• The standard treatment in this trial, namely Sencor (metribuzin) 750WG plus TriflurX, provided no more that weak suppression of brome allowing substantial seed set.
• The trial demonstrates a new option for brome control in barley crops now available to growers, namely growing Scope barley and using Clearfield herbicides such as Intervix or Midas. Both products provided excellent to absolute control of brome, as well as silver grass.
• The trial also demonstrates that while the pre-emergence treatments alone provide only modest control of brome, their use in combination with Clearfield herbicides has the potential to improve the overall Clearfield performance. Their use is recommended for resistance management purposes and as a means of securing yield by reducing early weed competition.
• Achieving absolute control of brome grass by treatments that pay for themselves and deliver a surplus to users (of $45 – $150 per hectare) should make most Clearfield treatments highly attractive. Atlantis, Crusader and Monza each only provided strong suppression that in the long run cannot be expected to overcome brome. Regardless of their return on investment, they failed to deliver satisfactory brome control (i.e.. >90% so that the seed bank is not dramatically reduced) and are useful only in terms of managing brome within the current crop at best.

• At application the canola was growing well although there were blackleg lesions on the older leaves across both varieties in the paddock which was the reason the 450 mL/ha rate was selected.
• There had been no canola grown in the trial paddock in recent history with the only canola grown on farm back in 2009 in a paddock located ~ 2 km to the North West.
• With both varieties rated as MS or moderately susceptible to Blackleg and given the seasonal conditions with a High blackleg disease risk an application of Prosaro would be beneficial.
• The advantage of using a seed treatment under these conditions can be seen with the Jardee HT treated with Jockey Stayer not having as severe infection early and losing the plant stand. This can be seen in the differences between Prosaro treated Cobbler and untreated with a much bigger yield increase (see attached report).

• Proximal sensing reflectance data predicts soil moisture with reasonable accuracy at depths (0-10, 10-30, 30-90 cm) on upper Eyre Peninsula in 2018.
• Reflectance data may also be useful for predicting the amount of soil nitrogen and crop macronutrients, including but not limited to nitrogen, phosphorus, potassium and sulphur.
• Further experimental data is required to use soil and crop reflectance as a means to predict nutrient content because environmental parameters can confound results.

• Proximal sensing reflectance data predicts soil moisture with reasonable accuracy from samples taken at depths (0-10, 10-30, 30-60, 60-100 cm) across 46 Eyre Peninsula locations.
• Moderate relationships were found between % organic carbon, pH(water) and soil spectral data.
• Reflectance data have been proven useful for predicting the amount of crop macronutrients, including nitrogen, phosphorus, potassium and sulphur.
• Further experimental data is required to test the reliability of the existing predictive models of soil absorbance and crop reflectance as a means to predict nutrient content.

• There was no interaction between variety and treatment in this trial
• Glyphosate treatments were the highest yielding, being comparable with the direct harvested (and nil) treatment.
• In this trial, none of the treatments had an adverse effect on germination.

This trial has run for the past 3 years at the SFS Gnarwarre site. Chick peas have shown consistently good returns. We now have the local knowledge to help grow pulses in this area.

• Sowing depth had no effect on emergence, biomass production or grain yield in lentils and field peas.
• Field peas - Early sowing (early - mid May) beneficial at the Mallee sites for newer varieties (PSL4, Snowpeak and Excell).
• Lentils - Later sowing (mid June - early July) beneficial this year due to late rainfall.

• The use of pulses in the southern regions show some potential- further trial work needs to be done to examine this fit.
• Follow up Sub soil and Deep N tests need to show +/- effect of N in system
• Pulses could be economically viable as a crop, disease and weed break.

The potential advantages of growing pulse crops are well recognised, such as: increasing soil nitrogen,
breaking disease cycles for cereal crops, providing a high nitrogen feed grain and being a cash crop in their
own right. Field peas are well suited to the Central West and other pulses are useful, depending on pH,
drainage and weed control.

Cassab lentils provided the best yield results; howerver, these results weren't consistent due to herbicide drift.

