Optimising Plant Establishment 2021 Wallup Faba Bean Experiment

Data from the 2021 crop establishment trial at Wallup, VIC. The trial compared the establishment of PBA Bendoc faba bean at different densities, under a conventional cone seeder and under a precision seeder, and at two different row spacings (narrow 12" row spacing vs wide 15" row spacing). The experiment was run under the UOA1803-009RTX GRDC research project led by the University of Adelaide, and the experiment and data collection were managed locally in Wallup by the Birchip Cropping Group (BCG).Files:2021 Birchip faba bean.xlsxExperiment setup:This experiment was managed locally by the Birchip Cropping Group (BCG). The trial was organised as a split split plot with 4 treatments of target plant densities (10, 15, 20 and 30 plants/m2), two different row spacings (narrow 12" row spacing vs wide 15" row spacing), and two different seeders (conventional cone seeder vs precision seeder), with 4 replicates. The design was embedded in a spatial grid with 16 rows (not including two buffer rows on either side of the trial extent), and 4 ranges, for 64 plots total. The variety of faba bean used in this Wallup trial was PBA Bendoc.Variables recorded:establishment count (plants/m2), seedling depth (mm), interplant distance (cm), NDVI, biomass weight (g), biomass (t/ha), plant number, yield (t/ha), 1000-grain weight (g), seed count (seeds/m2)Data collection and assessment:Plant emergence rates were counted for each plot on 10 separate occasions between 01/06/2021 and 05/07/2021, and establishment counts for each plot were recorded in plants/m2. Seedling depths were recorded for 5 plants across two rows each, but only for two of the treatment combinations. Interplant distances were measured by paddock survey. NDVI measurements were made on 20/08/2021. Biomass cuts were taken and weighed at Growth Stages 30 and 99, with the weights recorded in grams, biomass recorded in t/ha, and biomass plant counts recorded. At harvest, the yield in t/ha, the 1000-grain weight in g, and the number of seeds/m2 were recorded.

本数据集采自澳大利亚维多利亚州（VIC）沃勒普（Wallup）2021年作物建植试验。本试验对比了PBA Bendoc蚕豆在不同种植密度、常规圆锥式播种机与精密播种机配置下，以及两种行距（窄行12英寸与宽行15英寸）条件下的建植效果。本试验隶属于阿德莱德大学（University of Adelaide）牵头的UOA1803-009RTX GRDC研究项目，试验实施与数据采集工作由伯奇普种植集团（Birchip Cropping Group，简称BCG）在沃勒普本地完成。

试验设计：
本试验由伯奇普种植集团（BCG）负责本地实施。试验采用裂裂区设计，设置4个目标种植密度处理（10、15、20、30株/平方米）、2种行距配置（窄行12英寸与宽行15英寸）、2种播种机具（常规圆锥式播种机与精密播种机），共4次重复。试验采用空间网格布局，包含16条种植行（不含试验范围两侧各设置的2条保护行）与4个区组，总计64个试验小区。本次沃勒普试验所用蚕豆品种为PBA Bendoc。

记录变量：
建植株数（株/平方米）、幼苗埋深（毫米）、株间距离（厘米）、归一化植被指数（NDVI）、生物量重量（克）、单位面积生物量（吨/公顷）、株数、籽粒产量（吨/公顷）、千粒重（克）、单位面积籽粒数（粒/平方米）

数据采集与评价：
2021年6月1日至7月5日期间，共10次对每个试验小区的出苗率进行计数，并以株/平方米为单位记录各小区的建植株数。仅针对2个处理组合，对2条种植行内的5株幼苗分别测量其埋深。株间距离通过田间踏勘测量获取。归一化植被指数（NDVI）的测定于2021年8月20日完成。分别在作物生长阶段30与99时进行生物量取样并称重，称重结果以克为单位记录，同时记录单位面积生物量（吨/公顷）与取样株数。收获期记录籽粒产量（吨/公顷）、千粒重（克）与单位面积籽粒数（粒/平方米）。
