The effects of some soil media viz., sand, clay, loam + sawdust (in a 1:1 ratio), and “Garden“ soil on the seed germination of 9 cultivars of the Helianthus annuus L. was investigated in a laboratory study. The results obtained showed that higher germination percentages of above 60% in most of the cultivars were observed in the sandy and loam + sawdust media. A consequent performance was also recorded for the garden soil treatment. However, low germination percentage of below 40% was observed in the clay treatments.
