2020 HYBRID SORGHUM PERFORMANCE REPORT – NORTHERN REGION 3

This is the second hybrid sorghum performance report published by the Grains Research and Development Corporation (GRDC), following requests from growers to include sorghum as part of the National Variety Trial (NVT) testing program. This guide draws on the information obtained from numerous sources following the first three seasons of trialling, beginning in 2017-18 and continuing in 2018-19 and 2019-20. The aim of the sorghum NVT testing program is to provide growers with independant information that will allow them to make informed choices when deciding on which grain sorghum hybrid to sow in their paddocks.

GRDC acknowledges that an ongoing project of this type would not be possible without the cooperation of growers who are prepared to contribute sites and who often assist with the management of trials on their property.

For all the information on the released sorghum hybrids tested in the NVT program conducted in New South Wales, Queensland and Western Australia, visit the NVT website (www .nvtonline .com .au).

Sorghum was first grown in 1938, with sorghum hybrids becoming available in 1962. The hybrids quickly gained grower acceptance and sorghum is now the dominant summer crop in GRDC’s northern region. It has been traditionally used by the domestic livestock industries (cattle, pork and poultry), while more recently there has been an increasing interest in the grain being used for ethanol production and human consumption (as a gluten-free grain and as a spirit). The five-year average to 2018-19 of the area sown and associated production figures from the Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES), Australian Crop Report (June 2020) appear in Table 1.

Key points

■ This publication covers three seasons – 2017-18, 2018-19 and 2019-20 – of the sorghum NVT testing program

■ The performance values (variation from the mean) that appear in Appendix 1 are from three seasons and this should be taken into context . These values may not be representative of the long-term seasonal conditions experienced by growers in their individual situations

■ The past three seasons have seen extreme conditions, dominated by extensive drought

■ The lack of pre-season and in-crop rainfall resulted in reduced soil moisture profiles, which directly affected trial numbers and, overall, produced less-than-average grain yields

■ When choosing a grain sorghum hybrid, do not rely on the results from a single trial conducted at one location in only one year

■ Successful sorghum production is a combination of good agronomic practices and the best hybrids available for your conditions

■ Know your paddocks, measure the amount of available subsoil moisture and test for nutrition status and soil-borne disease levels

■ Select at least two hybrids that meet your requirements to reduce overall risk

■ Get timing right for every operation: sowing, spraying, desiccation and harvest

■ An even plant population across the paddock and along rows is crucial

The sorghum NVT program began in July 2017 and encompassed four trialling regions and seven production zones. Following support from growers the program has continued, capturing the 2018-19 and 2019-20 summer cropping seasons. The regions were expanded in the second year to include Kununurra in Western Australia. The resultant five regions are Central Queensland, Southern Queensland, Northern NSW, Liverpool Plains and Kununurra.

Season overview

This guide covers three summer cropping seasons: 2017-18, 2018-19 and 2019-20. The climatic conditions experienced leading up to and during the growing periods varied greatly between and within the five trial regions and between the three growing seasons.

The 2017-18 season began with variable rainfall, which required some sites to be relocated and caused others to struggle. Cold conditions soon after sowing slowed growth, but temperatures increased to well above average in late December and January. The increased temperature and low rainfall caused some trials to be abandone,d and others failed to achieve their target grain yield. Of the 21 trials planned in 2017-18, 16 fulfilled the NVT testing program criteria and were deemed suitable to be included in the multi-environment analysis (Table 3).

Suitable trial sites were difficult to find for the 2018-19 season, yet 19 of the proposed 22 sites were established. Some sites

These regions are then split into eight production zones: Central Queensland North, Central Queensland South, Southern Queensland East, Southern Queensland West, Northern NSW East, Northern NSW West, Liverpool Plains and the Ord (Table 2).

Sixty-five experiments were envisaged over the three seasons, but some trials were discarded as they were not sown or did not meet the rigorous standards set by the NVT protocol.

experienced good in-crop rainfall while others were drought stressed, suffered hail damage or were compromised due to uneven run-off from high-intensity storms. From the 2018-19 trial program, 11 sites were deemed suitable for inclusion in the trial series (Table 3).

