Abstract :

This study was conducted for evaluating the effects of nitroxin biologic fertilizer on yield of safflower in the presence of chelate EDTA. The factorial experiment was performed in Islamic Azad University's research farm in randomized complete design whit three eplications. The examination factors included: the consumption of biological nitroxin in 3 levels (0, the consumption of 1 L/ha as seed treatment and the consumption of 4L/ha as leaf spraying) and 2: the consumption of chelate EDTA in 3 levels (0, 20, 40 g/m2). The result showed an increase in the grain yield, plant dry weight, plant height, concentration and content of nitrogen compared to the control. Nitroxin did not showed to have a significant effect on the number of branches in plant and the number of bolls in plant. Chelate EDTA also showed a significant effect on the grain yield, the plant dry weight and the number of bolls in plant but no significant effect on other studied characteristics. The best performance was achieved in the treatment of The second level of Nitroxin and the third level of EDTA.
