There is a rich corpus of texts about agriculture during the Rasulid era (13th-15th centuries CE) in Yemen. One of the most important crops at the time was the date palm (nakhl), which was grown in the Tihama coastal region, Najran and Hadramawt. This essay provides a translation and analysis of the section on date palms in the 13th century agricultural treatise Milh al-malaha fi ma'rifat al-filaha, written by the Rasulid sultan al-Malik al-Ashraf 'Umar. Details are provided on the varieties of dates, their cultivation, pollination and protection from insects and diseases. ukryj opis
