Musannaf Ibn Abi Shaybah 10358 — Crops watered by flowing water

It is narrated from Qatadah that the Prophet (peace and blessings be upon him) established the practice that on land watered by rain or by running stream water, or land that needs no watering and draws its water from the moisture of the soil, on all of these there is a full tenth; and on land irrigated by rope (and bucket) there is half a tenth.
