The spent mushroom substrate is a growing media obtained from the mushroom substrates that are no longer productive. Spent mushroom substrate contains 49% organic matter and has advantages in the physical properties of the growing media, such as good water storage for forage nursery planting media. Fodder is a system used to manufacture animal feed in a shorter time. One of the plants commonly used as fodder is maize. Maize fodder is a forage with high nutrients for animal feed. To produce nutritious maize fodder, a growing media should have high available nutrients; spent mushroom substrate is one source of growing media that can be combined and provides nutrients and is an ideal growing media for plants. This study used a completely randomized design consisting of 10 treatments with three replications, namely treatment A (soil and cow manure with hybrid seed), B (spent mushroom substrate and cocopeat with hybrid seed), C (spent mushroom substrate and raw husk with hybrid seeds), D (spent mushroom substrate and burnt husk with hybrid seed), E (spent mushroom substrate and cow manure hybrid seed), F (soil and cow manure with non-hybrid seed), G (spent mushroom substrate and cocopeat with non-hybrid seed), H (spent mushroom substrate and raw husks with non-hybrid seed), I (spent mushroom substrate and burnt husks with non-hybrid seed), J (spent mushroom substrate and cow manure with non-hybrid seed). Based on the study's results, it is known that the combination of spent mushroom substrate growing media with cow manure resulted in relatively better biomass and nutritional values than other treatments. The plant height produced in this planting medium was 27.18 for hybrid varieties and 29 for non-hybrid varieties. The value of wet weight treatment of spent mushroom substrate and manure was 306.30 in hybrid varieties and 296.30 in non-hybrid varieties. Crude fat, crude protein, and crude fiber content in hybrid varieties respectively are 4.15; 9.50; and 14.70; while the non-hybrid variety was 4.64; 16.44; and 14.97
