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 are designed to improve national agricultural productivity, ensure food safety, and promote sustainable farming systems. It integrates proven practices across the full production cycle, including site selection, use of improved and climate-smart varieties, land preparation, optimal planting, and efficient input use. The GAPs promote soil fertility restoration through biological nitrogen fixation and appropriate fertilizer use, while encouraging crop rotation to support long-term soil health. They also include effective weed, pest, and disease management, as well as environmentally responsible practices such as minimum tillage and safe use of agro-inputs. It ensures proper harvesting and post-harvest handling to maintain grain quality and meet market standards, while supporting value addition through basic processing of soybean into food products.

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

  • Low agricultural productivity due to limited farmer knowledge of improved soybean varieties and recommended agronomic practices.
  • Declining soil fertility in many farming systems, particularly where cereals such as maize, millet, and sorghum are grown continuously.
  • Weak dissemination of proven agricultural technologies, including improved varieties, inoculants, and good agricultural practices.
  • Food safety concerns due to poor on-farm production and post-production practices that may lead to contamination or unsafe food products.
  • Limited farmer capacity to produce market-quality soybean, affecting competitiveness in domestic and export markets.

Solution

  • Enhance farmer knowledge through structured training on improved soybean varieties and recommended agronomic practices.
  • Promote soil fertility improvement via crop rotation, residue retention, and use of inoculants like NoduMax for biological nitrogen fixation.
  • Increase availability of plant-based protein by boosting soybean production for food and fodder.
  • Strengthen technology dissemination by linking research-based solutions with farmer training programs.
  • Improve food safety and market readiness through adoption of Good Agricultural Practices (GAPs) during production and post-harvest handling.
  • Support production of market-quality soybean via training on proper planting, harvesting, drying, and storage techniques.

Key points to design your project

These GAPs for soybean production are field-oriented capacity-building method designed to equip soybean farmers with practical knowledge on improved varieties, good agronomic practices, and post-harvest management to increase productivity, quality, and sustainability.

To ensure successful integration into your project, the following prerequisites should be considered:

  1. Define target scale and human resources

    • Identify the number of soybean farmers to be trained and determine the required number of advisory/extension agents to ensure effective delivery and follow-up.

  2. Establish technical partnerships

    • Engage with the IITA soybean team and relevant partners to access validated training content, technical expertise, and training materials.

  3. Plan and allocate training budget

    • Anticipate and budget for all training-related costs, including training sessions, materials, logistics, demonstration plots, and technical supervision.

  4. Conduct awareness and mobilization activities

    • Sensitize farmers and stakeholders on the objectives, benefits, and expected outcomes of the training to ensure strong participation and adoption.

  5. Ensure availability of key inputs and technologies

    • Facilitate access to improved soybean varieties, inoculants (e.g., NoduMax), fertilizers, and basic equipment required for effective adoption of practices.

  6. Set up demonstration and follow-up mechanisms

    • Establish demonstration plots and provide continuous advisory support to reinforce learning, monitor adoption, and ensure sustained impact.

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.

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.
