5、Effects of boron fertilizer on the yield and quality of rapeseed

This article introduces the types, characteristics, and application methods of boron fertilizer, explores the impact of boron fertilizer on rapeseed yield and quality, and elucidates the mechanism of boron in the formation of rapeseed quality.

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.

Effects of boron fertilizer rates on the yields and boron use

Considering the agronomic characters, yield and utilization efficiency of boron fertilizer, it is recommended that the amount of boron fertilizer used in this rapeseed planting area should be about 15.00 kg/hm~2.

The effect of boron fertilizer on rapeseed

At present, the most commonly used boron fertilizer in domestic rapeseed production is borax (sodium salt of boron), which is low in price and convenient to use. The content of boron is 11%, and the active ingredient is less than boric acid, but the use effect is the same.

All the B treatments (<italic>P</italic><0.05) increased the oil, oleic, and linolenic acid contents in rapeseed, with a maximum increase of 10.3%, 15.8%, and 22.7%, respectively. Similarly, a maximum reduction of 19.4%, 36.1% and 14.1% in linoleic, palmitic, and stearic acid contents were recorded.

Excessive amount of boron fertilizer is not conducive to the absorption of nitrogen, phosphorus and potassium nutrients in rapeseed. Based on the above studies, it is recommended that the applicable amount of boron fertilizer in rape production in this region is 7.5 kg/hm2.

In agricultural production, boron fertilizer is an essential nutrient that significantly impacts the growth and yield of rapeseed. Proper application of boron fertilizer can effectively enhance disease resistance, promote flower bud differentiation, increase effective tillering, and ultimately improve both the yield and quality of rapeseed. So, how much boron fertilizer per mu is appropriate for rapeseed? The following provides a detailed analysis.

First, it is crucial to understand the role of boron fertilizer. As a vital microelement for plant growth, boron regulates cell division and elongation, facilitates pollen germination, and strengthens stress resistance in plants. For rapeseed, boron fertilizer specifically promotes flower bud differentiation, increases effective tillering, and boosts yield and quality.

Second, the growth stage of rapeseed must be considered. Boron requirements vary across different stages: higher during the seedling and flowering stages, and lower during the pod-forming stage. Thus, boron application rates should be adjusted according to the specific growth phase.

Third, soil conditions play a critical role. Both boron content and pH levels in the soil affect fertilizer efficacy. If soil boron is deficient or pH is suboptimal (too high or low), boron absorption decreases. Conducting pre-application soil tests to assess boron levels and pH is essential for determining optimal boron rates.

Fourth, climatic factors influence boron availability. Drought and high temperatures accelerate boron loss from soil, while humidity and low temperatures reduce its effectiveness. Adjust boron application based on local weather patterns—e.g., increasing rates in dry regions and reducing them in humid areas.

Key Recommendations:

1. Growth Stage-Specific Application:

   • Seedling and Flowering Stages: Apply 1–2 kg/mu of boron fertilizer.
   • Pod-Forming Stage: Reduce to 0.5–1 kg/mu.

2. Soil-Based Adjustments:

   • If soil boron < 1 ppm, apply 3–4 kg/mu.
   • If soil boron > 5 ppm, reduce application to avoid excess.

3. Climate-Driven Adjustments:

   • In arid regions, increase boron slightly.
   • In humid regions, decrease boron slightly.

4. Avoid Overapplication: Excessive boron accumulates in soil, disrupting nutrient balance.

Determining the ideal boron rate for rapeseed requires integrating growth stage, soil conditions, climate, and soil test results. Scientifically balanced boron application optimizes yield and quality, delivering better economic returns for farmers.
