Abstract :

      To study the effects of plant density and yield components of sunflower cultivars, an experiment was conducted in the city of Bam Rudab. The experiments using split plots in a randomized complete block design with three replications was conducted where the density at three levels (30 = D3 and 20 = D2 or 10 = D1) as the main factor and Figures V1, V2, V3, V4, were examined as secondary factors. The results show that the compression performance of different varieties and plant height, seed weight, number of seeds per head, head diameter, yield per plant, yield per unit area, number of leaves per plant and leg diameter there is a significant difference so that the maximum performance of the D1 density of 709/3 and the variety V1 (Azargol) of 843/3 per acre and the lowest density of D3 443/3 and the number V4 (Mehr) of 162 / 3 tons per hectare allocated and the total density and cultivar effects on yield and some yield components were summed so that there is a significant difference between the characteristics and performance of the combined treatment, D2 V1 and D1 V2 are the majority with no statistical differences and the lowest yield of the treatment combination of D3 V4 04/3 tons per hectare is devoted to the treatment combination of a statistical analysis are D3V4.
