Seed for seven oat varieties and one grazing barley variety were supplied by Balco. The trial was sown with SARDI small plot equipment on 4 May into moist seed bed conditions (wet to 10 cm only) with 60 kg/ha of DAP fertiliser (18:20:0:0). Seeding rates for every variety were targeted to an establishment of 180 plants/m2. Due to no weeds being present, no pre-emergent herbicides were applied to the trial site.
Plant establishment was counted on 20 June, with dry matter cuts taken on 12 July, 22 August, 31 August and 18 September. Plant height was measured on 18 September. Dry matter samples, simulating hay production, from 18 September (except Durack, 31 August) were dried for 48 hours at 40oC and sent for feed quality analysis using FeedTest. The trial was harvested on 8 November.
The trial was a randomised complete block& |
