Kindly identify this leafy vegetable photographed on a farm in Anuppur district, Madhya Pradesh in March 2019.
Pl. check comparative images at 

over grown sarsav ka saag: brassica juncea?
but if it is overripe leaves where are the mustard pods? the bluish leaves are brassica also 

The farmer calls it zingy mustard, must be as you say a cultivar of sarson ka saag.
do the farmers find mustard seed pods?
Pl. also check comparative images at Brassica

Most probably Brassica juncea  var. japonica. 

Thanks, … But I could not find any such variety in Catalogue of Life.
Could it be Brassica rapa var. japonica?
