The experiments were carried out in 2004-2005 in The Experimental Farm Felin, Agricultural University in Lublin. The seedling was set into the field on 15 May 2004 and 12 May 2005. The first harvest of leaves was made on 30 July, second - 27 October. Plants were irrigated using dropping lines. Cultivation of leaf celery with no irrigation gave leaf yield at the level of 5.2-6.34 kg/m2; use of irrigation elevated it to 7.70-11.97 kg/m2. Closer spacing between leaf celery seedlings caused a significant increase of leaf yield. The highest yield of leaves was obtained from Safir cv.
