Or, did you sow the seed direct or try transplanting the seedlings? Damage the tiny tap root when they are moved and you get that problem.
Get a long metal rod, put it in your soil, to a depth of about 18 inches, Move it around in a circular motion making a cone shaped hole in the ground. Fill that with sifted soil and sow the parsnip on top.
