The use of artificially synthesized inorganic manure for the production of fruits and vegetables gives rise to soil contamination as well as noxious effects against human. Changes in quality of strawberry (SN) cultivated with a natural organic manure developed to solve such problems were studied during storage at 4$^{circ}$C for 2 weeks. SN showed higher weight/volume ratio and lower weight loss during storage than strawberry (control) cultivated with commercial synthetic mature. Sweetness was higher in SN (9.2 Brix) than in control (8.2 Brix), and decrease in sweetness during storage was smaller in SN than in control. Redness (b) of strawberry was 32.1 in SN and 30.2 in control, and the redness decreased during storage showing 25.2 and 23.0, respectively, after 2 weeks. Hardness was higher in SN than in control, and decrease in hardness during storage was smaller in SN than in control. Vitamin C content was slightly higher in SN than in control, and mineral contents were generally higher in SN than in control.