Drought conditions continued in the lead-up to the 2019-20 season, resulting in low levels of subsoil moisture. To meet NVT protocols, seven of the 22 sites were sown even though, at the time, they had insufficient subsoil moisture. Variable rain occurred during summer with some useful falls in January and February. Resulting grain yields were surprisingly good given the prevailing conditions. From the 2019-20 trial program, six sites were deemed suitable for inclusion in the trial series (Table 3).

Information relevant to a specific trial site can be accessed from the NVT website (www .nvtonline .com .au).



Trial attrition. Individual trials can be excluded from the final NVT database due to either statistical or agronomic reasons. If there is no genetic variance, that is, the grain yields of individual hybrids in a trial do not differ significantly, the trial will not be included in any further analysis. An audit has been carried out on trials grown in the regions over the past three seasons. Auditors were required to score more than 25 parameters and determine if an individual site met the stringent requirements of NVT.

Trials were deemed unsuitable for inclusion on an agronomic basis for any of the following reasons:

■ variable biomass across the site;

■ uneven establishment across the site or along a row;

■ presence of disease, animal or insect damage; or

■ presence of weeds at population levels that would affect grain yield.

* Environment refers to the unique combination of year and location.

Trial sites also had to be representative of their region and trial sowing times needed to match those of surrounding crops.

In 2019-20 the severe drought meant that only seven trials were sown; one of these trials was abandoned due to bird damage, resulting in six trials deemed as acceptable to be included in the NVT multi-environment analysis.

Trial sites. Each production zone aims to have three to four trial sites with a single time of sowing. Each trial site should:

■ ideally have a soil moisture profile greater than 80 per cent of field capacity with no less than one metre of wet soil;

■ have come out of long fallow from winter cereal; and

■ have a soil type representative of the zone.

Row spacings follow industry standards. Successful trial sites within each production zone in each season appear in Table 3.

Number of hybrids in each trial. Breeding companies submit hybrids for inclusion in the NVT sorghum trials that are suitable for the environments under evaluation. Grain sorghum hybrids were submitted by the following companies: Barenbrug, Elders, Heritage, Nuseed, Pacific Seeds, Pioneer Hi-Bred Aust Pty Ltd, Radicle Seeds and S&W Seed Company.

The performance reporting criteria require that lines must appear in two years of testing. Heritage Seeds changed its name to Barenbrug in October 2019, and Barenbrug and Nuseed entered into a collaborative agreement for sorghum from July 2020. The total number of unique hybrids tested was 46; the number tested varied, depending on trial location, from 24 to 32 in the trials conducted in Queensland and New South Wales. Eleven hybrids were included in the Western Australian trial.

Traits investigated. Several traits are assessed within trials including grain yield (tonnes per hectare), screenings (per cent <2 millimetres) and hectolitre weight (kilograms per hectolitre). If an NVT trial is sown at a specific location, the resulting combination of year and location is called an environment. There have been 33 environments analysed for grain yield, 26 for screenings and 27 for hectolitre weight.

Service providers. The trials were managed by four service providers: New South Wales Department of Primary Industries, Kalyx, Eurofins Agroscience Services and Living Farm.

Statistical support. The design, analysis and interpretation of results were managed by GRDC’s Statistics for the Australian Grains Industry (SAGI) project team. Over the three summer cropping seasons that were sampled, a combined analysis of environments (year by location combinations) was completed.

Grain yield. Following harvest, trial grain yields are converted to tonnes per hectare (t/ha) and adjusted for grain moisture. Predicted grain yield values for selected sorghum hybrids from trials conducted over the summer growing seasons 2017-18, 2018-19 and 2019-20 are reported in Appendix 1.

Grain quality. Results for screening (per cent <2mm) appear in Appendix 2 and hectolitre weight (kg/hL) in Appendix 3. The range in both these parameters obtained for individual hybrids across environments demonstrates the difficult seasons growers have experienced.

Interpreting results. Better outcomes are achieved when decisions are based on good information. The information presented in this publication comes from the past three seasons and has undergone a rigorous auditing process and statistical analysis.

