Lobelia inflata L. is a medicinally important species of the Lobeliaceae family. It is native to North America and contains numerous piperidine alkaloids. The main alkaloid lobeline is used as a respiratory stimulant. The aim of our studies was to examine lobeline production of L. inflata in open field conditions. The nutrients were applied in the following methods and quantities in 2011 and in 2012: untreated (control), 50 kg/ha Nitrogen-, 100 kg/ha Nitrogen ground fertilizer, 50 kg/ha Mgand 100 kg/ha Mg ground fertilizers.
