The trial included six wheat genotypes (e.g., Mace18, Scepter, Calibre, Magenta, Magenta13, Mace) sown at two depths (shallow: 30\u201340 mm and deep: 80\u2013100 mm) under three presswheel pressure treatments (light, standard, heavy). The experiment was laid out in a randomized block design with four replicates, using 12 m \u00d7 2.2 m plots and 28 cm row spacing. Fertiliser treatments varied by placement (above, with, or below seed) and rate (standard, high), and seed size (standard or small) was recorded for each plot.\n\nThe Excel file (.xlsx) contains seven sheets. The \u201cTrial details\u201d sheet outlines the experimental design, site conditions, soil test results, and assessment schedule. The \u201cTrial plan\u201d sheet maps plot layout and treatment combinations. The \u201cMetafile\u201d provides metadata including sowing date, genotype list, and measured variables. The \u201cExp_data\u201d sheet is the core dataset, containing 56 plots with variables such as plant density at three time points, sowing depth, coleoptile length, root and shoot biomass, NDVI at two dates, dry biomass at GS31 and GS65, grain yield, protein content, 1000-grain weight, and harvest index. The \u201cExp_soildata\u201d sheet includes gravimetric soil water content at three depths (0\u20135, 5\u201310, 10\u201315 cm) for selected plots. The \u201cpredicta B\u201d sheet reports soil-borne pathogen DNA levels and nematode counts across depths and blocks. The \u201csoil fertility\u201d sheet provides detailed chemical and physical soil properties (e.g., pH, organic carbon, macro- and micronutrients, salinity, texture) across five depth intervals (0\u2013100 cm).\n\nThe dataset includes over 40 variables. Codes such as \u201cdeep_Small_fert with_High rate\u201d describe treatment combinations. Depths are in mm, biomass in t/ha, and nutrient concentrations in standard agronomic units. The dataset supports analysis of genotype performance under varying mechanical and environmental constraints, with implications for optimizing deep sowing strategies in low rainfall environments.", "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:66395", "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": "Waikerie 2024 Long Coleoptile Wheat Trial: Genotype, Sowing Depth and Presswheel Pressure Effects on Early Establishment 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": "ab360871-5070-4003-be6c-9bf9830b5bcd"}, {"key": "harvest_source_id", "value": "74e2544e-7627-4cb4-b9ba-1d4a043af4f3"}, {"key": "harvest_source_title", "value": "CSIRO DAP"}]}}
