1、Diospyros kaki ( Japanese Persimmon )

Fertilizers that are high in N, nitrogen, will promote green leafy growth. Excess nitrogen in the soil can cause excessive vegetative growth on plants at the expense of flower bud development. It is best to avoid fertilizing late in the growing season.

2、How to Fertilize Your Japanese persimmon for Optimal Growth?

For instance, if your Japanese persimmon shows signs of vigorous growth with little fruit, you may need to reduce nitrogen and increase potassium and phosphorus. Conversely, if the plant appears weak or shows nutrient deficiency symptoms, a balanced or nitrogen-rich fertilizer might be necessary.

3、Diospyros Kaki Plant Care & Growing Basics: Water, Light, Soil

Apply a complete fertilizer in early spring and midsummer. A complete fertilizer, such as 10-10-10, provides equal parts nitrogen, phosphorous and potassium. An oriental persimmon requires 2 ounces of fertilizer for each year of the tree's age, but split that amount between the spring and midsummer fertilizer applications.

Effects of supplemental fertigation levels on the growth and nutrient

Abstract: Supplemental nitrogen (N) and potassium (K) fertilization is of critical importance for maintaining tree vigor and producing high-quality fruits in persimmon (Diospyros kaki), especially under high fruit-load conditions.

Diospyros Kaki grows very slowly and doesn’t require added fertilizer. Replacing your plant’s potting soil once a year should provide them with more than enough nutrition.

A Comprehensive Review on Persimmon (Diospyros kaki): Botanical

Persimmon, belonging to the genus Diospyros, is a deciduous fruit tree renowned for its distinctive fruit and nutritional richness. This review provides a comprehensive examination of...

Diospyros Kaki L. F.

Nitrogen, potassium, and phosphorus are essential nutrients that Diospyros kaki L. f. needs to grow healthily. Fertilizers with a slow-release mechanism should be applied during the growing season to avoid nutrient leaching.

Analysis of Agrotechnical Care of Diospyros kaki Orchard Grown in the

The influence of organic and inorganic fertilizers on the development of Diospyros kaki varieties was studied. The greatest development of 3-year-old trees was observed with the application of N50P20K35+20 tons/ha of inorganic fertilizer (manure).

Diospyros kaki, Agroforestry Database

In Japan, 1 000 plants/ha may be planted at the outset, and thinned down to 200 trees/ha in 10-15 years. Good results have been obtained with a fertilizer mixture of 4-6% N, 8-10% P and 3-6% K at the rate of 0.45 kg/tree per year of age. Over-fertilization or excessive amounts of nitrogen fertilizer causes shedding of fruits.

Excess nitrogen can cause fruit drop. If mature leaves are not deep green and shoot growth is less than a foot per year, apply a balanced fertilizer such as a 10-10-10 at a rate of l pound per inch of trunk diameter at ground level. Spread the fertilizer evenly under the canopy in late winter or early spring.

Diospyros kaki, commonly known as the persimmon, is a deciduous tree species native to southern China and Southeast Asia. Belonging to the genus Diospyros in the family Ebenaceae, it is widely cultivated for its edible fruits.

In agricultural practices, the demand for nitrogen fertilizer varies among plant species, growth stages, and environmental conditions. As a fruit-bearing tree, Diospyros kaki indeed requires nitrogen fertilizer to fulfill its nutritional needs. Below is a detailed explanation of why nitrogen is essential for this species and how it should be applied:

1. Importance of Nitrogen to Plants

Nitrogen is a critical macronutrient for plant growth, playing indispensable roles in processes such as:

• Chlorophyll synthesis: Enables photosynthesis.
• Protein synthesis: Supports cellular structure and enzyme function.
• Energy metabolism: Facilitates ATP production.

Deficiency in nitrogen leads to stunted growth, yellowing leaves, reduced flowering, and poor-quality fruits with diminished flavor. Thus, proper nitrogen application is vital for enhancing growth and yield in persimmon trees.

2. Nitrogen Requirements in Diospyros kaki

As a fruit tree, Diospyros kaki relies on nitrogen for key developmental stages:

a) Leaf Growth: Nitrogen promotes leaf expansion and differentiation, providing adequate foliage for photosynthesis. Early growth stages are particularly sensitive to nitrogen availability due to underdeveloped root systems.

b) Flower Bud Differentiation and Blooming: Adequate nitrogen ensures normal flower bud formation and blooming, directly impacting fruit set rates.

c) Fruit Development: Nitrogen influences fruit size, color, and sugar content. It stimulates cell elongation, improves texture, and enhances sweetness.

d) Root System Development: Nitrogen fosters robust root growth, improving nutrient uptake efficiency and overall plant stability.

3. Types and Application Methods of Nitrogen Fertilizer

Farmers can choose from various nitrogen sources, including:

• Synthetic fertilizers: Urea, ammonium nitrate, ammonium sulfate.
• Organic options: Farmyard manure, green manure.

Application Strategies:

• Base Fertilization: Apply evenly before planting to enrich soil organic matter and structure.
• Topdressing: Adjust applications during growth phases based on soil tests, using furrow or hole methods to prevent root burn.
• Foliar Spraying: For drought-sensitive varieties, apply water-soluble nitrogen solutions directly to leaves for quick absorption.

4. Precautions

• Optimal Dosage: Excessive nitrogen may cause delayed maturation, reduced fruit quality, or soil acidification/salinization. Adjust based on soil fertility and plant health.
• Balanced Nutrients: Combine nitrogen with phosphorus (P) and potassium (K) to ensure comprehensive nutrition.
• Prevent Loss: Minimize runoff by timing applications to avoid rain and using soil-stabilizing techniques.

Diospyros kaki requires nitrogen fertilizer to support its nutritional demands, particularly during leaf, flower, fruit, and root development. Rational nitrogen use boosts growth, yield, and fruit quality. careful management—including balanced application, dose control, and eco-friendly practices—is crucial to achieving high-quality, sustainable persimmon production.
