The effect of planting date on yield and yield components of different sesame cultivars under Miyaneh climatic condition.

This study was conducted to investigate the effect of two planting date on yield and yield components of four sesame cultivars including Mahalli Varamin, Moghan-7, Karaj– and Mahalli Behbahan at resarch farm of Islamic Azad university, Miyaneh branch during summer 005. Experiment was conducted as factorial based on randomized complete block design with replications. In this study, dry weight of various organs, capsule numbers of each plant, number of seeds in a capsule, protein and oil percentage, and yield was evaluated. Results revealed significant difference between planting dates in most of evaluated traits, except grain yield. There was significant difference between planted cultivars in most evaluated traits, except number of capsules, protein percentage, dry weight and grain yield. The difference of the interaction between planting date and cultivars on studied traits such as number of seeds in a capsule, weight of 000 seeds and harvest index (HI) were also significant. The results showed that karaj- and Mahally behbahan cultivars had maximum (65 kg/ha) and minimum (745kg/ha) yield, respectively.