The results represent the environmental conditions experienced but may not be typical of a given region. A grower must decide the relevance of the three testing seasons compared with the long-term seasonal conditions that might be experienced before selecting any variety to sow. The predictive value of this guide will improve as more trials and years are added to the sorghum NVT database.

When assessing a hybrid’s performance, it is imperative to consider the seasonal effects and make particular note of the number of comparisons for each hybrid. Growers are best equipped to interpret these results in relation to rainfall (timing, amount and intensity), temperature (extremes and the length of each event) and local environmental factors that affect a plant’s development. As well as the predicted grain yield values that appear in Appendix 1, more detailed information can be accessed from the NVT website (www .nvtonline .com .au).

More information. The full set of parameters that were recorded appear on the NVT website (www .nvtonline .com .au).

Management Growers face numerous decisions before sowing, and getting each decision correct is important as it will ultimately affect final grain yield and farm profitability. Put simply, the best approach is to know your paddock, know your sybrids and get your timing right..

Select paddocks on your farm that meet the requirements of a sorghum crop and fit into the rotations in your farming system. As with any crop, the timing of all operations is essential to success. Monitor the paddock and ensure it remains weed-free during the lead-in fallow to maximise stored soil moisture. Aim to achieve a grain protein between 9 per cent and 10 per cent to maximise grain yield.

MaturitySoil temperature has an impact on the time taken for sorghum to emerge and needs to be checked as the sowing date approaches. As a rule of thumb, when soil temperatures at sowing depth (approximately 5 centimetres), taken at 0800 Australian Eastern Standard Time (AEST), are 16°C and rising for at least five days, sowing can begin. Sowing date needs to be a compromise that helps combat heat stress during flowering (late December/early January), the possibility of ergot if temperatures fall below 13°C (from late sowings) and frost affecting seedling emergence (early sowings).

Most sorghum hybrids fall into one of the following maturity types: slow, medium/long, medium/slow, medium, medium/quick and quick (see Table 4). The time from sowing to 50 per cent flowering varies between these broad categories and is also influenced by temperature. There may be 7 to 10 days difference in the time to reach flowering for the same hybrid sown in spring and in summer.

For example, if it is cost-effective to control two midges/head in a rating 1 hybrid, then cost-effective control in a rating 7 hybrid occurs when there are 14 midges/head. For more information regarding midge resistance ratings contact Tracey Shatte ([email protected]).

Row spacing, plant populations and grain yieldSuggested row spacings based on target grain yield are set out in Table 5. Wider rows are best suited to lower yielding environments. Uneven crop density, poor plant establishment and weed competition are factors that will result in less-than-optimum grain yields in any year.

An even plant stand is essential, and the final established plant population allows for the maximum use of available subsoil moisture. Aim to consistently achieve five to six plants per square metre for good conditions and seasonal outlook; while this population can be reduced to three plants/m² for a conservative target and seasonal outlook.

LodgingLodging can be a problem in all dryland growing areas. Select hybrids with good lodging resistance, especially where moisture stress is likely during the latter stages of grain fill. Crops that remain green and have access to available soil moisture during grain fill are generally less prone to lodging. Moisture stress is the most common cause of lodging. Moisture stress also predisposes the crop to infection and rapid colonisation by Fusarium and charcoal stem rots. These are also associated with lodging, leading to plant death and significant yield loss.

DiseasesMajor diseases of sorghum are Charcoal rot, caused by Macrophomina phaseolina, and Fusarium stalk rot, caused by two species of Fusarium. Both diseases can cause lodging, plant death and potentially significant yield losses.

Ergot in sorghum is caused by a fungus Claviceps africana and can occur at temperatures around 13°C and in high humidity. Therefore, it is a good idea to avoid late-season sowings. Infected crops can suffer yield reduction and the ergot honeydew can cause headers to block up, requiring substantial time to clean down.

All diseases pose a significant threat to the Australian grains industry. Growers should monitor all crops and any suspicious lesions should be collected. Keep samples dry, do not wrap in plastic and contact your local Department of Primary Industries representative or agricultural consultant.

