LITERATURE REVIEW
Lettuce is the temperature annual or biennial plants of the daisy family Asteracease or it is also a cultivated plant of the daisy family, with edible leaves they area usual ingredient of salads. It is most often grown as a leaf vegetable. It is eaten either raw, notably in salads, sandwiches, hamburgers, tacos, and many other dishes, or cooked as in Chinese cuisine in which the stem become just as important as the leaf. Lettuce is one of those crops whose fresh picked taste simply can’t be equalled by anything you can buy at the grocers.
Successful production of lettuce depends on the vigorous growth. A wide range of well-drained soil can be used, however, the crop does best on fertile, high organic matter soil that have good water holding capacity.
Lettuce is attacked by aphids, armyworms, imported cabbage worm, and loopers. The pest pressure on summer and full crops is much greater than on spring crops.
The lettuce plant has a very short stem initially ( a rosette grown habit), but when it gradually blooms, the stem and branches lengthen and produce many flower heads that look like those of dandelions, but smaller. This is referred to obsoleting. When grown to ear. Lettuce is harvested before it bolts. Lettuce is used as a food plant by the larvae of some Lepidoptera.
For head lettuce, row 30 to 42 inches apart are common. Regardless of the row width, the in row spacing between each head lettuce plant should be 12 inches. If 42-inches row are used, yield can be increase by planting 2 seed rows per bed leaf and butter head types should be grown in double rows 12 inches apart and 8 to 10 inches in row spacing.
The head lettuce will be ready for harvesting in 70 to 80 days after seeding or 60 to 70 days after transplanting cut only those heads that are firm. Leave 3 to 4 “wrapper” leaves to protest the head. Most leaf types are ready in 50 to 60 days after seeding to 30 to 45 days after transplanting. You will have to harvest
