Abstract :
In order to study the sowing date and the reaction of different cultivars to different planting dates in 2012-2012, three separate experiments were carried out in a randomized complete block design with three replications at Ghamloo Agricultural Research Station. The first experiment was based on autumn sowing date and the cultivation of safflower cultivars was carried out on October 20, 2012. The cultivation of cultivars on December 25, 2012 was carried out as an expected cultivation in the second experiment, and the third experiment was cultured on April 14th. Six cultivars and safflower lines were cultivated in each experiment. By comparing the results of the comparison of the average effect of sowing date and cultivar on grain yield, the highest grain yield in Piddi cultivar was obtained in autumn cultivars. The results also indicate that in cultivation Fall yields more yield than other planting dates (869.7 kg ha-1). The lowest yield was obtained in Sina cultivar under the conditions of spring crop (155.5 kg ha-1). In a general conclusion and considering the dual effects of planting dates and cultivars, and considering the results of this experiment, it can be concluded that autumn cultivation of Faraman cultivars and phenomena under climatic conditions of Kurdistan region can be more favorable than other cultivars.
