Warwickshire were indebted to a 108-run ninth-wicket stand between Chris Woakes and Chris Wright as they battled back against LV= County Championship Division One high-fliers Nottinghamshire at Edgbaston.
After the Bears’ top-order slipped up, Woakes and Wright both hit valuable half-centuries to usher the hosts past the follow-on.
Nottinghamshire reached one without loss at the close after Steven Mullaney and nightwatchman Luke Fletcher, who took the first ball, negotiated two overs.
England batsman Trott made 23 in his first championship innings in more than two months.
Wicket: The first of the reply goes to Peter Siddle, Porterfield nicking to Read, his 900th FC catch. 31-1 #WarksvNotts

Trott, making his first-class comeback following a second break from cricket to recover from the stress-related illness that forced him to return early from the winter Ashes tour, batted for 47 minutes and faced 31 balls before he was lbw shuffling across his stumps to Andre Adams.
Adams finished with 4-67 as he helped cut a swathe through the home top order either side of lunch before Woakes and Wright resisted.
At one point it appeared that Trott might have a second innings in the day as Warwickshire slipped to 188 for seven, still 69 away from saving the follow-on, but Woakes averted the threat with some spirited tail-end resistance from Jeetan Patel and then Wright.
Woakes and Wright also struck early with the ball to wrap up Nottinghamshire's last three wickets inside 25 minutes, but not before they had secured maximum batting points.
Fletcher clipped Wright to square-leg where Trott held a comfortable catch, Adams drove Woakes to long-on and Gurney was bowled giving himself room against Woakes.
Despite losing their last five wickets for 10 runs, Nottinghamshire's total of 406 soon looked daunting when Will Porterfield edged Siddle to give Chris Read the 900th first-class catch of his career.
Difference between the two teams on first inns is 63, max bonus points again for Notts.

Trott's departure was quickly followed by Warwickshire's acting captain Varun Chopra, who was bowled middle stump by Fletcher for 33, and Tim Ambrose who went lbw playing back to one from Adams that kept a shade low.
Sam Hain nibbled Siddle to Read, Rikki Clarke clipped Adams to midwicket and Keith Barker was taken by Riki Wessels who sprawled forward to take a rebound off Samit Patel at second slip.
Woakes began the recovery with Jeetan Patel, whose run-a-ball 24 ended with a smart catch by Samit Patel at second slip off Siddle, and continued it with Wright.
Woakes, who batted for four hours, was bowled in sight of his ninth first-class century and Wright, who clobbered 14 fours from 79 balls, chanced his arm once too often when he gave himself too much room trying to carve Siddle.
Australian fast bowler Siddle, talking of bowling to Trott again, said: "It was nice to get him early. He is one of those blokes that you don't want to get in and see out there for too long because you know he can go big."
On his recovery partnership with Wright, Woakes said: "I thought Chris was going to get past me the way he was going. The old ball got a bit soft and I was finding it difficult, but Chris was finding it easy.
"We are 60 behind and we wanted to be level but, from where we were, we will take this position."
