The agronomic characterization is an important factor, in which it allows the selection of cultivars that are better adapted at the place of cultivation. The objective of this work was to characterize corn cobs of the Creole varieties: Roxa corn; corn straw; and the cultivar AG1051, regarding the physical and chemical parameters, as well as to evaluate the mass yield of each variety aiming its application in food processing. The creole varieties were planted at Fazenda Vera Cruz, in the municipality of Morrinhos - GO (17 ° 37 '58.96 "S and 49 ° 09' 55.99"), in three plots, each containing a variety (purple, green and gusty straw). Harvesting of the spikes was considering the milky grain, with 70% to 80% of humidity. The ears of cultivar AG1051 were purchased at a fair in the city of Morrinhos - GO, adopting the same requirements. Ten ears of each Creole variety and ten ears of cultivar AG1051 were randomly selected and the length and diameter of the selected samples were measured using a digital caliper and weighed in a semi-analytical scale. Then the process was repeated with the debris spikes. The mass was extracted, where it was weighed and separated from the bagasse. The samples were chemically evaluated for potentiometric pH, titratable acidity, humidity (greenhouse at 105ºC) and ashes (muffle at 550ºC). It was concluded that the creole varieties had values similar to those of cultivar AG1051. considered a viable alternative to substitute hybrids for processing, thus reducing the cost to small producers.
