Optimising Plant Establishment 2020 Rupanyup Faba Bean Experiment

Data from the 2020 crop establishment trial at Rupanyup, VIC. The trial compared the establishment of faba bean at different densities, under a conventional cone seeder and under a precision seeder, and at two different row spacings (narrow vs wide rows). The experiment was run under the UOA1803-009RTX GRDC research project led by the University of Adelaide, and the experimental trial and data collection were managed locally in Rupanyup by the Birchip Cropping Group (BCG).<strong>Files:</strong>2020 Birchip faba bean.xlsx<strong>Experiment setup:</strong>Experiment managed locally by the Birchip Cropping Group (BCG). The trial was organised as a split split plot with 4 treatments of target plant densities (5, 10, 20 and 30 plants/m2), two different seeders used (conventional cone seeder vs precision seeder), and two different row spacings (narrow vs wide row spacings), with 4 replicates. The design was embedded in a spatial grid with 16 rows (not including the two buffer rows on either side of the trial extent) and 4 ranges, for 64 plots total.<strong>Variables recorded:</strong>establishment count (plants/m2), seedling depth (mm), interplant distance (cm), NDVI, biomass weight (g), biomass (t/ha), yield (t/ha), 1000-grain weight (g), harvest weight (kg), seed count (seeds/m2)<strong>Data collection and assessment:</strong>Plant establishment counts were measured in three 1-metre sections pinned across the plot, with the counts being made on 5 separate measuring occasions between 29/05/2020 and 17/06/2020. Sowing depths for the seedlings were recorded for 10 plants but for only two of the treatments. Interplant distances were also measured. NDVI measurements were made on 29/07/2020 and 23/09/2020 at each plot. Biomass cuts were taken and weighed at Growth Stages 65 and 99, with the weights recorded in grams. At harvest, the yield in t/ha, 1000-grain weight in g, harvest weight in kg and seeds/m2 were recorded.

本数据集源自澳大利亚维多利亚州（VIC）鲁帕尼尤普2020年作物出苗试验。本试验针对不同播种密度、两种播种设备（传统锥形播种机与精密播种机）以及两种行距配置（窄行距与宽行距）下的蚕豆出苗情况开展对比研究。本试验隶属于阿德莱德大学（University of Adelaide）牵头的UOA1803-009RTX澳大利亚谷物研究与开发公司（GRDC）研究项目，试验实施与数据采集工作由伯奇普作物集团（Birchip Cropping Group, BCG）在鲁帕尼尤普本地统筹完成。
**数据集文件：**2020伯奇普蚕豆.xlsx
**试验设计：**试验由伯奇普作物集团（BCG）本地负责实施。本试验采用裂裂区设计，设置4个目标种植密度处理（5、10、20、30株/平方米）、2种播种设备（传统锥形播种机与精密播种机）、2种行距配置（窄行距与宽行距），共设置4次重复。试验场地采用空间网格布局，包含16条种植行（不含试验区域两侧各2条缓冲行）与4个区组，总计64个试验小区。
**记录变量：**出苗数（株/平方米）、幼苗埋深（毫米）、株间距离（厘米）、归一化植被指数（NDVI）、生物量鲜重（克）、生物量（吨/公顷）、产量（吨/公顷）、千粒重（克）、收获总重量（千克）、单位面积种子数（粒/平方米）
**数据采集与评估：**出苗数通过在每个试验小区内布设3段1米样带进行统计，测定时段为2020年5月29日至2020年6月17日，共开展5次采样计数。仅针对2个处理组合的10株幼苗记录了播种埋深，同时测定了株间距离。归一化植被指数（NDVI）分别于2020年7月29日与2020年9月23日在每个试验小区完成测定。于作物生长阶段65与99时取样刈割生物量并称重，重量单位为克。收获期记录了单位面积产量（吨/公顷）、千粒重（克）、小区收获总重量（千克）以及单位面积种子数（粒/平方米）。
