The term “Asian crucifers” is a broad category that encompasses Asian crucifer vegetables grown in the countries that comprise Asia and those eaten mainly by people of Asian extraction or who like Asian cuisine. Because many of the Asian crucifers described in this chapter belong to the crucifer family, which is covered in depth in chapter 5, “Ethnic Vegetable Production,” that information will not be duplicated elsewhere. However, there are still some overlaps between these two chapters.
This group of Asian crucifer vegetable species include crops with edible leaves, like cabbage, broccoli, and bok choi, but also kohlrabi, which has edible swollen stems or tubers, and daikon, which is an edible root. These crops can be grown on raised beds with or without mulch and with drip, overhead, or subsurface irrigation. Fertilizer recommendations for these crops can be found in chapter 2, “Fertilizer Management for Vegetable Production in Florida,” as general information. For pest-control products, these crops are included under this chapter, with the exception of daikon, for which refer to information on radish in chapter 15, “Root Crop Production in Florida.”
