  1. Mean values with different letters along the column differ statistically at P < 0.05. Data represent the mean (n = 3). The standard deviation of the means is shown in parentheses. T1: 500 g soil + 5000 kg ha−1 compost. T2: 500 g soil + 5000 kg ha−1 compost + 100 kg N ha−1. T3: 500 g soil + 5000 kg ha−1 compost + 200 kg N ha−1. T4: 500 g soil + 5000 kg ha−1 compost + 400 kg N ha−1
