CUCUMBER BREEDING Care Disease Pests Nutritional Deficiency and Plant Nutrition

Cucumber is a heat-loving plant, but air temperature above 35 C for a long time, reduces the development of plants and crop yielding power.

The optimal temperature in the greenhouse is 25-28 C.

The minimum temperature required for cucumber binding is 15 ° C, but it is a general recommendation not to drop below 12 ° C. If production below this degree is desired, greenhouses must be heated.

The suitable humidity for the plant during the vegetation period is 70-80%. If the proportional humidity rises below 50% and above 90%, it is necessary to adjust the humidity.

PLANTING IN THE GREENHOUSE

Cucumber seedlings are prepared without waiting too long when the 4th leaf seedling planting places on the row and row between the rows of 40 x 75 cm. should be planted at distances.

Soil moisture (annealing) should be sufficient during planting of seedlings.

Planting should be done during the hours when the weather is cool.

HOEING

When the seedlings planted in the greenhouse start to develop, the first anchor should be made within a week and the second anchor should be made after a while.

When the roots begin to form in the root throat where the plant joins the soil, the throat should be filled.

PLANT NUTRITIONAL DEFICIENCIES, SYMPTOMS, REMOVAL AND FERTILIZATION IN CULTIVAR BREEDING

In case of deficiency, please use one of our products or search for the following.

To avoid deficiencies, use regularly as the first leaves are up to the sparrow beak.

In cucumber cultivation, there is a bluish green color around the veins and the edges of the leaves change to bronze. Young leaves become wavy.

The necrosis leaves turn yellowish brown and brown and dry from the edges.

The fruit is soft and the body side becomes thin.

Nitrogen deficiency in cucumber cultivation, the body is thin, hard and fibrous structure.

The leaves are usually light green in color, especially the old leaves are yellowish.

Fruits are short, light green in color and the flower is shrunken.

Iron deficiency in cucumber cultivation

characteristic symptoms are caused by the deterioration of metabolic reactions affected by iron, and the restriction of energy transfer required for growth and chlorophyll synthesis.

Iron deficiency symptoms are very typical and similar in all plants, making it easy to recognize.

In many cases, however, iron deficiency as well as deficiency of some other micronutrients (particularly zinc) may also be present, making recognition difficult.

Leaf analysis provides important clues, but it is difficult to consider as a definitive criterion in the diagnosis of iron deficiency.

Boron deficiency in cucumber cultivation

The growth points in the plant die. The young leaves are grayish brown inward curved and die quickly.

Old leaves are chlorous. Plant length becomes shorter than normal as the nodes are shortened.

Magnesium deficiency in cucumber cultivation,

on old leaves, veins and leaf edges, a thin band remains green, the other parts of the leaf yellow.

Brown spots may appear on the edges of the leaves. In pruned plants, the main body cannot absorb enough magnesium to meet the requirements of new shoots, so there is a high probability of deficiency after pruning.

Phosphorus deficiency in cucumber

The leaves become dull dark green color and small. Bronze colored spots are seen on the leaves from time to time.

They stop pale and drooping or die prematurely.

The body is short and thin.

Fruits are dull green color and bronze stained.

Brown leaf necrosis appears in the leaves of the old leaves, and the leaf stalks dry.

Manganese deficiency in cucumber cultivation

is very sensitive. Deficiency is seen as a greenish yellowish or completely yellow chlorosis in the leaves. Initially, even the thinnest veins retain their green color. Then the color of the main veins turns yellow and yellowish white.

Coffee composed of colorful stains. End leaves are almost completely white.

Growth regresses and newly emerged leaves remain small.

The type and quantity of fertilizer to be applied per decare should be based on the results of soil analysis.

When should the top fertilization begin and how much should be given?

Although it changes according to soil structure and weather conditions, it is generally appropriate to start from the first fruits. According to the development of the plant and the crop load, 20 kg. Potassium Nitrate, 16 kg. Ammonium Nitrate and 3 kg. Magnesium Nitrate should be given.

  Leaf fertilizers should be used to meet the micro element requirement of the plant.

The amount of fertilizer to be applied by drip irrigation system is proportional to the amount of water to be applied. The general recommendation is to have an average of 0.3 grams of pure NPK per liter of water.

PRUNING

Plant height 30 cm. All the fruits and seats should be cut until it is. Fruiting of the plant during this period It is necessary to ensure that the nutrients taken only spend for the development of the plant.

During the growing season, all the leaf seats formed in the plant should be taken off and the flowers on the main stem should not be touched.

  IRRIGATION

In the determination of the irrigation time, the plant is based on the foliage of the leaves and the inability to easily pick up the leaf seats; water leakage in the pit opened at the depth of the plant root between two nipples.

The drip irrigation method which is widely applied in greenhouses makes it possible to meet the daily water need of the plant on a daily basis and to make irrigation and fertilization together.

HARVEST

Harvest should be done every day with a knife, fruits should not be cut by hanging. Harvesting should be done early in the morning or in the evening during warmer periods. Harvested fruits should be collected on time. Otherwise, the fruit attitude on top will be prevented.

HANGING

Cucumbers 10-15 cm. When the length of the bottom of the plant in the future to be large enough to not choke a knot is thrown and the other is made by connecting the top hill.
