There was no take-all evident in the second cereal (wheat on wheat) trial and as a consequence no seed treatment differences in yield, however there was evidence of late season leaf rust control in the second wheat trial.

• 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

The variability across the paddock in the level of Take-all and deep soil N were relatively low and the results can be used to devise a management plan. Rhizovonia and Pratylenctus neglectus the results between the site were more variable

Removal of subsoil compaction by deep ripping resulted in a 370 kg/ha (45%) yield benefit with spading giving an additional benefit of 12% (100 kg/ha) and mouldboard ploughing 39% (320 kg/ha) compared with the deep ripping treatment. Higher biomass and increased head density in the cultivation treatments are indicative of improved nutrient access and effcient use of available water through the season. Water use efficiency was 4.9 kg/ha/mm of growing season rainfall for the control treatment compared with 7.1 kg/ha/mm for ripped, 7.6 kg/ha/mm for spaded and 8.9 kg/ha/mm for mouldboard ploughing. Recent research is showing that nutrient availability is improved when top soil is buried by spading or mouldboard 
ploughing because nutrients become concentrated in the rootzone and less suscpetible to soil drying from evaporation, which can be the case when majority of the nutrients are on the soil surface, (Davies et al, 2012).

• Spading has mixed the non-wetting layer of soil in this paddock through the soil profile, resulting in an increase in crop yield in two out of past three years.
• Using the spader to mix lime and dolomite into the subsoil has improved the pH of the soil and increased yield. 
• Wind erosion is a big risk with spading and caused a yield decrease in 2010, the year the spading occurred. 
• Spading also reduces compaction at a similar level to deep ripping by physically breaking down any compacted layers in the top 30cm.
• Soil type is a large factor in the success of a spading operation; careful consideration must be given to this prior to commencing any spading program. 

 

• Spading has buried the non-wetting layer of soil in this paddock, resulting in an increase in crop yield in two of the past three years.
• Using a spader to mix lime and dolomite into the subsoil has improved soil pH soil and increased yield.

• Antas Sub clover (brachycalnium type) grew significantly more than other sub clovers, and more than twice the production of Trikkala (1.735t/ha DM)
• The more biomass you grow, the more nitrogen you fix. Using rules of thumb (25jg/ha N per 1t DM), Antas would fix 92kg/ha of nitrogen cf 43kg/ha N for Trikkala.

Key messages:

• Treating EGA GregoryA seed with Rancona Dimension reduced establishment losses associated with the addition of crown rot inoculum to 7% compared with 26% when no seed treatment was used.
• In this instance, Rancona Dimension did not provide a significant or consistent yield benefit in the presence of high levels of crown rot infection across the 12 trial sites in 2015.
• Growers should not expect Rancona Dimension to provide a significant and consistent reduction in yield loss from crown rot infection when used as a standalone management strategy.
• Growers considering the use of Rancona Dimension should follow the manufacturer’s advice and only consider it as part of an integrated management strategy against crown rot.

Conclusions

Rancona® Dimension is registered in Australia for the suppression of crown rot infection. Rancona® Dimension reduced establishment losses associated with severe early infection, created by the addition of crown rot inoculum to the seed furrow at sowing, to 7% compared to 26% in the absence of a seed treatment. Further research is required to determine if this improvement in establishment is associated with reduced Fusarium seedling blight. It should also be established whether such severe establishment losses are an artefact of the inoculation process used in the trials or occurs naturally in paddocks with high stubble-borne inoculum loads. In a separate larger trial conducted at Tamworth in 2015 in which infected stubble at the surface was the inoculum source Rancona® Dimension did not have a significant impact on the establishment of EGA Gregory compared to the Nil seed treatment (data not presented). Establishment benefits apparent in the 12 trials unfortunately did not translate into any improvement in grain yield. Rancona® Dimension did not provide a significant yield benefit over the use of no seed treatment or the two other commonly used seed treatments examined in this study under high crown rot pressure across 12 sites in 2015.

Although Rancona® Dimension is registered for the suppression of crown rot, with activity against early infection and potential establishment losses evident in this study, growers should not expect this to translate into a significant and consistent reduction in yield loss from crown rot infection when the product is used as a standalone management strategy. Integrated management remains the best strategy to reduce losses to crown rot. Growers may like to consider including Rancona® Dimension (320 mL/100 kg seed) as one additional component in their integrated management of crown rot.

