The trial involved three experiments using the Mace18 genotype (Experiments 1 and 2) and Calibre (Experiment 3), with treatments including two sowing depths (shallow: 4\u20135 cm and deep: 10\u201312 cm), two seed sizes (standard and small), and multiple fertiliser placements (above, with, below seed, sideband, and twin-row configurations). The experiment was laid out in a randomised block design with four replicates, using 12 m \u00d7 2.2 m plots and 28 cm row spacing.\n\nThe Excel file (.xlsx) contains seven sheets. \u201cTrial details\u201d outlines the experimental design, site conditions, and agronomic practices including sowing date (7 May 2024), fertiliser regimes, and rainfall data. \u201cTrial Plan Exp1\u201d and \u201cTrial Plan Exp2&3\u201d detail plot layouts and treatment combinations for each experiment. The \u201cMetafile\u201d provides metadata including sowing depths, assessment dates, and measured variables. The dataset in \u201cExp1_data\u201d includes 40 plots with variables such as plant density at five time points, emergence percentage, sowing depth, coleoptile length, root and shoot biomass, NDVI across ten dates, dry biomass at GS31, GS65, and GS89, spike number, grain yield, harvest index, and 1000-grain weight. The \u201cExp1_soildata\u201d sheet provides gravimetric soil moisture content at three depths (0\u20135, 5\u201310, 10\u201315 cm) for selected plots, measured on two dates post-sowing.\n\nThe dataset includes over 50 variables. Treatment labels (e.g., \u201cdeep_Small_fert below\u201d) encode depth, seed size, and fertiliser placement. Biomass is recorded in g/m\u00b2, NDVI as unitless indices, and grain yield in t/ha. Soil moisture is expressed as percent weight/weight. Data were collected using standard field protocols, with plant assessments based on averages from 10 plants per plot. This dataset enables detailed analysis of how agronomic practices influence early wheat establishment, biomass accumulation, and final yield under low rainfall conditions.", "num_resources": 0, "num_tags": 0, "organization": {"id": "aa2e8465-918a-44d1-aaab-34b7632fa3e5", "name": "csiro-data-access-portal", "title": "CSIRO Data Access Portal", "type": "organization", "description": "Harvester for CSIRO Data Access Portal", "image_url": "", "created": "2025-06-23T12:29:12.193044", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://data.csiro.au", "href": "https://data.csiro.au/collection/csiro:66394", "title": "CSIRO DAP"}, "owner_org": "aa2e8465-918a-44d1-aaab-34b7632fa3e5", "private": false, "promotion_level": "0", "spatial": "Australia", "state": "active", "temporal_coverage_from": "2000-01-01 00:00:00", "title": "Wynarka 2024 Long Coleoptile Wheat Trial: Effects of Sowing Depth, Fertiliser Placement, and Seed Size on Early Growth and Yield", "type": "dataset", "unpublished": false, "url": null, "version": null, "resources": [], "tags": [], "groups": [], "relationships_as_subject": [], "relationships_as_object": [], "extras": [{"key": "harvest_object_id", "value": "e66f5c21-ac9b-4f65-8f06-753c34b92d13"}, {"key": "harvest_source_id", "value": "74e2544e-7627-4cb4-b9ba-1d4a043af4f3"}, {"key": "harvest_source_title", "value": "CSIRO DAP"}]}}
