Corchorus olitorius is an indigenous leafy vegetable which is widely consumed in Africa and Asia. In order to investigate agronomic practices, agromorphologic diversity and ethanobotanic knowledge of producer, present
study has been carried out in the four agro-climatic zones of Burkina Faso. During this study, total 178 accessions were collected, among these 111 accessions were characterized on the basis of 17 well identified qualitative (5) and quantitative (12) characteristics. Results of study revealed that most of the identification characteristics and terminology used for identification of C. olitorius is based on the visible phenotypic characteristics. Two most common morphotypes which was identified during the study was “bulvank yanga” and “bulvank moaga or bulvank raogo". All the identified 111 accessions were divided in four groups. Among these groups 1 have eighteen accessions (18) which were characterized by poor performing and late growing individuals with weak stem and leaves outputs. While groups 2 and 3 are represented by 33 and 42 accessions respectively these were characterized by individuals with average performance. Group 4 is made up of eighteen (18) accessions, characterized by individuals with cycle precocious semi-flowering and very high morphological performances (PEL, FWL, FWS and DIS). Most of the ethamobotanic knowledge is based on the traditional and phenotypical knowledge which they gained from their ancestors..
