Abstract: To study the effects of reconciliation usage of some of nitrogen stabilizers (Azetobacter, Azospirilium and Azorhizobioum), chemical fertilizer of urea, Zn (Zinc) and Fe (Iron)-EDDHA on the operation and operation components of rice, a split-factorial test in the framework of complete random block design was conducted with 3 replication in Bandar-Anzali (North of Iran) in 2011 crop year. In this test, nitrogen fertilizer as the main factor was in 3 levels (control, biologic fertilizers (reconciling Azetobacter, Azospirilium and Azorhizobioum bacteria) and chemical fertilizer of nitrogen (150 kg ha-1 urea)) and two subsidiary factors were fertilizers of Zn and Fe-EDDHA in two levels (control and using 5 in 1000 EDTA EDDHA in the form of leaf). Results showed that the effect of nitrogen fertilizer on stalk length, number of grain per cluster and the content of grain was meaningful in 1%. Reciprocal effects of nitrogen and Zn on the number of tillers in square meter and reciprocal effect of nitrogen, Zn and Fe on the length of cluster was meaningful in 5%. The highest mean of stalk (113 cm), number of grain per cluster (89.4) and the content of grain (54.2 kg ha-1) was achieved by using urea fertilizer.
