In this article, we have compiled a list of the 12 best fertilizers for sweet potatoes that can help you achieve optimal growth and yield.

4、Sweet Potato Fertilizer Requirements and Recommendations: Management

One of the best phosphorus fertilizers for sweet potatoes is rock phosphate. It is a natural source of phosphorus and provides a slow-release supply to the plants. Another option is superphosphate, which contains a higher phosphorus concentration and is readily available to the crops.

Fertilizing Sweet Potatoes: What Is The Best Fertilizer?

The ratio of 5-10-10 or 12-12-12 is the best fertilizer for sweet potatoes. The rule of thumb for this task is to pick produce that is low in nitrogen and high in potassium and phosphates.

Effects of Various Potassium Fertilizer Dosages on Agronomic and

To explore the effects of various potassium fertilizer dosages on sweet potatoes, field experiments were conducted in 2018 and 2019 using a randomized block design.

Sweet potato is an important food and vegetable crop, and the root expansion stage in its growth cycle is a critical period for yield formation. During this phase, sweet potato plants have a high demand for nutrients, making rational fertilization essential for improving both yield and quality. As an efficient and convenient method of fertilization, foliar spraying is particularly important during the root expansion stage. Below are recommendations for applying foliar fertilizers during this period:

1. Selection of Foliar Fertilizers

• Nitrogen Fertilizers: Nitrogen promotes plant growth and enhances photosynthetic capacity, supporting overall plant development. During the root expansion stage, appropriate nitrogen application can accelerate root enlargement and increase yields. excessive nitrogen may lead to excessive vegetative growth, reducing quality. Dosage should be carefully controlled.

• Phosphorus Fertilizers: Phosphorus supports root system development, improves stress resistance, and enhances pest/disease resilience. It aids root formation and sugar accumulation, boosting both yield and quality. Avoid overapplication.

• Potassium Fertilizers: Potassium strengthens disease resistance, stress tolerance, and pest management. It also promotes root development and sugar content. Overuse should be avoided to prevent adverse effects.

• Micronutrient Fertilizers: Micronutrients like boron, zinc, and iron are crucial for healthy growth. Boron enhances root formation, zinc improves disease resistance, and iron supports sugar accumulation. Apply in moderation.

2. Timing of Foliar Fertilizer Application

• Before the Expansion Stage: Apply a comprehensive foliar spray to prepare for the upcoming stage. Nitrogen-focused fertilizers support early growth.

• Mid-Expansion Stage: Supplement nutrients with nitrogen-rich formulas to sustain growth and root development.

• Late Expansion Stage: Apply nitrogen-based fertilizers before harvest to ensure optimal nutrient uptake and readiness for harvest.

3. Application Methods

• Dilution Ratio: Follow product instructions or test small batches to determine ideal dilution (e.g., 1:100). Adjust based on plant response.

• Timing: Apply on sunny, calm days between 10:00 AM and 4:00 PM for optimal absorption.

• Target Areas: Spray on the undersides or sides of leaves to minimize evaporation and light blockage. Avoid non-target areas to reduce disease risk.

4. Precautions

• Avoid Overapplication: Excessive use can cause leaf burn, yellowing, or plant death. Adhere to recommended doses.

• Safety Measures: Wear protective gear to prevent skin/eye contact and avoid environmental contamination.

• Monitor Plant Response: Observe leaf color, size, and texture. Adjust applications if abnormalities occur to ensure healthy growth.

scientific foliar fertilization during the sweet potato root expansion stage is key to maximizing yields and quality. Choose fertilizers based on plant needs and soil conditions, follow application guidelines, and prioritize safety to achieve optimal results.
