Abstract :
To investigate the biological effects of nitrogen and phosphorous fertilizers on crop yield, protein and oil Sunflower Nuts (Use landrace) Cultivated land in the city Sonqor falcon factorial experiment in a completely randomized block design with three replications were evaluated. Treatments, four levels of fertilizer Biological nitrogen include: Nitro Ksyn, Super Nitro Plus, Nitro Kara, and control of biological phosphorus fertilizer levels include: Phosphate2 fertilized, bio zar, Super Plus and control. The results showed that the highest protein content of sunflower Efficient use of nitrogen fertilizer, biological Nitro Kara (%19/95) and phosphor bio zar (%19/76) Obtained. The highest yield of sunflower protein in biological nitrogen fertilizer Nitro Kara (To the 134/74 grams per square meter) and phosphor bio zar (To the 130/13 grams per square meter) And the combined effect biological fertilizers bio zar* Witness (To the 135/53 grams per square meter) Obtained. Most of sunflower oil on biological nitrogen fertilizer Super Nitro Plus (%29/03) and phosphor bio zar (%29/40) The highest percentage of sunflower oil and fertilizer combination Nitro Kara * Phosphate2 (%31/17) ) Obtained. Sunflower oil yield of biological nitrogen fertilizer Nitro Kara (To the 195/93 grams per square meter) and phosphor bio zar (To the 193/18 grams per square meter) And the combined effect biological fertilizers Nitro Kara * Phosphate2 fertilized (To the 213/45 grams per square meter) Obtained.
