Abstract: Environmental factors and cultural practices signifcantly infuence the secondary metabolites in plants, e.g., glucosinolates, depending on the cultivar of each species. The present study analyzed the infuence of specific environmental factors (e.g., temperature, rainfall, and relative humidity), elevation, and fertilization (i.e., nitrogen and sulfur) on the glucosinolate content in leaves of wild-grown Moringa oleifera from three agro-ecological zones in Ghana and selected M. oleifera accessions cultivated under semi-controlled feld conditions. The results showed that climate did not signifcantly infuence total glucosinolate content in leaves of both wild-grown and cultivated accessions of M. oleifera, while elevation signifcantly infuenced the total glucosinolate content of wild-grown plants. Fertilization had no signifcante impact on the total glucosinolate content of the cultivated accessions. Furthermore, wild-collected M. oleifera leaves from the three agro-ecological zones did not reveal a signifcant difference in their total glucosinolate content. For the cultivated accessions of M. oleifera, the agro-ecological zone, harvest time, and accession and the interactions among these factors signifcantly infuenced the total glucosinolate content. The results suggest that selecting suitable accessions, choosing suitable locations, and applying appropriate cultivation practices could contribute to optimizing the production of health-promoting Moringa plants with special emphasis on glucosinolate content.
