Performance of Sesame (Sesamum indicum, L.) in Southwestern Nigeria as Influenced by Rowspacing

Experiments were conducted in two ecological zones in Nigeria during 1977 and 1978 to investigate the influence of inter-row spacing on growth, development and yield of sesame (Sesame indicum, L.). 16 treatments, consisting of two cultivars (Yandev 55 and 65A - 36) and eight rowwidths (7.5, 15.0, 22.5, 30.0, 37.5, 45.0, 52.5 and 60.0cm) were tested in a randomised complete block design with four replications. Leaf area, dry matter production and yields were significantly influenced by inter-row spacing. Dry matter accumulation increased with increase in inter-row spacing. Seed and oil yields increased with inter-row spacing up to 37.5cm Greater dry matter was diverted into the capsule of plants grown in 37.5cm rows. Cultivar 65A - 36 was significantly better with a mean yield of 428 kg/ha than Yandev 55 which gave 360 kg/ha. Seed production efficiency was higher by 8% in cultivar 65A - 36 than in Yandev 55. The growth analysis suggested that the green capsules contributed towards the accumulation of their dry matter.
