The objective of this study was to investigate the effect of applying different K/N ratios of irrigation fertilizer from selfproducing organic liquid fertilizer on the yield and quality of greenhouse organic tomato in soilless culture, and to choose suitable K/N ratio of irrigation fertilizer. The treatments included: (1) K/N unadjusted; (2) K/N = 3; (3) K/N = 6 and (4) Yamasaki formula (Control). The experiment was Randomized Complete Block Design (RCBD) with four different treatments and four replications. The results showed the total fruit weight, total fruit numbers, each fruit weight, total soluble solids, titratable acidity, and sugar-acid ratio among the treatments with different K/N ratios of irrigation fertilizer were not significantly different, and all of them were also not significantly different from Control. The result of tomato leave analysis indicated the treatments applying higher K/N ratios of irrigation fertilizer with palm ash filtrate containing abundant K resulted in significantly increased K content in tomato leave, and the content was close to Control. There was no significant difference observed. It was concluded that self-producing organic liquid fertilizer after proper dilution could be used as the irrigation fertilizer of greenhouse organic tomato in soilless culture, and didn't need to add K.
