Iceberg lettuce "Larsen"
Iceberg lettuce "Larsen".
Mid-early iceberg lettuce variety. Vegetation period - 80 days. Grown for the purpose of obtaining both spring and summer and autumn crops.
The heads are large and dense, the leaves are juicy and crispy. The variety is not prone to flowering, resistant to downy mildew.
Seeds begin to germinate when the soil warms up to +4°C. After the first true leaves have formed, the seedlings are planted in a permanent place (30x30 cm).
Agricultural technology.
The best predecessors for lettuce are cabbage, potatoes, under which organic fertilizers were applied.
In autumn, ploughing or digging is carried out with the introduction of humus. Acidic soils require liming. Mineral fertilizers are applied in spring.
Seeds are sown in open ground in early April, in wide rows with row spacing of 60-70 cm. The sowing depth is 1.5-2 cm. Rolling is carried out before and after sowing.
When dense seedlings appear, thinning is performed twice: in the phase of one true leaf at a distance of 5-7 cm and 1.5 months after sowing, leaving a distance of 15-20 cm between plants.
After thinning, fertilizing is carried out with a solution of a special complex fertilizer.
Care consists in loosening row spacing and watering. Watering is carried out along the furrows, trying to avoid getting water on the leaves of plants.
Lettuce is harvested by cutting off a rosette of leaves at the very surface of the soil.
