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
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:
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.
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.
Allocate adequate financial resources
Budget for training delivery, demonstration plots, extension services, inputs, monitoring activities, and knowledge dissemination.
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.
Ensure access to inputs and enabling services
Facilitate availability of improved seeds, inoculants, fertilizers, and advisory services to support adoption at scale.
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.

Unintended impacts |
Mitigation measures |
|
Smallholder Farmers with Limited Resources |
· Exclusion risk if farmers cannot afford inputs (improved seeds, inoculants, fertilizers). · Financial strain from adopting recommended practices without guaranteed returns. · Unequal benefits if better-resourced farmers adopt faster. |
· Facilitate access to inputs through subsidies, credit schemes, or group purchasing. · Promote low-cost and phased adoption options (e.g., prioritizing key practices first). · Target support to the most vulnerable farmers through inclusive selection criteria and monitoring. |
|
Women Farmers with low literacy |
· Increased labor burden, especially from manual weeding and farm operations. · Limited participation due to time constraints or restricted access to training sessions. · Risk of reduced control over income as soybean becomes more profitable. |
· Promote labor-saving practices (e.g., improved spacing, appropriate weed control methods). · Ensure inclusive training design (flexible schedules, local delivery, targeted outreach). · Support women’s access to markets and income control, including through group organization. |
|
Farmers in Poor Soil and High-Risk Agro-Ecological Areas |
· Low or variable returns if practices are not well adapted to local conditions. · Adoption failure risk due to climate variability (e.g., rainfall uncertainty). · Over-reliance on recommended inputs without sufficient soil or climate adaptation. |
· Promote locally adapted varieties and context-specific recommendations. · Integrate risk-reducing practices (e.g., crop rotation, early maturing varieties). · Provide continuous advisory support to adjust practices based on local conditions. |
