Optimising Plant Establishment 2018 Skipton Canola Experiment

Data from the 2018 crop establishment trial at Skipton, VIC. The trial compared the establishment of Wahoo canola at different densities, under a conventional seeder (Vaderstad Seed Hawk) and under a precision seeder (Vaderstad Tempo), and at two row spacings (a narrow row spacing of 250mm, and a wide row spacing of 500mm). 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).Files:2018 SFS Canola.xlsxExperiment setup:Experiment managed locally by Southern Farming Systems (SFS). The trial was organised as a split plot with 2 main plot treatments (the precision Tempo seeder vs the conventional Seed Hawk seeder) and 4 subplot treatments (two different row spacings 250mm vs 500mm, and two different target plant densities 25 and 35 plants/m2), arranged spatially in 4 ranges across 6 replicates, for 48 plots total. Wahoo canola was used as the variety.Variables recorded:establishment count (plants/m2), soil moisture (%), establishment score (0-10), peak biomass dry weight (kg/ha), uncorrected yield (t/ha), test weight (kg/hL), moisture (%), protein (%), oil (%), corrected yield at 8% moisture (t/ha)Data collection and assessment:The trial was sown on 02/05/2018 for the precision Tempo seeder, and on 03/05/2018 for the conventional Seed Hawk seeder. Plant establishment counts were made on 3m lengths at specified plots together with the soil moisture measurements, and these were counted on 22/05/2018 and 30/05/2018. During the establishment counts slug damage to many of the plots became apparent, and these have been noted in the trial map included in the dataset. The crop establishment was scored at each plot on 25/06/2018. Peak biomass dry matter was recorded for specified plots. The canola crop was harvested on 20/12/2018, and the yield (t/ha), moisture content, protein content and oil content were assessed.

数据集源自2018年维多利亚州斯基普顿的作物种植试验。该试验对比了在不同密度下，采用传统播种机（Vaderstad Seed Hawk）和精准播种机（Vaderstad Tempo）种植瓦胡亚油菜的情况，并分别以250毫米和500毫米的行距进行种植。实验由阿德莱德大学主持的UOA1803-009RTX GRDC研究项目实施，由南方农业系统（SFS）负责试验设计和本地数据收集。文件：2018 SFS Canola.xlsx
实验设置：由南方农业系统（SFS）在本地管理。试验采用裂区设计，包含两个主区处理（精准播种机Tempo与常规播种机Seed Hawk）和四个副区处理（两种不同的行距250毫米与500毫米，以及两种不同的目标植物密度25和35株/平方米），这些处理在6个重复中按空间排列，共48个小区。种植品种为瓦胡亚油菜。记录的变量包括：种植数量（株/平方米）、土壤含水量（%）、种植评分（0-10分）、峰值生物量干重（千克/公顷）、未校正产量（吨/公顷）、容重（千克/升）、水分（%）、蛋白质（%）、油脂（%）、8%水分下的校正产量（吨/公顷）。数据收集和评估：精准播种机Tempo于2018年5月2日播种，常规播种机Seed Hawk于5月3日播种。在指定小区的3米长度范围内进行了植物种植数量的统计，并测量了土壤含水量，这些数据于5月22日和5月30日收集。在种植数量统计过程中，许多小区出现了蛞蝓损害现象，这些情况已在数据集中包含的试验地图中标注。作物种植评分于2018年6月25日对每个小区进行。指定小区的峰值生物量干重被记录。油菜作物于2018年12月20日收获，对产量（吨/公顷）、水分含量、蛋白质含量和油脂含量进行了评估。
