Narrative:

Aircraft X departed on a heading of 300 climbing to 4;000 feet. I first made radio contact with aircraft X at approximately 5 miles northwest of oma. On initial call I climbed aircraft X to 8;000 feet and turned to heading 220. As a single turboprop aircraft I expected the aircraft to make a 400 foot climb within 1-2 miles which they did not. On the heading 220 the aircraft entered a minimum vectoring altitude (MVA) area for a tower approximately 8 miles west of oma. When I became aware of the issue I turned the aircraft further to a 180 heading to avoid the obstruction and gave the instruction to expedite climb through 6;000 feet. I believe closest proximity to the obstruction was about 2 miles.as a controller with plenty experience in this facility; this is the first time I've had this type of situation occur. I would recommend to myself that I side with more caution with expectation of aircraft capabilities.
