    Field test results showed that the harvester could cut and lift the lettuce heads without damaging and blemishing the produce at working speed of m/s and the commercial head percentage was %. At higher working speed of m/s, the head damage rate was % reducing the percent of commercially accepted heads to %.   Harvest loose leaf lettuce as needed, preferably before bolting. For large-scale planting, sort the heads in the field and pack immediately in perforated carton boxes. If available, vacuum cooling at 1oC is best. Transport at 4 o C. Lettuce is the most important salad crop grown in most homes and school gardens throughout the country.

    open-field and greenhouse farming systems to socio-economic and climate risks. It is believed that greenhouse crop production is destined to play an increasingly important role in the Mediterranean climate environment as a means for sustainable crop intensification leading to optimization of water-use efficiency in an environment.   Wild lettuce (Lactuca virosa) is native to many areas of the world, including North America, Europe and the Middle herb thrives in .

      A Japanese company is to open the world’s first “robot farm”, as agriculture joins other sectors of the economy in attempting to fill labour shortages created by the country’s rapidly.   If you greenhouse field crops and micro greens this number could be higher. Sell 50 flats of micros per week at $20 a flat, it would be possible to gross $58, from this size plot. The risk in this model is that your crops will be highly specialized and be relying on a small number of clients.

Transplants should be planted near the last frost-free date for the growing area. Seeded lettuce may be planted 2 to 3 weeks earlier. For either seeded or transplanted lettuce, have 12 to 15 inches between each row. Leaf lettuce: Plant 4 inches apart.

Cos and loose-headed types: Plant 8 inches apart. Firm-headed types: Plant 16 inches apart. technologies that can be used in the packinghouse, be it a simple shed in the field or a separate structure with cooling and storage facilities.

Small Scale Postharvest Handling Practices: A Manual for Horticultural Crops (4 th edition). Lettuce is adapted to cool growing conditions with the optimum temperatures for growth of 60 to 65°F.

At 70 to 80°F, the plants flower and produce seed. Lettuce can tolerate a few days of temperatures from 80 to 85°F, provided that nights are cool. Lettuce seed will germinate at 35°F, but optimum germination is 70 to 75°F.Choose Auto-crop to trim all the white margins automatically.
