Effect of Balanced Fertilization on Cape Jasmine Yield and Quality in Jiangxi, 2007
Cape jasmine is one example of a famous, traditional Chinese medicinal herb and cash crop grown in Jiangxi Province. The current cultivated area is 11,000 ha, which represents 75% of the total Cape jasmine production in China. Poor nutrient management is one of the main issues that is limiting yield and quality of the crop. The Soil and Fertilizer Institute of Jiangxi Academy of Agricultural Sciences established this research project in 2004 to study balance fertilization (BF) technology for Cape jasmine. Soil analysis determined that micronutrients such as boron (B) and zinc (Zn) were seriously deficient in Cape jasmine soils. Field experiments in 2004 did not find differences in yields with treatments varying P and K application rates. However, differences between these treatments became apparent in the second year of study, and they have increased steadily year-by-year.
In 2007, the highest yield of 8,685 kg/ha was produced with 300-90-360 kg/ha, while deletion of K produced a yield of 4,705 kg/ha. The most economic treatment of 300-180-120 kg/ha returned a net income of US$1,384/ha. The ratio of N:P:K in the whole Cape jasmine plant was 1:0.17~0.24:0.80~1.03. In the Cape jasmine fruit, the ratio was 1:0.21~0.23:1.34~1.51. Plant stems contained more N, P, and K (39.8 to 46.8% of plant total) than either the roots, leaves, or fruits. Jiangxi-24
