Lettuce

Lettuce (Lactuca sativa) is an annual leaf vegetable of the aster family (Asteraceae), originated in the Middle East. Lettuce is generally a rich source of vitamins K and A, though the nutritional quality varies, depending on the variety.                                                                      

Lettuce yields can reach up to 50-70 tons/hectare, depending on the species, the number of growth cycles, and soil conditions. It is usually harvested before the flowering phase, as the bolting of the flower stalk elongates the lettuce head, reduces the leaves' size, and imparts a bitter flavor to the crop.                                                                                                                    

The lettuce plant is best suited to a moderate climate, with temperatures of 13-16 °C (temperatures of 7-24 °C for germination). Short days are ideal for growing lettuce. Days lasting longer than 12 hours cause the lettuce to bloom. Lettuce's growth period may last 60-90 days in the autumn and 21-30 days during the summer.

Farmers Pain Points

Climate: Lettuce is sensitive to frost on one hand and might suffer from very high temperature conditions on the other hand. If you have any of them, you will need a proper solution.
 

Growing cycle is relatively short therefore irrigation and fertigation must be accurate (no time for corrections).
 

Insecticides: A proper weeds control system is essential for achieving high yield.
 

Fungicides: Due to the form of lettuce and the high density of plants in the plot, humidity driven diseases must be controlled properly.
 

Soil Disinfection: Soil diseases may cause a lot of damage, controlling/ coping with those diseases is critical.
 

Post-harvest: After harvest, lettuce must be packed quickly and correctly in order for it to arrive fresh to the market.
