Agronomic Performances and Nutritional Value of C. olitorius in Burkina Faso

Abstract

Jute mallow (C. olitorius) is a traditional leafy vegetable from Africa and Asia. The richness of its leaves in nutritional elements such a (iron, zinc, potassium and beta carotene) makes it an excellent nutritional supplement for pregnant women and children. It is one of the most important leafy vegetable consumed in Burkina Faso. However, leaf biomass yields remain low and production is still unable to meet the increasing demand. Therefore, the study aims to evaluate the agronomic performances of four morphotypes identified during our previous studies. It will be also question to evaluate their biochemical composition and to study the relationship between agronomic and biochemical traits. Four morphotypes were evaluate agronomical according to Fisher block design using 12 quantitative traits. Fresh leaves of each morphotype were then used for determination of beta-carotene content and mineral element content.The results of the study showed great variability in the agronomic performance and biochemical composition of the four morphotypes. The morphotype (SBL1) with green and shiny leaves expressed the best performance in biomass and number of primary branches as well as in nutritional elements such as iron, potassium and beta carotene. This morphotype could be used as a breeding parent in an extension program for the valorization of this leafy vegetable.
