Solenostemon rotundifoluis (Poir) J.K.Morton is among the minor and underutilized tuber crops species in Africa which is experiencing a gradual genetic erosion. There is little information on the agronomic practice, production, utilization and processing of the crop. The need to intensify research on the cultivation of the crop in Nigeria in terms of growth and performance has become imperative. In this experiment, some selected accessions of Solenostemon rotundifoluis were grown in Jos-Plateau state, Nigeria, and evaluation of the crop for its yield and growth performance was carried out. The experiment was laid out in completely randomized design (CRD) with three replicates. Results obtained showed significant differences amongst the accessions. The leaf area index increased with time up to 135 days after planting (135 DAP) and thereafter decreased in all the accessions. Relative growth rate and net assimilation rate also increased with the crop age up to 90 days after planting, and thereafter decreased in all the accessions. Also, the harvest index increased with time up to 180 days after planting. The yield for fresh harvested tubers was low in all the accessions of Solenostemon rotundifoluis used in this study. This experiment shows that further study should be carried out for yield improvement in the Solenostemon rotundifoluis.
