Srivastava (118 batting) and former India A player Saxena (109) added 222 for the opening stand as Bengal bowlers had little cheer on a flat deck at the Holkar Stadium.
Such was the plight of the Bengal attack that the only wicket of the day was taken by Manoj Tiwary, who bowls part-time leg-breaks.
None of the senior bowlers including Ashok Dinda (0/68 in 19 overs) , Saurashish Lahiri (0/36 in 14 overs) and Laxmi Ratan Shukla (0/51 in 18 overs) couldn't make much of an impact.
The more experienced Saxena scored his 10th first class ton and faced 191 balls with 19 boundaries to his credit.
Bengal team management finally dropped veteran opener Arindam Das and picked young Abhishek Das in his place.
Brief Scores: Madhya Pradesh 274/1 in 90 overs (Aditya Srivastava 118 batting, Jalaj Saxena 109, Manoj Tiwary 1/21) vs Bengal.
