Production Technology of Lettuce
Lettuce is a popular vegetable crop, cultivated both internationally and domestically. All types, such as romaine, butterhead, and leaf lettuce, require similar production technology. Learning how to grow and harvest correctly is essential for successful cultivation.
Soil Requirements
The soil should be fertile, well-drained, and slightly acidic, with a pH of 6.0–6.8. The soil should also have a high organic matter content and adequate levels of phosphorus and potassium. Prior to planting, test the soil pH and amend it with lime if necessary.
Sowing and Spacing
Sow lettuce seeds in early spring, or in late summer for a fall harvest. Seeds should be sown about ¼–⅜ inch deep. For lettuce varieties with larger heads, sow the seeds in a row, about 8–10 inches apart. For leaf, broadcast seed and thin to 6–8 inches apart. Plant successively for a continuous harvest.
Watering and Fertilizing
Keep the soil evenly moist. It requires 1–1.5 inches of water per week. When the plants are in their vegetative growth stage, fertilize them with a balanced 10-10-10 fertilizer at the rate of 1 pound per 100 square feet.
Pest and Disease Management
Various pests, including aphids, flea beetles, and slugs, can infest lettuce crops. Control these pests with insecticides, or with natural methods such as releasing beneficial insects. Lettuce is also prone to various diseases, such as downy mildew, root rot, and leaf spots. Control diseases with fungicides or by rotation and crop diversity.
Harvesting
For head lettuce, wait until the heads are the desired size before harvesting. Cut the heads off the plant with a sharp knife, leaving about an inch of the stem attached. For leaf lettuce, pick individual leaves as needed. After harvesting, store lettuce in the refrigerator for up to a week.
