Agricultural activity is considered one of the important economic activities on which the Arab economy depends to a large extent, and most of the Arab Islamic lands were agricultural lands, including the most fertile and productive lands in the world, and abundant in water.Andalusia was one of these lands, and its agriculture developed under Arab rule, and became a paradise, and this is what the researchers reached during their study of "Agriculture and Irrigation in the Era of the Caliphate and the Emirate". The first sources of Andalusia were taken from Eastern sources, as many Eastern books conveyed the experiences of Andalusia in agriculture and irrigation. Andalusian scholars also paid great attention to agriculture, so they wrote many books that dealt with the various branches of botany. They provided farmers with advice and guidance on what is correct and serves and develops agricultural work. The study dealt with research on the means of agricultural production and irrigation methods in Andalusia in the era of the Emirate (138-316 AH / 756-929 AD).
