Ans. In the late Vedic period, agriculture was the primary source of income, and people lived in peace. Wooden ploughshares were used for ploughing. Ploughing practises are discussed extensively in the Satapatha Brahmana. Even kings and princes were willing to work in the fields. Krishna’s brother, Balarama, is referred to as Haladhara, meaning plough wielding. Ploughing was, however, forbidden in the upper varnas until the late 1800s.
