An experiment on corn varieties to the combined application of organic and inorganic fertilizers was conducted. The study was laid out in a split plot arranged in RCBD with three corn varieties as the main plot while six fertilization strategies as subplot treatment such as follows; S₁ - No fertilizer application; S₂ - 90-60-60 kg ha^-1 N, P₂O₅, K₂O; S₃ – 5 t ha^-1 V₄ Organic Fertilizer; S₄ - 3.75 t ha^-1 V₄ Organic Fertilizer + 22.5-15-15 kg ha^-1 N, P₂O₅, K₂O; S₅ - 2.50 t ha^-1 V₄ Organic Fertilizer + 45-30-30 kg ha^-1 N, P₂O₅, K₂O and S₆ - 1.25 t ha^-1 V₄ Organic Fertilizer + 67.5-45-45 kg ha^-1 N, P₂O₅, K₂O. The hybrid corn variety “Macho F₁" developed longer, bigger, and heavier ear weights; produced the highest marketable ear and total ear yield (t ha^-1), and achieve a higher gross margin of USD 2,782.15. The application of 1.25 t ha^-1 V₄ organic fertilizer + 67.5-45-45 kg ha^-1 N, P₂O₅, K₂O (S₆) and 2.50 t ha^-1 V₄ organic fertilizer + 45-30-30 kg ha^-1 N, P₂O₅, K₂O (S₅) enhanced remarkably the agronomic characteristics, and the yield and yield component parameters especially the weight of marketable ears (t ha^-1) that result to achieve higher gross margins. The combined application of fertilizers is recommended to corn growers not only in helping their financial production constraints but this will support an adaptation strategy in reducing the ill effect of climate change in their corn production undertaking in the tropics
