An experiment was carried out to evaluate performances of four tomato varieties (Bishola, Eshet, Marglobe and Moneymaker) harvested at ripe stage from greenhouse and open field condition at Jimma for post-harvest quality characters (total soluble solid, weight loss, titratable acidity, sugar-acid ratio, and pH). Bishola and Eshet had better chemical quality characteristics maintained throughout the end of the storage period. Varieties grown under open field condition showed highest fruit weight loss. The total soluble solid (TSS) values the open field grown tomatoes had highest than greenhouse grown tomatoes throughout storage period. The heighest TSS was obtained at 14 days storage  while the lowest was at harvest. Titratable acidity of tomatoes after harvest tended to decrease throughout the storage period. Bishola had highest titratable acidity when compared with Eshet. There was increase in sugar/acid ratio throughout storage time for greenhouse growing condition, under open field condition there is a slight increment and rapid after harvest and then decrease at 14 days the storage period. This indicates that Greenhouse grown tomatoes have good flavor than open field grown. Tomato varieties grown under greenhouse condition were less weight loss, and higher sugar acid ratio and less prone to physical injuries than fruits of grown under open field condition. Variety Eshet and Bishola could be selected in maintaining better overall quality characteristics.
