Sweet Potato Field Management and Fertilization Guidelines

1、Sweetpotato Production and Management

Development workers need to know the degree of commercialisation of sweetpotato and understand gender roles and responsibilities along the sweetpotato value chain. Male and female ownership/ management of sweetpotato fields in most parts of SSA can be grouped into three categories:

2、Effects of Bio and water

To verify an effective approach for alleviating problems associated with the consecutive monoculture of sweet potato, five fertilizer treatments were designed under plastic film-mulched,...

Sweet Potato Fertilization Requirements

Sweet potatoes are tolerant plants to low fertilization and nutrient availability. However, most farmers apply fertilizers to boost their yields for commercial farming.

Sustainable management of sweet potatoes: A review on practices

Genetic breeding can allow their cultivation in challenging environments, such as drylands, as it improves their response to fertilization and irrigation.

This chapter of the North Carolina Organic Commodities Production Guide covers key management practices for organic sweet potato tobacco production.

Sweet Potato Cultivation: A Comprehensive Guide

Optimal soil conditions are essential for maximizing sweet potato yields and quality. Proper soil preparation and fertilization practices play a vital role in creating a favorable environment for root development.

Sweet Potatoes

Avoid fields with high nematode populations and those that had sweet potato in the past two years. Test the soil for nematodes and fertility. Optimum soil pH is 5.8-6.2. If lime is needed, apply it several months before planting. All P and K can be applied before planting.

Frontiers

This study demonstrated that nitrogen fertilization significantly influences soil microbial community structure and enzymatic activities in continuous-cropping sweet potato fields, highlighting its role in shaping the microbiome and soil health.

I. Introduction Sweet potato, as a widely cultivated crop, is rich in nutritional value, containing abundant dietary fiber and various microelements. During its cultivation, reasonable field management and scientific fertilization methods are crucial for improving yield and quality. This article provides a detailed introduction to the basic knowledge and practical techniques of sweet potato field management and fertilization.

II. Sweet Potato Field Management

  1. Land Preparation and Soil Preparation

    • Select suitable land with good drainage to avoid low-lying areas prone to waterlogging.
    • Perform deep tillage (20-30 cm) to improve soil structure, enhance ventilation, and retain moisture.
    • Apply organic fertilizers (e.g., farm manure or compost) to provide essential nutrients.
    • Conduct soil testing to analyze nutrient content and develop an appropriate fertilization plan.
  2. Sowing and Transplanting

    • Choose the sowing time based on the sweet potato variety, typically in April-May for spring planting and August-September for autumn planting.
    • Ensure uniform sowing with consistent row and plant spacing for efficient management.
    • Maintain proper spacing during transplanting (30-50 cm between plants) to allow adequate growth.
  3. Water Management

    • Keep soil moist but avoid waterlogging. Adjust irrigation frequency based on weather and soil humidity.
    • Ensure drainage during rainy seasons to prevent root rot.
    • Supplement irrigation during droughts, especially in early and mid-growth stages.
  4. Pest and Disease Control

    • Regularly inspect plants and address pest/disease signs promptly.
    • Combine biological and chemical control methods to reduce pesticide use and protect the environment.
    • Practice crop rotation to avoid continuous planting disorders.
  5. Harvesting and Storage

    • Harvest mature sweet potatoes promptly to avoid overripening.
    • Dry harvested crops immediately to reduce moisture content and prevent disease.
    • Store in a ventilated, dry area to avoid rot caused by humidity.

III. Scientific Fertilization

  1. Fertilization Principles

    • Follow the principle of "small amounts, multiple applications" to avoid nutrient excess or deficiency.
    • Select fertilizers based on growth stages and soil conditions. For example, use fast-acting nitrogen fertilizers for seedling growth and long-term phosphorus-potassium fertilizers for disease resistance and storage life.
  2. Fertilization Timing

    • Apply base fertilizer immediately after autumn harvest to prepare for spring growth.
    • Topdress with three key applications: seedling fertilizer, flowering fertilizer, and hilling fertilizer, aligned with different growth stages.
  3. Fertilization Rates and Methods

    • Adjust fertilization rates based on soil fertility, plant growth, and weather conditions.
    • Use methods such as furrow application, hole application, or strip application, depending on soil type and fertilization goals.
  4. Precautions

    • Avoid applying fertilizer directly near plants to prevent burns.
    • Do not over-fertilize, especially with nitrogen, to avoid root damage.
    • Irrigate after fertilization to aid absorption and dissolution.

Field management and fertilization of sweet potatoes require systematic adjustments based on growth characteristics and soil conditions. By implementing scientific management and fertilization practices, farmers can significantly improve yield and quality, ultimately enhancing economic benefits.
