The aim of the this study was to examine the effect of planting date (May 31, June 15 and June 30) and organic fertilizers [compost (100%), manure (100%) and compost 50% + manure 50%] on the agronomic traits of sesame varieties (Tak Shakhe Naz, Kerman (MD) and Gorgan cultivars) in Kordkouy in the crop year 2012-2013. Split plot factorial experiments were performed with three replications in a randomized complete block design. The planting date was considered as the main plot. The sesame varieties and fertilizers were considered as subplots. The results indicated that the delay in planting reduced plant height (4%), dry matter yield (8.9%) and harvest index (3.1%). However, it increased seed oil content (5%) by reducing the plant density. Although the use of compost improves the agronomic traits, it will reduce the seed oil content (3.1%) due to increased plant density. The differences observed between varieties for different traits were significant at the significance level of 1%. The Kerman, Tak Shakhe Naz and Gorgan cultivars showed the best performance in terms of plant height (125 cm), dry matter yield (4579 kg/ha) and harvest index (25.2%) and seed oil (55.6%), respectively. According to the results of this experiment, the use of manure and planting in late June are recommended to achieve the highest seed oil content.
