LEAK CULTIVATION Care Disease Pests Nutritional Deficiency and Plant Nutrition

Leek has a very dense root structure. The trunk lies between the roots and the axle and the leaves are arranged on it.

Yapraques are formed on this body from outside to inside.

The oldest leaf is the outermost leaf.

In the leeks, the flowers are arranged in the shape of a star like a bulb at the end of a bunch of flowers which can take up to 2 m in length in the spring of the 2nd year. Seeds germinate under normal conditions 12-15 days.

Germination occurs at 10-35 ° C. They keep germination power for 2-3 years


It is a cool climate vegetable. Does not like extreme heat and drought in this case yield and quality is reduced.

The optimum development temperature is 15-20 ° C.

Depending on the occurrence of low temperatures gradually depending on the formation of winter or summer leek varieties, there are winter varieties that last up to -18 ° C. Leeks are a long day plant.


Leeks are not selective in terms of soil requirements. The most successful results in loamy-clay soils.

It is very successful in growing soils rich in organic nutrients. Nitrogen is the most needed nutrient and most effective in yield.

The plant requires less phosphorus and potassium. Giving nitrogen fertilizer several times increases the success.

Both yield and quality increase in aquaculture in soils with high water holding capacity. The optimum soil pH is 6.0 - 6.5.


Leek is a two-year vegetable when it is produced to buy seeds. In the first year, the plant remains vegetative. In the second year forms flower seeds. Produced with leek seeds. There are two different production methods.


Leeks can be produced directly by sowing seed, but production is largely done by first producing seedlings in pans and then planting these seedlings in their original locations. 10-15 days after planting plants are seen on the soil.

After the germination is completed, dilution is done in such a way that there is a plant at 12-15 cm. 200-300 gr of seed is used for direct sowing of 1 decare area.


For seedling production, the seedlings should be grown as needed for planting in time. Sowing is done on pans 50-70 days before the planting date.

Leek seedlings will be grown 1-2 months before planting with burned farm manure to fertilize 4-5 tons of fertilizer per hectare.

This fertilizer is mixed with the soil to a depth of 15-20 cm and the pans of 120 cm width are prepared according to the slope in the field.

Sowing is done by spreading these pans. The seed to be sown is divided into at least two in the same pan transverse and longitudinal in two times, three is divided into three times. If there is the possibility of preparing mortar on top of the pans until the beginning of germination after the planting with the mortar is shaded with bushes and twigs.

In October, 10-12 g of seeds are thrown on 1 m2 area. For 50.000 seedlings, 300 g seed 25 m2 pan is required.

If planting is to be done at 30x12 cm intervals, approximately 28-30 thousand seedlings per decare are required. Accordingly, seedling preparation should be done.

Seedling development period of regular weed and in the early period of frequent dilution of the seedlings by making a slight homogeneous development of the equivalent is provided.

The applications to be done for weed control after planting are important for aquaculture. After fertilization, as in cultivation with seed, the furrows are opened at a depth of 20-25 cm and 30-40 cm intervals. Planting is done by giving water into furrows.

Seedlings prepared by shearing 1/3 of their leaves and long roots (shaved) and divided into 2-3 size groups are planted in the furrows of each group in a separate parcel. Care is taken not to make deep sewing. Row spacing may vary between 10-14 cm.


After planting seedlings begin to develop by rooting. During this period, an anchor is made carefully for once. For the planting of 1 decare, 4-5 workforce is required for horticulture and 5-7 wage labor. In fact, the most important cost element in leek planting, hoeing and dismantling labor.

After hoeing, half of the nitrogenous fertilizer that we have separated is divided into two and given to the plants in order not to touch the furrows in intervals of 2 weeks and the plants are watered regularly until they reach the harvest size.


Harvest can be done in almost every period of development in Leek. Harvest time is determined by the market conditions and the grower's decision. In order to obtain normal yield, leeks should be harvested until the period in which 120-150 g or more weight is gained.

However, if a high price has been established in the market, harvesting can be started earlier. Harvest can be done by hand or by plow removal. Both leeks removed from the soil immediately in the field leeks cleaned and the roots are cleaned not to exceed 1 cm in length.

Also the last leaf on the axle is taken. It is shaved at 1/3 of the leaf blades and marketed by being bundled.
