1、Boron applications for improved peanut quality and yields

The cotyledons are concave and discolored. This damage reduces the quality and value of the crop. Yields and oil content of peanuts also may be reduced. Severe deficiencies of boron which result in visual symptoms are rarely found in peanut producing regions where boron has been previously applied.

2、Effects of Boron and Molybdenum Fertilizer Combined

The results showed that: (1) seed dressing with boron and molybdenum fertilizer was very important for the development of root nodules, and could significantly increase the dry matter accumulation in each part of peanut.

3、Effect of Biochar, Mycorrhiza, and Foliar Application of Boron on

Considering the nutritional benefits of peanuts, the predominantly positive effects of the application of biochar derived from various biomass wastes such as Azolla and peanut shells, we have used these two types of plant sources as raw materials for biochar production in this study.

The results showed that: (1) seed dressing with boron and molybdenum fertilizer was very important for the development of root nodules, and could significantly increase the dry matter accumulation in each part of peanut.

Excessive N applications reduces yield and biological N fixation of

Excessive nitrogen (N) applications are widely used leading to declined N use efficiency (NUE) and biological N fixation (BNF). However, the influence of excessive fertilizer N inputs on yield and BNF of summer-peanut remains uncertain.

Effect of boric fertilizer on peanut absorption of boron and

Field experiments and 15N-labelled micro-plot experiments were carried out to study the effect of B fertilizer on absorption of B and N by groundnuts in Hebei Province in 1991-92. The concentration of B in groundnut plants increased with increasing B fertilizer rate.

Effects of Combined Application with Boron Fertilizer and Molybdenum

[Objective]The research aimed to investigate the effects of B fertilizer and Mo fertilizer and the fertilization methods on the yield of peanut.

Introduction uction must be increased to meet the global food needs of the growing population. This is made possible by intensive use of inputs, particularly chemical fertilizers (Boyd et al. 2020). Chemical fertilizers provide the ele-ments that crops need to grow well, but their excessive use negatively affects soil health, quality, and f

Thus, according to the results of this experiment, proper and balanced nutritional management of peanuts leads to better yields. Foliar fertilization with nano boron can help to increase the...

Effects of long

Soil fertility can deteriorate with the long-term use of NPK fertilizers, resulting in soil acidification, poor soil aggregate stability, and low levels of essential micronutrients.

Excessive boron fertilizer can negatively impact peanuts in the following ways:

1. Growth Retardation: Excessive boron disrupts peanut plant growth because boron is an essential microelement for plant development. Overaccumulation of boron in plants can lead to stunted growth, yellowing leaves, and poor fruit/seed development.

2. Reduced Yield: High boron levels decrease peanut productivity. Growth retardation impairs photosynthesis and nutrient uptake, directly lowering yields. Additionally, excessive boron interferes with flowering and pollination, further reducing output.

3. Declined Quality: Boron excess adversely affects peanut quality. Overly high boron content in seeds may cause bitterness and reduce palatability. It also lowers nutritional value by decreasing protein and fat content in the peanuts.

4. Increased Pest/Disease Susceptibility: Excess boron weakens plants, making them more vulnerable to pests and diseases. Stressed plants attract pathogens and insects, exacerbating infestations.

5. Soil Degradation: Overuse of boron fertilizer disrupts soil ecology. Elevated boron concentrations harm microbial activity, leading to soil acidification, compaction, and long-term reduced fertility.

6. Higher Economic Costs: Excess boron raises production expenses. Lower yields, poorer quality, and increased pest/disease management require additional labor, resources, and inputs.

Mitigation Strategies:

1. Optimize Boron Application: Tailor boron fertilizer doses to soil type and peanut variety. Consult scientific guidelines or agronomists to determine appropriate rates.

2. Precise Fertilization: Monitor plant health and fruit development to adjust boron application. Avoid excessive spreading.

3. Enhance Field Management: Maintain weed-free fields, monitor for pests/diseases proactively, and adopt integrated pest management (IPM) practices.

4. Improve Cropping Systems: Rotate peanuts with other crops or use intercropping to prevent boron buildup in soil.

Excessive boron severely impacts peanut growth, yield, quality, soil health, and profitability. To minimize risks, farmers should apply boron judiciously, prioritize soil testing, employ best agricultural practices, and integrate crop diversity into planting systems.
