I assume you're talking about radials laying on the ground?

Rudy Severns (N6LF) has studied this with both models and field experiments
http://www.antennasbyn6lf.com/

In particular look at his presentation on tests

To a certain extent it depends on your soil properties, but his take 
home is that more shorter radials is better until you get to around 16 
radials...
