Beelbangera 2024 Long Coleoptile Wheat Trials: Genotype, Sowing Depth, Fertiliser, and Seed Size Interactions for Early Establishment and Yield Performance

This dataset comprises detailed agronomic data from three coordinated field experiments conducted at Beelbangera, NSW. The trials investigate the effects of genotype, sowing depth, fertiliser placement and rate, and seed size on wheat establishment and yield performance.\nThe Excel workbook contains 14 sheets, which include trial details, site maps, treatment layouts, packet plans, raw plot-level data, processed metrics, and harvest index calculations. The data is structured with consistent identifiers such as run number, genotype, sowing depth, fertiliser treatment, and seed size category. Raw data entries include grain yield per plot, sowing depth, genotype, fertiliser rate, and plot dimensions, enabling calculation of yield per hectare. Additional sheets provide derived metrics such as grain count, canopy cover, SAVI (Soil Adjusted Vegetation Index), and harvest index.\nData was collected using standard field trial methodologies. Sowing was performed on 29 April 2024 using a Morris seeder at two depths: shallow (4 cm) and deep (12–14 cm). Fertiliser was applied either with the seed or above the seed, at safe (80 kg/ha MAP) and unsafe (160 kg/ha MAP) rates. Trials were replicated three times with consistent plot sizes (12 m × 1.75 m) and row spacing (25 cm × 7 rows). Environmental conditions were monitored, including rainfall (362.5 mm total, 246 mm in the growing season), and soil tests were conducted pre-sowing (pH 6.2, total N 57 kg/ha, Colwell P 38 ppm). Herbicide and fertiliser applications were logged with dates and rates.\nThe dataset includes over 100 variables. Key fields include genotype (e.g., Calibre, Mace18, Magenta13), sowing depth, fertiliser rate and placement, seed size (e.g., small, medium, large), grain yield, biomass, spike count, and vegetation indices. Codes such as “SS” and “DS” denote sowing depth, while “Std”, “Lge”, “Sml”, “Med”, and “Vlge” refer to seed size categories. Fertiliser treatments are coded as “Cont”, “Withseed”, and “Aboveseed”. The dataset also includes image references for visual assessments and positional metadata for canopy measurements.\n

本数据集涵盖澳大利亚新南威尔士州比尔班格拉（Beelbangera）开展的3项协同田间试验的详细农艺数据。本系列试验旨在探究基因型、播种深度、肥料施用方式与施用量以及种子大小对小麦出苗定植及产量表现的影响。
本Excel工作簿包含14个工作表，涵盖试验详情、地块分布图、处理方案布局图、种子袋分配计划、样地原始数据、加工后指标以及收获指数计算结果。数据采用统一标识符进行结构化组织，包括试验批次号、基因型、播种深度、肥料处理方案以及种子大小类别。原始数据条目包含每样地产量、播种深度、基因型、肥料施用量以及样地尺寸，可用于计算公顷产量。其余工作表则提供衍生指标，包括籽粒计数、冠层覆盖率、土壤调整植被指数（Soil Adjusted Vegetation Index，SAVI）以及收获指数。
数据采用标准田间试验方法采集。试验于2024年4月29日开展，使用莫里斯（Morris）播种机进行播种，设置两个播种深度：浅播（4厘米）与深播（12–14厘米）。肥料采用随种施用或种面施用两种方式，施用量设置为安全用量（80公斤/公顷单磷酸铵（MAP））与非安全用量（160公斤/公顷单磷酸铵（MAP））。试验设置三次重复，样地尺寸统一为12米×1.75米，行距为25厘米，共7行。试验监测了环境条件，包括降雨量（总降雨量362.5毫米，生育期降雨量246毫米），并在播种前开展土壤测试（pH值6.2，全氮57公斤/公顷，科尔韦尔有效磷（Colwell P）38 ppm）。除草剂与肥料的施用时间及施用量均有详细记录。
本数据集包含超过100个变量，核心字段包括基因型（例如Calibre、Mace18、Magenta13）、播种深度、肥料施用量与施用方式、种子大小（例如小、中、大）、籽粒产量、生物量、穗数以及植被指数。代码"SS"与"DS"代表播种深度，而"Std"、"Lge"、"Sml"、"Med"及"Vlge"则对应种子大小类别。肥料处理方案的代码为"Cont"、"Withseed"与"Aboveseed"。本数据集还包含用于视觉评估的图像引用信息，以及冠层测量所需的位置元数据。
