1、The Effect of Autumn Foliar Fertilization on the Yield and Quality of

When applied in BBCH stages 14 and 16, foliar fertilizers stimulated the development of leaf rosettes, increased the accumulation of minerals in aerial rosette parts (N, K, and Mg) and roots (K, Cu, Mn, and Fe), and contributed to the overwintering success of winter oilseed rape plants (by 8–11%).

2、Growing Oilseed Rape

Foliar fertilizers are a common practice in fertilizing oilseed rape and may boost plant development and strengthen plants against abiotic factors (e.g., drought, heat, cold soils), and biotic factors (e.g., pests and diseases).

3、What Fertilizer Is Used For Rape Seed

The application of two-component fertilizers, such as magnesium and sulfur, can satisfy the autumn nutrient needs of rapeseed. A liquid NP fertilizer supplemented with boron is recommended as a starter solution for both autumn and spring establishment. Timing and appropriate forms of nutrient application, such as foliar sprays of phosphorus and potassium, are critical, with the first nitrogen ...

The response of different kinds of rapeseed cultivars to foliar

The aim of the study was to determine the effect of foliar application of sulphur, boron, amino acids on the use and feed value of seeds of three winter rape morphotypes.

Effects of a controlled

In conclusion, CRF significantly promoted the growth of rapeseed with using total N as the base fertilizer, by providing sufficient N in the later growth stages, and last by reducing the residual N in the soil and increasing the N accumulation and N usage efficiency.

The impact of complex foliar fertilization on rapeseed cultivation

Foliar fertilization provides cultivated plants with the necessary nutrients during the growing season.Following the study, it was observed that foliar fertilization led to a significant...

Recommendations for foliar feeding of rapeseed

Rapeseed absorbs about 15-25% of nutrients from soil reserves, and the rest should be applied in the form of organic and mineral fertilizers. Full use of mineral nutrients by plants is possible only if all elements are provided.

The response of different kinds of rapeseed cultivars to foliar

The aim of the study was to determine the effect of foliar application of sulphur, boron, amino acids on the use and feed value of seeds of three winter rape morphotypes.

Foliar Application of Growth Regulators Mitigates Harmful Effects of

Overall, foliar application of ascorbic acid, salicylic acid, and methanol improved the seed yield and oil quality of rapeseed under optimal water supply and drought-stress regimes.

Effect of layered fertilizer strategies on rapeseed

Our study demonstrate that layered fertilization can improved rape growth and soil macropore porosity, but its effect depends on good tillage macropore characteristics and distribution...

Rapeseed (Brassia napus), also known as vegetable rape, greens, or cauliflower, is an annual herbaceous plant belonging to the Brassica genus in the cruciferous family. In agricultural production, rapeseed is a critical oil crop and vegetable. To enhance its yield and quality, farmers often explore various methods to promote its growth, among which foliar fertilization is a simple and effective approach.

Foliar Fertilization refers to applying fertilizers directly onto the surface of plant leaves, enabling nutrient absorption through foliage to stimulate plant growth. For rapeseed, early seed maturation is key to improving yield and quality. selecting appropriate foliar fertilizers to accelerate seed maturation is particularly crucial.

Currently, numerous foliar fertilizer products are available on the market, such as potassium dihydrogen phosphate, urea, ammonium sulfate, and borax. While these fertilizers generally promote plant growth, their effectiveness varies depending on the crop and growth stage. When choosing foliar fertilizers, consider the following:

1. Identify the Target Crop: Different crops have distinct nutritional needs. Clearly define the target crop to select suitable fertilizers.

2. Understand Growth Stages: The timing of foliar fertilization depends on the crop’s growth cycle. For rapeseed, early and mid-growth stages are optimal for foliar application.

3. Analyze Fertilizer Components:

   • Potassium dihydrogen phosphate is rich in phosphorus, promoting root development and disease resistance.
   • Urea, a nitrogen-based fertilizer, boosts stem and leaf growth and photosynthetic efficiency.
   • Ammonium sulfate accelerates flowering and fruiting.
   • Borax, a microelement fertilizer, enhances pollen formation and seed setting.

4. Application Methods:

   • Spraying suits large-scale fields.
   • Smearing works for small areas.
   • Soaking benefits plants with发达的 root systems.
   • Control dosage and frequency to avoid overuse, which may scorch plants.

5. Monitor Plant Response: After application, observe for signs like yellowing or wilting, indicating improper use or excess, requiring timely adjustments.

6. Integrate with Other Practices: Foliar fertilization should complement other agronomic techniques, such as optimal plant density, scientific irrigation, and pest control, to maximize yield and quality.

selecting the right foliar fertilizer to promote early rapeseed maturation requires综合考虑 target crops, growth stages, fertilizer components, application methods, plant responses, and integrated agricultural practices. By addressing these factors, farmers can effectively improve rapeseed yield and quality.
