Abstract

This test was performed to study the effects of NITROGEN, POTASSIUM and plant DENSITY on YIELD and YIELD components of Confeta Hybrid SUNFLOWER in a field in Var road of Khoy. It was done as a 2 factorial test in complete random block. Confeta Hybrid were compared in 3plant DENSITY of 4.5, 5.5, 6.5 in square meter and NITROGEN and POTASSIUM manure with the rate of 75, 100 and 125 percent regarding their YIELD and plant YIELD components and some qualititative and quantitative characteristics. Results show that the effect of plant DENSITY on petals diameter, weight of 100 seeds, p height, stem diameter, oil percent, biologic YIELD, seed YIELD and harvest index was significant.Effect of fertilizer on seed height was significant, too. Results show that increasing fertilizer consumption from 75 to 125 percent, increases seed performance from 353.69 gram to 500.67 gr/m2 Biologic YIELD increased from 1172.62 up to 1364.84 gr/m2.Seed YIELD increased from 399.29 up to 460.13 by increasing plant DENSITY from 4.5 to 5.5. According to one year results of this study, 5.5 plant densities in each square meter is recommended for Confeta hybrid SUNFLOWER as well as NITROGEN and POTASSIUM consumption up to 125 percent.
