Participatory evaluation of improved bean varieties
1 like1,069 views
The document outlines a participatory evaluation of improved bean varieties focusing on pathogen resistance and water stress in the context of erratic rainfall and climate challenges. Farmers utilize both guided and traditional practices to monitor plant health, development, and crop performance, resulting in increased bean consumption and reduced costs for families. The study emphasizes the importance of adaptation and food security through sustainable agricultural practices.

Climate challenge Evaluation of improved climbing beans varieties on pathogen resistance and water stress, as well as biofortified bush beans varieties. The evaluation is done in the farm where the farmer implements both guided and traditional practices. The farmer registers plant development, crop performance and pests and diseases appearence in addition to climate monitoring, in order to provide feedback to the researcher. The practice emphasizes adaptation, food security and productivity, although the minimal management of agrochemical inputs also contributes to the mitigation pillar.
