Applying Boron Fertilizer at Different Growth Stages Promotes Boron

We investigated the optimal growth stage for B fertilizer application to improve rice production. The study was conducted using a 2 × 4 factorial design in a randomized complete block during the rainy season of 2022.

Effects of boron application rate on double

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.

Correct Methods for Using Boron Fertilizer During the Flowering Period

The optimal periods for applying boron fertilizers in tomato cultivation are the seedling stage, flowering stage, and fruit enlargement stage. Targeted use during these phases ensures efficient nutrient uptake and enhances productivity.

Rapeseed (scientific name: Brassica napus), also known as rape or green vegetable stalk, is an important oil crop and vegetable. The use of boron fertilizer plays a crucial role in improving yield and quality during rapeseed cultivation. Below is a detailed introduction to boron fertilizer application at different growth stages of rapeseed.

I. Seedling Stage (From Sowing to Emergence)

1. Role of Boron: Boron is one of the essential microelements for plant growth and development, significantly impacting root development, stem growth, and leaf photosynthesis in rapeseed. Applying boron at this stage promotes robust root systems, enhances stress resistance, and improves survival rates.
2. Application Methods: Boron can be applied via foliar spraying in solution form or mixed with soil as a basal application. For foliar spraying, choose sunny weather, dilute the boron solution, and apply evenly on leaves, avoiding contact with stems to prevent burning.
3. Precautions: Avoid excessive boron application during the seedling stage to prevent excessive growth, which may affect later seed setting. Ensure proper combination with other fertilizers to maintain nutritional balance.

II. Tillering Stage (From Emergence to Early Flowering)

1. Role of Boron: A critical period for rapeseed growth, boron application here promotes balanced root and stem development, increases effective tillers, and improves seed setting rates.
2. Application Methods: Boron can be applied through foliar spraying or basal application. For basal application, mix borax with organic fertilizers, spread in the field, and incorporate into the soil. Follow similar foliar spraying methods as in the seedling stage.
3. Precautions: Control boron dosage to avoid excessive growth. Combine with other fertilizers like nitrogen and phosphorus to meet overall nutritional needs throughout the growth period.

III. Flowering Stage (From Early Flowering to Maturity)

1. Role of Boron: Crucial for yield formation, boron application enhances flower organ development, pollen viability, and seed setting rates.
2. Application Methods: Apply boron via foliar spraying or basal application. For foliar spraying, perform after morning dew dries to minimize leaf damage. Basal application involves mixing borax with organic fertilizers, spreading, and soil incorporation.
3. Precautions: Monitor boron usage to prevent overgrowth. Balance with nitrogen, phosphorus, and other fertilizers to ensure comprehensive nutrient supply.

IV. Maturity Stage (Before Harvest)

1. Role of Boron: Key for seed filling, boron promotes seed development, enhancing quality and yield.
2. Application Methods: Apply through foliar spraying (after dew dries) or basal application (mixing borax with organic fertilizers and soil incorporation).
3. Precautions: Regulate boron amount to avoid overgrowth. Maintain balanced fertilization with other nutrients.

Summary: Boron application varies across different growth stages of rapeseed. While seedlings benefit from foliar or basal applications, tillering, flowering, and maturity stages also utilize these methods. Adjust boron usage and methods flexibly according to growth stages and soil conditions to achieve optimal fertilization effects.