Pulses have a major role to play in the cropping rotation in the high rainfall zone. Many growers are already achieving good results due to sound management and the ability to ensure that operations such as sowing and spraying are done on time. These growers have shown that if done successfully, pulses can form a profitable part of the rotation. In the high rainfall zone they can be high yielding and produce a sound gross margin, as well they provide opportunities for disease breaks and herbicide rotations and the grazing value of some pulse stubbles, such as beans and peas, should not be under estimated

• This trial was initiated at the request of growers, to allow an improved understanding of the effects on yield and germination of different methods of dessication of beans.
• There was no interaction between variety and treatment in this trial.
• Glyphosate treatments were the highest yielding, being comparable with the direct harvested (and nil) treatment.
• In this trial, none of the treatments had an adverse effect on germination. 

• Peas are the most robust pulse option in low rainfall environments, but erosion risks must be well managed.
• Early sowing is essential for maximising pulse yields.
• Kaspa is an option for low rainfall regions, but has generally performed best in the more favourable years.
• No significant yield difference occurred in Kaspa by increasing plant density from 45 to 55 plants/m2 in 2003.
• Beans and chickpeas are opportunity crops only in low rainfall environments and suited to better years and more favourable conditions.

• A range of agronomic and variety trials for pulse crops were sown at sites across the High Rainfall Zone
(HRZ) of the South East in 2018.
• Trials across this zone are part of national breeding program trials (adding varietal information to GRDC
National Variety Trials database) or funded by MFMG.

• A range of agronomic and variety trials for pulse and alternative crops were sown at sites across the High Rainfall Zone (HRZ) of the South East in 2017.
• Trials across this zone are part of national breeding program trials (adding varietal information to GRDC National Variety Trials database) or funded by MFMG.
• Results suggest a variety of pulses and alternative crops may be adapted to the south east. 
• Agronomic treatments applied at Millicent did not alter broad bean performance.
• Trial planning for 2018 is underway.

• A range of pulse agronomic and variety trials were sown across the Medium Rainfall Zone of the South
East in 2018

• New faba bean PBA Bendoc, may be an option for growers in the Medium Rainfall Zone of the South East

• The use of Gaucho®600 on lentil to reduce the occurrence and impact of Alfalfa Mosaic Virus was evaluated at Keith
• Chickpea yields of over 1.0 t/ha were obtained at Sherwood
• At Keith average field pea yields were similar between a May sowing and a July sowing
• Average lupin yields of 2.68 t/ha at Sherwood, show it is a productive pulse option on suitable soil types

 

• A range of pulse agronomic and variety trials were sown across the Medium Rainfall Zone of the South East in 2017.
• Trials across this zone are either part of the GRDC-SARDI Bilateral Agreement, the GRDC National Variety Trials program, or funded by the MFMG.
• Results suggest a range of pulses may be adapted to this region.

• In the dry conditions there was no significant differences between the two pea varieties and no significant difference between the faba bean varieties. The yields for all of the varieties was disappointing and is due in part to the hot dry conditions at flowering but also due to the late sowing of the beans. There are also some indications that a frost may have had some affect on the final yields.
• For further conclusions please see the attached trial report.

After two years of trials it appears that the 30cm row spacing is the better option sowing width for both field peas and faba beans. These results should still be treated with caution however as disease levels were extremely low in both years and 2002 was an extremely dry year.

The 1998 season in the southern mallee of Victoria was characterised by an early break, a dry winter and spring, and severe frosts in October.

• Faba beans appear to be the most promising pulse crop for raised beds in the Geelong area. Field peas have been grown for decades in this district and if varieties with improved standability can be found, they should be a second viable pulse. The present semi-leafless varieties offer a crop architecture that is almost suitable for our requirements. 
• It is suggested that faba beans and field peas be commercially trailed on raised beds in 2000
• For full discussion and comments from 1999 observations, please see the attached trial report.

• Chickpeas were consistently amongst the highest yielding pulses at this site across all soil types and EM39 ranges.
• They produced the highest gross margins on both the deep sand and the mid-slope soils.

• Height to lowest pod was greater in wider rows for beans compared to peas or chickpeas.
• Beans were higher yielding on narrower row spacing.
• Standing stubble did not increase grain yield in any pulse crop trialled.
• Standing stubble improved bean yields only at the wide row spacing.

