Abstract

In order to study the effects of Planting date on yield, yield components and oil content of safflower (Carthamus tinctorius L. ), a field experiment was conducted in Research Station of Islamic Azad University– Branch of Birjand, in 2011. Experimental design was Randomized Complete Block that arranged as split plot. Planting date (17 Oct, 1 Nov, 16 Nov & 1 Dec) and cultivars (LRV, Zarghan & Isfahan) were arranged as main plots and sub plots, respectively. The results showed that number of head per plant, number of grain per head, biological yield, grain yield and oil yield were significantly affected by Planting date. Every 15 days of delay from the first Planting date (17 October) reduced the grain yield by 33. 3, 48. 3 and 56. 5%, respectively. But, 1000-grain weight, Harvest index and oil content were not affected by Planting date. The first Planting date (17 Oct) was the best for all traits. Number of grain per head, grain yield and Harvest index were significantly affected by cultivars. LRV cultivar was the best for this traits. Number of head per plant, 1000-grain weight, biological yield, oil content and oil yield were not significantly affected by cultivars. All of traits were significantly affected by interaction of Planting dates and cultivars, exception oil content. On the base of these results, the first Planting date (17 Oct) and LRV cultivar were the best for Birjand region (East of Iran).
