1、Applying Boron Fertilizer at Different Growth Stages Promotes Boron

Our recent study found that basal soil B application effectively increased the total B uptake of rice plants in both pot and field experiments, though it had no effect on grain yield (Songsriin et al, 2023).

2、How Much Boron Fertilizer to Use per Mu of Land

The amount of boron fertilizer required per mu of land depends on factors such as soil boron content, crop type, and planting methods. Below is a detailed guide on determining the appropriate boron fertilizer dosage based on these factors.

3、Different Boron Fertilizer Application Methods and Amounts Affecting

The results showed that the basal application of boron fertilizer and combination of basal application and foliar application of boron fertilizer could make rice growth period early, especially full heading stage which was 1-3 days earlier.

4、The Best Fertilizer for Rice Crop: Organic, NPK, and

A common Rice fertilizer application scheme used by a large number of Rice farmers involves 2 major applications for fertilizer: the first application occurs approximately simultaneously with planting or transplanting (or approximately 20).

5、Boron in fertilizer applications

To determine the optimum rate and method of applying sufficient boron for optimum yields, growers need to know the relative boron needs for their crops. When tested for spreadability, Granubor was consistent in every fertilizer spread tested.

Applying Boron Fertilizer at Different Growth Stages

展开更多 Boron (B)is an essential micronutrient for plant growth and yield.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.We utilized two premium Thai rice varieties Khao Dawk ...

How Much Boron Fertilizer Should Be Applied per Spray?

Boron fertilizer application rates vary depending on the crop, soil type, and existing boron levels. It is essential to consult soil test results and crop-specific recommendations for determining the appropriate boron application rate.

Boron in Soils and Plant Nutrition

This method of B application is popular due to the convenience of mixing the desired amounts of B with fluid fertilizers just before application in the field. There are no segregation problems with fluids, so uniformity of application is easily achieved.

How Much Mai Boron Fertilizer Water is Needed per Mu?

On boron-deficient soil, 0.5-1 kg of boron fertilizer can be applied per mu. Fertilizer effect usually lasts for 3-5 years; when making seed fertilizer, you can soak seeds with 0.01%-0.1% borax or boric acid aqueous solution for 6-12 hours.

Boron nutrition of rice in different production systems. A review

Most rice-based cropping systems, including rice–wheat, are facing B deficiency as they are often practiced on high pH and alkaline soils with low B contents, low soil organic matter, and inadequate use of B fertilizer, which restricts the availability, uptake, and deposition of B into grains.

In agricultural production, boron fertilizer is a critical nutrient that plays a vital role in crop growth and development. For rice, proper boron application can promote root development, enhance disease resistance, and increase yield. rational use of boron fertilizer is essential for improving rice productivity and quality. Below are some recommendations for determining the appropriate basal boron fertilizer rate in rice:

1. Determine Soil Boron Content: Before applying boron fertilizer to rice, assess the soil’s boron levels through soil testing. This provides a precise reference for fertilization. If soil boron is low, increase the dosage; if high, reduce it accordingly.

2. Select Boron Fertilizer Based on Rice Variety: Different rice varieties have varying boron requirements. Choose fertilizer suited to the variety’s characteristics. Generally, low-boron rice varieties require higher boron rates, while high-boron varieties need less.

3. Timing of Application: Boron demand varies across rice growth stages. Higher rates are typically needed during the tillering and booting stages, while reduced amounts are applied during heading and maturity.

4. Application Method: Basal application is the most common method. Broadcast boron evenly over the field, followed by plowing and planting. Avoid excessive rates to prevent waste, and ensure boron does not directly contact seeds, as this may reduce germination.

5. Dosage: There is no universal standard for basal boron application in rice. Generally, 0.5–1 kilograms (kg) of borax or boric acid per mu (approx. 0.067 hectares) is recommended. Adjust this based on soil boron content, rice variety, and growth stage.

6. Precautions:

   • Use high-quality boron fertilizer to avoid inferior products.
   • Follow correct application methods to prevent over- or under-fertilization.
   • Avoid direct contact with seeds to protect germination rates.
   • Monitor rice growth and adjust fertilization strategies as needed.

the optimal basal boron rate for rice depends on soil conditions, rice variety, and growth stage. By managing these factors effectively, farmers can achieve economical and efficient fertilization, boosting yield and quality while increasing income.
