Reaction of Leaf Celery (Apium Graveolens L. Var. Secalinum) To Planting Density and Irrigation

In experiments conducted in the years 2004-2005, effect of seedlings planting density and irrigation on yield of 2 cultivars of leaf celery (Afina, Safir) was evaluated. Transplants were planted on 15 May 2004 and 12 May 2005 with spacing 25 x 20 cm and 15 x 20 cm. Harvest of celery leaves was carried out in three turns: on 15 July, 14-15 September and 27-28 October. It was shown that higher planting density significantly increases yield of leaves. Irrigation increased leaf yield, on average, by 55.9%. Depending on cultivar and planting density, leaf yield of non-irrigated plants was 5.29-6.34 kg^.m^-2, while for irrigated plants it ranged from 7.70 to 11.97 kg^.m^-2.
