This database originates from field trials conducted between 2007 and 2017 by CREABIO at the La Hourre experimental site (southwestern France) and was compiled by ITAB. These trials aimed to evaluate the effect of fertilization on soft wheat (Triticum aestivum) cultivation under organic management. A total of 37 treatments were tested. Each treatment corresponded to a combination of a fertilizer dose (in nitrogen unit), fertilizer type (ex. Bone meal), application timing (wheat development stages, ex. Ears 1cm), and application method (hoeing versus non-hoeing).The trials were conducted using a split-plot design with 4 replicates.The database includes information on: - Field operations: sowing, fertilization, weed control, and harvesting- Production performance: grain yield, specific weight and protein content- Yield components: plants density (plants/m²), ears density (ears/m²) and grains density (grains/m ²)- Growth monitoring: aboveground residue biomass quantity and nitrogen content, wheat dry biomass quantity and nitrogen content at different stages: ears 1cm, flowering- Soil mineral nitrogen content at different horizons Additionally, the database contains daily meteorological data (minimum, maximum, and mean temperatures, as well as precipitation) recorded at the on-site weather station throughout the trial period. This dataset is part of the database compiled as an outcome of Work Area 1 in project OrganicYieldsUP. Variable definitions can be found here: https://doi.org/10.5281/zenodo.15276082
