A detailed investigation of sugar beets differing in tolerance and resistance properties at fields with varying Heterodera schachtii infestation in Northern Germany was conducted. The effect of nematode infestation on water consumption, nitrogen uptake, yield and water use efficiency (WUE) of susceptible, tolerant and resistant sugar beet varieties was studied. Varietal differences in WUE were primarily associated with differences in yield. Yield of all varieties decreased with increasing nematode population while the susceptible variety showed the steepest decline. Nitrogen status of all vari...
