In brief: No
Although kidney donors may lose a small amount of blood during their surgery, this doesn't usually cause anemia.
In terms of red blood cell production, this is driven by a hormone called erythropoeitin that is made by the kidney(s). Research has shown that the remaining kidney is able to compensate and produce enough erythropoeitin to maintain red blood cells and avoid anemia in the donor.

After living kidney donation, the overall renal function returns to about 65-70% of that pre-donation. That is sufficient to produce normal blood formation without anemia,
In brief: No
After single kidney donation, the patient will actually lose about 30% (not 50%) of their total kidney function since the remaining kidney will usually hypertrophy (enlarge) if the donor is under age 60.
This amount of residual kidney function will not result in anemia (low red blood cell count).
