Lettuce Cultivation On this occasion we will show all of you information about Lettuce Cultivation. Pay attention to the information we convey below for your knowledge in cultivation. Hopefully it can be useful and as motivation for you in trying.
lettuce is a plant that is cultivated in lowland areas. Leaf lettuce has leaves that are fresh green in color, have jagged or wavy edges, and are more delicious eaten raw. Lettuce is often used as a friend to eat, namely as fresh vegetables. Lettuce is fresh green and some is red. Apart from being a vegetable, this slightly curly lettuce is often used to decorate dishes.
Lettuce grown in the lowlands tends to flower and seed faster. The optimal temperature for lettuce growth is between 15-25 ° C. The types of soil that are preferred by lettuce are dusty loam, sandy loam, and soil that still contains humus. However, lettuce is still tolerant of nutrient-poor soils provided adequate irrigation and organic fertilizers are provided. The soil should react neutrally. If the soil is acidic, the lettuce leaves turn yellow. Therefore, for acidic soils, liming should be done before planting.
Lettuce seeds are propagated by seeds. The small seeds are obtained from plants that are allowed to flower and prosper. After the soil smells, the plants are picked and the seeds are taken. However, now lettuce seeds are widely sold in farm shops. Especially for lettuce seeds, superior seeds are better bought at the store. It is intended that the production and quality of production will remain excellent. For one hectare of land it is expected about 250 g of seed. Usually lettuce seeds are sown first: Direct planting can be done, but it is better if sown first. Seeding can be done in a box or in the field. When on land, do the tillage until it is loose. Add sand and manure. Sow the seeds evenly. Then cover with a thin layer of soil. After about 3 weeks the seedlings are ready to be transferred to the field. Planting The land to be planted is processed first. The soil is hoeed to a depth of 20 cm. Small and large stones are removed from the field. hardened or cracked soil is crushed. This is important because the small, shallow roots of lettuce plants are difficult to penetrate the hard soil layer. Lettuce is grown in beds. The width of the beds is 1-1.2 m with a height of about 20 cm above the ground. The length of the beds is adjusted to the conditions of the land. Between the beds a small ditch is formed to regulate the excess or lack of water. Medium spacing used is 20 x 25 cm.
Maintenance When the plant is 2 weeks old, weeding must be done. This is because the lettuce roots are shallow so they are less able to compete with other plants in absorbing nutrients. Weeding also serves to suppress pests and diseases. The working interval is once a week. Watering in lettuce plants deserves attention. Especially in the lowlands where the air is hotter and there is often a shortage of water. Water needs are absolutely met at the beginning of planting, during the first weeding (2 weeks old), and when the plants are a month old. If it does not rain, do watering with a drill or pass water through the irrigation ditch. Also take care that the irrigation ditch can pass excess water when it rains heavily. Fertilization The need for manure for lettuce is 10 tons/ha. This fertilizer is mixed on the surface of the planting area. In addition to manure pvpuk, also add chemical fertilizers, especially urea. The doses given are Urea 200 kg, TSP 100 kg, and KCI 100 kg per hectare. Fertilizer is given in grooves on the left and right of the plant. It is given at the time of planting.
Pests and Diseases
Lettuce plants are often the target of aphids. As a result of this pest attack the leaves shrivel and dry up due to lack of water. If young plants are attacked then plant growth is not right or stunted. Insecticides commonly used to control ticks include Diazinon; Bayrusil, or Orthene 75 SP. Spray with a dose of 2 cc / l of water. Thrips are quite a concern for lettuce farmers. The characteristics of thrips attack are yellowing leaves, drying out, and finally the plant dies. This pest can be controlled with Tamarot 200 EC, Bayrusil 250 EC, or Tokuthion 500 EC with a dose of 2 ml / l of water. The disease that is often found in lettuce is stem fish. Symptoms are characterized by softened and slimy stems. The cause is the fungus Rhizoctonia solani. When it attacks plants in the nursery, it often causes fishy roots. When the condition of the land is watery, disease attacks can intensify. For prevention, the cleanliness of the land must be maintained and the humidity of the land is reduced.
