POTATO GROWING Care Disease Pests Nutritional Deficiency and Plant Nutrition

It depends on the structure of the soil and the plant grown before the potato. A rapid ascent, strong root development and good soil preparation are needed for the development of the tubers. In heavy (clayey) soils, in the fall 20-25 cm. depth version is made.

In spring, disc harrow and rake are passed. In light (sandy) soils in spring, so as not to loosen the soil is more concentrated version.

Only by pulling a rake, the seed bed is prepared.


Potato is a plant that needs more care. It is useful to pull a corrected (toothed) rake before exiting.

If the soil is tied to the cream layer, it will be broken and the newly weeds will be killed.

When the potatoes have 3-4 leaves, they are exposed and carefully made on the first anchor.

With this anchor, the soil is raised, weeds are killed and moisture is maintained.

Thereafter, the throat filling process is performed with each anchor at an interval of 20 days (3-4 times if necessary).


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.

There are significant differences between the varieties of zinc deficiency in potato cultivation in terms of sensitivity to zinc deficiency.

Growth is very weak.

The leaves deform and are covered with grayish brown or bronze stains.

These images are more dominant in young leaves. Leaf palms often thicken.

If deficiency is severe, leaves fall and eventually the plant dies.

Potato breeding in potassium deficiency

The leaves are metallic bronze color on dark green. The plant becomes dwarf and bushy.

Old leaves get color at the edges.

In leaf leaf beginning, brown colored spots are seen as the size of a pinhead, which then grows to cover the leaf surface.

Curls are seen on the leaves.

Black dots are formed on the potato tubers.

Potassium deficiency can also cause browning in the inside of the tuber, but care should be taken not to confuse it with the problem called brown essence due to boron deficiency.

Potassium deficiency causes a decrease in the amount of dry matter and starch in the potato tuber and also after darkening within a short period of one hour after the discontinuation of the potash-deficient tubers, even in the tubers of plants with full potassium feeding, such a situation is not seen even after two days.

Nitrogen deficiency in potato cultivation

the first signs are seen in the old leaves at the bottom.

The lower leaves of the plant first turn to pale green color and then turn yellowish green color. In the advanced stages, these yellowings progress from lower leaves to upper leaves.

In some cases, leaves that are deficient can show curl and blotches.

The bodies become thin and form a hard structure.

In plants with nitrogen deficiency, shorter plants appear to have a stunted appearance.

In the excess nitrogen, the leaves are coarser and coarse, the color of the leaves is dark green.

  Due to the excess nitrogen, the resistance of plants to cold decreases.

Boron deficiency in potato cultivation

plant height becomes shorter, side branching increases, the plant takes a bushy image.

The leaves are thick and crisp, and in some cases the edges are curled inward.

Leaf petioles flatten. Young leaves and growth points initially become dark green, then chlorosis develops and dies.

Necrosis in the form of brown spots on the edges of the leaflets, which then combine to grow.

If boron deficiency is removed at this stage, new exiles will emerge.

 In case of deficiency, the old leaves turn yellow and fade.

The round annular veins in the tuber turn brown.

The shell is dark colored and has a rough structure.

Due to the formation of melanin, the cut surfaces quickly turn reddish dark brown

IIron deficiency in potato cultivation

A very typical feature is that the younger the leaves, the more severe the symptoms are.

Unlike other nutrient deficiencies, a typical feature of iron deficiency is that the chlorinated leaves remain viable without readily dying.

However, if the deficiency is very, very severe, the leaves may also die.

 The characteristic symptoms of iron deficiency are due to the deterioration of the metabolic reactions affected by iron, and the restriction of energy transfer necessary for growth and chlorophyll synthesis.

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

However, in many cases iron deficiency as well as other deficiencies of some micronutrients (especially zinc) may also occur, making it difficult to recognize.

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

Magnesium deficiency in potato cultivation,

Symptoms are seen on the old leaves.

The vein of the leaves is reduced green color between them.

It is seen as yellowish green and then brown spots like potassium.

  Magnesium deficiency of the leaf, starting from the leaf stalk to the end of the leaf advances, at the same time starting from the middle vein to the edge of the leaf color changes are seen.

This is the exact opposite of potassium deficiency.

Magnesium deficiency occurs especially in very sandy soils and in the use of extremely unburned animal manure.

In magnesium deficiency, the vessels remain green and in the deficiency of potassium, they turn yellow and dry in the veins.

This is a characteristic feature to distinguish between the two elements' deficiency symptoms.

Phosphorus deficiency in potato cultivation,

The leaf system is hard and upright.

Growth in the plant regresses and a dwarf body is formed.

Especially the old leaves curl up and then necrotic lesions occur on the edges of the leaves.

The leaves are smaller than normal.

The old leaf turns brown and casts early.

Sometimes there are brown spots on the tubers.

Potato manganese deficiency

the youngest leaves are light colored and pale.

The color of the young leaves leaves between the veins and chlorosis emerges, followed by spots in the form of numerous brown spots.

The stains are mostly collected around the main vein, and their number increases towards the leaf stem.

The plant remains scrub.

Calcium deficiency in potato growing

plant's top (end) leaves show signs of deficiency.

The leaves shrink and curl inside.

Leaf color turns light green and then very light yellow - white color.

The top bud dies blunt and the plant does not grow in length.

Potato tubers are very deformed.

