NEW DELHI : Desi 'kaadha' and lemonade have become the most consumed beverages among farmers protesting against the new Central agricultural laws at three Delhi borders for nearly six months now, even as the raging coronavirus pandemic claims hundreds of lives daily and leaves thousands sick.They have also added multi-vitamin and zinc tablets as supplements hoping to improve their immunity against the virus, but are resolved not to yield ground until their demands -- a repeal of the three contentious farm laws and a new one guaranteeing MSP on crops -- are met.But, they say, they are open to COVID-19 vaccine jabs.Hundreds of farmers, chiefly from Punjab, Haryana and Uttar Pradesh, continue to encamp Singhu, Tikri and Ghazipur border points.
