  In order to study the corn response to the application of various chemical, nano, nano-biological fertilizers and organic extract of seaweed, an experiment was carried out at the research farm of agriculture faculty-Islamic Azad university- Sanandaj branch during 2016-2017. The experiment was conducted as split plot in a completely randomized block design with three replications. The main factor included the application of different fertilizers in six levels (control, chemical fertilizer, nano fertilizer, nano-biological fertilizer, combination of 50% chemical fertilizer + nano fertilizer, combination of 50% chemical fertilizer + nano-biological fertilizer) and a sub-factor including application of seaweed extract in two levels (control: distilled water and application of seaweed extract) were considered. The results showed that the effect of fertilization was significant on the characters as: cob length, cob diameter, number of rows per cob, number of seeds per row, 1000 grain weight, grain and biological yield, protein and oil percentage. The highest grain and biological yield were obtained from a combination of 50% chemical fertilizer + nano-fertilizer, which increased 10.52% and 14.85%, respectively in comparison with chemical fertilizer. The effect of seaweed extract on all studied traits was significant, with except to number of cob per plant. The seaweed extract increased the grain and biological yield to 12.48 and 11.66%, respectively. The results of interaction effects on all traits were significant with except to cob number and protein percentage. Finally, the maximum grain and biological yield were obtained from the combination of 50% chemical fertilizer + nano-fertilizer and seaweed. Manuscript profile
