1、Optimizing phosphorus rates for peanut: The role of soil P, water

Our findings can help optimize phosphate fertilizer use in tropical sandy soils with low fertility by lowering the current P fertilization recommendation and using peanut cultivars that are more efficient in P acquisition and tolerant to variable water availability.

2、Guide to Fertilizing Your Peanut Plant

Generally, a balanced fertilizer with an N-P-K ratio of 10-10-10 or 14-14-14 is suitable for peanuts. Apply the pre-planting fertilizer evenly across the planting area, making sure to work it into the soil to a depth of 4-6 inches.

3、What is the Best Fertilizer for Peanuts? Maximize Your Yields

A common peanut fertilizer recommendation is to use a fertilizer ratio of 0-1-1 or 0-2-1 (N-P-K). This means no nitrogen, with higher amounts of phosphorus and potassium.

4、What Kind Of Fertilizer For Peanuts

Peanuts, being part of the legume family, naturally fix their own nitrogen, so it’s essential to choose fertilizers with lower nitrogen content, such as a 5-10-10 fertilizer.

5、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.

Peanut fertilizer regulation and fertilization program

Therefore, understanding the fertilizer requirement of peanuts and carrying out scientific fertilization is one of the main measures for producing high-yield and high-quality peanuts. At the moment, it is time for peanuts to use fertilizer, so today we will learn about the rules of peanut fertilizer and organic fertilizer application technology!

What Is the Best Fertilizer for Peanuts? Expert Advice

The best fertilizers for peanuts provide essential nutrients, improve soil fertility, and reduce the environmental impact of peanut production. Farmers should consider using compost-based fertilizers and manure-based fertilizers for optimal peanut yields.

Spring peanuts should be added with phosphate fertilizer

Peanut requires more phosphorus than normal crops and has high absorption and utilization of phosphate fertilizers. Tests have shown that applying 10 kg of calcium phosphate per acre results in significant yield increase, and the aftereffect is obvious.

How can peanuts be fertilized with high yield? When is the best time to

Before the flowering and needling stage, the root system absorbs the strongest fertilizer and absorbs the most fertilizer, so all or most of the fertilizers needed for high-yield peanuts should be combined with winter ploughing and early spring farmland as base fertilizer and seed fertilizer.

Reduce the application of phosphorus fertilizer in peanut fields and

Discussion: Overall, phosphorus-loaded iron-modified biochar reduced the required amount of phosphorus fertilizer, maintain peanut yield, and enhanced phosphorus fertilizer utilization efficiency.

Peanuts are one of the world's most important oil crops, valued for their high nutritional and economic benefits, making them a critical component of agricultural production. To ensure optimal growth and high yields, scientific fertilization is essential. Phosphate fertilizer, one of the three primary nutrients required by plants, plays a vital role in peanut development. Below is a detailed guide to phosphate fertilizer ratios for peanuts, aimed at helping farmers optimize fertilization practices to improve yield and quality.

I. Phosphorus Requirements of Peanuts

Peanuts have the highest demand for phosphorus during the seedling and flowering-fruiting stages. Phosphate fertilizer promotes root growth, enhances water and nutrient absorption, and improves stress resistance and disease tolerance. Additionally, adequate phosphorus supports bud differentiation, increases flowering and fruiting rates, and boosts per-plant productivity. Thus, consistent phosphorus supply is crucial throughout the peanut lifecycle.

II. Phosphorus Demand Across Growth Stages

1. Seed Germination Stage: Phosphorus needs are minimal at this stage, as seeds rely on internal nutrients. slight phosphate application can improve germination rates.

2. Seedling Growth Stage: Phosphorus demand increases gradually. This is a critical period for phosphate application, as it supports root development and stress resistance.

3. Flowering-Fruiting Stage: Phosphorus requirements peak here. Adequate phosphate fertilizer ensures bud differentiation, increases flower and fruit counts, and enhances yield.

4. Maturity-Harvest Stage: Phosphorus needs decrease, but proper application improves seed quality, such as kernel plumpness and oil content.

III. Optimal Phosphate Fertilizer Ratios

Based on peanut growth patterns and phosphorus demands, it is recommended to apply phosphate-rich fertilizers like diammonium phosphate (NPK=5-10-10) or compound fertilizer (NPK=8-12-12). The specific dosage depends on soil fertility, peanut varieties, and planting timing. Generally, 20–30 kg per mu of diammonium phosphate or compound fertilizer meets the needs of most growth stages.

IV. Fertilization Methods

1. Basal Application: Spread phosphate fertilizer evenly on the soil surface before planting and incorporate it into the soil. Suitable for large fields.

2. Topdressing: Apply additional phosphate fertilizer during growth stages based on plant conditions and soil fertility. Ideal for small-scale farms.

3. Mixed Fertilization: Combine phosphate fertilizer with nitrogen and potassium fertilizers to improve efficiency and reduce environmental impact. Suitable for crop rotation or intercropping systems.

V. Key Considerations

1. Avoid Overapplication: Excessive phosphate can lead to soil acidification, salinization, and hinder growth. Use precise amounts.

2. Balance with Nitrogen and Potassium: Combining phosphate with nitrogen (e.g., urea) and potassium (e.g., potassium sulfate) enhances nutrient uptake and lowers costs.

3. Soil-Specific Adjustments: Soil types affect phosphorus availability. Choose fertilizers and dosages based on soil tests (e.g., pH, nutrient levels).

4. Climate Impact: Drought or extreme heat reduces phosphorus efficacy. Adjust strategies accordingly.

5. Monitor Soil Health: Regularly test soil pH and nutrient levels to guide rational fertilization.

Peanuts require concentrated phosphorus during seedling and flowering-fruiting stages. Scientific fertilization ratios and methods significantly boost yield and quality. Prioritize moderate application, balance with other nutrients, and tailor strategies to soil and climate conditions to ensure healthy peanut growth.
