Optimising Plant Establishment 2021 Merredin Canola Experiment

Data from the 2021 canola seeding trial at Merredin, WA. The trial compared the establishment of canola with ryegrass competition across different densities (5 densities for canola vs 3 densities for ryegrass), and under a cone seeder vs under a Monosem precision seeder. The experiment was run under the UOA1803-009RTX GRDC research project led by the University of Adelaide, and the experiment trial and data collection were managed locally in Merredin by the Western Australian No-Tillage Farmers Association (WANTFA).Files:2021 Merredin canola.xlsxExperiment setup:Experiment managed locally by the Western Australian No-Tillage Farmers Association (WANTFA). The trial was organised as a split split plot with 5 densities of canola (10, 15, 20, 30 and 40 target plants/m2), three densities of competitional ryegrass (nil, low and moderate) and two different seeders used (conventional cone seeder vs Monosem precision seeder). The design was embedded in a spatial grid with 30 rows (not including two bordering buffer plots on either side), and 3 replicate columns, for 90 plots total.Variables recorded:establishment count (canola and ryegrass plants/m2), interplant distance (cm), canola biomass (t/ha), ryegrass biomass (t/ha), canola yield (t/ha), protein (%), moisture (%), oil (%), temperature (degrees Celsius), ryegrass tiller countsData collection and assessment:Date of harvest was recorded as 08/09/2021. Plant counts were made for both the canola crop and ryegrass, with 3 counts made per plot on 04/07/2021. Interplant distances were also measured and recorded on 04/07/2021. On 08/09/2021, the harvest yield, canola biomass and ryegrass biomass in each plot were recorded in t/ha, and ryegrass tiller counts were made on 15/11/2021. Grain quality information, including the protein content, moisture content, oil content and temperature, were also recorded subsequent to harvest.

数据源自2021年默雷丁地区油菜播种试验。该试验对比了不同密度下油菜与黑麦草竞争的建立情况（油菜密度为5种，黑麦草密度为3种），以及使用圆锥式播种机与Monosem精量播种机的情况。实验由阿德莱德大学主持的UOA1803-009RTX GRDC研究项目实施，实验设计和数据收集由西澳大利亚免耕农民协会（WANTFA）在默雷丁当地管理。文件：2021 Merredin canola.xlsx
实验设置：实验由西澳大利亚免耕农民协会（WANTFA）在本地管理。试验以分块设计进行，包括5种油菜密度（10、15、20、30和40株/平方米的目标植物），3种竞争性黑麦草密度（无、低和中等）以及两种不同的播种机（传统圆锥式播种机与Monosem精量播种机）。设计嵌入在包含30行（不包括两侧的两个缓冲区域）和3个重复列的空间网格中，共计90个地块。记录的变量：植株建立数量（油菜和黑麦草/平方米）、株间距离（厘米）、油菜生物量（吨/公顷）、黑麦草生物量（吨/公顷）、油菜产量（吨/公顷）、蛋白质含量（百分比）、水分含量（百分比）、油分含量（百分比）、温度（摄氏度）、黑麦草分蘖计数。
数据收集和评估：收获日期记录为2021年8月9日。于2021年4月7日在每个地块进行了3次植株计数，包括油菜和黑麦草。株间距离也在同一天进行了测量和记录。在2021年8月9日，记录了每个地块的收获产量、油菜生物量和黑麦草生物量（吨/公顷），并在2021年11月15日进行了黑麦草分蘖计数。收获后的谷物质量信息，包括蛋白质含量、水分含量、油分含量和温度，也随后被记录。
