Effect of Sowing Date and Different Planting Management, on Seed Yield and Yield Components of Safflower in Isfahan Region

ABSTRACT: In order to evaluation of sowing date and different planting management, on seed yield and yield components of safflower, an experiment was conducted in 2010-2011 in a research farm of farming building of Islamic Azad University Khorasgan (Isfahan) Branch located in Khatun abad village (latitude 32o /40ʹ N and Longitude 51o /48ʹ E). A split split plot layout within randomized complete block design with 3 replications was used. Main plot were sowing date (Including: 18 Mar, 5 Apr and 27 Apr), and sub plots were seed mass (with 3 different planting management), and groups emerged were as split split plots. Condition represented the effects of sowing date, seed mass and groups emerged were significant on all measured factors. First planting date (18 Mar), Second seed mass and first groups emerged resulted the maximum level of all mentioned factors. On the basis of the results obtained, 18 Mar might be suitable for safflower sowing date in Isfahan region, under the condition similar to the present study.
