Phosphorus (P) is an essential element for plants, deficiency and excess of P in soil will limit plant growth. It is required to
applicate P fertilizer in appropriate dosage for promoting plant growth on the soil with different properties. The purpose of
experiment was to study the respon of maize (Zea mays L.) for phosphorus fertilization on Regosol and Latosol soils. A glass
house experiment was conducted to study maize response on P fertilizer application in Regosol and Latosol soils. The treatment
was 0, 112, 336, 1008, 3024 and 9072 kg superfosfat ha1
. P fertilizer tend to increase the biomass of maize but exceed of P
fertilizer reduced maize biomass. The optimum fertilization and availability of P for plant affected by soil properties.
