EN

The effect of different nitrogen fertilizer (potassium nitrate, ammonium nitrate, ammonium sulphate, urea and farmyard manure) on nitrate reductase activity in cabbage (Brassica oleracea var. capitata) seedlings were studied. pH of the plant growth media was higher in the nitrate fertilizer treatment than the ammonium and other fertilizer forms. NO3--N application increased NRA in plant, but NH4+ -N decreased NRA in plant. Harvesting date and different fertilizer doses increased NRA while NH/ -N decreased plant nitrate uptake. There was a significant relationship between NRA and fertilizer types.

PL

Badano wpływ różnych rodzajów nawozów azotowych (azotan potasu, azotan amonu, siarczan amonu i mocznik) oraz obornika na aktywność reduktazy azotanowej w siewkach kapusty głowiastej (Brassica oleracea var. capitata). Stosowanie nawozów azotanowych zwiększało aktywność enzymu w roślinach, podczas gdy użycie nawozów amonowych - obniżało. Zależność między aktywnością reduktazy azotanowej i rodzajami nawozów azotowych była istotna.
