Which one of the following ancient towns is known for the evidence of a ploughed field from its early Harappan levels, with two sets of furrows at right angles to each other, suggesting two different crops grown together?

Archaeological excavations at Kalibangan in Rajasthan have provided significant evidence of a ploughed field dating back to the Early Harappan levels [1]. This field is considered the earliest known example of its kind globally. The field features a grid of furrows with two sets of lines intersecting at right angles: one set is closely spaced (running east-west) and the other is more widely spaced (running north-south). This specific layout suggests a mixed cropping pattern where two different crops, likely mustard and gram (pulses), were grown simultaneously in the same field [1]. While terracotta models of ploughs have been found at sites like Banawali and Cholistan, the physical evidence of the furrowed field itself is unique to Kalibangan [1]. This discovery highlights the advanced agricultural technologies and subsistence strategies employed by the Harappans [1].
