Fig. 1. Comparison of rice grain yield according to replacement ratio of mixed organic fertilizer(n=1), mixed oil cake(n=1), and organic compound(n=1) based on basal amount of inorganic(nitrogen) fertilizer in two soils with different organic matter content. ( ) mean relative grain yield of other treatments to NPK treatment. †Numbers with same letter are not significantly different(Duncan’s multiple test, p < 0.05).
