Optimising Plant Establishment 2020 Inverleigh Canola Experiment

Data from the 2020 crop establishment trial at Inverleigh, VIC. The trial compared the establishment of Hyola 580CT canola at different target plant 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).Files:2020 SFS canola.xlsxExperiment setup:Experiment managed locally by Southern Farming Systems (SFS). The trial was organised as a randomised complete block design with four treatments (conventional seeder vs precision seeder, by two different target plant densities 25 and 50 plants/m2), arranged in a single column with 12 rows, 3 replicates (so 12 plots total). Hyola 580CT canola was sown as the variety in this trial.Variables recorded:establishment count (plants/m2), interplant distance (cm), peak biomass wet weight (g), peak biomass dry weight (g), peak biomass moisture (%), peak biomass (t/ha), harvest biomass wet weight (g), harvest biomass dry weight (g), harvest biomass moisture (%), harvest biomass (t/ha), harvest index, yield (kg/plot), protein (%), oil (%), corrected yield at 8% moisture (t/ha), test weight (kg/hL), 1000-grain weight (g)Data collection and assessment:The canola was sown on 26/05/2020. Only final establishment counts were made for the canola crop, as there were difficulties with ground larks and earwigs during the preliminary emergence observations. Interplant distances were recorded between successive seedlings for each plot. Peak biomass and harvest biomass cuts were made to assess wet weight, dry weight and moisture content, and at harvest the yield (in kg/plot and corrected to 8% moisture), moisture content, oil content and 1000-grain weight were assessed.本数据集源自澳大利亚维多利亚州（VIC）因弗利（Inverleigh）2020年作物定植试验。该试验对比了Hyola 580CT油菜（canola）在两种目标种植密度下的定植效果，分别采用常规播种机（Vaderstad Rapid）与精密播种机（Vaderstad Tempo）实施，目标密度为25株/㎡与50株/㎡。本试验隶属于阿德莱德大学（University of Adelaide）主导的GRDC研究项目UOA1803-009RTX，试验实施与本地数据采集工作由南部农业系统（Southern Farming Systems，缩写SFS）统筹。 数据集文件：2020 SFS canola.xlsx 试验设计：本试验采用随机完全区组设计，共设置4组处理（常规播种机/精密播种机×25株/㎡/50株/㎡两种目标密度），布局为单列12行区组，设置3次重复，总计12个试验小区。本试验供试品种为Hyola 580CT油菜。 记录变量：定植密度（株/㎡）、株间距离（cm）、峰值生物量鲜重（g）、峰值生物量干重（g）、峰值生物量含水率（%）、峰值生物量（t/ha）、收获期生物量鲜重（g）、收获期生物量干重（g）、收获期生物量含水率（%）、收获期生物量（t/ha）、收获指数、小区产量（kg/小区）、籽粒蛋白质含量（%）、籽粒含油率（%）、含水率校正至8%后的产量（t/ha）、容重（kg/hL）、千粒重（g）。 数据采集与评估：供试油菜于2020年5月26日播种。由于预出苗观测阶段受云雀与蠼螋虫害干扰，仅完成了最终定植密度的统计。各试验小区内连续植株的株间距离均被记录。试验通过刈割获取峰值生物量与收获期生物量样本，分别测定其鲜重、干重与含水率；收获阶段则测定小区产量（以kg/小区为单位并校正至含水率8%）、籽粒含水率、含油率及千粒重。
