It's 9am and time for breakfast. Jhanjharia's daughter-in-law Sunita arrives at the field with food.
There's roti (home-made bread) laid out on a brass plate, vegetables and buttermilk are poured into separate bowls, and some mango pickle.
Sunita has covered her face with a scarf. "It's tradition, I keep my head and face covered in front of my father-in-law," she says.
Sunita has been married for 20 years and has three sons. "I want my sons to study so that they can find good jobs."