Important note:

Always use Wet spreader glue if your irrigation or spray water has a pH of 8 - 8.5 every time you spray your garden. (Soil and water pH in many regions of our country is up to 8- 8.5 or even up to 9.) All drugs produced are produced according to the pH range of 6-7. Even the best quality medicines lose their effect by up to 30%, from 6 to 15 minutes. Buddha will reduce the effect of your medicine.

For this reason, our advice to your holder, tank or back pump,


1 PH DECREASING ADHESIVE  It reduces the pH of the spraying water and prevents the deterioration of the drug. Once the medicines are applied to the plant, it allows the drug to spread to the leaf and prevents it from flowing through the leaves.
2 PLANT FOOD Provides smooth and balanced nutrition of the plant. It makes the fruits attractive, bright, colorful, large, durable, hard, heavy, tasty and pleasantly fragrant.
3 INSECTICIDES Use a medicine against pests at the bottom of the page, according to the pest period. Pay attention to the duration of harvesting - use of medicines.
4 FUNGUSİT MUSHROOM (After mixing in a separate container) Use a medicine against pests at the bottom of the page, depending on the disease period. Pay attention to the duration of harvesting - use of medicines.
5 OTHER Other trace elements recommended by technical staff.  

Try to use all of them as much as possible, reducing costs.

LIME SOLVENT It should be used in calcareous soils at the beginning of the season. Lime wrapped around capillary roots destroys the creamy layer. Soil bound iron, phosphorus and phosphates are released in the soil, the plant uses them. you do not need to use iron and phosphorus fertilizers repeatedly. 1 Kg drip irrigation per hectare
PLANT FOOD First application before flowering,
second application in fruit attitude,
The third application is done 45 days before harvest
Two applications with 300 gr / 100 lt water in all periods required.
200-300 cc
ZINC Apply when eyes explode and flowering is over. The most important time to apply the fruit is collected (before the leaves fall yet) configure. It allows the accumulation of zinc in the eyes of next spring and healthy new shoots. 125-150 cc
DRIP IRRIGATION NITROGEN, PHOSPHORUS, BALANCED, POTASSIUM It should be used regularly every semester. NPK of the plant must be met 2-3 kg
ORGANIC Organic based drip irrigation and release irrigation fertilizer. Fifteen days apart. One empty, one full watering or split quantities full watering Dönüme
5-7 kg

Foliar fertilizer should be used in every application. Leaf fertilizers prevent plants from getting stressed. It meets the micro element needs of plants. Improves fruit set and quality of fruits.

When planted one after the other, the diseases multiply and the yield decreases.

Legumes and cereals, which provide nitrogen and humus to the soil, are particularly suitable for the rotation of winter cereals.


Part of the potato we use as seed tubers.

Seed tubers should be 6 cm in diameter and weigh an average of 50 grams.

The type of seed should be selected according to the production purpose.

Certified seed should be used.

Seed tubers should be awakened during planting and have green shoots about 1 cm tall.


Potatoes are planted in spring when the soil temperature reaches 8-10 oC and late frosts end.

Between planting 70-75 cm row, the row is 20 sıra40 cm. Planting depth; It is 2 cm in planting and 5 cm in deep planting.

At least 15 cm soil should be placed on top of the planting and 10 cm soil should be placed on deep planted ridge. Backing time;

Immediately after planting, in low temperature or soil tying conditions, ridge is made when the output is complete.

If high temperatures and drought are expected after planting, ridge is done immediately after planting. Planting is done manually or by machine. The most suitable method of planting;

Seed tubers placed in furrow bottoms opened with furrow plow,

It is the closure of furrows through the ridges of the same furrow plow.

Throat filling and weed control can also be done with the same furrow plow when the plants reach the appropriate size after emergence.

200-250 kg per decare in wet conditions, 150 kg of seed is sufficient in dry conditions.


The need for water in potato plants is manifested by fading and yellowing in the lower leaves.

Taking into account the moisture in the soil, the first irrigation should be done when the tubers reach the size of the nuts.

In light soils 15-18, in heavy soils 22-25 days apart, 2-4 irrigation during cultivation is done. Leave a period of 1 week between harvest and last watering.

The most common method of irrigation is furrow irrigation. The distance between two furrows is 60-65cm in sandy soils and 70-80cmm in heavy soils.

The period in which potatoes need the most water is the period that begins 20 days before flowering and lasts until the tuber starts to make.

If watering is not done adequately and regularly, mammalian and cracked tubers, blackening and cavities occur in the tuber, especially yield loss.

It is understood that the leaves and stalks, which are the time of harvest in the potato, turn yellow and dry, the tubers are easily separated from the plant by taking the normal size and the shell thickens and hardens.

The shell is not easily peeled off with nails.

The cross section of the tuber is not wet but dark.

It is necessary to be very careful in harvesting potatoes.

Tubers should not be cut and damaged; It is the property. During dismantling, the soil should not be wet and should be annealed.

Potato harvest is done in different ways:

Potatoes are removed by hand with waist, fork or anchor and collected by hand.

It is disassembled with a plow and collected by hand.

If the tubers are wet after harvest, they are dried in the shade.

Sick, bruised, bruised and peeled ones are extracted.

Then they are classified into coarse, medium and small size and filled into mesh sacks.


Potato is a product that contains a large amount of water because it is damaged if not stored well.

Tubers rots, purses, sprouts and loses its value.

Tubers in the best way; mature, undamaged and clean at 3-40C temperature, 85-90% relative humidity and respiration as a result of carbon dioxide, water and heat to provide oxygen to provide good ventilation equipment can be stored in special protection stores.

The heap height in storage can be 3-4 meters in edible potatoes.

Seed potatoes should be at most 1 meter.
