This experiment was designed to understand the effects of different kinds (KNO_3, K2SO_4, KCl) and amounts of potassium fertilizers on the yield and quality of Wentan pomelo. The experiment was conducted in 1995 at Juisui, where is one of the most important Wentan pomelo production areas in Taiwan. In the contents of fruit juice, the results showed the treatment of applying 0.6kg K_2SO_4 per plant (contained 0.3kg K_2O) had the biggest volume of fruit juice (156cc/fruit), the treatment of applying 0.5kg KC1 (contained 0.3kg K_2O) was the second, and the lowest of that (121cc/fruit ) was obtained from the treatment of applying ＂0.9kg KNO_3 (contained 0.3kg K_2O) .In the contents of sugar, the treatment of applying 0.6kg K_2SO_4 had the highest value (12.4 Brix), the treatment of applying 1.2kg K_2SO_4 was the second, and the lowest sugar content was obtained from the treatment of 1.0kg KC1 (9.8 Brix ). The results of acidity obtained from all treatments were not significantly different. On fruit yield, the highest amount of production was obtained by the treatment of applying 0.6kg K_2SO_4; the treatment of applying 1.2kg K_2SO_4 was the second; while the treatment of applying 0.9kg KNO_3 was the lowest. Generally speaking, applying 0.6kg K_2SO_4 per plant each year could be the best way to improve the quality and got high yielding of Wentan pomelo, compared with other potassium fertilizers.
