The aim of the paper is to provide climatic data from the basic elements and characteristics of the energy balance in terms of the current state and in terms of trends and assumptions of their future changes in Slovakia. Climate change affect agriculture and its procedures. Changes in vegetation period in Slovakia of selected vegetables are presented in this study. We used for agro-climatic analysis one hundred climatological stations, which were selected to cover all agricultural regions up to 800 m a.s.l. Actual data and predictions were compared with time period 1961–2010. Due to homogeneity in data measurements, was chosen this period. We obtained climate trends and assumed map outputs of future climate changes by mathematical-statistical methods for horizons of years 2011–2020, 2041–2050, 2071–2080 and 2091–2100. We analysed vegetation period changes of selected fruit vegetables, Brassica vegetables and root vegetable in field conditions with prediction to year 2100. In our results is shown the earlier beginning of vegetation period in a spring and later end in an autumn in last 30 years. The vegetation period is getting longer about 15–20 days for Capsicum annuum; 15–20 days for Brassica oleracea var. capitate; 10–15 days for Beta vulgaris subsp. vulgaris with comparation of nowadays situation and period 2091–2100.

The results of research on the influence of plant standing density and level of mineral fertilization on growth and development of sweet corn plants of hybrid Moreland F1 on sod–podzolic soils have been presented. The change in influence degree of technological factors on the height of sweet corn plants in different periods of the crop growth and development has been established. It was determined that the longest vegetation period had the crops of sweet corn grown under conditions of full mineral fertilization and maximum plant density of 80.000/ha – 80.3 days, and the shortest one was on the variant with unfertilized background and plant density of 60.000/ha – 73.2 days. Increase of mineral fertilizer dose contributed to better growth of sweet corn than in variants without mineral fertilizers. Increase of plant density up to 80.000/ha led to unnatural stretching of plants (over 190 cm). It was determined that the optimal plant height of the crops was at the density of 60 thousand/ha on the background of nutrition N135P90K125 + N60 + N30. The maximum average daily growth was characterized by sweet corn plants on the background of nutrition N135P90K125 + N60 + N30 with plant density 80.000/ha – 2.93 cm.

Maize has very homogenous grain which is considered to be the best animal feed in the world, characterized by the highest availability of energy and other nutrient elements. However, the conditions of the habitat, species characteristics and caryopsis structure can modify the contents of mineral elements in grain. The literature lacks reports identifying the influence of the harvest date and cultivar on the microelement content in maize grain. The experiments were conducted between the years 2003-2005, in the fields of the Swadzim Research and Didactic Institute, belonging to the Department of Soil and Plant Cultivation of Poznań University of Life Sciences. Their aim was to determine changes in the content of selected microelements in grain of six maize cultivars differing in the lenght of vegetation time and type of grain due to delays in the harvest date. The experiment was bifactor in 4 field repetitions. The first order factor was the date of harvest: 1st - the „black spot” stadium in ripening caryopsis; 2nd - 6th - further harvests performed fortnightly. The second order factor was the cultivar; the selected cultivars differed in the terms of earliness and type of grain. „Dent” cultivars were PR39T68 (FAO 200), Blask (FAO 240-250), Clarica (FAO 270). „Flint” cultivars were Oleńka (FAO 200), Matilda (FAO 240), Anjou 258 (FAO 260-270). On average the highest content of Cu and Fe was recorded in grain harvested six weeks after the „black spot” phase, and Mn and Zn in grain harvested four weeks after this phase. Among the tested cultivars the highest content of Cu and Fe was recorded for the medium early cultivar Blask, and Mn and Zn for the early cultivar Oleńka.

Kukurydza charakteryzuje się bardzo jednorodnym ziarnem, które uważane jest za najlepszą paszę na świecie, charakteryzującą się największą dostępnością energii oraz składników pokarmowych. Należy jednak zwrócić uwagę, że warunki siedliska, właściwości gatunkowe oraz budowa ziarniaków może modyfikować zawartość składników mineralnych w ziarnie. W literaturze brakuje doniesień określających wpływ terminu zbioru oraz odmiany na zawartość mikroelementów w ziarnie kukurydzy. Doświadczenia przeprowadzono w latach 2003-2005, na polach Zakładu Doświadczalno-Dydaktycznego w Swadzimiu należących do Uniwersytetu Przyrodniczego w Poznaniu. Badania wykonano w celu określenia zmian w zawartości wybranych mikroelementów w ziarnie sześciu mieszańców kukurydzy różniących się długością okresu wegetacji i typem ziarna, wynikających z opóźniania terminu zbioru. Doświadczenia wykonano jako 2-czynnikowe, w 4 powtórzeniach polowych. Czynnikiem 1-go rzędu był termin zbioru: I termin - stadium czarnej plamki w dojrzewających ziarniakach; II - VI - kolejne terminy zbioru: co dwa tygodnie. Czynnikiem 2-go rzędu była odmiana, dobrano mieszańce różniące się wczesnością oraz typem ziarna. Odmiany „dent”: PR39T68 (FAO 200), Blask (FAO 240-250), Clarica (FAO 270). Odmiany „flint”: Oleńka (FAO 200), Matilda (FAO 240), Anjou 258 (FAO 260-270). Średnio dla odmian najwyższe zawartości Cu i Fe odnotowano w ziarnie zebranym sześć tygodni po stadium „czarnej plamki”, a w przypadku Mn i Zn w zebranym po czterech tygodniach od tej fazy. Spośród ocenianych odmian, najwyższą zawartością Cu i Fe cechował się średniowczesny mieszaniec Blask, a Mn i Zn wczesna odmiana Oleńka.

