He said potato has become main crop of food commodities and major source of income to the farmers.The challenge before the scientists today is to double the income of farmers in such a way that fertility of the soil improved alongwith increase in production of the crops. It was not possible with chemical fertilizers and pesticides. The only alternative with the farmers is to adopt zero budget natural farming which was successfully tested in the field," said Governor.He said green revolution led to unprecedented growth in the agriculture sector that made the country self sufficient in food grain production. Constant use of fertilizers and pesticides damaged the quality of soil making it almost barren.
