1、Foliar fertilization with a soluble silicon source can alter pigment

Foliar fertilization with silicon appears feasible for fruit production in plants considered intermediate accumulators of this element, such as cucumbers.

2、Foliar application of silicon and selenium improves the growth, yield

The results showed that Si and Se application individually or in combination enhanced the photosynthesis, growth and yield of cucumber. Application of Si and Se respectively increased their concentrations, and accumulations of soluble sugars and amino acids in the fruit.

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.

4、Foliar Fertilization: Novel Approaches and Field Practices

In this Special Issue, special attention is paid to various aspects of foliar fertilization, especially with regard to plant growth and development, physiological traits, incidence of diseases and pest feeding, and quantity and quality of production.

Foliar Feeding of Cucumbers: How to Correctly Apply It and Boost Yield

Apply fertilizers in the evening or when the weather is cloudy. When cucumbers begin to bear fruit, organic fertilizers are best. Always wear protective equipment when working with fertilizers. Thoroughly wash the container that held the fertilizer after use.

Optimization of Water and Nitrogen Application Rates for Synergistic

By employing a regression formula and spatial analysis methods, this study optimized the water and nitrogen application rates with the goals of maximizing the cucumber yield, water–nitrogen efficiency, and quality.

Impact of Foliar, Mineral Fertilization and some Plant Activators on

Thus, it can be recommended that use 75% NPK from recommended dose plus foliar application NPK and foliar spray with moringa leaf extract applications to decrease mineral fertilization...

Can Foliar Fertilization Be Used at 30°C in Northern Regions?

Foliar fertilization of crops can complement soil fertilization. If foliar fertilization is mixed with postemergence herbicides, insecticides, or fungicides, the probability of yield response could be increased and cost of application can be reduced.

Foliar feeding of cucumbers: what fertilizers and how to apply

During the foliar feeding of cucumbers in the greenhouse, various solutions are used that contain a large amount of useful substances. Before you start fertilizing, you need to familiarize yourself with which solutions are used for this.

Foliar nutrition: Potential and challenges under multifaceted

The potential of foliar fertilization in improving crop yield and quality under environmental stresses has been evaluated based on a meta-analysis. Foliar-applied fertilizers showed higher crop plants yield and quality traits by 15–19% and 9–29%, respectively, under different environmental stresses.

Foliar fertilization is an effective method to supplement nutrients and enhance cucumber yields in northern China, especially on cloudy days. Below are detailed steps and precautions for implementation:

I. Preparation Phase

1. Selecting Foliar Fertilizer

   • Choose appropriate fertilizers (e.g., potassium dihydrogen phosphate, urea, boron fertilizer) based on cucumber growth requirements.
   • Check packaging instructions to ensure compatibility with cucumbers and follow recommended dosages.

2. Tool and Material Preparation

   • Use a clean sprayer (manual or electric) free of blockages.
   • Prepare clean water for diluting the fertilizer.
   • Maintain a record book or digital log to track fertilization timing, dates, and dosages.

3. Soil Preparation

   • Ensure soil moisture is adequate but avoid waterlogging.
   • For first-time use, conduct a small-scale trial in a non-critical area to observe cucumber responses.

II. Applying Foliar Fertilizer

1. Dilution

   • Mix the fertilizer with water according to the manufacturer’s instructions. For example, dilute potassium dihydrogen phosphate at a ratio of 1:500.
   • Stir thoroughly until fully dissolved.

2. Spraying

   • Adjust the sprayer to a moderate flow rate to prevent nutrient loss.
   • Spray the solution evenly onto cucumber leaves, focusing on the undersides where absorption is most efficient.
   • Adjust coverage based on plant size: larger plants require broader spraying, while smaller ones need less.

III. Precautions

1. Avoid Over-Fertilization

   • Adhere strictly to recommended dosages to prevent root burn. Discontinue use if adverse reactions occur.

2. Protect from Direct Sunlight

   • Shield plants from sunlight after spraying to prevent nutrient breakdown. Move plants to shade temporarily until the solution dries.

3. Timely Watering

   • Irrigate after spraying to aid nutrient absorption. Avoid direct water jets on leaves to maintain efficacy.

4. Monitor Plant Response

   • Observe growth metrics (e.g., leaf color, fruit development, and growth rate). Address abnormalities promptly by identifying causes.

Foliar fertilization on cloudy days can effectively boost cucumber nutrition and yields in northern regions. adjust application methods based on specific conditions and closely monitor plant responses for optimal results. Flexibility and observation are key to maximizing benefits.
