Grow More With Legume IntercroppingMeta Description: Learn how legume intercropping boosts soil fertility, cuts costs, and lifts yields—backed by KARI’s 2025 trials for profitable, sustainable farming. TL;DR: Key Takeaways Legume intercropping improves soil fertility naturally.KARI’s trials show a 20% increase in maize yields.Helps manage fertilizer costs and reduce soil erosion.
Background & Context

Kenyan farmers are increasingly seeking sustainable soil fertility solutions amid rising fertilizer costs and climate stress. This guide trains farmers to implement legume intercropping (e.g., beans with maize) to naturally fix nitrogen, reduce erosion, and boost yields. Evidence from 2025 KARI trials shows intercropped plots had 30% higher soil organic matter and 20% greater maize yields than chemical-fertilizer-only plots.
Key Insights or Strategies
Choosing Compatible Crop Pairs
To maximize the benefits of legume intercropping, select crops that complement each other in fighting pests and nutrients uptake.
Implementing Effective Spacing Techniques
- Plan your field layout to ensure adequate sunlight and air circulation.
- Use strip cropping to alternate rows of legumes and grains.
- Adjust spacing based on crop size and growth patterns.
