Increase in dairy bovine cattle in Mexico central region, has raise maize forage production demand, however there are not any varieties or hybrids that accomplish both quantity and quality of this feed and also there is no tendency to organic agriculture system. The objective of this research is to generate an organic maize forage production technology. In 2012 four solarized bovine manure (SBM) treatments were evaluated. Factor A was mycorrhiza, with (MA) and (WMA), without application and factor B was SBM with 0, 20, 40, 60 and 80 Me-gagrams (Mg), respectively.  A chemical fertilizer control (CFC) 200-150-00 Nitrogen (N) Phosphorus (P) and potassium (K) Mg ha-1 were also used.  The experimental design in each crop cycle was a complete randomized block with split block arrangement and four replica-tions with a density of 133, 340 plants ha-1 (p ha-1). Forage yields (FY) were evaluated for total green mater (TGM) and total dry matter (TDM) in Megagrams por hectare (Mg ha-1). The variables studied in the soil samples were: electric conductivity (EC), hydrogen potential (pH), organic matter (OM), and nitrates (NO3). Production results showed the highest FY in the 80 Mg ha-1 of SBM with mycorrhiza application. There were no statistical significant differences between factor A levels for TGM and TDM forage yields.
