The discovery of a ploughed field with grid-patterned furrow marks in association with the pre-Harappa levels at KALIBANGAN (already referred to earlier) makes it amply clear that these people had even planned to produce two kinds of cereals simultaneously in a single field. In other words, agricultural surplus—an imperative for sustaining urban centres wherein whole-time craft-specialists depend on food-supply from rural areas—was being created. Though no doubt not on the Harappa scale, trade and commerce were also in evidence; otherwise how else can one explain the presence of lapis lazuli, which very likely was an import from Afghanistan, in the pre-Harappa levels? - [Previous: v1.c9.s9.58](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c9.s9.58) - [Next: v1.c9.s9.60](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c9.s9.60) - [Up: v1.c9.s9](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c9.s9) ## Linked texts (1) - [Kālībangan](https://indike.org/pramana/inp.site.kalibangan) --- Source: [https://indike.org/pramana/ins.reference.ghosh-1989.v1.c9.s9.59](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c9.s9.59) · Pramāṇa
