What is the prescribed Zakat on land distributed among heirs that is cultivated with beets, flax, cotton, wheat, and rice, in addition to leased land?

Scholars differ on what produce from the land is subject to zakat. Abu Hanifa held that zakat is obligatory on all produce from the earth, including grains, fruits, vegetables, legumes, and flowers, citing the general import of the Prophet's ﷺ saying: "On what is irrigated by the sky and springs or by natural irrigation (athari) is a tenth, and on what is irrigated by watering camels (nadh) is half a tenth." Whereas the three Imams held that it is obligatory on what is measurable by volume and staple food, such as wheat, rice, dates, and raisins, citing the Prophet's ﷺ saying: "There is no sadaqa (zakat) on less than five wasqs of dates or grain."

Accordingly, zakat is obligatory on wheat and rice if they reach the nisaab (five wasqs), and it is to be paid at harvest time, based on the Almighty's saying: "And give its due on the day of its harvest" (Quran 6:141). As for other crops, zakat is obligatory on their monetary value if it reaches the nisaab and a year has passed since its acquisition. The nisaab for cultivation is five wasqs (three hundred sa's), and half a tenth is to be paid if irrigated by watering camels (nadh), and a tenth if irrigated by other means. Zakat is obligatory on any partner who acquires a nisaab. There is no zakat on leased land itself, but zakat is obligatory on its rent if it reaches the nisaab and a year has passed since its acquisition.
