Nitrate content in leaves of vegetable and herbal plants from home gardens of agrotourist farms

Abstrakt

The objective of the research study was to compare of the nitrate content in leafy vegetables (lettuce, spinach) and herbal plants (basil, peppermint, oregano and thyme) from the home gardens of agrotourist farms located in the Central Roztocze region. The obtained results have shown that the content of nitrates in the studied plants depended on the plant species, physiological phase of plant development and the method of plant cultivation. The content of nitrates in the leaves of studied plant species was the following: lettuce > spinach > basil > peppermint > oregano >> thyme. Plants cultivated by conventional method accumulated the largest amounts of nitrates; when integrated method was used, less nitrates were accumulated and when organic method was used, the content of accumulated nitrates was the smallest. At the early stage of vegetative development the plants contained twice as much nitrates as the plants at the ripe vegetative stage. At the juvenile vegetative stage the content of nitrates exceeded the legally permissible content in lettuce, spinach and basil from conventional and integrated gardens. At the ripe vegetative stage the content of nitrates in all the studied plant species did not exceed the legally permissible content of these compounds in leafy vegetables with a short vegetative term