• In the dry conditions there was no significant differences between the two pea varieties and no significant difference between the faba bean varieties. The yields for all of the varieties was disappointing and is due in part to the hot dry conditions at flowering but also due to the late sowing of the beans. There are also some indications that a frost may have had some affect on the final yields. 
• For further conclusions please see the attached trial report.

• The effect of sowing dates and rates on lentil, field pea and chickpea cultivars was investigated. The only experiment that was harvested was field peas; yields ranged from 0.2 to 0.7t/ha.
• The lentil and chickpea trials were not harvested due to the drought conditions. Similar trials were also conducted at Rupanyup, but were not harvested due to the drought and several frosts.

• Faba beans had the highest grain yield (average 5.7 t/ha Canowindra and 5.8 t/ha Parkes) and produced very high biomass (average 14.9 t/ha Canowindra and 13.6 t/ha Parkes) at both sites. The high biomass indicates a high amount of nitrogen fixed (N-fix samples currently being processed), but the beans also had very high removal in the grain with an average removal of 229 kg N/ha at Canowindra and 262 kg N/ha at Parkes.
• Faba beans out-yielded both canola and wheat at Canowindra and Parkes, even with high N input.
• MurringoA (albus) and PBA BatemanA (narrow-leaf) lupins produced very high biomass at Canowindra (17.6 and 15.6 t/ha respectively), but grain yield was lower than faba beans. Biomass of lupins was lower at the Parkes site (3.0 and 7.9 t/ha for MurringoA and PBA BatemanA respectively) which had intermittent waterlogging. Grain yield followed a similar trend with high yield for MurringoA (4.3 t/ha) and PBA BatemanA (3.4 t/ha) at Canowindra but low yield for MurringoA (0.8 t/ha) and moderate yield for PBA BatemanA (2.6 t/ha) at Parkes.
• The dry matter production from vetch was relatively low at both sites but vetch was cut at an earlier growth stage (before podding) to simulate hay cut timing.
• CBA CaptainA chickpeas had relatively low biomass compared to faba beans at both sites, with moderate grain yield (2.2 and 2.6 t/ha at Canowindra and Parkes respectively). CBA CaptainA chickpeas yielded more than lentils at both sites. Lentils (like MurringoA albus lupins) suffered from waterlogging at Parkes and had low biomass and yield.
• Lupins had the highest seed N content, removing 90% more N than chickpeas (lowest seed N content) per tonne of grain produced.
• An assessment of total nitrogen derived from fixation is being completed on the biomass samples to determine a nitrogen balance of each species at these sites and other sites in the project.

• The site chosen for the trial was a red sandy loam soil with inherent low fertility and an acidic topsoil, pH (CaCl2) 4.5.
• In the lentil trial PBA Hallmark had the highest grain yield (2.6 t/ha), higher than both PBA Highland and PBA Kelpie. There was no difference in peak biomass between any of the varieties.
• Sturt had the highest grain yield in the field pea trial (5.3 t/ha), with PBA Wharton lower yielding (3.9 t/ha). PBA Wharton also had a lower peak biomass (9.9 t/ha), compared to Sturt (12.5t/ha) and PBA Taylor (12.7 t/ha).
• CBA Slasher yielded the highest in the chickpea trial (2.7 t/ha), with both CBA Slasher (5.0 t/ha) and CBA Captain (4.9 t/ha) having higher peak biomass than the kabuli variety PBA Royal.
• There were no differences in yield between varieties in the faba bean variety trial. PBA Samira had the highest peak biomass of the faba bean varieties (9.4 t/ha).
• The Albus lupin variety Luxor was the highest yielding variety in the lupin trial (3.0 t/ha), higher than both Murringo and PBA Bateman.
• There were no differences in yield or biomass between varieties in the vetch trial.

