title: Optimising Plant Establishment 2021 Inverleigh Canola Experiment

description: Data from the 2021 crop establishment trial at Inverleigh, VIC. The trial compared the establishment of SF Ignite TT canola at different densities, under a conventional seeder (Vaderstad Rapid) and under a precision seeder (Vaderstad Tempo). The experiment was run under the UOA1803-009RTX GRDC research project led by the University of Adelaide, with the experimental trial and local data collection managed by Southern Farming Systems (SFS).<strong>Files:</strong>2021 SFS canola trial.xlsx<strong>Experiment setup:</strong>Experiment managed by Southern Farming Systems (SFS). The trial was organised as a randomised complete block design with 4 treatments (conventional seeder vs precision seeder, and target densities 25 and 50 plants/m2), arranged spatially in a single column with 16 rows, 4 replicates, so 16 plots total. The variety of canola sown was SF Ignite TT.<strong>Variables recorded:</strong>establishment count (plants/m2), seedling depth (mm), interplant distance (cm), peak biomass (t/ha), harvest biomass (g), harvest index, yield (kg/plot), corrected yield at 8% moisture (t/ha), protein (%), oil (%), test weight (kg/hL), 1000-grain weight (g)<strong>Data collection and assessment:</strong>The paddock was sown on 24/04/2021. Emergence counts were made for the first block plots on 12/05/2021, 18/05/2021, 24/05/2021 and 02/06/2021. Seedling depth was recorded for all plots and averaged across 5 counts per plot, measuring from the seed to the soil surface. Interplant distances were assessed and recorded in cm for each plot. Peak biomass and harvest final biomass were measured across three samples taken at each plot. At harvest the yield was recorded in kg/plot and also corrected to 8% moisture content (in t/ha), and the protein and oil content were assessed. The 1000-grain weight was also recorded.

title: Optimising Plant Establishment 2021 Roseworthy Canola Uniformity Experiment

description: Data from the 2021 crop establishment trial at Roseworthy, SA. The trial compared the establishment of canola using a mixture of dead and viable seeds, with the aim of seeing if such seed mixtures used with a precision planter could achieve a similar level of unevenness in the establishment as when using conventional/cone seeders. The experiment was run under the UOA1803-009RTX GRDC research project led and managed by the University of Adelaide.<strong>Files:</strong>2021 Roseworthy canola uniformity.xlsx<strong>Experiment setup:</strong>The trial was organised as a randomised complete block design with 4 treatments (10%, 25%, 50% and 100% viable canola seed), arranged spatially in two columns of three replicates each, for a total of 24 plots.

title: Optimising Plant Establishment 2021 Roseworthy Canola Weed Competition Experiment

description: Data from the 2021 crop establishment trial at Roseworthy, SA. The trial aimed to examine weed competition on canola establishment when the canola was sown at different target densities, under a conventional cone seeder and under a precision seeder. The experiment was run under the UOA1803-009RTX GRDC research project led and managed by the University of Adelaide.<strong>Files:</strong>2021 Roseworthy canola.xlsx<strong>Experiment setup:</strong>The trial was organised as a randomised complete block design with 24 treatments (factorial combinations of: cone vs precision seeder, target density (10, 20, 40, 50 plants/m2), and three densities of sown competitional ryegrass/barley (Nil, 100 and 200)), arranged spatially in two columns containing 2 replicates each, for a total of 96 plots. The establishment of the weeds (rygrass/barley) was very poor however, and there was essentially no weed competition throughout the trial.<strong>Variables recorded:</strong>establishment count (plants/m2), interplant distance (cm), NDVI, bird damage (m), yield (t/ha), 500-seed weight, seeds/m2<strong>Data collection and assessment:</strong>The paddock was sown on 31/05/2021, with competitional annual ryegrass sown on 01/06/2021. However, the ryegrass germination appeared to have failed by 22/06/2021, so barley was sown instead. On 28/06/2021 plant establishment counts for the canola crop were taken across 2 rows x 3 metres, with plant emergence counts made on a third row on 08/07/2021. Interplant distances were also measured on 08/07/2021. By 08/07/2021 the barley seed had not germinated yet, so barley was resown in the plots on 13/07/2021. NDVI measurements were made 4 separate times, on 05/08/2021, 12/08/2021, 19/08/2021 and 24/08/2021. On 24/11/2021 visual assessment was made of bird damage within the plots, assessed as an estimated length (in metres) of the plot that was affected. At harvest on 02/12/2021 the grain yield (t/ha) and 500-seed weight were measured.
