1、FOLIAR FERTILIZATION TIMING IN 'FARMACISTA HONORATI' PERSIMMON

Four different foliar fertilizer regimes were tested on nine-year-old trees of Farmacista Honorati persimmon (Diospyros kaki L.) grown in northern Sicily.

2、Effect of different foliar potassium fertilization forms on vegetative

Table 3. present the effect of different potassium fertilization forms (KCl, K 2 SO 4, and K-NPs) were applied four times on different fruit developmental stages (Full bloom, fruit set, greenish-yellow color stage, and at harvest time) during two growth seasons (2019 and 2020) of ‘Costata’ persimmon on chlorophyll fluorescence parameters.

3、Effects of Foliar Fertilization: a Review of Current Status and Future

Foliar fertilizer application after soil fertilization is an effective method to increase the contents of trace elements in crops and crop yield, and to improve the soil environment. However, the application of inorganic foliar fertilizer results in difficulties in nutrient absorption and migration in plants.

Properly Timing Foliar

Foliar fertilization efficiently meets the nutrient demand of tree fruit crops during periods when soil conditions (low or high temperatures, low or excess soil moisture, pH, salinity)...

When to Fertilize Persimmon Trees?

A second, lighter application can be applied in late spring or early summer, after fruit set, to support fruit development and improve fruit quality. Avoid fertilizing late in the summer or fall, as this can stimulate new growth that is susceptible to frost damage.

Effects of plant regulators and leaf fertilization on fruit quality

Therefore, this study aimed to determine the quality changes of persimmon fruits treated with plant regulators and leaf fertilization during on-tree storage period and cold storage period (4 ℃), and also to detect the effects on next-year fruit quality and yield, in order to provide a theoretical basis for persimmon on-tree storage.【Methods ...

The in-tense bloom resulted in a large num-ber of fruit being set, with or without foliar-applied urea or GA3, which likely saturated the carrying capacity of the trees, making it difficult to enhance fruit set further.

When Should You Fertilize Your Persimmon Trees for Optimal Growth?

Discover the best timing for fertilizing persimmon trees to ensure optimal growth and fruit production. Our guide provides essential tips on when to apply fertilizers, helping you maximize your tree's health and yield.

Impact of foliar fertilization on apple and pear trees in reconciling

Moreover, it has become evident that foliar nutrients can regulate flowering, fruit yield and fruit quality. An extensive experiment was undertaken to study the potential effect of foliar fertilization on apple and pear trees to ameliorate productivity and alleviate environmental stresses.

Effect of foliar applied phosphatic fertilizer on absorption pathways

These results allow us to infer that foliar application of FMCP fertilizer was not only augmenting the fruit yield of sweet persimmon but also improved the quality of produce. 1. Introduction. Sweet persimmon (Diospyros discolor) is a multitranked or single stemmed deciduous tree.

The fruit set period of persimmon trees is a critical stage before fruit maturation, during which nutrient supply directly impacts fruit quality and yield. Foliar fertilization is an efficient method to quickly replenish essential nutrients, enhancing plant growth and fruit quality. Applying foliar fertilizers during this period provides necessary nutrition, promotes flower bud differentiation, and increases fruit quantity and quality.

I. Understanding the Characteristics of the Fruit Set Period

1. Flower Bud Formation and Development: During the fruit set period, flower buds begin to form and develop, determining fruit quantity. Hormonal changes within the plant affect bud formation and development, subsequently influencing fruit quality and yield.
2. Nutrient Demand Changes: As flower buds develop, the plant’s demand for nutrients shifts. Increased nitrogen (N), phosphorus (P), potassium (K), and micronutrients are required to support bud differentiation and growth.
3. Environmental Impact: Temperature, light, and water significantly affect this stage. Optimal conditions promote bud development, leading to higher yields and better fruit quality.

II. Selecting Suitable Foliar Fertilizers

1. Compound Fertilizers: Choose products containing multiple nutrients (e.g., N, P, K) and microelements to meet the plant’s diverse needs during the fruit set period.
2. Micronutrient Fertilizers: Calcium (Ca), magnesium (Mg), zinc (Zn), and other trace elements are critical for bud formation and fruit development. Balanced supplementation improves yield and quality.
3. Organic Fertilizers: Natural plant-based formulations reduce chemical exposure risks. Organic options provide safe, comprehensive nutrition while minimizing environmental impact.

III. Determining Concentration and Application Methods

1. Concentration Control: Dilute fertilizers to 1/5–1/4 of the original strength. Adjust based on plant health and soil moisture to avoid over-concentration.
2. Timing: Apply in the morning or evening to prevent sunlight degradation of nutrients. Avoid mid-day heat to reduce evaporation.
3. Application Technique: Spray uniformly on leaves, avoiding direct contact with fruits or flowers. Use a fine mist sprayer or soft brush to ensure full leaf coverage.

IV. Key Precautions

1. Avoid Overapplication: Excessive use can lead to toxicity. Follow recommended dosages strictly.
2. Combine with Other Fertilization Methods: Integrate foliar sprays with base fertilization (e.g., organic matter) and topdressing to optimize nutrient uptake.
3. Monitor Plant Response: Watch for signs of stress (e.g., yellowing, wilting). Adjust concentrations or consult experts if adverse reactions occur.

Foliar fertilization during the persimmon tree’s fruit set period is an effective strategy to enhance nutrient availability, promote flower bud development, and improve yield and quality. Success depends on selecting appropriate fertilizers, using correct concentrations, and adhering to best practices. Scientific application of foliar fertilizers lays a robust foundation for healthy tree growth and high productivity.
