abstract:
In 2004-2005 a pot experiment with Satureja hortensis L. was carried out. The effect of different forms of potassium fertilizer: KCl, K2SO4, KCl+ K2SO4 and various doses of nitrogen: 0,2; 0,4; 0,8 g dm-3 on the height of herb crop, on the content of the essential oil and on some nutrients content in the herb was investigated. The analysis showed significant effects of nitrogen doses on the height of the herb crop and on the content of main minerals in plant. The highest herb crop (154,1 g f.m.) was found in application of medium dose of nitrogen with K2SO4. The investigated factors did not influence the content of the essential oil in herb, and its content in the herb savoury varied within the limits from 1.15 to 1.69% s.m..
