    Opis:
    The paper is based on the chosen results of two one-year field experiments which were conducted in the vicinity of Bydgoszcz (Poland) and in the vicinity of Cukurova (Turkey). The aim of the study is to present the comparison of yields of chosen watermelon cultivars grown in the different climatic-soil conditions under drip irrigation with N fertigation. The experiment in Turkey was carried out under better soil conditions than in Poland - watermelon plants were cultivated on the clay loam and fine sand, respectively. ‘Crimson Sweet' and ‘Sugar Baby' cultivars were tested in the experiment in Poland, and two other cultivars (‘Madera-F1', ‘Paladin-F1') were examined in the experiment in Turkey. Nitrogen of 120 kg N was applied in two different nitrogen forms (G - granule nitrogen; L - liquid nitrogen). In the second treatment (L), the liquid N fertilizer was given with irrigation water (fertigation). All plots were drip irrigated. Higher irrigation water rate was supplied in Turkey (251.7 mm) than that in Poland (157.5 mm). Average yields of watermelon ranged from 32.62 to 37.87 t.ha-1, and from 29.09 to 30.35 t.ha-1, in the experiment in Poland and in the experiment in Turkey, respec-tively. Yields were dependent on cultivar and treatment (experimental variant). The yields of ‘Crimson Sweet' and ‘Madera-F1' cultivars in treatment with combined N application (granule and liquid N) were higher than these of treatment with granule N source. Fruit weight ranged in both the trials from 3.0 to 5.5 kg. ‘Sugar Baby' and ‘Madera-F1' cultivars were characterized by the highest fruit weight (5.5 kg and 5.2 kg, respectively) under combined N application. From results, it can be concluded that watermelon yield could be increased by application of liquid N fertilizer. Amongst the four cultivars, ‘Crimson Sweet' and ‘Madera-F1' gave higher yields under conditions of applications of granule together with liquid nitrogen form.

    Opis:
    Intensified production of apples makes a fruit grower establish an orchard immediately after grubbing up an old one. Then, if replanting does not occur, stands for new trees can be significantly affected by soil properties conditioned by a long- term way of its management. Another problem in horticulture is water deficit. Due to diminishing water reserves there is a need to improve sorption capacity of soils. The use of polymer supersorbents provides one of possible solution to the mentioned problem. The aim of the work was the assessment of the effect of a long- term application of herbicide fallow, black foil, black agrotextile and pine bark in trees rows in an old orchard, on growth and fruiting of apple trees ‘Ligol' planted immediately after grubbing up the old trees. Research also involved potential modification of the above effect caused by rootstock type: M.9, M 26 and P 60, as well as by additionally applied agrogel. The growth and yielding of young trees ‘Ligol', related to a long-term system of soil management in the old orchard, was highly diversified and depended on the type of rootstock and agrogel applied. Yielding of the trees was also connected with the year of cultivation.

    Opis:
    This paper examines the changes in stocks of water in clay soils against precipitation and changes in the groundwater table. The study was conducted during the summer period (May-September) in 2001 and 2002. According to the Kaczorowska` s criteria (1962) the year 2001 was very wet, and the 2002 – average. In 2001, ground water table was at a depth of 0 to 190 cm below ground surface level, and in 2002, from 50 cm to 150 cm below the surface. Water storages in the root zone (0-35 cm) developed in 2001 at the level of 100 to 125 mm, in 2002, from 88 mm to 122 mm.

    Opis:
    In the climatic conditions of Poland the temporary lack of rainfall during the vegetation season, influenced on the water deficits in the top soil level. This situation can effect on the height and quality of yields in particular years. There is estimated that in the – so called – Large Valleys Region the water deficiency ranged 200-300 mm. Production of cucurbit’s vegetables in open field is strictly connected with thermal-rainfall conditions during the vegetation season. The optimal soil moisture is the very important factor for high and good quality yield. So, the production of the cucurbit plants should be connected with the irrigation installations. The aim of the study was to determine the influence of drip irrigation in cultivation of summer squash ‘Danka’ under light soil conditions. The trials were conducted in the years 2004 – 2006 at the experimental field in Kruszyn Krajeński near Bydgoszcz – on a soil of rye weak complex. The plot area for harvest was 9,1 m2. The irrigation rates were done on the base of soil water potential according to tensiometer indications. The irrigation was started when the soil water tension was – 0,04 MPa. The fruits of the summer squash were harvested in the technological maturity in the second decade of September in each year of the study. The single weight and number of the fruits as well as marketable yield from the unit area were estimated. In the pulp the dry matter, vitamin C, sugars and carotenoids content were determineted. It was found that drip irrigation significantly increased the marketable yield of fruits. The higher yield increases were detected in the years with lower rainfalls. The significant influence of drip irrigation on the content of vitamin C and sugars was stated. The dry matter and carotenoids content were higher in the fruits from the irrigated plots, but the difference was insignificant.
