ABSTRACT
Background: Costus afer grows on different soil terrains such as elevated and regular soil terrain, which may influence the biochemical composition of this important medicinal plant. Objectives: This study was designed to evaluate the mineral nutrients and proximate contents of Costus afer as well as the soil quality of the hilly area of the study area. Methods: A plot of about 30m x 30m was selected on a dried hilly area of Yenagoa, alongside a regular terrain. Leaf samples of Costus afer were collected within the marked plot from a hilly area with a total of 5 points, and a corresponding 5 points for the regular terrain. At each location, soil sample (0-20cm) was collected for physico-chemical properties of the experimental soil. Leaf and soil samples were analysed using standard methods. Results: There were marked variations (P<0.05) in mineral nutrient and proximate contents in leaf samples of Costus afer from the hilly and regular terrain of the study area. The mineral nutrient contents as well as the proximate composition of the regular soil were relatively higher than those of the hilly soil. Conclusions: This study indicates the topographic terrain of the study area has a major influence on the nutrient status and the proximate composition of Costus afer, hence, could play a crucial role in plant growth and development.
Keywords: Topography, soil quality, mineral nutrient, proximate, Yenagoa.
