Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Agriculture - Department of Agricultural Engineering Summary: Onion is one of the important commercial vegetable crops grown on a large scale in many countries. As the onion bulbs are to be stored for long period for use during off - season, a considerable loss occurs by way of deteriorating, sprouting, and moisture evaporation during storage. The objective of this study were to study the effect of storage conditions on the properties and the quality parameters of onion bulbs, in objective to keep quality, reduce losses, prolong shelf life, keep the price stable during the year. The properties of onion bulbs as affected by storage conditions are equatorial and polar diameter, compression strength, hardness, dry matter, total soluble solids and total carbohydrates. The quality parameters of the onion bulbs to be studied were weight loss, deterioration, sprouting and marketable percentage. The results indicated that, the average temperature in center of onion pile during the storage period ranged between 16.73 to 28.61 {u02DA}C for the forced ventilation, where it was ranged between 18.18 to 31.03 {u02DA}C for the natural ventilation, while in traditional storage system ranged between 19.52 to 32.93 {u02DA}C
