Effect of potassium and magnesium on sugarcane yield and quality in Yunnan province

IPNI-1998-CHN-YN8

Effect of potassium and magnesium on sugarcane yield and quality in Yunnan province, 1998 Yunnan has traditionally been an important sugarcane production area in China. Despite the region's favorable climate, imbalanced fertilization is severely reducing yield potential and cane sugar content. In Baoshan county, the combination of 525 kg K2O/ha with 350-202-60-60 kg N-P2O5-S-Mg/ha (i. e. , -K treatment) increased yields from 108 to 167 t/ha and sugar content from 11. 9 to 13. 9 percent.
