on grain yield.
• All other treatments either caused a yield penalty or did not suppress plant height.
• Several herbicides, including glyphosate and imazamox show promise as growth regulators, but require revision of application rates.

Post-emergent herbicide was scored for visual damage on 26th September 2012. These results have been combined with yield data and the results will be discussed with Pulse Australia to look at future work in determining herbicide permits for Broad Bean crops.

• Spader generally produced a positive yield response (grain and biomass) on sandier soils that had previously been clay spread and /delved.
• The inclusion of organic matter prior to spading generally improved the level of response to spading.
• Know your soils that you are spading; (not recommended on shallow red loam soils over clay where there is a sodic A2 horizon)

• As long as enough plants are established, canola can be sown at low rates as the plants compensate so well. Lodging was reduced by lower sowing rates. 
• Using retained hybrid seed for sowing resulted in lower grain yeilds and increased plant losses from blackleg.
• Winter types of canola from international sources may allow us to get increased grain yeilds in seasons when we can sow early. 

In 2017, there were three canola variety trials sown across the South East region of South Australia: located at
Keith, Bordertown and Frances. The site at Keith evaluates early season varieties, and those at Bordertown and
Frances evaluate mid-season varieties. Both sets of trials have similar sowing and harvest times and have a similar
complement of varieties, although there may be several early maturity varieties in the early series that are not
tested in the mid-series, or vice-versa. The data from the 2017 Bordertown canola variety trials has not been
released.

• The yields for the Clearfield (imidazolinone tolerant) variety time of sowing 1 (TOS1) trial averaged 5.48 t/ha (see Table 2a in attached trial report).
• There was no significant difference in yield between the two varieties sown.
• The yields for the Clearfield (imidazolinone tolerant) variety time of sowing 2 (TOS2) trial (Table 2b) averaged 5.56 t/ha and ranged from 6.32 t/ha (Pheonix CL) down to 5.18 t/ha  (Banker CL).
• There was no significant difference in yield between the varieties. 

There are no NVT Canola sites in the lower south-east and Millicent is seen as important in evaluating canola varieties in a high rainfall environment. 

Different fungicide applications didn’t result in a significant difference in grain yield, however there was a large difference in the amount of internal blackleg infection.

• Hyola 50 produced high grain yields compared to other conventional varieties.
• Better yielding Clearfield varieties included 46Y83, 46Y78, 45Y82 and Hyola 571CL.
• Better yielding TT varieties were the Monolas (specialty types), plus several new hybrid TT varieties
• Several varieties that have been grown for a while are now becoming more affected by blackleg so check on fungicide options plus isolation distances from last years stubble.

Irrigators should be advised by policy makers in the strongest possible terms to utilise continual logging soil moisture monitoring in their irrigation management plans. Soil moisture monitoring should not be viewed as an optional extra in an irrigation system but rather as the control centre that determines when to irrigate and how much to apply. The role of irrigation for crop production and salinity management requires soil moisture monitoring to determine the optimal time and volumes to achieve measurable objectives. Further research is needed to qualify and quantify the use of salt leaching irrigations as well as the use of gypsum applications to manage surface compaction created by stock and irrigation impact. White clover seed producers need to improve their attention to irrigation efficiency and focus on the net $ return/ML of irrigation applied. They are also advised to review their agronomic practices including paddock selection and rotations to aid in mitigating their current high end herbicide use on the white clover seed crops.

• Significant yeild increases were measured at Conmurra by controlling aphids to reduce the impact of BYDV
• A range of fungicide treatments, applied at GS31 9increased grain yeild in wheat at Conmurra by about 2t/ha
• High levels of black point occured at Millicent and allowed good ratings to be made. 

•  Significant yield increases were measured at Conmurra by controlling aphids to reduce the impact of BYDV.

•  A range of fungicide treatments, applied at GS31 increased grain yield in wheat at Conmurra by about 0.8 t/ha

•  High levels of black point occurred at Millicent and allowed good ratings to be made. 

At the higher rainfall sites such as Conmurra, consideration should be given to spraying to control aphids in order to reduce the early infection of cereals by BYDV. At lower rainfall sites such as Frances this may only be a viable proposition in years with high summer and autumn rainfall that may allow increased aphid survival. The development of new varieties with increased tolerance to BYDV will reduce this need to spray. CSIRO has wheat lines in their breeding program that have this tolerance. While fungicides would normally be used when disease is present, there are some circumstances where yield increases can be recorded even in the absence of disease. 

