1、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).

2、Frontiers

Diammonium phosphate was adopted as the phosphate fertilizer and applied as the base fertilizer. Urea was used as nitrogen fertilizer, and 90 kg N ha −1 of basal fertilizer was applied to both monoculture and intercropping peanut at once.

3、Impact of Various Organic Fertilizers on the Growth, Yield, and Soil

ent crops, including soybean, maize, and peanut, which all show significant decreases in agronomic traits under continuous cropping conditions [18, 19]. Under equal nitrogen or nutrient content, the use of organic fertilizer can significantly improve the physical and chemical properties of the soil compared to chemical fertilizer, and the ...

Is Using Only Phosphate Fertilizer Sufficient for Peanut Cultivation?

Peanut seedlings need less fertilizer, but if the application of base fertilizer is insufficient or no base fertilizer is applied and summer peanuts are planted, nitrogen fertilizer should be properly applied to promote seedling emergence and flower bud differentiation.

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

All treatments received nitrogen fertilizer at a rate of 72 kg N per hectare. Nitrogen dose was applied using ammonium sulphate 15 N labeled of 10% atom excess from the peanut.

Optimal Fertilizer for Growing Peanut: What You Need to Know

Primarily, Peanut plants require phosphorus and potassium to strengthen root growth and overall plant vitality. While they can fix atmospheric nitrogen due to their symbiotic bond with Rhizobium bacteria, they might need extra nitrogen early on before nitrogen-fixing nodules form.

How to Choose and Apply the Right Peanut Fertilizer

Peanuts are a valuable field crop, but successful cultivation requires a highly specific fertilization program. As a legume, the peanut plant converts atmospheric nitrogen into a usable form through a symbiotic relationship with Rhizobium bacteria in its root nodules.

Magnesium fertilizer application increases peanut growth and pod yield

This study investigated the effect of magnesium application on peanut growth and yield under two nitrogen (N) application rates in acidic soil in southern China.

Peanut fertilizer regulation and fertilization program

About 1 part of sulphur is required for each assimilation of 15 parts of nitrogen. Most of the nitrogen absorbed by peanuts comes from the nitrogen fixation of rhizobium, which accounts for about 70%. The application of phosphate fertilizer can promote the symbiotic nitrogen fixation of rhizobium.

Increasing Calcium and Decreasing Nitrogen Fertilizers Improves Peanut

Peanuts have a high demand for nitrogen fertilizer; proper nitrogen management is a key agronomic factor for improving peanut yields.

Peanuts, an indispensable ingredient in our daily diet, not only boast delicious flavors but also offer exceptional nutritional value. When discussing the fertilizing effects of peanuts, we must first clarify whether they belong to nitrogen or phosphate fertilizers.

I. Nutritional Composition of Peanuts

1. Protein Content: Peanuts are rich in protein, containing approximately 35 grams of protein per 100 grams. Protein is essential for building human cells and maintaining normal physiological functions.
2. Fat Content: Peanuts have a relatively high fat content, with about 48 grams of fat per 100 grams. Fat serves as a critical energy source and a carrier for fat-soluble vitamins (e.g., vitamin A, D).
3. Carbohydrate Content: The carbohydrates in peanuts are primarily starch, with about 67 grams per 100 grams. Carbohydrates are the body’s main energy source and constitute cell walls and bones.
4. Mineral Content: Peanuts contain minerals like calcium, iron, and zinc, which play vital roles in growth and immune system function.
5. Vitamin Content: Peanuts are rich in vitamins, including vitamin E and B-group vitamins, which significantly promote health.

II. The Relationship Between Peanuts and Nitrogen Fertilizers

1. Definition of Nitrogen Fertilizers: Nitrogen fertilizers contain nitrogen, which promotes plant growth by providing this essential element. Nitrogen is crucial for chlorophyll synthesis, protein production, and photosynthesis.
2. Interaction Between Peanuts and Nitrogen Fertilizers: Although peanuts lack nitrogen, their high protein content can be partially absorbed by humans. this absorption is negligible and has no significant impact on plant growth. Thus, peanuts cannot be classified as nitrogen fertilizers.
3. Mechanism of Nitrogen Fertilizers: Nitrogen enhances leaf growth, photosynthesis, and overall plant yield and quality.
4. Application of Nitrogen Fertilizers: Typically applied as nitrogen gas or through organic/chemical fertilizers, nitrogen is converted into ammonia or other forms for plant absorption via microbial decomposition.

III. The Relationship Between Peanuts and Phosphate Fertilizers

1. Definition of Phosphate Fertilizers: Phosphate fertilizers contain phosphorus, which supports plant growth. Phosphorus is essential for root development, fruit maturation, and disease resistance.
2. Interaction Between Peanuts and Phosphate Fertilizers: While peanuts lack phosphorus, their protein content can be minimally absorbed by humans. This absorption is insufficient to impact plant growth, so peanuts are not phosphate fertilizers.
3. Mechanism of Phosphate Fertilizers: Phosphorus strengthens roots, improves water/nutrient absorption, and promotes flowering and reproduction.
4. Application of Phosphate Fertilizers: Phosphates are applied in soil as salts, converted into absorbable forms via microbial action, or supplemented through organic/chemical fertilizers.

IV. The Relationship Between Peanuts and Potash Fertilizers

1. Definition of Potash Fertilizers: Potash fertilizers contain potassium, which enhances plant resilience, water retention, and photosynthesis.
2. Interaction Between Peanuts and Potash Fertilizers: Peanuts lack potassium, but their protein can be minimally absorbed by humans. This absorption is negligible for plant growth, so peanuts are not potash fertilizers.
3. Mechanism of Potash Fertilizers: Potassium strengthens roots, improves nutrient uptake, and boosts flowering and reproduction.
4. Application of Potash Fertilizers: Potash is applied as salts, converted into absorbable forms via microbes, or supplemented through organic/chemical fertilizers.

V. Comprehensive Analysis of Peanuts’ Fertilizing Effects

1. Nutritional Profile: Peanuts are rich in protein, fat, and carbohydrates, providing essential energy and building materials for human health.
2. Nitrogen-Phosphate-Potash Relationship: Peanuts lack nitrogen, phosphorus, and potassium but offer indirect benefits through protein absorption. these effects are too minor to substitute for actual fertilizers.
3. Peanuts are neither nitrogen, phosphate, nor potash fertilizers. They are primarily a protein-rich food. While nutritious for humans, they cannot replace specialized fertilizers in agriculture. For healthy crop growth, selecting appropriate fertilizers based on plant needs remains essential.

Final Note: Peanuts serve as a valuable dietary component but lack the chemical properties required to act as fertilizers. Proper agricultural practices should rely on scientifically formulated nutrients rather than food-based substitutes.
