Sementeira

Sown in a tray, seedlings should be transplanted to the final location 3 to 4 weeks later. The crop can be grown in rows, with 15 to 20 cm between plants and 45 to 60 cm between rows.

Solo

It is a crop that adapts well to different soil types, though it is essential that they have good drainage capacity. Soil pH should be between 5.5 and 7.

Clima

The crop prefers temperatures between 20 and 30°C; however, temperatures should not be extreme, as this will lead to premature bolting.

Fertilização

Compost should be incorporated as a base fertilizer to meet the crop's nutritional needs. It is important that the soil has adequate phosphorus at the start of development; if sufficient levels are not present in the soil or through the addition of compost, a mineral fertilizer rich in this nutrient should be applied.

Rega

Watering should be done regularly, as the root system is not very deep. Drip irrigation is particularly well suited for lettuce cultivation, as it prevents excessive moisture on the leaves and thus reduces the risk of disease.

Controlo de Infestantes

Mulching is an interesting option for lettuce cultivation, reducing competition between weeds and the crop.

Controlo de Pragas

Mites, aphids, leaf-mining larvae and root-knot nematodes are pests of this crop. Mites can be managed through biological control with predatory mites and, if necessary, by applying azadirachtin or sulphur dust (if T < 28°C). Aphids can be controlled through moderate fertilisation without excess nitrogen, natural limitation using hedgerows along field borders to support beneficial insects, biological control with parasitoid and predatory hymenopterans, and, if necessary, the application of potassium soap or azadirachtin. Leaf-mining larvae can be managed through natural limitation using hedgerows and other vegetation with nectar-rich plants to feed adult parasitoids, biological control with parasitoid hymenopterans, and, as a supplementary measure, the application of azadirachtin. Root-knot nematodes are controlled through crop rotations, biofumigation and soil solarisation.

Doenças

Alternaria blight, Sclerotinia, downy mildew and grey rot are diseases that affect this crop. To control Alternaria blight, wide plant spacing and copper-based fungicides (such as Bordeaux mixture) should be used. To control Sclerotinia, appropriate crop rotations and wider spacing should be carried out, and infected plants should be removed from the ground as early as possible. Downy mildew can be controlled through crop rotations of at least 3 years, avoiding excess water in the soil and humidity in the air, using wide spacing and, if necessary, applying copper hydroxide at reduced concentrations (which should be lower the colder the weather, as it may risk scorching the leaves). Finally, grey rot should be controlled by removing diseased plant debris, avoiding excessive vigour, keeping water off the plants and through regular application of bentonite clay.