• Four variety screening trials were sown at each site; one in late April, an Early screen including faba beans, vetch and lupins; three further trials were sown in mid-May – Chickpea screen, Field pea screen and Lentil screen.
• In the Early screen, PBA SamiraA grew the most biomass (17.4 and 12.0 t/ha) and had the highest grain yield (5.7 and 5.2 t/ha) at both Caragabal and Ganmain, respectively.
• There were large differences in seed size (grain weight) for faba beans at both sites which is important from a marketing perspective (larger grains generally more desirable) and for use as seed when calculating sowing rate.
• Faba beans yielded more than double the lupin varieties at Caragabal, primarily due to their ability to tolerate intermittent waterlogging.
• At both Ganmain and Caragabal the desi chickpea varieties CBA CaptainA, PBA DrummondA and PBA SlasherA grew more biomass than the kabuli variety PBA RoyalA. The desi varieties also had higher yield than the kabuli variety PBA RoyalA at Caragabal. Grain size of the kabuli PBA RoyalA was approximately 70% larger than the desi varieties.
• There was no difference in grain yield between the four lentil varieties at each location (Caragabal average 1.7 t/ha, Ganmain average 2.0 t/ha). Intermittent waterlogging at Caragabal likely reduced grain yield compared to Ganmain. PBA KelpieA produced larger seed than the three other varieties PBA HallmarkA, PBA HighlandA and GIA LeaderA.
• In the field pea trial, PBA ButlerA and PBA TaylorA (both 3.4 t/ha) yielded more than PBA WhartonA (2.9 t/ha) and PBA PercyA (2.6 t/ha) at Caragabal. There was no yield difference in the field pea trial at Ganmain (average 2.9 t/ha).
• Grain N concentration was generally highest for vetch and lupins; intermediate for faba beans, field peas and lentils and lowest for chickpeas. Calculated N removal (yield × grain N %) was highest for the high yielding faba beans, averaging 235 kg N/ha removed.
• Biomass data is being processed to determine N-fix of each species which will be used to calculate the N balance for each pulse species.

• Wheat and field peas had the highest yields and gross margins compared with lupins and vetch.
• Field peas have the potential to be an alternative crop in western cropping rotations.

• Chickpeas - New ascochyta blight resistant varieties of chickpeas continue to offer great promise, but the 2006 drought severely reduced seed availability for 2007. Large seed production areas are planned for 2007 and large quantities of seed should be available in 2008 of all chickpea varieties listed below.
• Fieldpeas - Varieties Sturt and Bundi (limited seed supply) will be available to growers in 2007. Both provide yield advantages over Kaspa. New early flowering Kaspa type field pea varieties have been identified and will be available to growers by 2009-10.
• Lentils - The 2006 drought has delayed the release of Nipper to growers until 2008. The green lentil Boomer will also be released in 2008 and offers an opportunity for development of a green lentil industry in Victoria.

PBA Striker has a good fit in Mallee rotations, but ascochyta needs to be more carefully managed than with resistant varieties like PBA Slasher and Genesis 090. Early sowing was still beneficial for all pulses, but particularly lentils, despite the dry start. PBA Percy and PBA Gunyah are showing good potential for the Mallee, as is PBA Wharton.

Sea Lake was extremely poor and the vetch was unharvestable. Laura fieldpeas yielded 1.01t/ha, respectable for the season.

Earlier sown beans and lupins proved that pulses can yield in a very dry year. Although yields were comparatively low, an economic analysis has revealed that this enterprise selection was still profitable. Later sowing of peas, chickpeas and lentils showed little benefit due to the lack of follow up rainfall.

• The early maturing pea variety Celine was the highest yielding pulse when compared to beans, chickpeas and lentils.
• Celine peas yielded 2.54t/ha significantly higher than 1.64t/ha for the variety Kaspa. In 2006 at the Inverleigh trial site, peas failed with an average yield of 0.36t/ha, wheras in 2007 an average yield of 3.14t/ha was achieved.
• Bean yield reponses in 2008 were reasonable for the dry finish. Farah beans yielded 1.8t/ha signficantly higher than Nura beans which yielded 1.7t/ha. In the past 2 years beans have yielded an average of 2.25t/ha at the Inverleigh trial site.
• Both chickpeas and lentils failed due to the dry season, with onlyl minor rainfall event occurring during their growing season.

• In 2009, field peas were the only pulse crop to produce measurable yields in the trials run at Condobolin and Euabalong.
• All field pea varieties produced similar yields at Condobolin.
• Harvest was difficult due to stunted plant height and lodging.
• Sowing pulse crops early is essential to maximise yield.