There were significant increases in tissue tests levels where boron and moly had been applied. Plant tissue levels were also significantly lower in phosphorus where 18 kg/ha had been applied versus 25 kg P.

• Both Aramo and Bounty performed as expected in the field in accordance with the label recommendations.
• Conditions at time of spraying and for the rest of the season were not favourable, however, both products stood up and performed quite well when compared to the unsprayed areas.

• On average the wide row lupins yielded 115kg/ha higher than the narrow lupins.
• Simazine damage was very pronounced in this particular crop. However, damage in the wider rows appeared to be much less than that in the narrow rows.
• The same seeding and fertiliser rates were used for both treatments which made changing the bar over relatively quick.

Sumemr fallow efficiencies at these sites were generally found to be within the range of 20 to 30%.

The advantages of kikuyu are:

•  Weaners can be fed in the paddock.
• Sheep can be set stocked for long periods.
• Ground cover is maintained.
• The kikuyu has carried weaners over summer, whereas the annual pasture is carrying wethers.
• There is no evidence of kikuyu movement out of the paddock into adjacent areas of native vegetation.

Averaged over all nitrogen treatments, there was no statistical difference between the 2 different plant populations in terms of yield or quality parameters, however the trends were identical to MacKellar: lower plant population 108 plants/m2 giving slightly lower yield (0.25 tlha) and higher protein.

• 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 was a wide variation in the production performance of the 2010 drop hoggets that was addressed with a 30% culling rate that included a mix of visual and objective measurement.
• We have collected initial measurements from the 2011 drop lambs. Further bodyweight gain over summer and wool quality and quantity in June measurements will be collected after which the wethers and culled ewes will be sold.

Report: Erin Cahill - on-farm results summary: Soil water repellence is relatively easy to diagnose but because numerous soil types can be affected and there are many possible management options deciding how best to address the problem can be difficult. Deciding on a water repellence management strategy in cropping systems will be determined by many factors including: the severity of the water repellence, soil types affected, how much of the farm is affected, impact of other constraints and whether repellence occurs in discrete patches or larger more widespread areas.

• The zinc content of particle size fractions of 12 mainly zinc deficient soils was measuredly extraction with three contrasting extractants.
• The soils, which ranged from sands to a black earth, were from Western Australia and Queensland Particle size fractions were obtained by sieving and sedimentation after ultrasonification of soil suspended in deionized water.
• High clay soils had higher concentrations (mean 54 mg kg-I) of acid extractable –zinc than low clay soils (mean 2 mg kg-I)After fractionation.
• Lowest acid extractable - and DTPA-zinc were found in coarse sand fractions and concentrations increased with decreasing particle size.
• Clay plus silt fractions contained 60-99% of the whole soil acid extractable –zinc.
• The CaCl2-zinc concentrations were very low (<0.5 ug/kg-I) for all soils.
• In whole soils, DTPA-zinc was only a small proportion of the acid extractable-zinc.
• Acid extractable -zinc was correlated with oxalate extractable Fe and with oxalate aluminium whereas DTPA-zinc was correlated with oxalate extractable Fe.The AE- and DTPA-zinc were correlated with organic carbon only in some fractions.
• The DTPA- and CaCl2-zinc were not correlated with acid extractable -zinc content, nor was DPTA-zinc correlated with CaCl2-zinc in whole soils or fractions.

• 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.

Zinc should be applied every three to four years as part of the normal fertiliser program when cropping in the Mallee and Wimmera.

• Grain yields were increased by sowing early (mid-April to early-May) over later sowing (end of May) under the favourable growing seasons experienced at Hart in 2016, in contrast to similar climatic seasons in higher rainfall areas of SA such as Tarlee.
• Varieties with agronomic characteristics of early flowering and high biomass production optimised yields.
• There was no change in grain yields from application of plant growth regulators (PGRs) on early sown faba beans.
• Agronomic traits related to improved harvestability were observed from some PGRs, however further field testing will be required to better understand the best application timings and quantify benefits.

• Prices for faba beans have remained very high compared with long term averages, enhancing the profitability of faba beans. Growers always need to be aware of possible price swings as the international market is limited. The potential return for the crop should be based on longer term pricing between $300 and $400/ t.
• New varieties, PBA Zahra and PBA Samira, offer significantly improved grain yield (>10%) and disease resistance compared with older varieties.
• Sowing early is essential to maximise benefits to the farming system from improved biomass and grain yield to maximise profitability.
• Good disease management is critical to maximise grain yield and quality. Growers are encouraged to carefully plan their strategies, regularly monitor crops and have fungicide purchased in advance, to ensure appropriate timing of application.

