Cereal-Pea mixed cropping trials under organic management from 2010 to 2015

This database originates from field trials conducted between 2010 and 2015 by CREABIO at the La Hourre experimental site (southwestern France) and was compiled by ITAB. These trials aimed to investigate cereal–pea intercropping systems under organic management. Each treatment corresponded to the association of one cereal species with one pea variety, under various sowing densities. A total of 34 treatments were implemented, involving 4 soft wheat (Triticum aestivum) varieties, 4 barley (Hordeum vulgare) varieties, 1 oat (Avena sativa) variety, 1 triticale (× Triticosecale) variety, 6 pea varieties, and 1 faba bean (Vicia faba) variety.The trials were conducted using a split-plot design with 3 replicates.The database includes information on:- Field operations: sowing, fertilization, weeding, and harvesting- Production performance: grain yield, protein content, specific weight, aboveground residue biomass quantity and nitrogen content- Yield components: plants density (plants/m²), ears density (ears/m²), pods density (pods/m²), grains density (grains/m ²) and ITCF index- Growth monitoring: cereal height at maturity, cereal dry biomass quantity and nitrogen content at different stages: flowering, ears 1cm- Disease susceptibility to anthracnose. In addition, the database contains daily meteorological data (minimum, maximum, mean temperature and rainfall) recorded at the on-site weather station throughout the experimental period, as well as several soil descriptors. 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
