Question

why did the congress did not come in open support of the peasantry

Answer 1

From its foundation on 28 December 1885 by A.O. Hume, a retired British officer, until the time India gained its independence on 15 August 1947, the Indian National Congress was considered to be the largest and most prominent Indian public organization, as well as the central and defining influence of the long Indian Independence Movement.[citation needed]

After India became independent, Mahatma Gandhi asked the leaders to dissolve Indian National Congress, and to form a new organisation to govern the nation.
