Abstract
Chinese cabbage (Brassica campestris Linnaeus ssp. chinensis (L.) Makino) was planted under 57% shade at a spacing of 20 cm × 25 cm, 60 plants each plot covering 3 square meters, and treated with 4 levels of nitrogen. A randomized block design was arranged with 3 replications. The results showed that the treatment with 150 kg/ha of nitrogen produced the highest yield of Chinese cabbage which contained rather lower nitrate but obviously higher Vitamin C, soluble protein and soluble sugar than other treatments. This treatment (150 kg/ha) is considered optimum for shelter cultivation of Chinese cabbage.