• 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.

• Commercial viability has been difficult to demonstrate.
• Field trials demonstrated that the H Senor was able to accurately classify annual ryegrass in several broadleaf crops, including canola, faba bean, lentil and field pea.
• Other grass weeds such as brome grass and wild oats were also correctly identified as grasses in these crops.
• Broad leaf weeds were accurately classified in cereal crops, however this was more difficult due to the overlapping nature of the cereal crops at the time when the broadleaf weeds had emerged.
• Classification accuracy was lower for detection of grass weeds in cereal crops and broadleaf weeds in broadleaf crops, and these scenarios were not pursued for that reason.

• Early sowing, concurrent with previous research, was highest yielding in 2012
• There appear to be several promising new varieties available for southern Victoria, offering a range of grain types and forage options, associated with excellent yield potential.
• Crop topping results highlight the importance for growers and advisors to be aware of both weed and crop growth stages, otherwise significant grain yield loss could occur.

• New varieties are likely to offer significant yield improvement in southern Victoria, along with improvements in disease resistance.

• There were no significant differences in yield between lupin or faba bean varieties.
• Farah was the highest yielding faba bean variety and Mandelup was the highest yielding lupin variety.
• Disease and weeds were a significant problem in these poorly competitive crops in this wet year in Gippsland.

• Commercial viability has been difficult to demonstrate.

• An advanced breeding line (AF07125) has been developed with improved resistance to CLS.
• There was no CLS in the trial, and the fungicide amended fertiliser (Impact-in-furrow) provided no additional benefits in terms of grain yield.
• Disease levels were low, and grain yield was high, averaging 4.3t/ha across the trial.
• The potential release AF07125 was the highest yielding variety, outyielding Farah and Nura by 5%

• Chocolate spot is a major disease in bean crops, causing significant losses to yield and profitability.
• Low disease levels in 2012 and favourable seasonal conditions meant that there was no treatment or variety response for either disease severity or grain yield.

• Crop-topping 7-14 days prior to milky dough stage of ryegrass caused significant yield loss at all three sites, and ranged from 24% at Melton to 72% at Bool Lagoon.
• Crop-topping at the milky dough stage (MDS) of ryegrass caused significant yield loss at only one of the three sites (Bool Lagoon).

• The late break (12 June) and prevailing seasonal conditions were unfavourable for the spread of disease, although chocolate spot and rust did infect the trial plots early in the season. Disease was not a yield limiting factor in this trial this year.
• No significant difference was recorded between any of the different fungicide spray programs within varieties or between varieties.
• Fiesta VF plots had a reduced plant population compared to the other varieties due to poor seed quality of the commercial seed sourced.y treatment.

• Low levels of ascochyta. Fiesta had a significantly higher foliar symptom score (2.1) than
  Farah and Ic*As/7/3 (both 1.1). The Standard and Complete spray treatments reduced
  ascochyta on Fiesta to negligible levels (score of 1.0).

• A low level of rust infection occurred during October and was the only foliar disease affecting bean performance.
• 7% higher grain yields occurred in the fortnightly sprayed (improved rust control) and single
  cercospora treatment (reasons unclear) compared with the nil treatment.
• Grain yields decreased by 14% when sowing date was delayed from May 1 to May 18. No
  further yield loss occurred when sowing date was delayed to June 6.
• Nura was higher yielding than Farah at the mid sowing time and equal at the others, unlike
  in previous trials where Nura has been lower yielding at later sowing dates. Late rainfall events in 2007 were of more benefit to Nura than Farah.
• Necking (collapsing of top part of bean plant) was greater at the early sowing time. Nura
  had a higher level of necking than Farah sown early, but yields were the same. Similar
  necking and yield occurred between the two varieties when sown late.

• Yield of faba beans (ignoring the broad bean PBA Kareema) averaged 1.5t/ha at Wanilla in 2012. Early establishment and growth was excellent, disease pressure was low, and beans showed high yield potential.
• Beans appeared to “hay off” late in the season due to high early season biomass production and the dry and rapid finish to the season, together with the occurrence of several high temperature events during late flowering.

• There was low disease pressure in 2018 and there was no difference in grain yield between the nil control and various fungicide programs. 

• There was low disease pressure in 2018 and there was no difference in grain yield between the nil control and the fungicide programs.  
   

