Groundnut production constraints, farming systems, and farmer-preferred traits in Tanzania

ABSTRACTGroundnut (Arachis hypogaea L.) production in Tanzania is affected by a multitude of biotic and abiotic stresses and socioeconomic constraints. The objective of this study was to document the groundnut farmers’ major production constraints, farming systems, and varietal trait preferences in selected agroecologies of Tanzania. A participatory rural appraisal study was conducted in three groundnut-producing zones: Lake, Central, and Southern. Data were collected from 170 groundnut farmers using a semistructured questionnaire, focus group discussions, and field observations. The production constraints were mainly diseases and pests, which were reported by 87.7% and 84.9% of respondents, respectively. Groundnut rust, caused by Puccinia arachidis Speg, was the major cause of yield reduction, as reported by 30% of the respondents. Drought stress and nonavailability of seed of improved varieties were other important constraints, as reported by 83.9% and 76.1% of the respondents, respectively. Groundnut a...
