BANANA BREEDING Care Disease Pests Nutritional Deficiency and Plant Nutrition

Banana is a tropical climate plant. Annual average temperature above 20 C, annual temperature difference does not exceed 4-5 C micro air conditioning, grows in humid places.

The annual rainfall should be between 1000-2000 mm. Irrigation should be done in cases where sufficient rainfall is not obtained. Humidity should be above 60%. Saturated humidity should also be removed from the environment in order to prevent diseases from spreading and developing.

Banana loves shade, the most suitable areas for growing under high trees.

When the temperature starts to drop below 20 ° C, there is a decline in growth and the banana is damaged at 3 ° C. - Under 4 C the body is damaged.

Measures should be taken against wind. The strong wind causes great damage to the banana due to its large leaves. False trunk can break, can cause the destruction of trees.

Banana green parts of the development period and fruit development period intensively requires nutrients. Only organic fertilizer application is not sufficient in banana cultivation. Mineral fertilizer application should also be done. Nitrogen, Phosphorus, Potassium, Calcium and Magnesium fertilization should be done.

The nitrogen requirement of bananas is also high. Nitrogen is required especially for the development of green parts. nitrogen is very important in the first three months, when the young plants appear and the growth starts. It uses a lot of nitrogen in the spring when the development starts and the plant starts attacking. It uses a large proportion of nitrogen in the first period.

There is a relationship between the use of nitrogen and the amount of dry matter. Phosphorus increases root growth and plant nutrient uptake capacity, strengthens cluster formation and is very important in terms of increasing the number of combs.

In order to remove the phosphorus from the soil, there should be enough water in the environment and the soil ph should be between 5.5 - 7.0. Application of phosphorus up to one month before birth increases the number of combs. In the absence of phosphorus, the edges of the leaves die and take the appearance of a sawtooth.

When phosphorus is sufficient, the number of combs and the number of fingers in each comb increases. However, excess phosphorus also has an adverse effect on the formation of fingers. Excess phosphorus reduces the number of combs and the number of fingers in the comb.

Phosphorus increases fruit yield, but decreases in excessive phosphorus fertilization.

In soils where excess phosphorus is applied, zinc is bound to iron and aluminum oxides to increase the growth of the plant, while the zinc concentration in the plant falls below the critical level, phosphorus toxicity can be seen in the plant. On the other hand, in cases where plants show zinc deficiency, the use of phosphorus fertilizers increases phosphorus toxicity (excess) in the plant as well as increases zinc deficiency.

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.

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

Potassium is very important in bananas. It is an essential nutrient for cluster formation and development, it accelerates plant growth and increases yield. In plants fed with a sufficient amount of potassium, the weight of the cluster increases, the fingers become larger and the fruit lasts longer in the market. Increases resistance to diseases and pests. Potassium ensures that the nutrients obtained as a result of photosynthesis in plant metabolism are transported to the areas where they will be beneficial. Adjusts the water balance of the plant. Potassium increases the product along with nitrogen and provides regular fruit set and ripening.

In the absence of potassium, the leaves turn yellow starting at the ends. This yellowing develops rapidly, killing most of the leaf starting from the tip.

Fruits of the plant that take low amounts of potassium become amorphous. Very few fingers are formed in the cluster.

Potassium determines the color and aroma of the product, weight and quality, size and hardness. At low potassium, the fruit becomes tasteless and uninspired.

Zinc deficiency is the most common plant nutrient deficiency in banana orchards. Zinc is one of the causes of plant nutrient deficiency due to excess phosphorus.

In the absence of zinc, the plant remains stunted. The leaves are small and narrow, with yellow-white strips between the second veins, which then turn into yellow-green strips. Long, brown dead spots appear on the yellow strips. The clusters of the plants with zinc deficiency are smaller and more curved than the normal curved shape, the most particular feature is the finger tips are light green. Excessive calcification or excess phosphorus in the soil may cause zinc deficiency.

Symptoms of manganese deficiency are similar to each other. In slight and moderate deficiency, young leaves reveal slight discoloration between the veins. If the deficiency is more severe, the discoloration increases and leaves the web appearance. In the later stage, to cover the surface of the leaf whitish yellow necroses. In iron-deficient leaves, the veins remain green, but the veins are yellow. Full rewind if deficiency progresses rigging and then drying.

Even the thinnest veins remain green and the color between these veins turns completely yellow. In broadleaf plants, the leaves show a green network view on a yellow background. In cases where deficiency is very severe, the veins also turn yellow.

