The experiment was carried out in the Agricultural Research Farm of the National Taiwan University during the winter of 1997. There were four kinds of treatments in total including a conventional chemical fertilizer control and three rates (30, 60 and 120 Mg ha-1) of compost-treated plots. The cabbage (Brassica oleracea L. Capitata Group, cultivar early spring) was harvested after 94 days of transplanting. After being washed, the plants were divided into the root, the wrapper leaf petioles, the wrapper leaf blades, and the head (the marketable portion). The dry weight and the concentrations of the total nitrogen (N), phosphorus (P), potassium (K), nitrate N (N03-N), ammonium N (NH-N) and insoluble N in various parts of the plants were determined. The results showed that there were no significant differences in the growth of various treatments, However, the productivity of the head of 120 Mg ha-1 compost- and chemical fertilizer-treated plots were higher than those of the 30 Mg ha-1 and 60 Mg ha-1 compost-treated plots. The total N and K concentrations of various parts of the plants were not significantly different for the treatments. However, the P concentrations in the chemical fertilizer-treated plants were lower and those in compost-treated plants increased with increasing the compost rate. The NO-N concentrations in the whole plant, the wrapper leaf blades, and the head of the chemical fertilizer-treated plants were the lowest among all treatments and there were no significant differences in the NO-N concentrations of the head among the compost treated-plots. There were no significant differences in the concentrations of NH4-N, soluble organic N, and insoluble N in various parts of the plants among the treatments. In conclusion, even though with the application of 120 Mg ha-1 of compost, there was no disadvantageous effect on the growth of cabbage, on the other hand, a good yield was obtained.
