Dry matter yield and nitrogen fixation of Pisum sativum and Vicia faba at elevated CO2 and three nitrogen levels.

The dataset provides information about the effect of elevated CO2 and N addition on the biomass yield and the percentage of nitrogen derived from air (%Ndfa) of two legume species, Pisum sativum L. and Vicia faba L. The experiment was carried out under controlled conditions in growth chambers

本数据集提供了关于提高二氧化碳浓度及氮添加对两种豆科植物（豌豆L. pisum sativum及蚕豆L. vicia faba）生物量产量及氮气中氮占比（%Ndfa）影响的信息。该实验在可控的生长室条件下进行。
