The onion (Allium cepa L.),is an herbaceous plant with a reduced stem with enormous leaves, a fleshy and swollen base that constitutes the bulb, rich in nutrients. The first references date back to about 3 200 BC, when they were cultivated by the Egyptians, Greeks and Romans. In the MiddleAges it was cultivated in the Mediterranean, where the large bulb varieties were selected. It occupies the second place according to the volume produced, (after tomato), as the main vegetables worldwide. Latin America represents 9% of world production, the largest producers being Mexico, Brazil and Argentina. The main objective of the study is to determine the chemical composition of three varieties grown in the province of Chiriquí: the varieties Gladalan Brown, Regia and Seilux.Percentage of moisture, ash, protein, crude fiber, fat, carbohydrate and macros and micro elements are determined. In our country, onion cultivation has had great relevance since 1950, but we are not yet self-sufficient.
