BIOLOGICAL NITROGEN FIXATION OF DIFFERENT LEGUME
SPECIES UNDER WATER STRESSBIOfix - Project

• Greenhouse trial

2
Research questions

• What is the biological nitrogen fixation
  (capacity) of different alfalfa varieties under
  different (three levels) soil water supply?
• What is the above and belowground yield and
  shoot/root ratio of different alfalfa varieties
  under different (three levels) soil water supply?
• What is relative evapotranspiration rate (RETR)
  and total water potential of different alfalfa
  varieties under different (three levels) soil
  water supply?
