Six varieties were sown on 13 May and received three nitrogen rates broadcast on 20 June in front of a 6.5 mm rain event. GoldieA produced the highest yield overall, while increasing nitrogen rate had limited impact on yield but generally reduced grain yield at 90 kg N/ha. Nitrogen affected seed weight and screenings, with test weight remaining not significant across rates (average 52.4 kg/hL).",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research & Report",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/ganmain-2024-new-oat-varieties-vs-nitrogen-rate-response-key-findings/292621/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/ganmain-2024-new-oat-varieties-vs-nitrogen-rate-response-key-findings/292621.png","ImageObject",300,407,{"name":42,"@type":43},"Cart","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-28","2026-09-17",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",15,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"Which oat variety performed best at Ganmain in 2024?","Question",{"text":63,"@type":64},"GoldieA was the standout variety, yielding 0.9 t/ha more than MitikaA when averaged across nitrogen rates.","Answer",{"name":66,"@type":61,"acceptedAnswer":67},"How did increasing nitrogen rate affect grain yield?",{"text":68,"@type":64},"Increasing nitrogen rate had little impact overall, but generally reduced grain yield, especially at 90 kg N/ha compared with 0 or 30 kg N/ha.",{"name":70,"@type":61,"acceptedAnswer":71},"Did nitrogen rate significantly change test weight?",{"text":72,"@type":64},"No. The effect of nitrogen on test weight was not significant, with an average of 52.4 kg/hL across treatments.","https://schema.org",{"og:url":32,"og:type":75,"og:title":10,"og:site_name":45,"og:description":12},"article",{"robots":77,"canonical":32},"index,follow",{"doc_id":79,"site_id":7},292621,1789653250,{"code":4,"msg":82,"data":83},"success",[84,88,92,96,101,106,111,115,120,123,127],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":85,"show_sort_weight":86,"slug":87},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":89,"show_sort_weight":90,"slug":91},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":93,"show_sort_weight":94,"slug":95},"Exam",70,"exam",{"id":97,"doc_module":4,"doc_module_name":25,"category_name":98,"show_sort_weight":99,"slug":100},5,"Comic",60,"comic",{"id":102,"doc_module":4,"doc_module_name":25,"category_name":103,"show_sort_weight":104,"slug":105},6,"Technology",50,"technology",{"id":107,"doc_module":4,"doc_module_name":25,"category_name":108,"show_sort_weight":109,"slug":110},7,"Healthcare",40,"healthcare",{"id":112,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":113,"slug":114},8,30,"research-report",{"id":116,"doc_module":4,"doc_module_name":25,"category_name":117,"show_sort_weight":118,"slug":119},9,"Religion & Spirituality",20,"religion-spirituality",{"id":118,"doc_module":4,"doc_module_name":25,"category_name":121,"show_sort_weight":118,"slug":122},"World Cup","world-cup",{"id":124,"doc_module":4,"doc_module_name":25,"category_name":125,"show_sort_weight":124,"slug":126},10,"Lifestyle","lifestyle",{"id":128,"doc_module":4,"doc_module_name":25,"category_name":129,"show_sort_weight":97,"slug":130},19,"General","general",{"code":4,"msg":82,"data":132},{"doc_id":79,"user_id":133,"nickname":42,"user_avatar":134,"doc_module":4,"category_id":112,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":135,"file_id":136,"file_url":137,"file_type":138,"file_size":139,"view_count":55,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":33,"language":140,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":141,"faqs":142,"seo_title":143,"seo_description":12,"update_tm":80,"read_time":124,"preview_page_count":4},18829141979164,"https://eur-avatar.wpscdn.com/davatar_6f874abed73319feea01a86fa6f0fab8","Do new oat varieties respond to increasing nitrogen rate differently than old varieties?  \nGanmain 2024  \nKey findings  \n• New milling oat varieties show exciting yield potential compared to more commonly grown varieties, MitikaA and KowariA.  \n• GoldieA and KoalaA are taller at maturity than MitikaA and KowariA which may pose a challenge in retained stubble systems using a tine seeder.  \n• Nitrogen management requires further research to optimise both rate  \nand time of application. Although yield was highest with nil N applied it is estimated that 70 kg N/ha would have been removed, mining soil  \nnitrogen.  \nTrial rationale  \nSix oat varieties were sown on 13 May, with three rates of nitrogen applied to each variety on 20 June (broadcast in front of a 6.5 mm rain event) . The season had slightly below average rainfall, with 238 mm from April to October (inclusive), compared with an average 275 mm (Figure 1) .  \nTable 1: Trial site and management details for the oat nitrogen management trial at Ganmain in 2024.  \n\n| Management | 2024 |\n| --- | --- |\n\nSoil type  \nClay loam topsoil with gradual increase in sodicity at depth  \n\n| pH (CaCl2) | 5.8 (0–10 cm) |\n| --- | --- |\n| Soil nitrogen | 15 April: 142 kg N/ha (0–60 cm) |\n| Crop rotation | 2020 wheat, 2021 faba bean, 2022 canola, 2023 wheat |\n| Sowing date | 13 May |\n| Target plant population | 120 plants/m²; sowing rate adjusted for seed size with an average 48 kg/ha |\n| Starter fertiliser | MAP @ 70 kg/ha (phosphorus 21.9%, nitrogen 10%, sulphur 1.5%, calcium 1.6%) |\n| Nitrogen fertiliser | 20 June: urea (46% N) broadcast at Zadoks 13 (3 leaf) growth stage, rates Table 2 |\n\nTable 2: Varieties and nitrogen treatments in oat nitrogen management trial at Ganmain in 2024.  \nTreatment  \nVariety  \nGoldieA MinnieA  \nKoalaAMitikaA  \nKowariAYallaraA  \n\n| Nitrogen rate  (kg N/ha) \u003Cbr>(kg urea/ha) | 0 | 30 | 90 |\n| --- | --- | --- | --- |\n|  | 0 | 65 | 195 |\n\nA Varieties displaying this symbol are protected under the Plant Breeders Rights Act 1994.  \n\n|  |\n| --- |\n| Urea being applied to oats at growth stage Z13 at Ganmain in 2024 |\n\nBrill Ag ♦ 2024 Results ♦ Page 1  \n\n| | 35\u003Cbr>30\u003Cbr>25\u003Cbr>20\u003Cbr>15\u003Cbr>10\u003Cbr>5\u003Cbr>0 | \u003Cbr>Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec | 105\u003Cbr>90\u003Cbr>75\u003Cbr>60\u003Cbr>45\u003Cbr>30\u003Cbr>15\u003Cbr>0 | Rainfa l l ( mm) |\n| --- | --- | --- | --- | --- |\n|  | Month 2024\u003Cbr>Monthly mean minimum temperature  Monthly mean maximum temperature  Monthly rainfall |  |  |  |\n\nFigure 1: Monthly average maximum and minimum temperature, and monthly rainfall at Ganmain trial site in 2024. A frost event of −3.1 °C was recorded on 16 September.  \nResults  \nAveraged across nitrogen (N) rates, GoldieA (4 . 8 t/ha) was the standout variety, with yield 0.9 t/ha more than MitikaA. KoalaA (4 . 6 t/ha) and MinnieA (4 . 5 t/ha) had slightly lower yield but were still well above the more commonly grown KowariA and MitikaA (Figure 2) . Increasing rate of N had little impact, but generally reduced oat grain yield, particularly at 90 kg N/ha. Averaged across varieties, 0 or 30 kg N/ha yielded 4.2 t/ha, dropping to 4.0 t/ha where 90 kg N/ha was applied. The drop in yield was correlated with overall drop in seed weight. Average seed weight (across varieties) was 3.9 g/100 seeds with 0 or 30 kg N/ha, reducing to 3.7 g/100 seeds with 90 kg N/ha applied.  \n\n| | \u003Cbr>\u003Cbr>Goldie Koala Minnie Kowari Mitika Yallara |  |\n| --- | --- | --- |\n| Variety\u003Cbr>l.s.d.