• The three bean varieties, Farah, Fiesta and Nura, gave similar yields and showed a similar yield response to delayed sowing – i.e. around 1.5 t/ha when sown on May 12, falling to around 0.9 t/ha with a June 7 sowing.
• Foliar disease levels (ascochyta) were negligible in Farah and Nura at both sowing times, and very low in late sown Fiesta. The slightly higher, but still low, levels of ascochyta in early sown Fiesta were reduced by fungicide sprays, but this did not produce a yield response.
• Spinnaker herbicide applied at 100 g/ha post-sowing pre-emergence caused no yield depression in any of the varieties at either time of sowing, and showed no effect on total plant height or height to bottom pods at harvest.
• The extreme dry late winter/spring conditions may have limited responses to fungicide spray regimes and Spinnaker in this trial.

• Chocolate spot levels were high in 2009, and accounted for 32% yield loss across varieties
  in untreated plots.
• Nura had higher disease levels and lower grain yield than Fiesta across all treatments in
  2009, but a triple chocolate spot spray strategy was effective in reducing yield loss by 25%
  in both varieties.

• In a year with high rust pressure, fungicide application provided beneficial to all genotypes, even those with a good level of rust resistance.
• Several advanced breeding lines from the northern breeding program show promise, with high yield and large seed size combined with rust and chocolate spot resistance equal to or better than the current northern varieties.

Conclusion:

The high rust pressure and frequent rainfall towards the end of the season was likely responsible for the poor fungicide response in the LF experiment in terms of reducing symptoms and improving yield and seed size. In the HF experiment, mancozeb and
tebuconozole were most effective overall in reducing symptoms and improving yield and seed size. Four of the five fungicides were effective in increasing yield in the HF experiment compared with only one in the LF experiment, indicating the need for repeated sprays when disease pressure is high.

Note that the permit for tebuconazole allows for only three applications of 145 mL/ha in commercial crops.

 

• Adding phosphorus (P) did not significantly increase yield or seed weight in the varieties PBA WardaA and PBA NasmaA.
• PBA NasmaA produced greater yield and seed size than PBA WardaA.

Conclusions:

In this experiment, additional P did not increase yield, however, on a lower P site, a positive response to P might occur. The reduction in yield caused by adding N might be due to reduced nodulation in N-treated plots, although nodulation was not measured in this trial. The greater yield and seed size of PBA NasmaA compared with PBA WardaA supports other experimental data.

• In a year of high disease pressure, most fungicides did not provide a yield and seed size benefit when used at low frequency.
• A high frequency fungicide strategy provided yield benefit using a number of products.
   

• Across four years of trials, PBA Samira and PBA Zahra appear to have consistently shown higher grain yields than older varieties in the Victorian HRZ.
• PBA Bendoc, a new faba bean variety with Group B imidazoline herbicide tolerance, has been released. It was bred from Nura and PBA Samira, has similar flowering time and maturity to these varieties and has yielded similarly to PBA Samira in 2015-2018.
• The breeding line AF11023 is a standout of the new breeding lines for the Victorian HRZ. It has yielded equal to or greater than PBA Samira and PBA Zahra and has a higher level of resistance to chocolate spot than either variety. 

• This study showed that the two herbicide treatments, 2,4-D Amine applied at 250ml/ha and Glyphosate applied at 1L/ha, produced the largest reduction in mature height, but also caused a large yield penalty.

• Visual observations of Spinnaker causing reduced bean growth were quite spectacular.
• The recommended maximum rate of Spinnaker (100 g/ha) suppressed growth and final grain yield in both Farah and Nura, and this was further exacerbated at higher rates and later sowing.
• The results do not show Nura to be more sensitive to Spinnaker than Farah overall, although Nura yields were reduced by Spinnaker at all sowing times, while Farah yields were only reduced at later sowings.

• Soil pH (6.8) at this site was ideal for bean growth, and attempted amelioration through application of lime had no effect on grain yield. In soils with higher acidity beans may still benefit from the application of lime.
• Inoculation of beans is considered to be “cheap insurance” in areas with low previous history or acidic soils prone to water logging. However the addition of inoculum may not always provide a significant yield response, but will generally improve nodulation and consequently N fixation.

Either moly treatments had any increase in yield or nodulation. Tisue tests aso showed increase moly levels but the control was above deficiency threshhold.

No product had significant effects on crop height.

