“Secrets” to Fertilizing Durian Trees with Viet Nga Fertilizer

The durian tree is a popular crop in tropical regions, and its delicious flavor and various preparation methods have led to high demand for this fruit.

For durian trees to grow well and produce high-quality fruit, proper care and maintenance are extremely important.

In this article, let’s explore with Viet Nga Fertilizer the process and techniques of fertilizing durian trees to achieve high efficiency and good yields!

1. Determine the nutritional requirements of the durian tree.

1.1. Nutritional requirements

Nutrients are crucial for stable plant growth and development, increasing yield and producing high-quality fruit.

Durian trees require sufficient amounts of macro, micro, and trace elements; a deficiency in any of these components during cultivation will lead to poor tree growth.

Depending on the stage of the tree’s growth, the nutritional requirements will vary. The fruiting and growth stages of the durian tree require both macronutrients and micronutrients, including:

• N, P and are most essential during the fruit development stage.
• Potassium (K) is an essential nutrient during the later stages of fruit development until harvest.

1.2. The roles of the elements N, P, and K in durian trees.

1.2.1. Nitrogen (N):

This is a crucial component for the development of all parts of the plant and is especially essential for vegetative growth.

• Nitrogen deficiency: This often occurs in nutrient-poor soils and when insufficient nitrogen is applied, resulting in plants lacking density, excessive leaf drop, and reduced yield.
• Excess nitrogen: Promotes vigorous vegetative growth, making the plant more susceptible to pests and diseases, and leads to abnormal fruit development such as loss of spines or fruit cracking.

1.2.2. Phosphorus (P):

Durian trees require relatively little phosphorus, so phosphorus fertilizer should be applied in small amounts. It is necessary to apply phosphorus fertilizer as a base dressing in the planting hole before planting to help the tree grow in the initial stage.

• Phosphorus deficiency: Leaves turn dull yellow, fall off, and branches die.

1.2.3. Potassium (K):

Potassium is crucial for fruiting plants, making them strong, less prone to lodging, and increasing their resistance to waterlogging and drought. Applying potassium fertilizer is essential for maintaining high yields and good fruit quality.

• Potassium deficiency: Leaf margins turn yellow-orange, then gray-brown and dry out, and many leaves fall off.

2. The effectiveness of fertilizers on durian trees

• Nutritional support: Contains many essential nutrients such as Nitrogen (N), Phosphorus (P), Potassium (K), and many other minerals that plants need for growth.
• Improving soil structure: This helps improve soil structure by creating a better environment for root development, making it easier for plants to absorb water and nutrients.
• Improving interaction with soil microorganisms: Providing food for bacteria and other microorganisms in the soil, helping to break down organic matter and improving the plant’s interaction with the soil.
• Increased water retention: This helps increase the tree’s ability to retain water, enabling the durian tree to survive well during dry periods.

3. When to fertilize plants

The amount and method of fertilizing plants will vary depending on the time of year.

Proper fertilization techniques help provide plants with sufficient nutrients and improve soil structure, leading to healthier growth, fewer pests and diseases, and higher yields.

3.1. Pre-planting stage

The best time to apply base fertilizer to durian trees is usually 10-15 days before planting. This helps provide timely nutrition as the tree begins to develop roots.

Norwegian Gronn 75% OM organic fertilizer is a product specifically designed for base fertilization and top dressing, stimulating root development, increasing the efficiency of mineral fertilizers, supplementing nutrients, and enhancing metabolic processes to promote healthy and rapid plant growth.

3.2. Stages of plant development

3.2.1. Before inducing flowering

Fertilize when the leaves have just turned dark green, neither too old nor too young, to support flower bud formation. Flower induction treatment should only begin 10-15 days after fertilization.

It is recommended to use NPK fertilizer with high phosphorus and high potassium content, or if using single fertilizers, use DAP + potassium in a 1:1 ratio, applying 1-2 kg per plant depending on the size of the plant.

3.2.2. Cotton growing stage

The flower development stage, from the time the flower bud emerges to a height of 0.5-1cm until flowering and full bloom (pollination), takes approximately one month.

Applying NPK 30-10-10 + DAP + Calcium Nitrate Boron fertilizer helps provide calcium and boron, increasing pollination, reducing flower and young fruit drop.

The amount of fertilizer depends on the plant’s vitality; increase or decrease it to just enough to nourish the flowers. Over-fertilizing will cause the plant to over-propel, leading to flower drop.

3.2.3. Fruit development stage

At this stage, the fruit grows very quickly, so it needs a high protein supply.

Use the NPK 30-10-10 + Calcium Nitrate Boron product set to reduce fruit rot and fruit drop, while also providing nutrients to the soil and enhancing root vitality.

One thing to note is that farmers should avoid over-fertilizing as it will cause new shoots to sprout and compete for nutrients with other young fruits.

3.3. Recovery phase

During the fruit-bearing stage, the tree will not produce new leaves but will instead shed them. In addition, the root system, which is responsible for absorbing nutrients, is also significantly damaged, so restoring the tree during this stage is very important.

– Using Gronn 75% OM Norwegian organic fertilizer helps plants recover their root system, providing nutrients gently without damaging the roots, and loosening the soil to create an ideal environment for new roots to grow and develop.

– Using Viet Nga NPK 30-10-10 + DAP 18-46-0 fertilizer at a mixing ratio of 1:3 helps plants develop strong shoots, as well as promote root growth and thicker foliage.

4. Note the 5 correct principles for fertilizing durian trees.

To achieve high productivity and quality, during the fertilization process for durian trees, we need to pay attention to the following 5 correct principles:

• Apply the right type of fertilizer: Plants need a sufficient supply of macronutrients (N, P, K) and micronutrients (S) for their growth.
• Fertilize according to the plant’s needs: The nutritional requirements of different fertilizers vary at each stage of growth, so providing the right nutrients will help the plant grow well.
• Proper fertilization according to soil conditions helps to enhance the balanced supply of nutrients and promotes the more effective development of soil microorganisms.
• Apply fertilizer at the right time: Fertilizer should be applied in the early morning or late afternoon.
• Proper fertilization methods: There are many fertilization methods such as furrow fertilization, hole fertilization, and foliar spray fertilization.
