Ибн Хордадбех
Oats, rye, and millet were also grown for use as fodder in the Sawad. Ibn Wahshiyya recorded the nahiyahs of "Saqī dijla", "Asfal iqlīm Bābil", "Jūkhī", and "al-Jarāmiqa" as producing these crops in large quantities. Ibn Khordadbeh wrote that, in the Rustuqbadh district, millet was used alongside barley to pay taxes, indicating its local importance. Alfalfa and clover were also grown as fodder as well as to replenish soils, but their importance appears to have declined after the second century AH.