The research results of using growth regulators with anti-stress action which stimulated growth and development of plants, and provided them with resistance to adverse factors during the vegetation period, were presented. The use of plant growth regulators with anti–stress effect on Sinapis alba L. increased the plant resistance to adverse environmental influences, providing adaptation to changing environmental conditions, i.e. it has a stress–correcting effect throughout the whole vegetation period. The result of using drugs on mustard (Sinapis alba L.) was obtaining a significant and stable additional seed yield (0.57 t·ha-1), i.e. an increase in yield by 38%. Over the years of research, the most effective were the applications of Fast Start and Biofoge growth regulators. The most effective processing terms were: during the vegetation period as well as combination of seed treatment and application during the vegetation period.

Future of beech (Fagus sylvatica L.) in a changing climate is one of the greatest debates in Europe among the studies dealing with the climate change generated xeric limit shifting. We investigated a submontane beech stand’s growth response to climate change in Northern Hungary during the past 60 years following dendrochronological methods. Tree-ring width data were processed using three alternatives of standardization. To recover the basic climate-growth relationships for beech we analyzed the correlation between the tree-ring width indices and monthly precipitation and temperature data, furthermore two drought indices were employed. Late spring-early summer precipitation was the primary climatic factor governing the beech growth at the study site since the early 1950s, while summer heat played a secondary obstructive role documented by the significant negative correlation. A 30-years running window correlation was used to identify whether the climate-growth connections changed due to the unfavorable climatic trends. The results indicated no evidence of a distinct decline in radial increment, however, a significant increase in climatic impact on growth has been detected including probable changes and shifts in the vegetation period.

Wyznaczono daty początku i końca oraz liczbę dni okresu wegetacyjnego (1971-2005). Ponadto analizie poddano średnie miesięczne wartości temperatury powietrza po-szczególnych miesięcy okresu wegetacyjnego. Kierunek oraz istotność tendencji zmian określono na podstawie równań trendu liniowego. Termiczny okres wegetacyjny w środkowo-wschodniej Polsce rozpoczynał się około 28 III i trwał do 30 X. Południowo-zachodnia część badanego obszaru charakteryzowała się najwyższą średnią temperaturą powietrza okresu wegetacyjnego (IV-X), a północno-wschodnia najniższą. W większości analizowanych stacji w kwietniu, lipcu i sierpniu zanotowano dodatnie istotne statystycznie zmiany temperatury powietrza. Najwyższy wzrost tego parametru (średnio o 0,7oC na 10 lat) zanotowano w kwietniu. W stacjach położonych we wschod-niej części badanego regionu istotny (średnio o 0,4oC na 10 lat) wzrost temperatury wystąpił rów-nież w październiku.

The beginning and ending dates as well as the number of days of vegetation period were determined. Average monthly air temperature values of particular months during the vegeta-tion period were analysed. The direction and significance of tendency of changes were determined on the basis of linear trend equations. Thermal vegetation period in central-eastern Poland began around March 28th and lasted till October 30th. South-western part of the area examined was charac-terised by the highest average air temperature of the vegetation period (IV-X), while north-eastern part – by the lowest. In most of the stations analysed, statistically significant changes of air tempera-ture were noted in April, July and August. The highest increase of this parameter (on average of 0.7oC for 10 years) was noted in April. In stations located in the eastern part of the region examined a significant increase of temperature (on average of 0.4oC for 10 years) occurred also in October.

Our experiment was carried out in experimental plots of the Vegetable Experimental Station of the Agricultural University in Mydlniki near Kraków, Poland in 2008-10. The year 2008 was characterized by the driest season of all three years, whereas in the other years of the study the vegetation season seemed moderately humid. Based on the analyses of regression, we found a significant influence of pluvial and thermal conditions on the fruit quality features of tomatoes. A directly proportional relationship between the hydrothermal index (K) and the number of seed chambers, dry matter, and content of lycopene, magnesium, and calcium of the tomato fruit was observed. However, the relationship between the hydrothermal index (K) and fruit weight, potassium content, and total acidity turned out to be inversely proportional. The impact of the hydrothermal conditions on the thickness of the pericarp, the shape coefficient, phosphorus; L-ascorbic acid content, and the reducing sugars of the fruits was not observed. The value distribution of the tested tomato features in all of the years of the experiment points to the different sensitivities of individual tomato cultivars to thermal and precipitation conditions. The aim of this study was to determine the influence of hydrothermal conditions represented by the hydrothermal index (K) on the morphological features of tomato fruits and their chemical composition.
