A Quantitative Management of Potassium Supply for Hydroponic Production of Low-Potassium Cherry-Type Tomato Fruit for Chronic Kidney Disease Patients

Chronic kidney disease (CKD) has been a global health problem in recent years. CKD patients often restrict their potassium (K) intake to avoid the high risk of hyperkalemia. In this study, quantitative K management hydroponics was adopted produce low cherry-type tomato (Solanum lycopersicom L.) fruit. The total quantity supply per plant during cultivation 7.2 g (1 K), 3.6 (1/2 1.8 (1/4 0.9 (1/8 K) and 0.6 (1/12 respectively. fruit yield decreased about 75% at 1/2 58% 1/12 compared 1 K. content lower 1/4 K, 1/8 than from achieved below 100 mg g−1 FW Total soluble solid (Brix) 7–8% but Fruit acid 87% 70% 57% conclusion, is expected approximately mg.100 when with relatively smaller effect on yield, Brix content.
