1、Foliar fertilization of rice

Spray should be applied when the plants are fully turgid, and should be avoided during hot and dry weather. Best results are obtained when spraying in the late evening or early morning.

2、How foliar feeding works on rice

Rice crop nutrition and fertilisation is the centrepiece in this scenario with foliar feeding driving the innovation needed. Rice requires the full gambit of essential plant nutrients in measured amounts with application timing in relation to stage of rice plant development as the key to success.

3、The 10 Best Rice Fertilizers to Increase Paddy Yield

To address these challenges and enhance rice yields, the use of specific fertilizers and best practices is essential. Here is a detailed guide on the nine best fertilizers to boost rice production and how to apply them effectively.

4、How to Use Foliar Spray Fertilizer Effectively?

In this guide, we’ll walk you through everything—from fundamentals to field practice—to help you use foliar spray fertilizers efficiently and effectively.

Methods of Fertilizer Application in Rice Plants

Foliar application involves applying liquid fertilizer directly to the leaves of the rice plants. This method is excellent for addressing micronutrient deficiencies quickly.

Application Progress and Prospect of Rice Foliar Fertilizer

Rice foliar fertiliser has been shown to boost rice output, improve rice quality, and minimise heavy metal pollution, particularly cadmium pollution, in the field.

Effects of foliar fertilizer on rice growth and yield

Among them, the microbial foliar fertilizer Miaodundun, the regulatory foliar fertilizer Abscisic acid + Indolebutyric acid, and the compound foliar fertilizer Zhenfengrui combination demonstrated better yield increasing and income enhancing effects.

Film mulching combined with chemical fertilizer increased rice yield by

The study aimed to explore the effects of plastic film mulching and different types of fertilizers on the growth of rice and the transportation of photosynthetic substances.

How To Apply Fertilizer On Rice Farm

Accurate fertilizer application is vital for maximizing yields, and the Haifa Group’s Rice Crop Guide outlines best practices, including foliar feeding and spray applications.

Application of different foliar iron fertilizers for enhancing the

Overall, different foliar-applied Fe fertilizers modified the antioxidant ability of rice to different extents, and a moderate dose of chelated ferrous Fe was the most effective approach for increasing Cd tolerance.

Foliar fertilizer, also known as leaf spray fertilizer or foliar topdressing, is a type of nutrient solution applied to the surface of plant leaves via spraying. It can be rapidly absorbed by plants, directly supporting physiological activities, accelerating growth, enhancing stress resistance, and improving crop quality. For rice, proper use of foliar fertilizer can effectively promote development and increase yields. Below are guidelines and efficacy analysis for using foliar fertilizer on rice:

I. Selection and Dilution of Foliar Fertilizer

1. Choose the Appropriate Fertilizer: Select fertilizers based on nutritional content, solubility, stability, and crop safety. Common options include urea, potassium dihydrogen phosphate, magnesium sulfate, and microelement fertilizers.
2. Proper Dilution: Dilute the fertilizer according to package instructions, typically at ratios of 1000:1 to 5000:1, depending on the product and crop needs.
3. Check Color and Odor: High-quality foliar fertilizer should be colorless or pale yellow with no irritating smell. Discoloration or strong odors may indicate poor quality or excessive additives.

II. Optimal Timing for Application

1. Critical Growth Stages: Apply during key rice growth stages (tillering, booting, and heading) to boost growth and yield. For example, nitrogen-rich foliar fertilizer during the jointing stage accelerates plant development.
2. Disease/Pest Control: Use foliar fertilizers containing copper, zinc, or other microelements to combat diseases, reducing reliance on pesticides.
3. Drought or Water Scarcity: Apply nutrient-rich foliar fertilizers to alleviate stress and support crops during dry periods.

III. Application Methods

1. Even Spraying: Use a sprayer to distribute the solution uniformly across leaves, avoiding localized overdose (which can burn foliage).
2. Avoid Direct Sunlight: Apply in the evening or on cloudy days to prevent leaf scorching from high temperatures.
3. Multiple Applications: Depending on crop needs and soil conditions, repeat applications may be required for optimal results.

IV. Precautions and Recommendations

1. Avoid Overapplication: Excessive use can toxicify plants or damage roots. Follow recommended dosages.
2. Weather Considerations: Avoid applying during high heat, strong winds, or rain to ensure effectiveness.
3. Combine with Soil Fertilization: Integrate foliar fertilizers with organic or soil-applied fertilizers to enhance nutrient uptake and improve soil health.

Foliar fertilizer is a vital tool for rice production. When used scientifically—considering crop stages, weather, and application techniques—it significantly boosts growth and yield. Farmers should tailor practices to local conditions and crop requirements for maximum benefits.
