Cambodian cassava farmers have limited knowledge about how they can improve their yields with fertiliser and pesticides. And because rice is the dominant crop in Cambodia, agricultural input companies have had little incentive to target cassava farmers with their marketing outreach and information services.
Traditionally farmers keep cassava stems from one season to grow in the next due to the lack of formal stem producers. This means that new, improved varieties are not being introduced, and the quality of yields is declining.
