abstract:
The effect of nitrogen-potassium fertilization on the yield of the herb Origanum majorana L., height of plants, content of the essential oil and on the mineral composition was studied in the years 2004-2005. In a pot experiment nitrogen fertilization was applied in the following doses: 0.2, 0.4 and 0,8 g N dm-3, and the following potassium fertilizers: KCl, K2SO4, KCl + K2SO4. Increasing nitrogen nutrition had a significant effect on the herb yield, on the height of plants, on the content of the essential oil and on the mineral composition (N-total, N-NO3, Ca, Mg). The highest yield of fresh matter (61.5 g N plant-1) was obtained using 0.4 g N dm-3 with KCl, while the highest content of essential oil (2,95%) was obtained using 0.8 g N dm-3 with K2SO4.
