Abstract

To understand the effect of different planting dates on some agronomic and phenologic traits related to sunflower cultivars, the experimental study was doing with Split Plot based on Completely Randomized Block Design with four replicate, a trial was in Agricultural Research Station of Khoy in 2009. Planting dates factor were allotted to main plats in 4 levels (as of 20th May 2009 with sowing distance of 20 days till 9th July 2009 and cultivars factor were only 3 ones (Alstar, Euroflor and KSC43.128) and randomly allotted to subplots. Results indicated that, planting date had considerable effect on agronomic as well as phenologic traits of sunflower. In third planting date, the highest total seed number per head, thousand seed weight, seed yield, oil yield and HARVEST INDEX were achieved. All studied traits were also highly affected by cultivar treatment. Among tested cultivars ‘KSC43.128’ with the mean growth period of 111 days and ‘Alstar’ with the mean of 117 days were the earliest and the latest season’s cultivars, respectively. ‘Alstar’ showed the highest plant height, thousand seed weight, seed yield and oil yield. The highest total number of seeds per head was that of cv. Euroflor. In this study, ‘KSC43.128’ had the highest HARVEST INDEX. In terms of importance of seed oil yield in oily sunflower, the results of this research emphasizing that in agro-climatic condition of Khoy, planting date of D3 (2009) along with ‘Alstar’ in second planting date toward gaining the much desirable seed/oil yield could be suitable.
