Abstract EN

A field experiment was conducted in Al-Fayadhiya region / Al-Hashimya township / Babylon government during summer season 2014, use three variety of sesame (Somer, Wadaa, Rafidain) at effect of four planting date (1 May, 15 May, 1 June, 15 June) in order to investigate the best variety can be cultivated in the best planting date under the climatic conditions of middle Iraq in Babylon government and to study the interaction between the varieties and planting dates and its effect in the field traits and the yield and quality.Used experiment of split plot at randomized complete block design (RCBD) with three replication, the main plot contained planting dates, and were cultivated in every planting date, three varieties, the varieties as sub plot that the factor most importance.The data were analyzed statistically by used source of variance and used Less significant difference (LSD) for compare the means of treatments, the studied traits are :number of capsules per plant, capsule length (cm), number of seeds per capsule, weight of 1000 seed (gm), the seeds yield (kg.

ha-1), percentage of oil, percentage of protein.

The variety Rafedain Superiority in most traits of the yield and yield components, its Superiority in the total yield of seeds 1206 kg.ha-1, number of capsules per plant 134.3 capsule.plant-1, the variety Wadaa Superiority in capsule length 3.01 cm which were not significantly different from Rafedain variety 2.90cm.The variety Somer Superiority in the percentage of protein of 7.32% which Superiority on the varieties Wadaa and Rafedain.The planting dates were differed in most traits of the yield and yield components as superiority the planting date 15 May in the yield of seeds of 1141 kg.ha-1 and number of capsules per plant 152.1 capsule.plant-1 .The planting date 15 June superiority in the quality traits its gave the higher percentage of oil of 52.89% , while 1 June superiority in the percentage of protein 7.80% .The variety Rafedain were cultivated in 15 May and 1 June superiority in most of the yield traits, and the total yield of seeds (1268 , 1226) kg.ha-1 respectively.

The variety Wadaa were cultivated in 15 June superiority in the percentage of oil of 53.73%, while the variety Somer were cultivated in 1 June superiority in the percentage protein of 7.80%.
