Jadeja (103 not out) brought up his century with a brilliant cover drive off KS Shahabuddin before declaring the innings at 491 for 9 at the stroke of tea.
But the hosts' plan to snare some quick wickets was shelved by fading light as the umpire stopped play after just 4.4 overs were bowled in the Andhra innings.
Amit Pathak was batting on two while Alan Reddy was not out on one when stumps were drawn.
It was Jadeja at his best at the Roshanara cricket ground as the former international toyed with the Andhra attack, hitting 15 fours in his 170-ball knock.
He built important partnerships with N S Negi (49) and Sarandeep Singh (19) after the hosts looked like losing their way at lunch losing four wickets for 100 runs in the opening session.
There was a sense of urgency in the approach of the Delhi batsman after a crawl to 258 for 2 yesterday as they scored at a rate of almost four runs per over after overcoming a disastrous start which saw both their overnight batsmen -- Aakash Chopra (78) and Mithun Manhas (95) -- being dismissed within the first two overs.
Chopra was the first to go as he was trapped leg before wicket by Shahabuddin on the second ball itself. The pressure increased on the hosts further when Kalyankrishna clean bowled Manhas in the next over.
RVCH Prasad and Kalyankrishna ended with three wickets each while Shahabuddin chipped in with two wickets.
