Creating field name programmatically

HI,

I am trying to create a Note field programmatically. I have used the below code:

string fieldtestComments = list.Fields.Add("InserttesterAdjustersCommentsHere", SPFieldType.Note, false);

list.Fields[fieldtestComments].Update();

However, the field name is only taking till "InserttesterAdjustersCommentsHer". Only 32 characters are getting taken. However, I am able to create the same column from UI as "InserttesterAdjustersCommentsHere".

How to fix this?

Thanks
