Wheat-Bean mixed cropping trials under organic management from 2015 to 2018

This database originates from field trials conducted between 2015 and 2018 by CREABIO at the La Hourre experimental site (southwestern France) and was compiled by ITAB. The aim of these trials is to investigate the impact of different varieties on the performance of wheat–faba bean mixed-cropping. Each treatment corresponds to the combination of a soft wheat (Triticum aestivum) variety and faba bean (Vicia faba), under sowing densities of 280 seeds/m2 for wheat and 25 seeds/m2 for fava bean. A total of 9 soft wheat varieties and 1 faba bean variety are tested. The mixed cropping is compared to two sole-crop controls: pure wheat and pure faba bean.The trials followed a split-plot design with 3 replicates.The database includes information on: - Field operations: sowing, fertilization, weed control, and harvesting- Production performance: grain yield, protein content, specific weight- Yield components: plants density (plants/m²), ears density (ears/m²), pods density (pods/m²) and grains density (grains/m ²)- Wheat growth monitoring: early and late growth habit, vegetative and reproductive phase vigour and height at maturity- Disease susceptibility to several pathogens: Zymoseptoria tritici (Mycosphaerella graminicola), Puccinia striiformis (P. glumarum), and Puccinia recondita. In addition, 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, along with 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
