These crops are called vegetatively propagated crops (root crops) because they are propagated not by seeds but by root division, cutting, or cuttings, and the agricultural culture in which they are cultivated as the main crop is called root crop agricultural culture. In this agricultural culture, which originally originated in tropical forest zones, the basic agricultural method is slash-and-burn, in which the forest is cut down and burned, crops are grown for about one to three years, and then the land is abandoned. …
