Optimising Plant Establishment 2019 Roseworthy Canola & Faba Bean Experiment

Data from the 2019 crop establishment trials at Roseworthy, SA. The trials compared the establishment of Hyola 559TT canola and Samira faba bean seeded at different target densities, under a conventional cone seeder and under a precision seeder, with the faba bean trial additionally considering graded vs ungraded seeding treatments. The experiment was run under the UOA1803-009RTX GRDC research project, led and managed locally by the University of Adelaide.Files:2019 Roseworthy Canola.xlsx, 2019 Roseworthy Faba bean.xlsx, Soil moisture 2019.xlsx, Soil temperatures & emergence data 2019.xlsxExperiment setup:The faba bean trial was organised as a randomised complete block design with 8 treatments (containing combinations of the cone seeder vs precision seeder, graded and ungraded seeds, and with two different target seeding densities at 10 and 20 plants/m2), arranged spatially in two columns containing two replicates each, for a total of 32 plots. The variety sown was Samira faba bean.The canola trial was organised as a randomised complete block design with 8 treatments (containing combinations of the cone seeder vs precision seeder, with four different target seeding densities at 10, 20, 40 and 80 plants/m2), arranged spatially in two columns containing two replicates each, for a total of 32 plots. The variety sown was Hyola 559TT canola. The canola trial was sown directly east of the faba bean trial, with separating border plots and with the same alignment and spatial dimensions. Variables recorded:establishment count (plants/m2), soil moisture (% Volumetric Water Content), soil temperature (degrees Celsius), yield (g/plot), canola 1000-seed weight (g), faba bean 200-seed weight (g)Data collection and assessment:Both trials were sown on 24/05/2019. Plant emergence counts were taken by counting the number of seedlings in the middle two rows along a 3m row length. The canola trial establishment counts were made roughly every two days between 31/05/2019 and 19/06/2019, with an extra final establishment count being made on 28/06/2019. The faba bean emergence counts were made roughly every two days between 08/06/2019 and 19/06/2019, with an extra final count on 28/06/2019. After each count, soil moisture was measured using MPM moisture probes placed in the centre of each plot, with the logged volumetric water content readings recorded in full in the 'Soil moisture 2019.xlsx' spreadsheet. Three soil temperature data loggers were used to record soil temperature information at 10cm depth between 30/05/2019 and 12/07/2019, and this data is available in the 'Soil temperatures & emergence data 2019.xlsx' spreadsheet. At harvest, the yield (in g/plot) was recorded for both the canola and faba bean trials. The canola 1000-seed weight was recorded in grams, and the faba bean 200-seed weight was recorded in grams.

本数据集收录了2019年在南澳大利亚罗斯沃西地区进行的作物种植试验数据。试验内容涉及不同目标密度下，采用传统圆锥式播种机和精量播种机种植Hyola 559TT油菜和Samira豇豆的出苗情况，其中豇豆试验还进一步考虑了分级与非分级播种处理。该实验是在UOA1803-009RTX GRDC研究项目下进行的，由阿德莱德大学负责领导和实施。相关文件包括：2019 Roseworthy Canola.xlsx，2019 Roseworthy Faba bean.xlsx，Soil moisture 2019.xlsx，Soil temperatures & emergence data 2019.xlsx。
实验设置：豇豆试验按照随机完全区组设计进行，共设有8种处理（包括圆锥式播种机与精量播种机的组合、分级与非分级种子，以及两种不同的目标播种密度，分别为10和20株/平方米），空间上排列成两列，每列包含两个重复，总计32个地块。播种的品种为Samira豇豆。油菜试验同样采用随机完全区组设计，设有8种处理（包括圆锥式播种机与精量播种机的组合，以及四种不同的目标播种密度，分别为10、20、40和80株/平方米），空间上排列成两列，每列包含两个重复，总计32个地块。播种的品种为Hyola 559TT油菜。油菜试验直接播种于豇豆试验东侧，并设有隔离边界地块，保持相同的对齐方式和空间尺寸。
记录的变量：出苗数量（株/平方米）、土壤水分（体积含水率百分比）、土壤温度（摄氏度）、产量（克/地块）、油菜千粒重（克）、豇豆百粒重（克）。
数据收集与评估：两项试验均于2019年5月24日播种。通过在3米行长的中间两行中计数幼苗数量来记录植株出苗数。从2019年5月31日至6月19日，大约每两天对油菜试验的出苗数量进行一次计数，并在6月28日进行最后一次计数。从2019年6月8日至6月19日，大约每两天对豇豆试验的出苗数量进行一次计数，并在6月28日进行最后一次计数。每次计数后，使用放置在每个地块中心的MPM水分探头测量土壤水分，并将记录的体积含水率读数完整记录在'Soil moisture 2019.xlsx'工作表中。使用三个土壤温度数据记录器在2019年5月30日至7月12日之间记录10厘米深度的土壤温度信息，该数据可在'Soil temperatures & emergence data 2019.xlsx'工作表中找到。收获时，记录了油菜和豇豆试验的产量（克/地块）。油菜的千粒重以克为单位记录，豇豆的百粒重以克为单位记录。
