Cultural practices for growing vegetables

Vegetables are crops whose parts are used for food. These parts may be leaves, roots or fruits. Vegetables are used for preparing soup and salad. Some vegetables can also be eaten raw, i.e. without cooking them.

Cultural practices for growing vegetables can be divided into three: pre-planting operations, planting operations and post-planting operations.

These are the activities which must be carried out on the farm before growing or planting vegetables. These activities include choosing of the site; clearing/ stumping of the site; tilling/making of beds, ridges or mounds and harrowing.

Planting operations:

Seeds and seedlings are usually planted. In some vegetables, e.g. water-leaf, stem cuttings may also be planted. Vegetable seedlings are transplanted onto the beds at correct intervals or spacing early in the morning or late in the evening.

Post-planting operations:

These are activities which should be carried out after planting vegetable seeds, seedlings or cuttings. Post-planting activities to be carried out on vegetables include mulching; manuring; staking; thinning/supplying; weeding; control of pests and diseases; harvesting; processing, preservation and storage; and marketing.
