Earlier drilling through late February and up to mid-March has been shown to boost yield potential compared to sowings in mid-March to early April (see Chart 1). For example, will the selected variety help to suppress weeds? A series of trials was conducted under dryland conditions, in a Mediterranean-type climate, in order to study the main effects and interactions of sowing date and depth, seed rate and row spacing of wheat and barley. Phone: (03) 5492 2787
spring barley crops grown and frequently monitored at sites in Cork, Carlow and Wexford over three growing seasons from 2011 to 2013. The longer you delay your spring barley drilling date, the greater the opportunity you have to control black-grass with a total herbicide. Westminster, Oxford, GrangeR). This was also a result of the plant reaching maturity very quickly and secondary tillers forming, meaning crops were more exposed to weather (delayed harvest). So how have your crops yielded this year? When sown late, Compass achieved an 0.8t/ha yield advantage, equating to an additional $112t/ha (using Feed 1 price at Dooen of $139.50 from 1 December 2016). Readers are responsible for assessing the relevance and accuracy of the contents of this website. However, the soil was very hard and cloddy at sowing, possibly restricting seed to soil contact, and plant establishment numbers were slightly lower than expected. While this may be good in the short-term, it is important to also think about a varieties long-term impacts on your farm. Tips for winter barley in late autumn: Keep calm and don't panic, but adjust crop management to reflect lost growth . Gross income for Spartacus CL and Scope CL using NVT long-term average yield (t/ha) and Birchip and Manangatang grain prices from 1 December 2016. A combination of factors could have influenced the performance of Compass at most sites: Early sown crops generally grow bigger and taller which, in 2016, contributed to lodging at the grain filling stage and at maturity, resulting in head loss. Although all reasonable care has been taken in producing the reports
Prior to harvest, minor head loss was also an issue but was fairly consistent across all varieties and there was no lodging among varieties. The earlier sown crops were taller and produced substantial biomass. Common problems were dark tipping and ‘bin burn’ which was discolouration that occurred in the paddock due to weather conditions. Spring barley is normally harvested around 3 weeks after winter sown barley Spring barley is in the lower field with a brown (set aside ) border. On high-clay soils, spring barley establishment can vary from 55% for Wheat, barley, and oat were sown at 120, 200, and 280 seeds/m2 (about 44, 72 and 100 lbs/A) in a split plot design with NT and CT as main plots and sowing rate x cereal species combinations as subplots. Wimmera NVT barley grain yield (% of site mean) comparing to 2016 long-term averages (2012-2016) of 22 varieties at Horsham, Brim, Minyip and Kaniva. In this instance, grain discolouration has been disregarded. cost or expense incurred from relying on the information within. Conversely, Compass suffered significant yield loss when sown early. On a yearly basis, new barley varieties are released promising bigger and better yields and improved agronomic traits. In terms of when to sow a variety, previous research has shown that sowing earlier usually results in a yield benefit. characteristics (Table 3). The February-drilled crop had the longest straw, the lowest grain nitrogen and experienced the most brackling. The photo on the left, taken on the 18th April, illustrates the difference in emergence between the March and April drilling date. The easiest win following spring barley is winter barley – the volunteers unless really thick are not really an issue and there is plenty of time to get the land cultivated and the winter barley established for the end of September. Issues encountered with all barley trials this year, were similar to grower experiences. The exceptional year saw a range of varieties with different maturities topping the yields across the multiple Mallee NVT sites. Lodging was prevalent at this site with Compass and Scope CL most affected. Head loss counts were undertaken to gauge the level of head loss amongst varieties, in particular Compass and Scope CL (Figure 1). Applying lime and correcting soil pH to 6.5 is an essential and often forgotten duty when establishing a spring barley crop. When looking at sowing time in the Wimmera, an increase in gross income could be achieved when altering the sowing date for some varieties. A comparison of the gross income from the two Clearfield varieties is presented in Table 4. In 2016 there were a lot of earlier sown crops that, due to excellent growing conditions, produced substantial biomass resulting in severe lodging during the grain filling period and at maturity. This stage can be broken by some kind of 'significant event' such as flooding or where land has been held at field capacity for several weeks (does that ring any bells this year?) Spartacus CL also achieved malt specification but as it is currently undergoing malt accreditation, was classified as feed. Spot form of net blotch was quite evident at the site and was managed accordingly so as not to affect overall yield. Fathom, Rosalind, La Trobe and Hindmarsh are also among the top six yielding varieties (Figure 3). Test weight was slightly lower in most varieties, with the only malt varieties within specification (>65kg/hl) being La Trobe, Scope CL, GrangeR, Oxford and Flinders. Drilling date is vital in getting spring barley off to the best possible start and has a major influence on final yield. For the purpose of this article, malt and feed grades have been determined based purely on Another risk comes from purely chasing yield. When looking at their five year average, yield performance is much lower for these varieties. Figure 2 compares the 2016 average of all Mallee sites (as a percentage of the site mean) with a long-term (five years) average of each variety. “Unlike spring barley, you don’t need to wait for the ground to warm-up for wheat,” he added. Table 2. Can we support your event? Again, it is important to consider the long-term performance of a variety over a number of years and seasonal finishes, and not to throw a variety out on the back of an exceptionally rare year. Nitrogen applications for spring barley in England can normally be 50% applied at growth stage 11 and the remaining 50% applied 10 to 14 days later. The earlier sown crops were taller and produced substantial biomass. The highest yielding varieties at both sowing times were Rosalind and Fathom. Mallee NVT barley grain yield (% of site mean) comparing 2016 to long-term averages (2012-2016) of 18 varieties at Manangatang, Rainbow, Murrayville, Birchip, Hopetoun, Ultima and Walpeup. When sown later, it was one of the top performers with little to no lodging observed. Barley time of sowing and depth Key findings LaTrobe, GrangeR, and Skipper had reduced emergence from deeper sowing under both dry and wet sowing conditions. In order to spread risk, consider growing varieties with different susceptibilities to certain In terms of grain quality, the only malt/food varieties to make malt grade were Westminster and Hindmarsh (food). Table 1. Both the early and later sown plots emerged well and were even across varieties. Assessments included, establishment counts/scores, NDVI (measure of canopy greenness) and grain yield and quality parameters. When is your cut off date for drilling spring wheat/ barley? Figure 1. Both sowing times however, were within malt thresholds. grain quality parameters (test weight, protein, retention and screenings). Barley yields (t/ha) at Kalkee when sown early (TOS1) and late (TOS2). Further information on head loss and lodging susceptibility, and harvest risks in varieties, can be found in the ‘Delayed harvest of barley’ article page 49. A question most growers would be asking is why did Compass perform so poorly? There were also no differences when just comparing barley (mean of all varieties) at TOS1 and TOS2. Generally the earlier a crop is sown the longer its phyllochron will be. Generally, Fathom, Rosalind, Spartacus CL and Oxford performed well across most of the sites. The initial yield results were interesting, with no significant difference in performance for both 2017 and 2018. International: +61 3 5492 2787. Products may be identified by
Before then, conditions did not favour the rapid spread of mildew. Spring barley is an important food, feed and technical grain crop. Oxford, GrangeR and SY Rattler, which are all longer season varieties suited to higher rainfall areas, capitalised on the exceptional finish to the season. Compass performed poorly when sown early, with substantial lodging and head loss. Spring sown cereals, especially barley, are an option if you have a situation where winter sowing wasn’t possible. Throughout the season, Compass suffered severe lodging. Late June: 1000-1500ft: Surface : Spring barley fields will appear as light green colour. Longer season varieties yielded higher than their long-term average in 2016 (eg. 15.10.19. Both the early and later sown plots emerged well and were even across varieties. The variety didn’t appear to favour or capitalise on the above average rainfall and soft finish to the season like other varieties did. Important updates and advice regarding coronavirus (Covid-19), Spring barley drilling dates and yield performance, The initial yield results were interesting, with no significant difference in performance for both 2017 and 2018. Lee. Whilst sowing ideally should take place before mid-march, wait until conditions are right for cultivation. Believe it or not there is a wheat crop in the left side, sitting under 1,000 black-grass heads/m2. Spartacus CL, La Trobe and Hindmarsh had high test weights (within malt specifications). The potential yield will gradually decline and harvesting will be later if sowing is later than this. Later sowing of these varieties, reduced the extent of lodging. to 5°C for spring barley and 8°C for maize, whereas the total number of heat units needed to bring plant to maturity (PHU_PLT) was set to 1 230 for spring barley and 1 200 for maize. One of the poorer performers this year was Compass (particularly in the Mallee). Information on this website is not a scientific journal and has been prepared solely as a means of disseminating information to the members of BCG and the community. Agronomically similar varieties Spartacus CL, Hindmarsh, Rosalind and La Trobe all yielded similar. Sowing at 20 cm, instead of at a 5-cm depth, reduced plant establishment and grain yield by 76 and 62% respectively for barley, and 71 and 39% for wheat. These issues, and the above average rainfall in spring, led to the deterioration of crops (lodging and brackling) and discolouration of the grain which pushed barley outside of malt specifications. 7Q 5.2 Methods and materials ..... -4 5.3 Results ..... "7 5.4 Discussion ..... o? If you were able to drill spring barley in February in good conditions, that is fine. Spartacus CL and Fathom were slightly lower yielding than expected (below the site mean). Rosalind, Compass, Hindmarsh, La Trobe, Spartacus CL and Fathom are still the most consistent performing varieties over a five year average (Note: there is only three years of data available for Spartacus CL and Rosalind). However, different varieties performed better when sown at specific sowing times. Mutti, Jasveer Singh (1995). Cookies used for the essential operation of the site have already been set. The 2016 growing season was exceptional, described by a number of farmers as “the best they have ever experienced”. At Ultima the barley variety trial was sown into a moist soil bed on pea stubble and emerged eight days later. For late-sown crops, plant Assuming Scope CL achieved malt, there really is no difference between gross income of the two varieties. Your email address will not be published.
