e0“A greenhouse pot experiment was conducted to study the temporal dynamics of N2 fixation of alfalfa(Medicago sativa L.) grown alone and in mixture with smooth bromegrass(Bromus inermis Leyss.) in response to the addition of fertilizer N”
e3“When grown as a mixture, smooth bromegrass biomass was increased significantly by N application, resulted in a decrease in alfalfa biomass”

Other claims from this paper (8)
- Intervention effect Alfalfa grown alone did not show a significant dry matter increase with added fertilizer N in the greenhouse pot experiment.
- Intervention effect Smooth bromegrass grown alone had significantly increased dry weight and N content with N application in the greenhouse pot experiment.
- Intervention effect In mixture, N application decreased alfalfa biomass.
- Intervention effect Individual alfalfa plant dry weight (shoots plus roots) was significantly lower in mixture than when grown alone at all N levels.
- Intervention effect Smooth bromegrass shoot and root dry weight were significantly higher when grown with alfalfa than when grown alone, regardless of N level.
- Association When grown alone, alfalfa N2 fixation was reduced with N fertilization (R2=0.9376, P=0.0057).
- Association With 75 kg ha-1 N fertilizer in mixture with smooth bromegrass, alfalfa %Ndfa reached a maximum of 84.07 and 83.05% in the 2nd and 3rd harvests.
- Association Total 3-harvest %Ndfa of alfalfa was higher when grown in a mixture than when grown alone.
