Datasets for crop, soil properties and soil greenhouse gas emissions from an intercropping experiment with broccoli and fava bean

Datasets with all properties measured during three crop cycles of an experiment developed to assess the efficiency of intercropping between broccoli and fava bean to enhance crop productivity, soil health and carbon sequestration and storage and reduce soil greenhouse gas emissions and the use of external inputs. We compared a broccoli monocrop (<em>Brassica oleracea var. italica</em> Plenck), a fava bean monocrop (<em>Vicia faba</em> L.) and different broccoli-fava bean intercropping systems in three winter crop cycles: 2018/2019, 2019/2020 and 2020/2021. The intercropping systems were: i) mixed intercropping (alternation within the same row of broccoli and fava bean plants), row intercropping 1:1 (combination of alternate rows of broccoli - fava bean) and row intercropping 2:1 (combination of two rows of the broccoli crop and one row of fava bean).本数据集包含一项旨在评估西兰花与蚕豆间作效率的试验在三个作物生长周期内测得的全部性状数据，该试验以提升作物生产力、改善土壤健康水平、增强碳固存与碳储量、降低土壤温室气体排放及外部农资投入量为目标。本试验设置了单作西兰花（<em>Brassica oleracea var. italica</em> Plenck）、单作蚕豆（<em>Vicia faba</em> L.）以及多种西兰花-蚕豆间作体系共三类处理，并在2018/2019、2019/2020、2020/2021三个冬季作物周期内开展对比研究。所设置的间作体系具体包括：i) 同行混播间作（西兰花与蚕豆植株在同一行内交替种植）、1:1行比间作（西兰花与蚕豆行交替配置）以及2:1行比间作（2行西兰花搭配1行蚕豆的种植组合）。
