Eastern India

There are 70 odd reported Chalcolithic and Iron Age black and red ware sites in West Bengal distributed mostly in the area to the west of the Bhagirathi. The most impressive evidence of crops has occurred in the Chalcolithic context at Senuar-rice, barley, wheat, sorghum, millet, peas, lentil, sesamum and linseed. From approx the middle of the third millennium BC there were fully agricultural and pre-metallic villages with a wide range of crops on the river banks of a substantial area of Bihar. The relevant cultural material in Pandu Rajar Dhibi West Bengal consists of microliths blades and husk impressions of rice in the core of pottery. In Chirand, Bihar extensive evidence has been found in form of pottery, terracotta, bone tools, beads and remains of wheat, barley and rice. At Senuar in the Kaimur foothills three principal ceramic types were found. In addition to a rich microlithic industry there are bone tools, beads and miscellaneous stone objects, rice, barley and some millet. Rice is said to have been the principal crop.
