Paul Tisdale's side are currently in third position in League 2.
MK Dons had a great month in March, picking up 13 of a possible 18 points, resulting in Paul Tisdale being nominated for the Manager of the Month award.
Tisdale used all his experience of previous promotion campaigns with Exeter to calm nerves at MK when results began slipping earlier in the calendar year. Four wins and a draw from six games lifted his side back into the top two.
The winners will be revealed on Friday 12th April.
