1、Effect of Potassium Fertilizer Types and Rates on Peanut Growth and

These contradictory results, and the need to establish solid fertilizer recommendations for the new peanut cultivar LDH.09, have set the objective of the present study - to determine the appropriate K fertilizer type and dose for peanut grown on the saline coastal sandy soils in Binh Dinh.

2、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.

3、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.

4、What Kind Of Fertilizer For Peanuts

Peanuts, being deep-rooted legumes, fix nitrogen themselves and are effective in scavenging phosphorus (P) and potassium (K), leading many to believe they require little fertilizer.

5、Fertilizer application parameters for drip

Scientific fertilization is an important technical means of achieving high and stable peanut yields. Using soil testing and formula fertilization, the "3414" optimal regression design was used and included 14 nitrogen (N), phosphorus (P), and potassium (K) fertilization treatments.

Growing Peanuts – Fertilizers for Peanuts

Balanced Fertility Program: Utilize a fertility program that maintains adequate levels of phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and micronutrients. Soil testing should guide the application rates and timing. Soil test recommendations show 3:1 ratio of Ca to K.

A Guide to Peanut Farming

The balanced use of fertilizer and manure delivers the phosphorus, potassium, calcium, sulphur, and magnesium needed for peanut growth. Before applying fertilizer, it’s important to assess your current soil nutrient status.

What is the Best Fertilizer for Peanuts? Maximize Your Yields

Several types of fertilizers can be used for peanuts, each with its own advantages and disadvantages. These fertilizers contain all three macronutrients (N, P, and K) in various ratios. An example is 10-10-10, which means it contains 10% nitrogen, 10% phosphorus, and 10% potassium.

What is the best fertilizer for peanuts?

Apply sufficient base fertilizer to peanuts before sowing, and apply appropriate compound fertilizer, but do not apply too much phosphorus and potassium fertilizer.

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.

The amount of potassium fertilizer required for peanut cultivation depends on multiple factors, including soil type, climatic conditions, planting density, and the crop’s growth stage. Potassium is one of the essential nutrients for plant growth and significantly impacts peanut development and yield. Below is a detailed guide to determining the appropriate potassium fertilizer dosage, along with recommendations.

1. Soil Testing and Analysis

Conducting a soil test before fertilization is critical. This helps determine the soil’s potassium content and whether supplementation is needed. The process typically involves:

• Sample Collection: Gather soil samples from various locations in the peanut planting area.
• Laboratory Analysis: Send samples to a professional agricultural lab for testing.
• Result Interpretation: Assess whether the soil’s potassium level falls below recommended thresholds.

2. Determining Fertilizer Dosage Based on Soil Potassium Content

If soil tests reveal insufficient potassium (e.g., less than 50 mg/kg), apply approximately 150 kg of potassium fertilizer (60% potassium content) per hectare. For soils with higher potassium levels, reduce the dosage accordingly.

3. Balancing Other Nutrients

In addition to potassium, peanuts require nitrogen (N), phosphorus (P), calcium (Ca), and other nutrients. Ensure balanced soil fertility by:

• Nitrogen: If soil N is low, apply urea (46% N content).
• Phosphorus: For P-deficient soils, use superphosphate (46% P content).

4. Fertilization Methods and Timing

Potassium can be applied as:

• Base Fertilizer: Incorporated into the soil before planting.
• Topdressing: Added during the crop’s growth period.
• Foliar Spraying: Directly sprayed onto leaves for rapid absorption.

Optimal timing includes:

• Early Growth Stage: Apply moderate potassium during seedling establishment.
• Flowering and Pod-Filling Stages: Increase potassium to promote fruit development and enhance yield.

5. Key Considerations and Recommendations

• Avoid Over-Fertilization: Excess potassium can lead to soil salinization and poor crop health. Follow a “less but precise” approach.
• Soil pH Adjustment: In alkaline soils, use sulfur to lower pH and improve potassium uptake.
• Nutrient Synergy: Maintain balanced N-P-K ratios to support full-season growth.
• Monitoring and Adjustment: Regularly test soil nutrients and adjust fertilization based on crop performance and soil conditions.

Rational potassium fertilization for peanuts relies on soil tests, crop requirements, and environmental factors. Scientific fertilization strategies not only ensure healthy growth but also boost yield and quality. Farmers are advised to adopt a holistic approach, integrating soil analysis, nutrient balance, and timely application for optimal results.
