The agricultural lands of Sinaloa have been intensively cultivated for over 50 years with increasing use of chemical fertilizers and decreasing use of organic applications. This situation has led to an environmental problem which is gradually getting worse; this is this study chooses to focus on the study of the application of organic additives such as vermicompost and supermagro in the cultivation of criollo corn. The treatments studied were: T1= criollo corn organic fertilizers with mineral fertilization; T2= criollo corn with organic fertilizers and without mineral fertilization; T3= criollo corn without organic fertilizers and with mineral fertilization; T4= criollo corn without fertilization; T5= hybrid corn with mineral fertilization of N, P and K and T6= hybrid corn without fertilization. 3 t.ha- 1 of vermicompost in pre-seeding stage, 250 L.ha-1 of supermagro and mineral fertilization (350 N, 120 P, 0 K); the experimental design implemented randomized complete blocks, with four repetitions. The response variables were: CO2 release from soil, vermicompost decomposition rate in soil and corn grain yield. The accumulation of biomass in corn development stages was benefited by the stimulation of the CO2 concentration after obtaining an acceptable grain yield, with the application of vermicompost as an organic fertilizer, concluding that the application of organic additives of vermicompost and supermagro showed that criollo corn grain yield of Sinaloa is practicable in accordance with the experiment results.
