The effect of the cultivation methods on the chemical composition of garlic

Knowledge of the chemical composition of vegetables and its continuous analysis is extremely important due to the constant introduction of changes that optimize the crop, primarily in terms of fertilization and protection measures used. Garlic is characterized by a rich chemical composition. It contains numerous micro- and macroelements (potassium, phosphorus, magnesium, iron, calcium, zinc, copper, nickel, cobalt, chromium, selenium, boron and germanium) and vitamins (C, A, PP, B vitamins). Garlic can be grown by several methods, differing in size and place of cultivation and method of fertilization. Taking this into account, in the submitted work, tests were carried out to verify the composition of garlic from home cultivation, allotment cultivation (with natural and mineral fertilization) and from industrial cultivation. The content of vitamins, light metals, total phosphorus and microelements was determined. The host was also interviewed as a reliable source of supplementary information. On the basis of the obtained research results, it was found that organic cultivation of garlic produces a crop with the richest chemical composition, compared to other crops, including in particular industrial cultivation. Garlic samples from organic farming were distinguished by the highest content of vitamin C, B1, potassium and phosphorus.