The GRDC-funded Australian Herbicide Resistance Initiative recommends the use of chaff carts as part of a 10-point plan to beat crop weeds on the WeedSmart website.

• Positive crop production responses still remain at Cadgee five years after amelioration treatments were applied.
• Application of clay improved establishment and flowering biomass, regardless of incorporation depth (shallow, 10 cm and spaded, 30 cm), compared to the control and the spaded lucerne treatments (see Fig. 1 in attached trial report).
• Grain yield response to clay application increased with the depth of incorporation, and were doubled in the spaded clay + Luc treatment compared to the control, adding 1.58 t/ha in 2018.
• Over the long term, this treatment has produced an additional 95 % grain (4.5 t/ha) since 2014 (four years grain data; Fig. 2). 
• Changes in soil chemical, hydrological and physical characteristics as a result of spading and lucerne and clay addition were the focus of 2019 soil measurements at the site.
• A full report detailing temporal trends and long term soil fertility changes will be released soon.
   

• Incorporating clay into the sand has led to yield increases that are improving with time.
• Yield response to clay application increased with the depth of incorporation; a cumulative increase of 0.74 t/ha (23%) over the control was achieved when clay was incorporated in the top 10 cm (Fig. 1 Shallow clay), increasing to 1.41 t/ha (44%) when the clay was incorporated to 30 cm (Fig. 1 Spading + clay).
• A similar response was achieved when 10 t/ha of Lucerne hay (organic matter (OM)) was spaded in, resulting in a 1.62 t/ha (50%) increase in yield (Fig. 1 Spading + OM).
• The combination of OM plus clay gave the best grain yield result in all years, with a cumulative 2.95 t/ha (92% increase) achieved across the 2014, 2015 and 2017 seasons (Fig. 1 Spading + Clay + OM).
• Spading alone led to cumulative decreases in yield of 0.39 t/ha (-12%), which is in contrast to results on Mallee sands, where the effect of spading has remained positive over time.
• Changes in soil chemical, hydrological, physical and biological characteristics as a result of clay and OM addition are the focus of 2018 soil measurements at the site.
• The response to deep disturbance and placement of OM and nutrition, in contrast to spading, is the focus of future research conducted by PIRSA at Murlong on the Eyre Peninsula in 2018.

The penetrometer measurements show that the nil treatment at both sites had a harder soil profile in the upper 20 cm at Hannafords (clay loam) and down to 35 cm at Jacobs. The reason the Nil treatment at the site of Hannafords shows lower resistance at depth is because this zone was waterlogged (water perched on the clay layer), showing that the ripping and spading have relieved some of the waterlogging. 

Ripping has done a very little to increase grain yields at the Frances site. The application of gypsum has generally increased grain yield by 15-20% over the untreated control treatment.

Because a crops ability to produce and finish is so tightly linked to how much water is available to it a simple yield forecast combined with how much water a crop still has left to access in the soil is surprisingly informative when it comes to reducing risks associated with forward selling decisions. At any point in the growing season it is surprisingly easy to use the data to see if the crop has access to enough water to finish, or if more rainfall is needed to reach a target yield. The graph below shows and compares the yield forecasts from each of the sites this year from when the soil probes were installed up until 20 Jan 2017.

There were no snails found in grain samples at three of the four locations were samples were taken. As such, it is possible that spatial variability and snail density may have a greater impact on snails numbers in grain samples than harvesting method. Site variability is a key issue and more information around how sites can vary is demonstrated in the work by SARDI at Lake Hawdon in the GRDC Stubble Initiative pest management guideline.

• No significant difference was found in protein results
• This is a difficult product to demonstrate using small plots as the benefit of nitrogen stabilisers is often shown improving the average result over a complete paddock.

With increasing pressure on rotations, there are a number of forage options that can be considered;

• On higher fertility sites, with better N levels-  Annual ryegrass such as Drummer and Grassmax as well as forage cereals such as Graza 80 and 51 are an option
• Brassicas (Leafmore) should be avoided on canola stubble
• On lower N sites, Blaza Crimson Clover,  Laser Persian Clover, Zulu Arrowleaf clover and Bolta Balansa grow reasonable hay and fix Nitrogen
• Further work needs to be conducted to evaluate competition value (esp with Wimmera RG) and yield benefits to following crops.   

