초록

This study was conducted to assess the yield and nitrate content of Chinese cabbage (Brassica campestris ssp. pekinensis Rupr) grown in the field with four different levels of commercial compost; 0 (control), 37.5, 75.0, and 150 tㆍ㏊?¹ commercial compost. There was a tendency for the total yield to be highest when fertilized with compost and lowest when the compost was not supplied. The plants with the highest compost treatment (150.0 tㆍ㏊?¹) gave significantly highest yield at 46.87 tㆍ㏊?¹ which was statistically different from other treatments with the lower compost. The significant differences were also found on marketable yield with an exception at the lowest compost treatment. The highest head weight at 520.8 g was obtained in 150.0 tㆍ㏊?¹ compost treatment, which was statistically significant from other treatments with lower compost. The lowest nitrate content in the leaf was observed in 150 tㆍ㏊?¹ compost treatment followed by 37.5 and 75.0 tㆍ㏊?¹ compost treatments with 2,161 and 2,608 ㎎ㆍ㎏?¹, respectively. Nitrate contents in the petiole were shown the same results with those in the leaf. However, significant differences in nitrate contents were not found among the treatments.
