Abstract :

In order to study the effects of Azosprilium and Cytokinins Hormone on the physiological traits of corn ( Zea Mays L. ), an experiment was conducted in Agriculture Research Farm of Miandoab during the farming season of 2014. Experimental factors were Azospirilium in three levels ( control, 8 and 25g ) and cytokinins hormone in three levels ( control, 100 milligrams per liter, 200 mg/liter ). Factorial design was a randomized complete block with three replications. Results showed that the use of Azosprilium had significant effect on leaf weight, cob weight, seed number per row, biological yield, grain yield, grain phosphor and oil. Except for cob weight, cytokinin had significant impact on all understudied traits. Interaction of azosprilium and cytokinin had also considerable effect on leaf weight, cob weight grain number per row, 1000-kernel weight, biological and grain yield and chlorophyll content. The comparison of azosprilium level mean showed that level of 25 grams produced highest amount of cob weight, grain number per row, biological yield, grain yield, and chlorophyll content. Cytokinins treatment level of 100 mg/liter brought about the highest amount of leaf weight, cob diameters, grain yield, and chlorophyll content. Furthermore, interaction between azosprilium and cytokinins treatment 25 grams azosprilium combined with 100 mg/liter showed the highest leaf weight, cob weight, grain number per row , grain yield, and chlorophyll content. Therefore, the use of these compounds can reduce the amount of chemical fertilizer and economic pressure on farmers and also can diminish the environmental pollution.
