Abstract :

The adverse effects of unfavorable environmental factors are important in warm and dry regions due to limited water resources and evaporation. This study was carried out to determine agronomic traits and oil yield of safflower (Carthamus tinctorius L.) cultivars planting methods at Kashan in 2014. The experiment was conducted as factorial arrangemed in a randomized complete block design with three replications. Treatments were planting methods (flooding, furrow bed method, high water mark, planting on rows) and safflower cultivars (Goldasht, Esfahan local, Soffeh). Each plot consisted of 4 rows, 5 m long with 50 cm between rows space and 5 cm between plants on the rows. Plant height, stem diameter, number of branch, number of unfilled capsuls, number of capsuls per m-2, number of seed per m-2, weight of seeds, biological yield, harvest index of plant and oil yield were measured. Results showed that the interaction between safflower cultivars and planting methods on plant height, number of capsuls per m-2, number of seed per m-2, weight of capsuls grains, biological yield of plant, harvest index and oil yield was significant. The highest and lowest oil yield (389.7 and 254.3 kg ha-1) were obtained with Goldasht cultivar in high water mark and Esfahan local cultivar in planting on furrow. Therefore, safflower planting at high water mark method can reduces the accumulation of salts from the evaporation surface in areas with hot and dry weather, such as kashan