• Five new pulse varieties were released for southern Australia in 2013. It is important to carefully assess the agronomic, disease and marketing strengths and weakness of each variety, and their overall role in the farming system.
• The warm, wet winter favoured biomass production and early botrytis grey mould onset in lentil and faba beans in 2013. Timely canopy closure fungicide application was critical for reducing yield loss in varieties with intermediate resistance.
• Weed competition was a major constraint to pulse production in 2013. A GRDC funded project has successfully developed alternative herbicide tolerances in lentil and faba bean and field validation is expected in 2014.  
• Clethodim resistant ryegrass is becoming a major issue in pulse production and alternative weed control strategies require investigation.

• Harvest was difficult due to stunted plant height and lodging.
• Sowing pulse crops early is essential to maximise yield.

• Yarrum peas have been the highest yielding variety over the past several years.
• PBA Flash is a red lentil that has performed well, probably because it is earlier maturing and springs have often been poor.
• PBA Slasher and Genesis 079 are the highest yielding desi chickpeas, although Genesis 090 also did well at Struan where late rainfall helped.
• Farah beans generally performed well in the South East in 2009 and the hot finish did not suit Nura as it is later flowering than Farah.
• Jenebillup outperformed Mandelup again and small quantities of seed should be available in 2011.

• While KASPA peas did well in 2010, several new varieties show great potential
• PBA Jumbo is a large-seeded red lentil that performed well in 2010.
• PBA Slasher was the highest yielding chickpea in 2010.
• PBA Kareema is a large seeded broad bean that has done well in the lower South-East for several years. 
• Janabillup lupins perform better than Mandelups in 2010.

• Pulses last season were affected by both drought and frosts.
• Prices were exceptional in 2006/07, with high demand and low supply.
• Herbicide residues may influence crop rotations more than diseases in 2007.
• Seed quality and availability will also be a big issue for pulses in 2007.
• Timeliness of sowing is becoming a greater issue with pulses.
• Pulses cut as forage proved to be a worth while option last season .

• Winter habit canola has been successfully sown in spring, grazed over summer and harvested for grain in 2012 and 2013.
• Establishing canola in spring means larger, more resilient plants in autumn with less impact from slugs and waterlogging.
• Forage value comparable to commercially available dedicated forage rapes over summer and autumn with added benefit of oil seed production.
• In 2012, grazing over summer increased grain yield compared with no grazing.  Ungrazed yield was 1.9 t/ ha; grazed was 2.7 t/ha.  Taurus sown at the conventional time (April) yielded 2.3 t/ha.
   

Currently, growers with commercial off-the-shelf (COTS) non-RTK, non-subscription autosteer equipment obtain accuracies of ~0.1m. Our original expectations were that this level of accuracy could not be reliably achieved with any of the tested signals. The level of accuracy initially anticipated from the SBAS signals was 0.5 – 1.0m @95%, significantly worse than available from growers COTS systems. These expectations of the SBAS signal were largely confirmed by the testing completed as part of this project. We believe that the testing results and survey feedback clearly demonstrate that the SBAS signals should not be attempting to compete with or replace COTS systems at the <10cm level.

However, whist the COTS systems are widespread and grower’s accuracy expectations are driven by COTS system performance, they are aimed at high value tasks (harvesting, sowing, spreading) and as a result are expensive and lack flexibility. Based on the testing conducted and survey feedback from growers, we believe that growers will need accuracies of <=20cm for less critical high value tasks (such as spreading ameliorants and spraying chemicals) and >20cm for general tasks. It is these areas that we believe SBAS signals will offer the greatest benefit, primarily in terms of cost, reliability, and flexibility.  

Our thoughts with regards to grower’s accuracy requirements changed over the course of the year. In particular we recognised different levels of accuracy are needed for different tasks (although this is not necessarily recognised by the growers). With increasing adoption of cm-level NRTK technology by growers (particularly in WA) future SBAS signals need to deliver as close as possible to cm-level accuracies. If reliable performance at accuracies of<20cm can be achieved, the reduced costs associated with SBAS may encourage some farmers to compromise on accuracy for high value tasks.

• Early application of foliar zinc at the 2 leaf stage may assist with suppressing initial yellow leaf spot infection but unlikely to be enough to overcome any zinc deficiency in crop as leaf area limits capacity for uptake.
• Stubble management techniques that aid stubble breakdown or removal are effective measures to control incidence of yellow leaf spot in crops sown into stubble.

