Abstract

This experiment was carried out to determine the effects of different plant densities on YIELD and YIELD components of two SUNFLOWER cultivars at Agricultural Research station of Khoy in summer.2005 The experiment was done in Split Plot as a complete block design with four replications. The varieties were chosen as the main polt in 2 levels(Master and CMS26 xR103) and plant DENSITY in 4 levels 71000, 57000, 48000 and (95000 plant per hectare) were chosen as a sub plot. Results showed that Master due to have some good plants traits including, more diameter, grain number, thousand grain weight, oil YIELD, OIL PERCENT and HARVEST INDEX rather than to CMS was better. Average grain YIELD in CMS and Master was 4291, 3991 kg/ha respectively. There was significant difference in 5% level between two cultivars only, grain YIELD and oil YIELD. but the gutted traits were affected by plant DENSITY. DENSITY had significant in 5% level effects the grain YIELD, plant high, and stem diameter and oil content. Also DENSITY had significant effect at 1% level of probability on head diameter and HARVEST INDEX despite to increasing plant DENSITY, the oil content increased but in this experiment, and oil content was shown significant difference at 5% level of probability OIL PERCENT wasn’t significant by cultivar and DENSITY. The whole average of OIL PERCENTage was 41.6 and 43.5 in CMS26 x R103 and Master, respectively. According to results, it’s recommend to planting Master in Khoy situation in DENSITY of 95000 plants per hectare.
