Predicting the adoption of improved cassava varieties in Sierra Leone

Abstract

In Sierra Leone cassava plays a major role in households' food and income security. Plant breeders have concentrated on improved varieties with an increasing yields per unit area. This study was designed to identify factors that influence adoption or rejection of improved cassava cultivars by growers. Data were collected using questionnaires, focus group discussions and field walks; locations were selected using multistage stratified random sampling. Logistic regression was used to model uptake of improved varieties. Most farmers usually grow several cultivars and just over half have included an improved variety. Of the six improved varieties released in 2005 by the Sierra Leone Agricultural Research Institute, only SLICASS 4, was widely adopted and three were not recorded in the study. Preferred characteristics are; high yield, sweet taste, early maturity and good cooking quality. Cultivars are more likely to be adopted where; cassava is a major crop, households are experienced in cultivating cassava, they have access to research, contact with extension agents and access to cassava markets. Improved cultivars are less likely to be adopted by small households with few resources. Cassava breeders should recognize what farmers find desirable but success will depend on; communicating research, having active extension agents and good access to markets.

Use of Biotechnology in Improving Crop Yields and Sustainability in South Africa

“…In Nigeria, another sub-Saharan economy, the promotion of improved crop varieties has been crucial for enhancing crop yields. A study by (Adesina, 2019) highlights the adoption of improved cassava varieties through agricultural extension services. These varieties are disease-resistant and have led to significant yield increases in cassava, a staple crop in Nigeria.…”
