Informal intercropping of legumes with cereals? A re-assessment of clover abundance in ancient Egyptian cereal processing by-product assemblages: archaeobotanical investigations at Khentkawes town, Giza (2300-2100 BC)

摘要

The possibility that legumes were specifically cultivated as a separate fodder crop in ancient Egypt has been inferred, usually on the basis of abundance of both legume seeds and or dung in charred macro-botanical samples, combined with a lack of wood charcoal; the implication being that a scarcity of wood led to the use of dung as fuel, and that the legumes in the assemblage derive from livestock which had been fed with cultivated fodder. The archaeobotanical remains from excavations at the Old Kingdom 'Khentkawes town' (2300-2100 (BC)) on the Giza plateau in Egypt contained an abundance of legumes, but also much wood charcoal, and preservation of many fragile and 'green' seeds and plant parts. This assemblage has led to questioning of the theory of specific fodder cultivation in Pharaonic Egypt. In this article, alternative interpretations of legume-rich assemblages of cereal processing by-products are investigated. Intercropping of legumes with cereals is one of the most widespread and effective methods of improving crop value and security, and fodder/forage quality. Analysis of this assemblage has led to a hypothesis that Trifolium sp. and other 'weeds' may well have been viewed as integral plants within ancient Egyptian cereal fields, due to an awareness of the benefits of intercropping legumes with cereals-as opposed to having been specifically cultivated as a monocrop.
