Leek, which ranks first in the group of winter vegetables in our country, is a biennial vegetable. In the first year, the edible long-leaved stem is formed, in the second year it blooms and sets seed. Leeks are mainly consumed by cooking. Since it belongs to the same family as the onion, it has many common characteristics, but it does not grow heads and the part that is eaten is the stem and leaves. It constitutes an important part of vegetable production in regions with a continental climate. SOIL REQUIREMENT Although leeks can be grown in any soil, moist, humus and nutrient-rich loamy-clay soils are ideal. Increasing humus in the soil improves quality. Soil pH should be around 6-6,5. Acidic soils should be avoided in leek cultivation. Nitrogen should not be deficient in terms of nutrients in the soil. A second irrigation should be done 3-4 days after the first watering. If there is no rain about 10 days after the second irrigation, a third irrigation and irrigation with an interval of 1-2 weeks during the whole development period according to the weather conditions is the most important thing for the leek to develop as desired. After irrigations, hoeing for soil aeration and weed control can be counted among the maintenance works in the field.
