BACKGROUND: To evaluate the application level ofexpeller cake fertilizer(ECF), we have investigated soilchemical properties, leaf mineral contents and yield of tahtasai Chinese cabbage in a plastic film greenhouse. METHODS AND RESULTS: Five levels of fertilizer wereapplied as 0%(ECF 0), 50%(ECF 50), 75%(ECF 75), 100%(ECF 100) and 150%(ECF 150) by base 1,848 kg/ha ofECF. In 2012, tah tasai Chinese cabbage was planted onApril 28 in a silt loam soil and harvested on July 12. Commercial yields were measured 10 times from May 10 toJuly 12. Electrical conductivity (2.24∼3.09 dS/m), availableP2O5(484∼581 mg/kg) and exchangeable cations(K+, Ca2+and Mg2+) were tended to increase by the application ofECF. However, the range of those was not significant. Thecontents of T-N, K, Ca and P of tah tasai Chinese cabbageleaves were 62.2∼66.5 g/kg, 44.3∼48.7 g/kg, 5.1∼5.9 g/kgand 5.6∼6.2 g/kg, respectively. The nitrogen utilizationrate of tah tasai Chinese cabbage was 39.4∼51.6%, and itwas decreased with increased application amount of ECF. The yield of tah tasai Chinese cabbage was 9,806 to 12,730kg/ha on the basis of application amount of ECF and it wasnot increased in spite of increased ECF. CONCLUSION: The optimum dose of application of ECFfor cultivation of tah tasai Chinese cabbage was rangedfrom 924 kg/ha(as ECF 50) to 1,386 kg/ha(as ECF 75). Environment-friendly and economical amount of appliedfertilizer is more important than yield for cultivation of tahtasai Chinese cabbage.
