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.

This experiment, carried out in a greenhouse from February to May in 2008-2010, was designed to determine the effect of an increased rate of nitrogen and potassium on the content of phosphorus, calcium, magnesium, chlorine and sulphur in basil herbage as well as to trace relationships between a basil cultivar and changes in the mineral composition of the herbage as influenced by the applied rates of nutrients. The mineral composition of basil herbage was determined on the basis of an analysis of the growing substrate conducted after the harvest of the experimental plants. Two Polish cultivars of basil, called Kasia and Wala, as well as a green-leaved form popular on the domestic horticultural market, were grown from seedlings in pots (4 dm 3 ) filled with sphagnum peat of the pH between 5.5-6.0. The following amounts of nutrients were applied, expressed in g per 1 dm 3 of the growing substrate: 0.2, 0.4, 0.6, 0.9 N in the form of ammonium nitrate; 0.4, 0.8 K in the form of potassium sulphate; 0.4 P as 20% P superphosphate; 0. rate of nitrogen resulted in an increased concentration of the mineral nutrients determined in the basil herbage. The magnesium concentration in the basil herbage dry matter was not dependent on a cultivar and nitrogen rate, but increased under the influence of the higher amount of potassium applied. On the other hand, the raised amounts of potassium did not modify the concentrations of phosphorus and sulphur in the examined plant material.Key words: Ocimum basilicum L., cultivar, nitrogen and potassium fertilization.

The aim of the present study was to determine the relation between the quality of seed germination and morphological differentiation of seedlings of the studied tomato cultivars. The seeds of very early tomato cultivars (Beta, Betalux. Promyk) compared to the semi-early New Yorker cultivar treated as control were subjected to evaluation. lt was found out that their germination rate significantly affected the quantity of obtained seedlings. The seedlings gr()wii ~oiii seeds that germinated after 5 days were significantly higher than those that germinated after 7 0r l0 days. They also had higher number of leaves. larger diameter of root collar and higher fresh mass.

The influence of seed germination dynamics on selected features of the seedling of 4 tomato cultivars (Beta, Betalux, Promyk, New Yorker) meant for field cultivation were investigated. It was shown that flowering was the earliest in combinations with plants received from the seeds of the fastest germination, while the greatest delay of flowering was observed in plants received from the seeds of the longest germination (after 10 days). Plants grown from the seeds which had germinated the fastest were significantly higher, had greater average number of leaves, and had greater mass than plants from the seeds germinating longer. Further observations carried out at the moment of flowering of plants of all combinations did not show any significant differences in terms of investigated features except average height of plants.
