Growth and yield responses of sesame (Sesamum indicum L.) to sowing dates and population densities were investigated in Omuo-Ekiti (derived savanna) in 2009 and Akure (rainforest) in 2010. Seeds of sesame were planted at 3 spacing (60 × 30 cm, 60 × 60 cm and 90 × 30 cm) and at 1 and 2 plants per stand on plots measuring 3 × 3 m. Treatments were assigned to field plots using randomized complete block design. Sesame grown in Omuo-Ekiti performed better than in Akure. The effect of spacing was not profound on most of the growth and seed yield characters of sesame. The values of root and shoot biomass, the number and weight of pods and seeds per plant were not significantly different. However, plant height and number of leaves per plant were affected by spacing. Plant population density (number of plants per stand) did not significantly affect root and shoot biomass and number of leaves per plant. Sesame seeds sown at 1 plant per stand produced significantly higher number of pods and seeds compared to 2 plants per stand. Crops grown at 2 plants per stand and with the spacing of 60 × 30 cm performed better than those planted at 60 × 60 cm and 90 × 30 cm. Significant interactions between spacing and number of plants per stand were obtained for shoot biomass, number of leaves per plant, pod yield and harvest index. Contrasting reactions of sesame to plant density were obtained when sesame was cropped at 60 × 30, 60 × 60 and 90 × 30 cm row spacing. The effect of location (site/agro-ecology) was significant on growth and yield. Sesame grown in Omuo-Ekiti (derived savanna) produced higher values of shoot biomass and pod and seed yields. It is concluded that Omuo-Ekiti is better for production of sesame based on the measured parameters in this study.
