Peran Pemupukan Posfor Dalam Pertumbuhan Tanaman Jagung (Zea Mays L.) Di Tanah Regosol Dan Latosol [the Role of Phosphorus Fertilization on the Growth of Maize (Zea Mays L.) in Regosol and Latosol Soils]

Phosphorus (P) is an essential element for plants, deficiency and excess of P in soil will limit plant growth. It is required toapplicate P fertilizer in appropriate dosage for promoting plant growth on the soil with different properties. The purpose ofexperiment was to study the respon of maize (Zea mays L.) for phosphorus fertilization on Regosol and Latosol soils. A glasshouse experiment was conducted to study maize response on P fertilizer application in Regosol and Latosol soils. The treatment1was 0, 112, 336, 1008, 3024 and 9072 kg superfosfat ha . P fertilizer tend to increase the biomass of maize but exceed of Pfertilizer reduced maize biomass. The optimum fertilization and availability of P for plant affected by soil properties
