Determining of planting arrangement in spring genotypes of safflower

Effects of the planting arrangement on the yield, its components. seed oil percentage and certain agricultural properties of safflower (Carthamus tinctorius L.) were studied in Gogan (located in east Azarbayjan) during 8-8. The space between rows were 5, 0, 60 centimeters and the distances between the plants were 5, 0, 5 centimeters and Genotypes involved IL, Kj88 and Arak-8. The experiment was done based on factorial based randomized block design in replications. During the experiment; different properties were studied including plant height, numbers of branchs of a plant, number of bolls, number of seeds in a boll, seed yield, harvest index, thousand seed weight and seed oil percent. Analysis of variance showed significant differences among genotypes in number of the seeds in capitulum, number of capitula in a plant, thousand seed weight, plant height and seed yield. At the same time, planting arrangement had significat effect on number of capitulum in a plant, number of seed in a capitulum and seed yield. The 5 cm resulted in the highest yield. It can be said that the Arak-8 with 4.4 tons seed yield/ha was the best. It seems that, development of safflower is of great value specially in medium and poor soils of Ourmieh Lake edges (e.g. Gogan) to obtain an acceptable production
