Crops and agriculture during the Iron Age and late antiquity in Cerdanyola del Vallès (Catalonia, Spain)

Various sites in the valley of the Sant Cugat stream in Cerdanyola del Vallès (Catalonia) were subject to systematic archaeobotanical sampling to obtain an overview of the crops and agriculture of the area during the Iron Age and late antiquity. In all cases, the most numerous taxa were crop plants. Among these, cereals were clearly predominant at all sites investigated, especially Hordeum vulgare var. vulgare (hulled barley) and Triticum aestivum/durum (bread or macaroni wheat), both in numbers and frequency. Other cereals, such as Triticum dicoccum (emmer) or Setaria italica (foxtail bristle-grass), were regularly present in considerably lower numbers but in fairly high frequencies. Pulses were much less numerous, although their presence increases in terms of frequency. Among them, clearly the best represented was Lens culinaris (lentil). The results show that the agriculture in the period considered was principally based on winter cereals, with a gradual substitution of hulled barley by bread/hard wheat, accompanied by other cereals of minor importance, led by Triticum dicoccum (emmer), and pulses. The appearance of Vitis (grapevine) in the Iberian period is one of the important characteristics of agriculture in the Iberian world.
