Varietal diversity as a lever for cassava variety development: exploring varietal complementarities in Cameroon

Area of Science:

• Agricultural Science
• Agronomy
• Plant Breeding

Background:

• Cassava is vital for Cameroonian smallholder farmers, yet production lags behind potential.
• Developed cassava varieties focus on yield and disease resistance but face low adoption rates.
• Dissemination challenges necessitate a broader examination of the cassava production system.

Purpose of the Study:

• To analyze varietal complementarity as a strategy for optimizing cassava variety use by farmers.
• To understand the determinants of adoption and effective dissemination of improved cassava varieties.

Main Methods:

• Conducted 111 semi-structured interviews with farmers in Central and Eastern Cameroon.
• Utilized purposive sampling in four villages where improved cassava varieties were disseminated.
• Analyzed farmer practices related to cassava varietal selection and use.

Main Results:

• Identified four types of varietal complementarity: use, crop management, risk management, and cultural.
• Varietal complementarity is a key strategy employed by farmers in Cameroon.
• These practices influence the adoption and continuous use of cassava varieties.

Conclusions:

• Varietal complementarities practiced by farmers should be integrated into research and development programs.
• This integration can lead to more effective breeding and dissemination approaches for cassava.
• Optimizing breeding and dissemination requires understanding farmer-centric varietal strategies.
