Abstract

In order to evaluate the effects of PLANT DENSITY on yield, its components and the indices of growth in sunflower cultivar (Ksc43/128 and Lakumka) an experiment was carried out with two row space 60 and 75 cm in agricultural and natural resources research station of Khoy in 2007. The experiment was coordinated as strip plot design with 4 replication: Combination of 2 varieties with row space as horizontal factor and plant densities with 5 levels of 3, 4/5, 6, 7/5 and 9 plant /m2 as vertical factor. Results showed that there was significant difference between horizontal treatments for flowering, growth period, 1000 seeds weight, head seed number and oil percentage. Effect of PLANT DENSITY on plant height, seed and oil yield, head and stem diameter, 1000 seeds weight and seed number per head were significant. As PLANT DENSITY increased to 7/5 p/m2, seed and oil yield increased significantly and when the density reached from 3 to 9 plants per square meter, the weight of 1000 seeds in number and diameter decreased. Russian cultivar Lakumka produced the highest seed yield, 4719 and 4419 kg/ha respectively at PLANT DENSITY 7/5 p/m2 with row space of 60 and 75 cm. Ksc43/128 with 4410 kg/ha seed yield did not have significant difference with Lakumka, but for its highest oil yield, 1989 kg per hectare, stood in first rank.
