Is there any milk/white sticky sap that comes from the plant when its broken ?

Im in a different zone and not familiar with your weeds but I would think that it blooms yellow and would start by checking two plant family's; Composite family- wild lettuces (Lactuca sp) and dandelions (Taraxacum sp), and the Mustard family (Sinapis sp). 

its more similar to lactuca Spp. i think!

Hi Khurshid

I agree that weed is Wild Lettuce

Dear Dr. Khurshid Bhat

It is difficult to identify a plant without flowers and fruits. It looks a Brassicaceae plant, most probably a species of genus Sisymbrium.

Good luck!

I agree with Dr. Singh

Yes, I agree with Dr. Arvind and without flowers and fruits it is difficult to identify a plant.

Check, Sisymbrium officinale (L.) Scop.
