Effect of balanced application of boron and phosphorus fertilizers on

Abstract Rapeseed (Brassica napus L.) is extremely sensitive to both boron (B) and phosphorus (P) deficiencies. Application of chemical fertilizers is generally considered to be an effective agronomic practice to improve crop productivity, and it also affects soil bacterial community.

Effects of Different Boron Fertilizer Dosage on Yield and Nutrient

The yield and benefit of rapeseed decreased with excessive application of boron fertilizer. The yield was the highest when applying 7.5 kg/hm2 boron fertilizer, with an average increase of 19.33% and a production to investment ratio of 47.47.

Rape science boron application technology

The special fertilizer for rapeseed balanced fertilization is a highly targeted special formula fertilizer developed according to the physiological fertilizer characteristics of rapeseed, target yield and the content of nitrogen, phosphorus, potassium and trace elements in different soils.

How to use boron fertilizer in rapeseed field

1. Ke Shi: The main supply of borax and ten element boron fertilizer in Ningbo Agricultural Market is the main method of applying borax. Generally, borax is used. The dosage is 0.5-1.0 kg per mu, which can be mixed with fine mud. Or fertilizer in the ditch or acupoint application.

Boron Nutrition and Boron Application in Crops

In this paper, we will review the respective progress and report about the Chinese studies on the function of B, diagnosis of B status of plants and techniques of B fertilizer application.

Effects of boron application rate on double

The yield, seed boron concentration, main quality indexes, and fatty acid fractions of rapeseed were determined, and the correlations among the factors were analyzed.

Optimizing boron application methods and dosages to enhance jute

Ten boron fertilization treatments were generated, each with a different dose of boron (2 kg per hectare (kg/ha), 3 kg/ha, and 4 kg/ha), three application methods (basal, foliar, and basal + foliar), and a control treatment with no boron application (Table 2).

Rapeseed (Brassica napus L.) is an important oil crop with a relatively high demand for boron. Boron plays a critical role in its growth, development, and yield. Boron fertilizers promote root development, enhance photosynthetic efficiency, increase the number of siliques, and boost seed production. Proper application of boron fertilizers not only improves rapeseed yield but also enhances its quality. Below is a detailed guide on the application methods and dosage of boron fertilizers for rapeseed:

I. Classification and Selection of Boron Fertilizers

1. Classification of Boron Fertilizers: Boron fertilizers are divided into organic boron and inorganic boron based on their chemical properties. Organic boron fertilizers primarily exist in the form of borates or borax, while inorganic boron fertilizers include boric acid, sodium borate, ammonium borate, etc.

2. Selection Principles: When choosing boron fertilizers, consider the growth stage of rapeseed, soil conditions, and climatic factors. For example, use slowly released boron fertilizers with higher boron content during early spring growth, and opt for fast-release boron fertilizers before autumn harvest to ensure nutrient supply.

3. Brand and Quality: Select products from reputable brands to ensure purity and effectiveness. Check labels on packaging for details on content, ingredients, and application methods.

II. Application Timing and Methods

1. Application Timing: Rapeseed absorbs boron primarily during flowering. Apply boron fertilizers as a base fertilizer 7-10 days after sowing and as a topdressing fertilizer during the flowering stage.

2. Application Methods: Boron can be applied through foliar spraying, soil application, or root-zone fertilization:

   • Foliar Spraying: Dilute boron fertilizer and spray directly onto leaves for rapid absorption.
   • Soil Application: Spread boron fertilizer on soil surfaces or furrows, then incorporate it into the soil.
   • Root-Zone Fertilization: Apply near roots to promote root development and nutrient uptake.

3. Precautions:

   • Avoid excessive application, which may cause growth abnormalities or soil contamination.
   • Adjust dosage based on rapeseed varieties and consult professional advice if needed.

III. Dosage and Proportioning

1. Dosage Calculation: Boron dosage depends on growth stages, soil fertility, and climate. Generally, apply 5-10 kg/mu of organic boron or 1-2 kg/mu of inorganic boron. Adjust according to field conditions.

2. Proportioning Principles: Follow the "small amounts, multiple applications" principle to minimize soil boron concentration fluctuations and prevent plant damage.

3. Adjustments:

   • Increase boron in poor or dry soils.
   • Reduce boron in fertile or irrigated soils.

IV. Precautions and Recommendations

1. Avoid Continuous Cropping: Rotate crops to prevent boron depletion in soil, ensuring sustainable rapeseed growth.

2. Safety Measures:

   • Boron is toxic; avoid mixing with acids to prevent harmful reactions.
   • Ensure ventilation during application to avoid inhaling fumes.

3. Monitoring and Adjustment:

   • Regularly test soil boron levels after application.
   • Supplement boron promptly if deficiencies are detected.

Proper boron fertilization is crucial for improving rapeseed yield and quality. By mastering application methods and dosages, farmers can effectively meet rapeseed’s boron needs and promote healthy growth.
