A planting of broccoli, cabbage, or cauliflower which contracts club root fungus disease this year leave behind fungus to infect broccoli, califlower, or cabbage planted there next year. Cabbage disease club root, caused by a fungus, will infect subsequent crops in the mustard family for a period of four to five years. Fusarium root rot fungus infection will increase in beans and peas unless there is a span of two to three years between plantings on the same plot of land. For example: tomato, pepper, eggplant, and potato can be treated as a single group in a rotation.Ĭommon vegetable diseases that survive in soil and attack vegetables can be prevented by timely rotation. In a small acreage, or home garden it is often possible to rotate families of vegetables where only a few plants of each kind are planted. Sweet corn is a member of the grass family, and last, but not least, is okra which is claimed by the mallow family. The Lily family includes onion, garlic, leek, and chives. Chicory, endive, saisify, dandelion, lettuce, Jerusalem artichoke, and globe artichoke are all included in the composite family. The gourd family claims the vine crops: summer squash, winter squash, pumpkin, watermelon, cantaloupe, and cucumber. The nightshade family encompasses potato, tomato, eggplant, and pepper. Carrot, parsley, celery, and parsnip all belong to the parsley family. The mustard family has many members: cabbage, collards, brussels sprouts, kale, cauliflower, broccol, kohlrabi, rutabaga, turnip, cress, horse-radish, and radish. It is important to know that the pea or legume family includes peas and beans of all kinds.īeets, chard and spinach belong to the goosefoot family. Most of the vegetables planted in this region belong to ten distinct families. For instance, most vegetables within a given family usually fall prey to the same diseases and insects. The reason for this is that each family of vegetables has unique effects on conditions which reduce garden potential. In a rotation, vegetables are often arranged according to families so that individual vegetables from the same family do not follow each other in the rotation. Of toxic chemical residues, and imbalance of essential mineral elements. Factors which interact to reduce garden potential when rotation is not employed are: increased soilborn diseases, nematodes, and soil insects lower organic matter, more chance Rotation also describes a planting system in which the vegetable plantings are arranged in a sequence to improve soil health and produce high quality and yield from year to year. The word “rotation” describes the circular motion of a wheel or shaft. New gardeners soon learn that certain vegetables, planted year after year in the same plot, become diseased and decline in productivity. Knowledgeable vegetable growers who use correct crop rotation actually increase the productivity of their farms over many years of intensive cultivation.
