Abstract

In order to evaluate the best SOWING DATE and its effect on yield and YIELD COMPONENTS of SUNFLOWER cultivars, a field experiment was done as split block design in a randomized pattern of complete block design with three replications in 2009 in Shahinshahr, Isfahan. The SOWING DATE was studied in four intervals: 22 June, 2009, 1 Jul, 2009, 11 Jul, 2009, and 21 Jul 2009. The four factors used were, Alestar, Azargol, Master and Zaria. The results showed that SOWING DATE had a significant effect on the number of seed, weight of thousand seeds, SEED YIELD, LAI, Cap diameter and oil percentage. The higher SEED YIELD (4170 kg/ha) was obtained from the first SOWING DATE (22 June.2009), and the lowest SEED YIELD (2230 kg/ha) was obtained from the last SOWING DATE (21 Jul.2009). The average of SEED YIELD in 1 Jul.2009 and 11 Jul.2009 was 3980 and 2760 kg/ha. The highest number of seed (759.5) and weight of thousand seeds (55 gr) was obtained from 22.June.2009 and the lowest number of seed (619.3) and weight of thousand seeds (36 gr) was obtained from 21.Jul.2009. The CULTIVER had a significant effect on all studied traits except the number of seeds. The highest and lowest SEED YIELD were related to Azargol (4090 kg/ha) and Alestar (2450 kg/ha). The SEED YIELD of Zaria and Master were 3500 and 2910 kg/ha. The highest and lowest weight of thousand seeds was obtained from Azargol (57 gr) and Alestar (38 gr).