Grain quality results showed very little variation between all treatments with test weights between 60.8 and 63.6, protein between 13 and 13.9, moisture between 11 and 11.2 and screenings between 7.6% for Jockey and 9% for Dividend © 130 mI/l 00kg.

There was no stripe rust development in this trial and as a result no statistically significant responses to fungicide application in terms of yield or quality.

• Results showed 100% of the ryegrass samples and 22% of the sow thistle samples were resistant or developing resistance to at least one herbicide, with multiple resistance common in ryegrass.
• Growers and advisers were accurate 74% of the time when predicting ryegrass resistance. This reduced to 65% for post emergent herbicides.
• No-till continuous cropping rotations hosted higher resistance levels and often to more herbicides than less intensive rotations including pasture. However, in many cases, samples from paddocks that have had minimal herbicides often showed resistance to multiple herbicides.
• Cross resistance between Logran and Hussar in ryegrass was lower than expected.

The pattern of response to fungicide application, whilst not always significant, revealed a more even weighting of benefits from upfront fungicide versus foliar fungicides for the susceptible variety Mitre, but a trend for greater advantage to foliar fungicide in the moderately susceptible variety Kellalac.

• Winter feed options trial to value add to the MFMG day at Keith.
• Range of winter feed options evaluated under specific local conditions.

Post sowing pre-emergent and early post emergent herbicide applications all reduced radish numbers but not sufficiently to be commercially acceptable. High rates of triazines were more effective in controlling radish and were quite well tolerated by the broadleaf lupins in this trial. For effective control of radish in lupins, a post sowing application of triazine followed by a post emergent application of either Brodal or Eclipse is required.

Post-sowing pre-emergent treatments were not active enough to reduce a large radish population to a commercially acceptable level. Early post emergent treatments were more effective in reducing radish populations to a manageable level but did not eliminate the radish problem. Product mixes containing Brodal were the most effective in controlling to low levels quite a dense radish population.

In 2015 mouse monitoring will continue at all of the regional sites. To further identify mouse population dynamics CWFS will also be in contact with further persons from each region to identify mouse activity perhaps not recorded by monitoring activities. To be involved in mouse monitoring, or if you have any observations or queries, don’t hesitate to call Nick Hill at CWFS on 02 6895 1038 or 0437 612 140.

Weeds external to a cropping area (ie; along fence lines and roadways) are a known problem. They impact negatively upon a cropping operation in a number of ways; ie,

• Pest insects - Weeds can provide refuge for insect pests and act as a point source of distribution into a cropping area.
• Diseases - Weeds can act as a host for crop disease. When an infected weed is fed upon by a pest insect (e.g. aphid) and the pest insect then feeds upon a plant within a cropping zone the disease is transferred to the crop.
• Seed - Weeds external to a cropping zone provide a source of seed that can enter and infest a cropping area.
• Mice - Weeds external to a cropping area provide food, moisture and refuge for mice.
• Herbicide resistance - Weeds external to a cropping area do not generally receive the same levels of control as weeds within a cropping area, which can assist in the development of herbicide resistance.
• Green bridge - Weeds that perpetuate external to a cropping season provide what is termed as a “green-bridge”. This green bridge is known to enable pest insects and diseases to survive as well as provide a source of weed seed for future in-crop infestations.

• In glasshouse trials, which grew normally and produced grain when soil dressings of copper sulphate replied to surface soil from the field sites.
• There is therefore no inherent characteristics of the soils which makes fertiliser copper unavailable for plant uptake.
• The pattern of rainfall at each field site was compared with the rate of development of the wheat. When symptoms of coffered deficiency appeared in negligible grain yields occurred despite fertiliser application no effective rain fell in the 20 days before the plants reach the boot stage of growth.
• When soil dressings improved grain yield effective rainfall occurred within 14 days prior to booting.
• It is postulated that wheat cannot absorb sufficient copper for normal growth and development from a dry fertiliser zone.
• When the zone is dry just before booting wheat suffers an acute deficiency of copper during a critical phase of pollen formation resulting in infertile pollen.

Soil type and topography/drainage will be the major factors that determine the effectiveness of the raised bed system.