In some plants, brown necrosis may occur in the leaves. If the deficiency is very severe, the leaf becomes white because there is no chlorophyll in the newly emerged leaves. Sometimes iron deficiency symptoms can be mistaken for magnesium deficiency symptoms.

It should be noted that magnesium deficiency is seen in the old leaves, whereas iron deficiency is seen in the young leaves, at the tops of the plants, at the shoot ends.

If the deficiency is mild, the last young leaves are initially yellowish green. As the deficiency progresses, the color between the veins turns completely yellow. The veins remain green with strict limits.

Soil usually contains enough calcium to meet plant needs. Particularly in arid and semi-arid areas, there is no bathing, so the saturation rate is high. Calcium is the primary element in the soil.

In arid soil soils formed on calcareous base material, calcium can be found in excess to create antagonistic effect on the uptake of some other nutrients, especially microelements.

As Turkey's lands also move these properties, so there is no need to be fertilizing the soil with calcium. However, it is possible to use calcium compounds for calcification in acidic places.

However, calcium deficiencies are seen in plants due to some factors. Decreases in calcium flow to the fruit and storage organs of plants cause problems due to calcium deficiency.

In banana calcium deficiency, young leaves first break up or down and leaf formation decreases.

The typical symptom of magnesium deficiency is yellowing between the veins in the aged leaves. The primary and secondary veins (first and second veins) retain their green color, and the third and thinner veins and the intervening areas turn yellow. The leaf has a mottled appearance. In extreme cases, chlorotic tissues die and form brown necrosis.

Especially in sandy soils, magnesium deficiency is common in plants towards maturity periods of plant development. The late magnesium deficiency may not lead to a major reduction in the amount of product. However, especially in plants grown for its leaves, market capability decreases. Soil compaction, submergence and drought exacerbate the lack of effect. In some cases magnesium deficiency can be seen in plants even if there is sufficient magnesium in the soil. High levels of hydrogen, potassium, ammonium, calcium ions in the soil solution may cause deficiency by reducing magnesium uptake. High amounts of aluminum ions in soils with pH 5 and lower also cause deficiency by reducing magnesium uptake.

Magnesium is the fourth and fifth leaves affected by deficiency. Leaf stalks break from the main stem, resulting in shorter life of the leaf.

Interaction between plant nutrients

There are serious competition or incentives among plant nutrients in terms of nutrient uptake of plants within the soil. Therefore, preparation and application of fertilization programs should be very careful. Implementing a regular and healthy fertilization program without soil analysis in greenhouse areas where the use of plant nutrients is the most can give negative results.


The ideal pH of the banana is 6. But it can grow at pH between 4.5 and 8.5. Since the soil of our country is generally calcareous, it generally exceeds PH 7 and PH 8 in some gardens.

Although bananas grow in a wide range of PHs, many of the plant nutrients from the base of the banana cannot receive the soil PH because it makes it difficult to take phosphorus, iron and phosphates from the base.

Plant nutrients accumulate in the soil due to insufficient intake, causing incompatibility between the elements.

The ratio of the elements in the fertilizers and the balance of these ratios, Soil Ph, excess fertilization and different fertilizers. service, (Agricultural engineering or technicians are planning to fertilize and disinfect according to an entire season.), we may face problems arising from the contrast between the elements.

Excessive use of even a single foodstuff may result in the removal of one or more other plant nutrients.

It can be mania.

In recent studies, it has been shown that the soil pH is 6.4. Attention should be paid to soil ph so that the inputs are too high or the given fertilizers do not accumulate in the soil.

As a result of the lack of plant nutrients, the plant will show many symptoms.

Potassium deficiency in plants with turgor pressure drops and water stress when plants become loose textured. Drought and frost resistance weakens.

Similarly, plants are much more sensitive to disease agents and salty soil conditions.

Abnormal developments are seen in plant tissues and cell organelles. The formation of xylem and phloem tissues in the plant regresses. Tissue ligninization is reduced. As a result, the body weakens in potassium deficiency.

Potassium is a nutrient that affects many quality elements in plants. Therefore, potassium deficiency in plants leads to various quality deteriorations depending on the characteristics of the plant.

Especially in vegetable, fruit and fiber plants, potassium deficiency affects the quality properties very negatively.

Since boron deficiency primarily damages the growth points of the plants, the growth of the plants is very slow. Leaves and branches easily break, take a crisp structure. If the deficiency is too severe, growth points die and growth stops completely. Flower is prevented from fruit formation, leaves curl, thicken and dark blue-green color.

Iron deficiency is more difficult to remove than other trace elements.

Because there are many factors that affect the usefulness of iron to the plant, as explained above.

It is not always possible to obtain positive results from every iron fertilization.