Nutrition Soil tests should be conducted well before sowing in potential sorghum paddocks to ascertain levels of the major elements, especially nitrogen (N), phosphorus (P) and sulfur (S), as well as the minor element Zinc (Zn). Inadequate levels of the minor elements can affect uptake of the major elements, especially N, which will lower the potential yield of a crop. Apply N either pre-plant, at sowing or using a split application prior to and at sowing.

WeedsFor effective control of most weeds, apply atrazine at one of pre-sowing, sowing or immediately following sowing. Apply metolachlor products as a pre-emergent spray for grass control, especially liverseed grass. Seed should be treated with Concep®II seed safener when using S-metolachlor products.

Some hybrids have a phytotoxic reaction to organophosphate (OP) insecticides. This causes symptoms from spotting to intense purpling of leaves and stems. When crops are likely to be sprayed with OP insecticides, it is a good idea to grow tolerant hybrids. Growers should consult relevant seed companies for the latest information on the reaction of hybrids.

DesiccationDesiccation is the use of a knock-down herbicide at physiological maturity; that is, when 95 per cent of the grain, two-thirds down the southern side of representative heads in the crop, have formed a ‘black layer’. Applying the herbicide before appearance of the ‘black layer’ will result in loss of grain yield, lower test weight and small grain. Harvest should occur around 10 to 14 days after desiccation to prevent losses due to inclement weather and lodging, which can be exacerbated by Fusarium infection of the dying plant.

InsectsWireworms. Both false and true wireworms affect the crop by reducing overall plant populations. Press wheels and seed treated with a registered insecticide help reduce wireworm numbers and therefore the amount of damage.

Heliothis. Heliothis larvae feed on developing grain and need to be controlled when threshold levels are reached. Check the crop either early in the morning or late afternoon at regular intervals of three to four days. Nuclear polyhedrosis virus application has proven successful and helps to reduce the potential of resistance to pyrethroids and organophosphates developing in the heliothis population.

Rutherglen bug. Rutherglen bug numbers can increase rapidly from flowering to soft dough. Therefore, aim to prevent large numbers of nymphs developing and affecting the maturing grain. Monitor using the same method as that for heliothis.

Midge. Check the midge rating (Table 4) when choosing which hybrid to sow, especially if you are nearing the end of the recommended sowing window. A midge rating greater than 4 is recommended. Newly released hybrids are tested by the Industry Testing Group, comprising Department of Agriculture and Fisheries (DAF) Queensland and seed companies, for their midge resistance. Inspect crops about three hours after sunrise during flowering. Control of midge will vary depending on the hybrid’s midge rating and the plant population.


Root lesion nematodes Sorghum hybrids are susceptible to root lesion nematode Pratylenchus neglectus and resistant to Pratylenchus thornei. Test your soil by using the PREDICTA® B testing service to determine the species and population densities of nematodes present well before sowing.

PREDICTA® B testing serviceGrowers are faced with numerous decisions before sowing, and knowing the disease status of a paddock helps to determine which crop and variety to sow. Guessing a paddock’s disease status is dangerous and whenever possible growers should avail themselves of the PREDICTA® B soil-testing service. PREDICTA® B quantifies the level of inoculum of several soil-borne pathogens that are common to paddocks in the northern region. The service can be accessed at the PREDICTA® B website (https://pir .sa .gov .au/research/services/molecular_diagnostics/predicta_b).

The performance values (variation from the mean) that appear in Appendix 1 are from three seasons. There were limited trial sites in some regions in some years, so the values should be viewed in context. These values may not be representative of the long-term seasonal conditions experienced by growers in the selected regions.

The values in the tables are the predicted yield t/ha (variation from the mean) relative to the environment mean yield (EMY). Positive values indicate that the hybrid performs above the

mean yield in the environment (year–location combination) cited. Negative values indicate that the hybrid performs below the mean yield in the environment cited.

For clarity, the standard errors are not presented in this report but can be found in the long-term reports at www .nvtonline .com .au.
