Production technology of lettuce :
Lettuce can be cultivated in soil or earthen pot. Its cultivation in this country is very limited. But there is ample opportunity to cultivate lettuce in the yard of every house. This will meet the needs of the family. One can be economically benefited by selling as well.
Cultivation time :
Although it is cultivated all year round in winter-prone countries, the seeds can be sown only in phases from October to January during the Rabi season.
The soil must be fertile, and crumbly. Land should be well prepared for light cultivation. Care should be taken to ensure that the soil does not crack when the water dries up. In order to keep the soil crumbly, an equal amount of loamy soil and organic manure should be mixed well together. The amount of organic manure should be increased in clay soils.
Varieties of lettuce:
There are different varieties of lettuce. Among these Big Boston, White Boston, Paris White, Grand Baptist, New York-515, Imperial-54, Simpson, King Crown, Queen Crown, Dark, Green, Great Lake are notable.
Sowing of seeds and saplings:
Seeds can be sown directly on the land. Again, seedlings of suitable age (one month old) have to be sown in the seedbed and planted in the main land.
In this case the distance from line to line should be 12 inches and the distance from seedling to seedling should be 8 inches.
For this 4 grams per decimal of seed is required. However, 20 grams of seed is required in the seedbed. Lettuce seeds are very small. So sand or ash should be used with seeds during sowing.
Fertilizer application of lettuce:
The amount of fertilizer required for per decimal lettuce cultivation is –
- 20 kg of dung ;
- 600 gms of khail ;
- 400 gms of urea ;
- 100 gms of TSP ;
- 100 gms of potash ;
Among these, TSP and potash fertilizers have to be mixed well with the soil at the beginning and end of dung cultivation. However, urea should be divided into two equal parts and applied in two installments (10 days old and 20 days old) and mixed with the soil.
The land should always be kept free from weeds to get the expected yield. If there is no sap in the soil, it is necessary to irrigate. Similarly, if water accumulates, drainage should be done immediately. As the tree grows, the soil has to be removed at its base. It is recommended to thin the seedlings if necessary. On the one hand, as the plants will grow properly, on the other hand, can be used.
Pest Management :
Lettuce leaves can sometimes cause ‘Fungal’ disease. Symptoms of this disease are bending of the leaves and burning of the apex of the leaves. In that case, the affected trees must be destroyed. However, it is possible to get relief from this disease by purifying the seeds and soil. Insects are very harmful to insects. They suck the sap from the leaves of the plant and eat it. This discharge releases a type of fluid from the insect, which sticks to the leaves and causes a type of black fungus called ‘sooty mold’.
For this reason, the photosynthesis of the affected part is disrupted. So they must be suppressed. However, if the number of insects is less, it is better to kill it by hand. Appropriate pesticides can be applied in appropriate doses if the infestation is high. So, vegetables should not be eaten within 15 days of spraying. For this reason, pesticides should not be used.
Harvesting of lettuce:
Lettuce leaves are suitable for consumption one month after planting. At that time it is better to uproot the whole plant, but it can be used by collecting the necessary leaves from one of the plants in the house. Its average yield per decimal is 40 kg.
