ABSTRACT: The field experiment was conducted in the
Department of Botany, University of Ibadan, Nigeria between September to
December 2012. Four accessions of pepper (Capsicum spp.), obtained from Moor plantation in Ibadan and
LUTH (Lagos University Teaching Hospital) vegetable garden, Idi-Araba Lagos
were evaluated to investigate the morpho-agronomic variability and interaction
of accession × treatment × days after transplant in treatment
combinations of arbuscular mycorrhizal fungus (Glomus clarum) and
cowdung. The experiment was a 4 × 4 factorial arrangement laid out in a
randomized complete block design with three replications. The combined analysis
of variance showed significant accession, treatment, days after transplant, and
accession × treatment interactive effect for most of the
growth characters at P 0.01 and P 0.05. The result also showed significant difference in yield related
traits of fruits for pepper accessions. The number of leaves per plant was significant and positively associated with
plant height (r = 0.516; P 0.05), and highly significant and positively
correlated with the number of branches (r = 0.836; P 0.01), but negative and non-significantly
related with stem girth. Glomus clarum treated plants responded
significantly with higher growth and yield. It suggested that G. clarum treatment had higher potential in influencing crop yield
compared to cowdung and untreated plants. This study further explored the relationship between G.