• Phillip Adams has been working on raised bed farming for the past seven years and is convinced the system has significant benefits.
• Raised beds increase the quantity of organic matter in the soil which is of great importance in improving soil structure and promoting germination and growth.
• All land is suited to raised beds, however paddocks where excess water is a problem (eg. sodic soils prone to waterlogging) will benefit the most. The aim of raised bed farming is to produce loose soil beds where water can drain off to prevent waterlogging in the root zones, to provide adequate drainage, and to store excess water for use when conditions turn dry.

Please see the attached trial report for results.

The trend to higher grain yield and deeper root growth in the deep rip treatment suggests that in heavier soils deep ripping may be beneficial to encourage deep rooting and deeper infiltration of water following rainfall events. While the observations relate to responses in the year in which the treatments were imposed, it will take further cropping cycles to determine the stability and sustainability of these responses. The pattern of rainfall distribution and the overall soil water dynamics may have also had an impact on the yield responses. While the initial response is promising, further testing would be required before recommendations could be made. 

The first-year response of a shallow cultivation treatment (as bed renovation) was not significant and barley yield was marginally superior in the control.  This is in contrast to the results at Gnarwarre where opposite trends were observed, but on a lighter soil. In the heavier Lismore soils, it may be worth looking at the deep ripping option as the higher rainfall compared to Gnarwarre may result in a different soil water use pattern. The shallow cultivation treatment also should be monitored for a further year or two until the system achieves equilibrium. 

• Raised beds increase productivity on saline, waterlogged land along with fertiliser and fencing our wildlife.
• Potential issues: uneven bed formation can make seeding difficult, saline soil may be brought to the surface, leached salts may cause damage.

• Although there was a very late break to the season, cooler conditions through September and October maintained good yields. Mid to short season varieties performed well, namely EGA-Gregory (at 3.0t/ha), Ventura (at 3.0t/ha) and Strzelecki (3.0t/ha).
• Yield varied from 1.8 - 3.0t/ha.
• The protein levels were all below the Prime Hard receival standards.

• In 2004 the organic system had the lowest wheat yield and the highest screenings.
• The 2004 gross margin showed that the Albrecht, Soil Management Riverina and BioAg systems made a small profit.
• The Conventional, Soil Management Riverina and Organic systems have the best long-term (2000-2004) average gross margins, although they are all negative.

The results are showing up trends and possible differences between treatments, but being a long term trial it may take at least five years before any meaningful data or an accurate assessment of each system can be made.

• Row spacing and seeding rate made no difference to yield when sown on 4 May.
• When sown 24 May, yield decreased with wider row spacing’s, and slightly increased with higher seeding rates.
• The variation in this trial was large due to previous seasons header rows.

• Seed colour change (SCC) is slower to develop on branches compared with primary stems, with the primary stem only contributing ~22% of grain yield.
• Relying solely on SCC on the primary stem can underestimate overall seed development on the plant, negatively affecting seed size, oil concentration and yield potential.
• Windrowing earlier than 40% SCC on the primary stem was shown to reduce yield by up to 36% and oil concentration by 6.5%.
• Results clearly demonstrated the penalties associated with an early windrow timing, before 40–60% SCC on the primary stem, and the benefit of delayed windrow timings related to SCC, with yield optimised at the upper end of current industry guidelines.
• Ideally, SCC should be measured on a whole plant basis, not based solely on the primary stem, as branches contribute a large proportion of grain yield. There is also a further need for a clear definition as to what constitutes actual SCC in order to develop robust industry guidelines around windrow timing.

• 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.

• There are large differences in virulence at the seedling stage in southern NSW (sNSW).
• The variety grown in a region influences timebased changes in virulence.
• Strategic variety choice can affect the existence of virulent pathotypes.

• Heavy infestation of aphids caused significant yield loss to canola in a high rainfall environment.
• The length of cabbage aphids on spikelets at flowering was directly proportional to yield loss.
• The function yield (kg/ha) = -141x + 1114 where x= spike length colonised in cm explained yield loss R2 0.9.
• Aphid colonisation also reduced seed quality: oil content and seed size.

