The Indus script possessed a set of signs referring to crop and share of the agricultural produce (Chart I). Five hierarchical levels of levies on the produce have been identified, namely, those due to god, state, city, land owner, and the tenant-farmer. Survivals of the agricultural signs in the Indus script as pottery graffiti in later periods are illustrated in Chart II. A list of signs of the Indus script depicting agricultural implements is also included (Chart III).
