Abstract

A study was conducted to evaluate the effects of organic, inorganic and integrated FERTILIZER SYSTEMs on the YIELD and AGRONOMIC N-EFFICIENCY traits of different SUNFLOWER cultivars in 1977 and 1998 at the Miandoab Research Station; the experiment was based on a split plot design with RCBD arrangement in 3 replications. The main plot was composed of various levels of chemical fertilizers (40, 80, 120, 160 and 200 kg N/ha), organic fertilizers (6, 12, 18,24,30) t/ha farm yard manure(F.Y.M.), integrated fertilizers (40 kgN+24 t F.Y.M., 80 kg N+18 t F.Y.M, 120 kg N+12 t F.Y.M. and 160 kg N+6 t F.Y.M/ha), and control (no fertilizer), subplot was composed of 4 SUNFLOWER cultivars, (AS-508, Hysun-33, Armavirski and Record). Results showed that in both years of experiment, the integrated FERTILIZER SYSTEM treatments and 200kg N/ha treatment showed a significant higher seed and nitrogen YIELD than the other treatments and control. The inorganic fertilizer treatments showed the highest increment in nitrogen content. Among organic fertilizer treatments, the 30 t F.Y.M treatment had the highest N content. The integrated fertilizer treatments 120 kg N+12 t F.Y.M M/ha had the highest nitrogen contents, than the other treatments of this system. The inorganic FERTILIZER SYSTEM treatments had the highest AGRONOMIC N-EFFICIENCY (A.N.E.). In both yearly experiments the highest A.N.E was related to treatment of 40 kg N. The organic fertilizer treatments had the least A.N.E and among the integrated fertilizer of system treatments the A.N.E was the highest in the treatment 160 kg N+6 t F.Y.M. Based on the results, application of mixed inorganic and organic, fertilizers would not only reduce the chemical fertilizer consumption per unit area but also would increase the YIELD which would lead to achieve sustainable agriculture. Among the cultivars studied, Hysun-33 and AS-508, had the highest seed and nitrogen YIELD. Results showed that Hysun-33 and AS-508 cultivars are suitable and could be recommended for this region.
