Land Preparation

Plough land for two-three times and bring soil to fine tilth. Carry out soil testing to check nutritional status of soil. If soil is deficient in nutrients apply micro-nutrients on basis of soil test results.

Time of sowing

Prepare nursery in the month of mid-September to mid-November. Sow seeds in nursery at a distance of 15-20 cm. It takes 3-4 days for germination of seeds. After germinations, lettuce required sunlight for minimum 3-4 hours per day in morning. When seedlings become four to six weeks old, transplant them into main field.


When seedlings are transplanted in main field, use row to row spacing of 45 cm and plant to plant distance of 30 cm.

Sowing Depth

Depth should be 2-4 cm.

Method of Sowing

For sowing of lettuce use transplanting method.

Seed Rate

To raise seedlings for 1 acre, sow 400gm seeds in 2 marla. Irrigate nursery beds at interval of week.

Fertilizer Requirement (kg/acre)

Apply well decomposed cow dung@15 ton per acre, and Nitrogen@25 kg (in form of Urea@55 kg), Phosphorus@12 kg (in form of Super Phosphate@75 kg) per acre. Apply whole amount of phosphorus and half amount of nitrogen before transplantation. Give remaining amount of nitrogen six weeks after transplantation.


48 hours before transplantation stop irrigating nursery beds. 30 minutes before transplantation apply good amount of irrigation. It will help in easy pulling of seedlings. Provide first irrigation, immediately after transplantation. Apply remaining irrigation, at interval of 5-6 days on light soils whereas 8 to 10 days irrigation interval for heavy soils.