• Trial not harvested due to drought conditions

• All three varieties responded similarly to plant density, with no significant variety by plant density for either curvature or slope between the different varieties.

• All three varieties responded similarly to plant density, with no significant variety by plant density for either curvature or slope between the different varieties.he two varieties when sown late.

• PBA Samira was damaged by Intercept, with damage including stunting, chlorosis and coupled leaves
• Double the rate of standard rhizobia and the new acid tolerant strain improved root nodulation compared to the recommended rate of the standard strain
• Fertiliser rate impacted on lodging only, with standard rate of P standing up  slightly more
• All treatments achieved excellent yields >2.5 t/ha
• PBA Bendoc looked better all year and out yielded PBA Samira for all herbicide treatments

• Plots were too short and not harvest because of the drought.

• Trial not harvested due to drought conditions

A plant population of 25 plants/m2 yielded higher than 15 plants/m2.

7.5 inch rows yielded higher than 15 inch rows.

•Across all varieties tested, there was no significant response to sowing time, which validates the current sowing window recommendation. Therefore, the optimum time to sow faba bean at Lockhart in 2016 was late April–mid May.
• PBA Nasma and Fiesta VF were the two highest yielding commercial varieties.
• The advanced breeding lines AF10089 and AF09169, developed by Pulse Breeding Australia (PBA) were significantly higher yielding than all other varieties.
• PBA Samira and Nura yielded significantly higher when sown on 18 May compared to 28 April.
• Crop lodging was significantly less for the 18 May sowing date.
• PBA Nasma flowered 17 and 14 days earlier than PBA Samira and PBA Zahra at 28 April, and eight and six days earlier at 18 May.

• The optimum time to sow faba beans in southern NSW was late April–mid May.
• Even in a favourable season such as 2016 there was a 10% yield penalty when sowing was delayed from 7 May to 2 June.
• Average seed size reduced by 8% when sown outside the recommended window.
• PBA Nasma, Fiesta VF, and PBA Zahra were the highest yielding commercial varieties.
• Advanced breeding lines AF10089 and AF09169 had significantly higher grain yields, particularly at the 28 April sowing date when compared to other sowing dates.
• Flowering duration for PBA Samira and PBA Zahra was stable across sowing dates, but reduced for PBA Nasma as sowing was delayed.

• Plant height was shorter than normal for the Tarlee area, likely due to the drier than average spring in 2012.
• A plant density x variety response showed that Fiord was the only variety to show decreased plant height with increasing plant density.

• Despite relatively low growing season rainfall in 2012, bean yields were still reasonably high at Bool Lagoon in 2012. It is likely that yields were buoyed by high December 2011 rainfall, lack of disease, and the relatively mild (although dry) finish to the 2012 season.

• Sowing early (April 26) produced the highest grain yields in 2018.
• In a drier than average year there was a yield benefit from very high sowing rates on narrow row spacings, with significant gains from 21 to 31 plants/m2, and from 31 to 45 plants/m2.
• 2018 was a low disease year and there was no disease penalty from higher sowing rates. Yield benefits from higher plant densities should be weighed against higher disease risks in wetter years. 

• The optimum timing to sow faba beans at Junee in 2015 was mid-April.
• PBA Zahra, PBS Samira and PBA Nasma were the highest yielding varieties.
• Commercial yields of 3t/ha are acheivable with appropriate variety and selection management. 

• Th optimum time to sow faba beans at Lockhart in 2015 was mid-Apri.
• PBA NAsma, PBA Samira and Fiesta VF were the highest yielding commercial varieties.
• The 23 April sowing had a mean bottom pod height of 42.3cm, 29% higher than the 13 May sowing.

• Sowing time has far greater consequences on growth, development, dry matter and grain yield of faba bean than variety choice.
• The dry spring combined with temperature constraints, imposed a common ceiling to yield despite large differences measured in dry matter (DM), height and reproductive number across all treatments.
• Early sown faba bean was primarily affected by severe frosts, while later sown was limited by flower node production and heat stress.
• Under these conditions, early April sowings resulted in greater biomass, taller plants, more flowering nodes, additional lodging, more disease and greater frost damage. Given a more favourable spring, disease and lodging could have been further exacerbated, inflicting even greater yield penalties to the first time of sowing (TOS).
•  Findings from this and previous experiments show the optimum sowing window for faba bean on acidic, red brown soils of southern NSW to be from 20 April to 15 May. The later sown crops within this window could still be disadvantaged under early unfavourable finishing conditons.