• A range of forage varieties were grown as rotational options at the MFMG site at Frances.
• Drummer Annual tetraploid ryegrass (6.482t/ha DM) grew the largest amount of dry matter, followed by Graza 80 (5.491t/ha DM) and Grassmax (5.099t/ha)
• The annual clovers grew signifcantly less dry matter, with Laser Persian Clover growing (3.025t/ha DM), Zulu Arrowleaf (3.008t/ha DM) and Bolta Balansa (2.977t/ha)
• The cereal/grass based options grew more DM and offered more competition, but legume & broadleaf crops offered different herbicide options, disease breaks and in case of legumes, nitrogen fixation.
• More work required to show possible yields, both as monocultures and as mixes for rotational options

Due to unforseen circumstances, results for 2011 aren’t available for the Seedmark pasture evaluation sites. Seedmark do however look forward to continuing their work with MFMG in 2012 to explore the most appropriate Forage/Pasture rotation options.

The Field Days did however see the release of the new pasture variety “Monti” bred and developed by SARDI’s pastures group and released by the Australian Pasture Alliance (APA), an alliance between SARDI and Seedmark. Struan based SARDI researchers Andy
Craig and Freya Hawker lead the development of Monti with an extensive evaluation program run across a number of research site for the last 4 years. Below are some photos from the event.

• A range of forage varieties were grown as rotational options atthe MFMG site at Frances and Conmurra. 
• At Conmurra and Frances,the highest DM producing forages were annual ryegrass; R2 tetrapkhid annual ryegrass (12.28 t/ha DM) at Conmurra and Grassmaar Diploid annual ryegrass  (7.53 t/ha DM), primarilty due to their ability for a winter cut. 
• The best annual clovers at both Conmurra and Frances include Zulu II Arrowleaf (6.46t/ha and 3.93t/ha) and Bolta Balansa (6.27t/ha and 4.11t/ha).
• The cereal/grass based options generally grew more DM and offered more competition but legume and broadleaf crops offered different herbicide options, disease breaks and in the case of legumes, nitrogen fixation. 
• The legume and brassica varieties produce forage of a higher quality than that of cerels and grasses, which provides greater benefit to grazing animals.
• More work required to show possible yields both as monocultures and as mixes for rotational options. 

• The best yielding winter cultivars yielded similar to the best yielding spring cultivars despite a month difference in flowering date.
• Winter barley shows promise but we are still learning.  Strategies utilising Nitrogen, Plant Growth Regulators and Grazing need development to manage the increased biomass production and to improve the conversion of biomass to grain yield
• Early sown winter barley is a different agronomic system. The farming system benefits of winter barleys such as grain and graze, improved disease resistance should not be overlooked
   

• Antas sub clover (brachcalnium type) grew significantly more DM than other sub clovers - a 58% increase in dry matter on Trikkala.
• The more biomass you grow, the more nitrogen you fix. Using rules of thumb (25kg/ha N per 1t DM)
• Generally speaking earlier flowering varieties will grow more dry matter early, while later flowering varieties will make most of late rains. In practice a spread or mix of flowering dates may be prudent in a paddock situation.
• More work required to show possible yields, both as monocultures and as mixes for rotational options. 

• Antas Sub clover (bracycanium type) grew significantly more DMthan all other sub clovers, ( 7.94t/ha at Conmurra) an increase of 80% over standard Trikkala Sub Clover.
• The morebiomass you grow, the more nitrogen you fix. Using rules of thumb (25kg/ha N per 1t DM)
• Generally speaking earlier flowring varieties will grow more dry matter early, while later flowering will make most of late rains. In practice, a spread or mix of flowering dates may be prudent in a paddock situation. 
• More work required to show possible yields, both as monocultures and as mixes for rotational options. 

• Seasonal conditions can affect the disease complexes that exist for sub-clovers in any season (eg. the drier summers in 2014 & 2015 would be expected to cause a higher incidence of Rhizoctonia, whereas the wetter season in 2016 saw Pythium sp., Aphanomyces sp. and Phytophthora sp. more likely to be the dominant diseases).
• Current sub-clover establishment management practices (knockdown herbicide, cultivation, use of Apron seed dressing and sowing newer varieties or those that are widely adapted to the region) appear to be reducing the risk posed by root disease across the region.

• Sowing late into a high disease burden may offset any benefits of varietal disease resistance or the benefits of chemical control methods (i.e. seed treatments).
• Seasonal conditions can affect the disease complexes that exist in any season (eg. the drier summers in 2014 & 2015 would be expected to cause a higher incidence of Rhizoctonia, whereas Pythium sp., Aphanomyces sp. and Phytophthora sp. are likely to be more dominant in wetter seasons).
• Varietal differences were observed in establishment and persistence, however it is yet to be determined if this was due to root disease tolerance.

