Good Agronomic Practices for Soybean Production: A Package for Enhanced Yields across the Value Chain

Practical knowledge for profitable soybean farming!

This set of Good Agricultural Practices (GAPs) for soybean production aimed at strengthening smallholder resilience, improving productivity, and promoting sustainable and safe food systems. The GAPs focus on sustainable soil fertility management through nitrogen fixation and targeted fertilizer use, alongside crop rotation and integration of soybean into cereal-based systems. They also promote efficient resource use, environmentally friendly practices such as minimum tillage and residue retention, and safe management of pests and diseases. It includes guidance on harvesting, drying, storage, and basic processing methods to reduce losses, improve quality, and support local value addition.

This technology is pre-validated.

Farmer climate change readiness: Significant improvement

It helps farmers in resolving climate challenges

Biodiversity: Positive impact on biodiversity

This helps improve nature, with most positive impacts on plants and animals being a good source of protein for animal feeds

Soil quality: Improves soil health and fertility

The crop on its own helps ameliorate the soil health and fertility by fixing more of atmospherics nitrogen into the soil for the benefit of the plants, soil microbes and soil organism

Problem

  • Limited farmer capacity to adopt climate-smart agricultural practices, particularly in soybean production systems.
  • Low dissemination of research-based technologies developed through research-for-development programs.
  • Declining soil fertility and unsustainable farming practices in areas with intensive cereal cultivation.
  • Limited implementation of Good Agricultural Practices (GAPs) that ensure food safety and environmentally sustainable production.
  • Insufficient integration of legumes in farming systems, despite their potential to improve soil nitrogen and support crop rotation systems.
  • Limited farmer knowledge on post-harvest handling and storage, which affects grain quality and marketability.

Solution

  • Build farmer capacity in climate-smart practices through structured training on resilient soybean varieties, inoculants, and GAPs.
  • Facilitate adoption of research-based technologies by providing hands-on demonstrations and practical modules.
  • Promote sustainable agriculture via crop rotation, residue retention, and integration of legumes into cereal-based systems.
  • Enhance food safety and environmental sustainability by implementing GAPs across production and post-harvest stages.
  • Improve post-harvest handling and storage to maintain grain quality, ensure marketability, and reduce losses.
  • Strengthen resilience and productivity of smallholder farming systems by integrating soybean into diversified cropping systems.

Key points to design your program

These GAPs for soybean production are structured, capacity-building intervention that strengthens soybean-based farming systems by promoting climate-smart practices, improved productivity, and sustainable resource management. It contributes to key Sustainable Development Goals (SDGs), including SDG 2 by increasing food production and access to plant-based protein; SDG 1 by improving farmer incomes; and SDG 13 through sustainable soil management and nitrogen fixation.

To successfully integrate this approach into a development program, the following prerequisites should be considered:

  1. Define target beneficiaries and delivery structure

    • Identify target farmer groups (e.g., smallholders, cooperatives) and define the number of extension agents or facilitators required to ensure effective training and outreach.

  2. Establish partnerships with technical institutions

    • Collaborate with research organizations (e.g., IITA) and local implementing partners to access validated training modules, technical expertise, and field support.

  3. Allocate adequate financial resources

    • Budget for training delivery, demonstration plots, extension services, inputs, monitoring activities, and knowledge dissemination.

  4. Integrate awareness and community engagement strategies

    • Conduct sensitization campaigns to ensure farmers understand the benefits of soybean production, good practices, and participation in the program.

  5. Ensure access to inputs and enabling services

    • Facilitate availability of improved seeds, inoculants, fertilizers, and advisory services to support adoption at scale.

  6. Design monitoring, learning, and scaling mechanisms

    • Establish systems to track adoption, measure impact (productivity, income, soil fertility), and support scaling through farmer networks and institutional learning.

Scaling Readiness describes how complete a technology’s development is and its ability to be scaled. It produces a score that measures a technology’s readiness along two axes: the level of maturity of the idea itself, and the level to which the technology has been used so far.

Each axis goes from 0 to 9 where 9 is the “ready-to-scale” status. For each technology profile in the e-catalogs we have documented the scaling readiness status from evidence given by the technology providers. The e-catalogs only showcase technologies for which the scaling readiness score is at least 8 for maturity of the idea and 7 for the level of use.

The graph below represents visually the scaling readiness status for this technology, you can see the label of each level by hovering your mouse cursor on the number.

Its supports biological nitrogen fixation, reducing reliance on synthetic fertilizers and improving environmental sustainability.

1. Site Selection and Land Preparation

  • Choose well-drained sandy loam soils; avoid waterlogged areas.
  • Clear land manually or with herbicides (e.g., glyphosate).
  • Plough and harrow for good soil structure, or adopt minimum/zero tillage where appropriate.

2. Variety Selection

  • Select improved, climate-adapted varieties suited to your agro-ecological zone.
  • Consider:
    • Maturity period
    • Yield potential
    • Drought tolerance
    • Pest and disease resistance

3. Seed Preparation and Planting

  • Use quality seeds .
  • Treat seeds with fungicide (unless inoculated).
  • Apply inoculant (e.g., NoduMax) to enhance nitrogen fixation.
  • Plant at:
    • Spacing: ~50–60 cm between rows, 5 cm within rows
    • Depth: 2.5–5 cm
  • Plant at the right time, aligned with rainfall and variety maturity.

4. Soil Fertility Management

  • Soybean requires low nitrogen (starter dose ~15 kg/ha if needed).
  • Apply phosphorus (≈30 kg/ha SSP) to support nodulation and growth.
  • Use inoculants to improve nitrogen fixation and increase yields.

5. Cropping System Practices

  • Practice crop rotation (e.g., with maize, millet, sorghum) to improve soil fertility and reduce pests.
  • Use intercropping systems where appropriate.
  • Retain crop residues or use mulching to improve soil health.

6. Weed Management

  • Control weeds early, as soybean is a weak competitor.
  • Options include:
    • Manual weeding (2, 4–5, and 7–8 weeks after planting)
    • Herbicides (pre-planting or post-emergence)
  • Maintain a clean field to prevent yield loss.

7. Pest and Disease Management

  • Use resistant varieties and clean seeds.
  • Apply:
    • Crop rotation
    • Seed dressing
    • Fungicides or insecticides when necessary
  • Remove and destroy infected plants.

8. Harvesting

  • Harvest when:
    • Pods are dry
    • Leaves have fallen
  • Cut plants at ground level (do not uproot).
  • Thresh manually or mechanically.

9. Post-harvest Handling and Storage

  • Dry grains properly.
  • Clean and store in:
    • Airtight or polythene bags (for seeds)
    • PICS bags (for grain)
  • Keep in a cool, dry, and clean storage environment.
