Note: For each green manure type, means within a column followed by the same letter (a,b,c and d) are not significantly different (P<0.05). PGM & FGM₀: control without green manure; PGM & FGM₅₀, PGM & FGM₁₀₀, and PGM & FGM₁₅₀: pod shells of pea (P) or faba bean (F) added as GM at rates of 50, 100, and 150 kg N ha^-1, respectively.
