The high production Manado Kuning corn obtained from treatment P4 (Inorganic fertilizers  75 Kg / Ha NPK and 75 Kg / Ha Urea + 12,5 Ton / Ha Compost) caused by availability adequate nutrient to support production. Deficient inorganic fertilizers can overcome by organic fertilizers, so organic fertilizers and inorganic fertlizers very good for in aply simultaneously. For increasing production Manado Kuning corn suggested to use fertilizing dosage 75 Kg / Ha NPK and 75 Kg / Ha Urea + 12,5 Ton / Ha Compost