• Economic gains can be made by applying higher than typical replacement P rates on soils with the ability to fix applications of P.
• Highest gross margins are obtained by growing the most suitable variety for your region assuming P nutrition is corrected.

• Liming and spading had a significant effect on soil pH. The untreated plots (no spading and no lime) had a soil pH that declined from 5.5 to 4.3 down the soil profile.   Simply spading the soil, without lime application, lowered the soil pH of the topsoil to because acidic subsoil is mixed with the top soil.  Liming, without spading, has significantly increased pH levels on topsoil to 5.8 but no effect at depth. Liming together with spading has improved the soil pH at depth.
• Due to variability at seeding and weed control the impact of soil amelioration on productivity of the wheat varieties is not conclusive (CV = 16%). Liming (averaged across variety and spading), reduced yield from 3.2 t/ha to 2.9 t/ha (p=0.009, LSD =0.2). Spading treatments affected seeding depth. This resulted in variable and poor emergence in the spaded treatments. Wheat plant  densities established were 85 plants / m2 in the spaded treatment and 105 plants / m2 in the un- spaded treatment.  Brome grass control was not highly effective and variable across the site. These factors will have influenced the large variability in treatment effects. However future cropping across the trial area may indicate the treatment effects.
• Corack and Mace were significantly higher yielding than Emu Rock, however black point is a risk factor for Corack. The other varieties performed similarly.
• Spading treatments were carried out within a short period prior to seeding and plots were not rolled. This will have had a large influence on the variability of grain yield at the site. To improve future trial research liming and spading need to be carried earlier in the year for soil to settle before seeding or roll soil after spading to prevent machinery from sinking in soft soil.

• Frost and heat shock events can cause significant damage to grain crops during flowering and grain filling.
• To reduce the risk of frost or heat events reducing yield, it is advisable to sow different varieties with different maturity lengths right through the sowing window to ensure that not all he wheat sown on hte farm flowers at the same time.
• An alternative practice would be to sow a mix of two different maturity length varieties in the same paddock. 

• 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.

• For the 3 phases of methane measurement reported, methane emission intensity (L CH4/hr/100g ADWG) was significantly lower for lambs on a better quality forage with high metabolisable energy, digestibility and crude protein.
• Feedlotting is an option that gives producers the flexibility to finish lambs when pasture availability is limited or light soils are at risk of erosion.
• Spray-topping cereal crops is a good management strategy for weed control and feed management for livestock, however, livestock productivity gains can be compromised when spray-topped cereals are grazed without offering lambs better quality fodder supplements.

• Benefit cost analysis using the small yield benefit (up to 100kg/ha) found on shallow ironstone areas in this paddock (0-3cm topsoil over ironstone sheet) showed a nil to negative return on investment.
• In 2019, the season was too dry to measure a yield response.
• In 2020, in-season data was collected but the season was dry with a hard finish (0.7t/ha paddock average) and no yield difference was measured. While the Reefinator may increase plant available water capacity, recent seasons have provided very little moisture.
• Yield maps are critical for ongoing monitoring of paddock machinery-scale treatments where soil variability can confound treatment effects.

Key findings

• Yield loss from crown rot ranged from 7.6% in the bread wheat variety LRPB SpitfireA up to 29.1% in the barley variety CommanderA. • Bread wheat variety choice affected yield in the presence of high levels of crown rot infection with nine entries being 0.30 t/ha to 1.33 t/ha higher yielding than the susceptible bread wheat variety EGA GregoryA.

• Grain protein levels varied from 12.0% in MitchA up to 15.8% in the recently released durum variety DBA LillaroiA. Crown rot infection did not affect any grain protein level in any entry.

• Screening levels varied from 2.2% in the barley variety CompassA up to 9.5% in the bread wheat line LPB12-0494.

• Crown rot infection did not affect screening levels in any entry.

Conclusions

Cereal crop and variety choice provided a 7–33% yield benefit over growing the susceptible
bread wheat variety EGA GregoryA under high levels of crown rot infection at Bullarah in
2016. This could have maximised profit in the growing season but will not reduce inoculum
levels for subsequent crops, because all winter cereal varieties are susceptible to crown rot
infection. Winter cereal crop and variety choice is therefore not the sole solution to crown
rot but rather just one element of an integrated management strategy to limit losses from this
disease.
