To evaluate the efficiency of organic fertilizers on the agronomic characteristics, yield and yield components of maize cultivars SC (704) and (260 ) a experiment was carried out. Agricultural Research Center of Khorasan through the research field station in 2012. The effects of 9 fertilizer treatments included three types of organic fertilizers (16 and 32 tons per hectare), cows (24 and 48 tons per hectare), poultry (9.5 and 19 tons per hectare), fertilizers of 225 and 450 kg of urea Hectar and no fertilizer use (control) as main plots and two varieties of corn (Formerly Single Crossfader and Late 704) in sub plots were split plot based on randomized complete block design with three replications were studied. The results of analysis of variance of the test data showed a significant difference between the treatments in ear diameter, ear length, ear height and length of Tassel at 5% level, and for the time interval between the emergence of pollen and silk fibers (ASI), (days from planting to pollination) (Tassal emergence) and total leaf area at 1% level. The results of mean comparison with Duncan's multiple range showed that the maximum forage yield (biomass and dry biomass) belonging to the compost treatment was 32 tons per hectare with average yield of 70.41 and 52.84 tons per hectare and the lowest forage yield (biomass and Dry biomass) belonged to control treatments 49.16 and 39.15 tons per hectare, respectively.
