SPINACH CULTIVATION Care Disease Pests Nutritional Deficiency and Plant Nutrition

Can be grown successfully in all soils. However, acidity of the soil has a significant negative effect.

It should be preferred that the cultivars that are developed flat and harvested by hand should not be grown in clay soils.

High organic matter increases yield and quality.

Soil pH should be between 6.5-7.5 for successful spinach cultivation.

SOIL PREPARATION:

Breeding as main and secondary crops is common. In the middle of summer and late summer, sowing and then watering is not a successful practice in the production of spinach.

For this reason, release irrigation is made to the field to be planted and the soil is expected to come to the pan.

Before release, the farm manure is laid in the ground. 20-25 cm deep version is made.

After fertilization, commercial fertilizers are applied to the soil surface and mixed with crowbar and disc harrow to a depth of 8-12 cm.

In general, calculations should be made to give 10-12 nitrogen per decare, 8-10 phosphorus and potassium according to the amount in the soil. All phosphorus and potassium and half of nitrogen should be given to the soil before sowing and the other half at least one month before harvest.

OCTOBER

The well prepared annealed soil is sown with 1-1.5 kg of seed per hectare.

When sowing, the whole area is divided into two seeds. The first part is planted in one direction over the entire area. The other part is sprinkled in the direction perpendicular to the sowing direction to ensure uniformity.

In order to ensure that the seeds are mixed with the soil, they are treated with a non-crossed disco.

Then, the bolt is pulled and the soil is firmly in contact with the seed.

Seed is possible with seeder 20-25 cm between the row, 3-5 cm above the row of seed frequency is provided. Seed sowing is sown to 2-3 cm. 0.7-1 kg of seed is used per decare.

Rough grasses should be taken from time to time during cultivation.

The second half of the nitrogen we will give is given by sprinkling method in the form of nitrate after sprinkling irrigation should be done.

One of the important points is the yellowing of the leaf ends. There are three reasons for this.

1-After a period of rapid development of the encounter in the form of shock cold

2-If there is not enough nitrogen in the soil

3- In case of dehydration under high temperature conditions, these yellowing may occur. In such cases, yield decreases and quality deteriorates. The produced product becomes unmarketable.

It is important not to accelerate the growth of plants, especially in the periods when cold weather approaches.

It is a cool climate vegetable in nature.

Although they are generally resistant to colds, they are damaged by the cold when it is not covered with snow depending on the variety.

In addition, early sown spinach is more damaged than winter than late sown spinach.

Excess nitrogenous fertilization also causes the spinach to be easily damaged from the winter.

Weed creates great problems in spinach cultivation.

Weeds in the soil supplemented with nutrients can rapidly develop and suppress spinach. Therefore, weed clean fields should be preferred or selective weed medication after seed sowing, before germination should be applied.

Harvest:

Market prices are effective. If the prices are high in the first period, harvest can be started if there are 15-18 cm height and 5-6 leaves.

If the prices are low, the plant is expected to grow and the leaves gain a fleshy structure. Harvest is done with hand and knife. Cut with a knife from 2-3 cm deep of the soil.

It should not be placed in closed and airy containers to prevent heat escalation. Depending on the cultivation, harvest type and variety, 1.5-3 tons / da data can be obtained.
