What significant agricultural evidence was discovered at the Harappan site of Kalibangan?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Criss-cross plough marks in fields.
Kalibangan, located in the Hanumangarh district of Rajasthan, has yielded one of the most significant discoveries regarding Indus Valley civilization agriculture: a ploughed field belonging to the pre-Harappan period.
The field exhibits a criss-cross pattern of furrows, suggesting that the Harappans practiced mixed cropping, where two different crops were grown simultaneously in the same field. This discovery provides the earliest recorded evidence of a ploughed field in history. Additionally, the presence of wooden ploughs (implied by the marks) and evidence of various grains like barley and mustard highlight the advanced agricultural techniques utilized by the settlers of this region.