• The timing of brownout had no significant effect on the germination rate. This may have been due to a simulated “cultivation” immediately prior to sowing.
• Significant differences were found in the germination levels between varieties; Woogenellup is an older variety that is thought to be more susceptible to root diseases. The varietal difference suggests that root disease may be an issue across the region.
• Demonstration site responses to metalaxyl seed treatments in sub-clover germination suggests that root disease may be present and affecting establishment and persistence.

• There is a range (from susceptible to moderately susceptible) in varietal resistance to eyespot in long season wheat varieties commonly grown in the South East. Although this range is small it is large enough to influence damage due to eyespot.
• Know the eyespot inoculum levels (which indicate the risk of yield loss) in paddocks being sown to cereals and use this information to assist in variety selection.
• Avoid sowing the susceptible varieties Wedgetail, Kiora and Forrest in paddocks which have high eyespot levels.
• Trojan, Brennan and Manning are generally more resistant (moderately susceptible) to eyespot than other varieties screened.

Findings are from one site in one season and more data will be needed before firm recommendations can be made.
• Where eyespot inoculum is present in paddocks at medium to high levels, avoid sowing Wedgetail and Orion. Trojan, Manning, and DS Pascal would be better choices, as would Compass if sowing a barley.
• Experience across 6 screening trials undertaken in SA in 2014 and 2015 indicates that some varieties (e.g. Trojan, Compass) are very consistent in their response to eyespot, but others (e.g.Hindmarsh, La Trobe, Corack, Shield) are not.
• Cereal types and varieties with weak straw are more likely to be at risk of lodging (and harvest difficulties) in the presence of eyespot than those which have good straw strength. Plant growth regulants might assist in reducing lodging issues.
• The range of susceptibilities shown within the varieties screened should provide a good base for breeding programs.

• Know the risk of yield loss from eyespot before sowing a cereal - inspect stem bases (lodging does not always occur) in a previous cereal crop or take soil samples pre-sowing and submit them to PreDicta B for analysis.
• Select less susceptible varieties which are well adapted to the area - untreated they will perform better and they may also be more responsive to fungicide application, particularly where disease pressure is high. Avoid varieties with weak straw strength as they are more likely to lodge when affected by eyespot.
• No fungicides are registered at present for eyespot management, but a number are in the process of registration. Once these are registered - use the correct rate (lower rates can be less effective); apply before canopy closure (GS30-31 is usually recommended); use high water rates; target the base of the plant.
• Delays (due to waterlogging) in fungicide application until after early stem elongation may reduce eyespot incidence and severity but may not give a yield response.
• Inoculum carryover is unlikely to be influenced by variety resistance alone but is likely to be reduced where a fungicide is applied prior to canopy closure. Greatest reductions in inoculum carryover were seen where two fungicide applications were made (tillering plus GS30-31) or where one fungicide application was made to a less susceptible variety.

• This is the first quantitative information we have for the effects of varietal resistance and fungicide application and timing on eyespot expression and crop yield in the South East. These preliminary recommendations will become more robust as we gather more information.
• No fungicides are registered at present for eyespot management, but it is anticipated at least one registered product will be available for use in the 2017 season. Applying fungicides for eyespot management reduced eyespot expression and increased yields in the trials at Kangaroo Inn.
• Select more resistant varieties – untreated they will perform better and they may also be more responsive to fungicide application, particularly where disease pressure is high.
• Delays in fungicide application until after early stem elongation (recommended timing, as the canopy is still open enough to allow good coverage of the stem bases) may reduce eyespot incidence and severity but may not give a yield response.

• Seasonal conditions were the major influence on faba bean performance.
• Earlier sowings were beneficial in 2015, with significantly increased yields and grain weight.
• Extremely dry spring conditions and a short harsh finish mean results should be interpreted with caution. Long-term data and additional information should be considered when making varietal or agronomic decisions.

• Grain yields of beans were lower in 2012 in than previous seasons, averaging 3.6t/ha at Bool Lagoon.
• All varieties showed higher yields sown early.
• Later maturing varieties PBA Rana and PBA Kareema performed similarly to other varieties in this trial in 2012, despite the low season rainfall.
• The three earlier maturing varieties (Farah, Fiord and Nura) showed increased yield from increasing plant density, while no yield response was seen in later maturing and larger seeded varieties (PBA Rana and PBA Kareema).
• Fiord showed the most response from varying plant density across the three seasons of trials.
• Crop-topping trials showed a 9% yield loss across all varieties from crop-topping at the milky dough stage of ryegrass in 2012 and caution is required with this practice in later maturing regions. No yield loss was generated from later treatments.
