Nitrogen (N) and Phosphorus (P) are essential nutrients for plant. The deficiency one of these nutrients will be limiting the plant
growth. A glass house experiment with one treatment factor was conducted to study the effect and interaction of N and P fertilizers
application on maize growth in regosol and latosol soils. The results show that the interaction of N and P fertilizers application
(N 1 P 1) on regosol had a significant influence to plant height on 3 to 7 weeks after planting, whilst on latosol had a significant
influence to plant height on 1 to 5 weeks after planting. The shoot dry weight, root dry weight and total dry weight of maize on
regosols and latosol soils were significantly influenced by the interaction of N and P fertilizers application (N 1 P 1). There were
a positive correlation between N and P fertilizers application on both soils types to the total plant dry weight.
