1、Response of peanut (Arachis hypogaea L.) plant to bio

Thus, the aim of this study is to evaluate the effect of asymbiotic bacteria Azotobacter sp. and symbiotic bacteria (Bradyrhizobium sp.) on enhancing the nitrogen fixation on peanut yield. Applied plant residues are incorporated to the soil three month prior to peanut cultivation.

2、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.

3、Growing Peanuts – Fertilizers for Peanuts

One of the major benefits of growing peanuts, or any legume is that the crop requires little nitrogen fertilizer. Peanuts are efficient legumes that fulfills its own N requirement through association with specific rhizobium (Bradyrhizobia).

Effect of N, P K, Ca and Mg Fertilizer Application on Peanuts in Tra

Effective management and appropriate use of nitrogen fertilizers in the pod zone present a promising strategy to boost peanut productivity and optimize nitrogen utilization efficiency.

The UGA Peanut Fertilization Strategy … In a Nutshell

Because the peanut plant is a deep-rooted legume that fixes nitrogen and is a good scavenger of “P&K’, most people say it doesn’t need a lot of fertilizer. That is not necessarily true and if you come up short on something like pH or calcium it could really reduce yields and quality.

Nitrogen Fertilizer Early in the Season Peanut Notes No. 72 2020

Question about Applying Ammonium Sulfate to Peanuts Early in the Season. In research from many years ago we found that unless there is a true nitrogen (N) deficiency, there is no value in applying nitrogen fertilizer.

What Type Of Fertilizer Is Best For Peanuts?

Peanuts respond best to residual fertilization that has been applied to the crop preceding peanuts; however, if the area to be planted has not been fertilized during the prior 12 months, then ahead of planting, apply 10 pounds 0-10-20 fertilizer per 1,000 square feet.

What is the Best Fertilizer for Peanuts? Maximize Your Yields

This article provides peanut fertilizer recommendations and explains how to maximize your yields by understanding peanut nutrient requirements and implementing effective peanut nutrient management.

Guide to Fertilizing Your Peanut Plant

Based on the results of your soil test, you can calculate the appropriate amount of fertilizer needed to meet your peanut plant’s requirements. Generally, a balanced fertilizer with an N-P-K ratio of 10-10-10 or 14-14-14 is suitable for peanuts.

Do Peanuts Add Nitrogen to Soil?

Use peanut residues as green manure: Incorporate peanut residues into the soil to act as a green manure, adding organic matter and nitrogen to the soil. Optimize soil conditions: Ensure optimal soil conditions for peanut growth, including adequate moisture, suitable pH, and sufficient nutrients.

Application of Liquid Nitrogen Fertilizer in Peanut Cultivation and Pesticide Residue Issues

I. Introduction to Liquid Nitrogen Fertilizer

Liquid nitrogen fertilizer is a liquid-form nutrient solution with a high concentration of nitrogen, characterized by high nutrient content, rapid absorption, and efficient utilization. As nitrogen is one of the three essential macroelements for plant growth, liquid nitrogen fertilizer is widely used in agricultural cultivation to support crop development.

II. Application of Liquid Nitrogen Fertilizer in Peanut Cultivation

1. Promoting Peanut Growth: Liquid nitrogen fertilizer rapidly provides the nitrogen required by peanuts, accelerating root development and sprouting. This shortens the growth cycle and increases yield.
2. Enhancing Stress Resistance: During growth, liquid nitrogen fertilizer strengthens the plant’s disease and pest resistance, reducing the incidence of pathogens and pests, thereby improving overall health.
3. Improving Soil Structure: Its use enhances soil physical properties, such as aeration and water retention, which benefits root system development.

III. Precautions for Using Liquid Nitrogen Fertilizer

1. Rational Application Rates: Excessive use leads to nitrogen surplus, causing resource waste and environmental issues. The dosage should be adjusted based on peanut growth stages and soil conditions.
2. Avoid Direct Contact with Crops: Due to its volatility, direct contact may burn or damage plants. Use protective equipment like masks and gloves during application.
3. Safe Storage: Store in cool, ventilated areas away from heat sources. Regularly inspect packaging to prevent leaks.

IV. Pesticide Residue Issues

1. Types and Functions of Pesticides: To control pests and diseases, farmers often apply insecticides, fungicides, and herbicides. These protect crops but may leave residues.
2. Hazards of Residues: Improper or excessive use results in residue accumulation in peanuts, posing health risks. Chronic exposure to contaminated food may lead to toxicity or even cancer.
3. Residue Detection Methods: Regulatory agencies test residues via gas chromatography, liquid chromatography, and mass spectrometry to ensure compliance.
4. Residue Mitigation Strategies: Promote low-toxicity, eco-friendly pesticides; strengthen usage regulations; and educate farmers on scientific application. Improved farming techniques can also reduce pest/disease incidence, minimizing pesticide reliance.

Liquid nitrogen fertilizer plays a vital role in peanut cultivation by boosting growth and yields. careful attention to application rates, safety protocols, and storage is critical. While pesticide residues in commercial peanuts are generally low, residual risks persist. Enhanced monitoring, strict management, and consumer awareness are essential to ensuring food safety and public health.
