Agriculture and Innovation in Zambia
Agriculture is the backbone of Zambia’s economy and rural livelihoods. But smallholder farmers often face drought, poor soil, and unpredictable markets. At Monana Organic Limited, we promote proven techniques like intercropping to help farmers grow more sustainably and profitably.
What Is Intercropping?
Intercropping means planting two or more crops on the same land at the same time. Unlike monocropping, intercropping creates crop diversity, improves land efficiency, and makes better use of available resources.
Farmers in Zambia have practiced intercropping for decades — especially with maize — but new research shows even greater benefits when sunflowers are included.
For example, intercropping sunflower and maize improves total yields by leveraging sunflower’s pest resistance and maize’s productivity (Lithourgidis et al., 2011).
Benefits of Intercropping with Sunflowers
Economic Advantages
Research shows that intercropping sunflowers with soybeans, maize, groundnuts, or beans can significantly improve income. For instance:
- Intercropping sunflower with soybeans increased yield by up to 58% compared to monocropping (Olowe & Adebimpe, 2009).
- Diversifying crops also buffers farmers against market fluctuations, as one crop can compensate if another performs poorly.

Improved Soil Fertility
Sunflowers’ deep taproots break up compacted soils and draw nutrients from deeper layers. This enhances:
- Water retention
- Nutrient access
- Microbial life in the soil
When paired with nitrogen-fixing legumes like soybeans or beans, soil quality improves even more — reducing the need for chemical fertilizers (De La Fuent et al., 2014).
Pest & Disease Control
Sunflowers attract beneficial insects such as ladybugs and lacewings that:
- Prey on common pests like aphids
- Reduce the need for pesticides
- Improve crop health naturally
Intercropping creates a more complex plant environment, disrupting pest life cycles and encouraging natural pest suppression (De La Fuent et al., 2014).
Biodiversity and Stability
Greater crop diversity increases system resilience and lowers risk. Intercropping sunflowers:
- Increases genetic and ecological diversity
- Protects against total crop failure
- Enhances food and income stability
(De La Fuent et al., 2014)
Nutrition and Food Security
Sunflowers provide Vitamin E and healthy oils. When intercropped with legumes and greens, they contribute to:
- More balanced diets
- Better household nutrition
- Enhanced food security for rural families
Sustainable Agriculture
By reducing inputs, boosting soil health, and promoting biodiversity, intercropping with sunflowers supports:
- Climate-smart agriculture
- Long-term sustainability
- Lower farming costs
This aligns with global goals for sustainable food systems and regenerative farming practices.
