Opis:
The work assesses heat resources in central-east Poland (2001-2019). As a measure of heat resources, the concept of growing degree days (GDD) was used. GDD is a useful tool for agriculture as it takes into account the aspects of local weather and, based on it, plant development can be predicted. Daily maximum and minimum air temperatures were used to calculate GDD at 7 stations using threshold base air temperatures of 0°C (commencement of the warm season) and 5°C (start of the period of active plant growth). The following basic characteristics of the distribution were calculated: arithmetic mean, minimum and maximum values as well as coefficient of variation. The direction and significance of changes of the heat resources were determined on the basis of linear trend equations. The significance of directional coefficient of the trend was estimated with t-Student test at the significance level of α = 0.05. The average air temperature during the growing season ranged from 14.6°C in Białystok and Białowieża to 15.6°C in Włodawa, its greatest increase being recorded in Włodawa and Siedlce (by 0.36°C per year). GDD increased from north to south in the study area, but the mean GDD varied considerably from one location to another. GDD0 and GDD5 showed an upward trend over the 2001-2019 period for the study region as a whole.

Opis:
The study analyses the activity of cambium and the increment of wood during one growing season of European beech (Fagus sylvatica L.) in the central part (region) of the Drahanská vrchovina, Czech Republic. The research plot was situated at an altitude of 630ma.s.l. The following parameters were studied: the beginning and end of cambial activity, differentiation of wood fibres and vessels and the total increment of wood during the growing season in six trees. Samples were taken during the growing season of 2010 in weekly intervals from the beginning of April to the end of October. The dormant cambium consisted of 5.3 cells on average; their number rose gradually after reactivation. The maximum number of cells (10 to 14, 9.1 on average) in the cambial zone persisted for 8 weeks; in mid-August the cambium ended its division activity, while the differentiation process continued till mid-September. The first fully lignified vessels were formed 5 to 6 weeks after their formation in the cambial zone. Vessels and adjacent wood fibres were the first elements to become fully lignified. The maximum production of cells (wood increment) was recorded from June 11 to June 24. 57% of the total ring width was formed in June. The mean ring width calculated by means of Gompertz function is 1777 μm (ranging from 1226 μm to 2423 μm).

Celem pracy była ocena zmian długości okresu wegetacyjnego w Polsce w wieloleciu 1971–2009 oraz w warunkach klimatycznych prognozowanych na lata 2030 i 2050. Długość okresu wegetacyjnego w latach 1971–2009 określono na podstawie danych dobowych z 48 stacji synoptycznych IMGW-PIB. Analizę zmian długości okresu wegetacyjnego w przyszłości wykonano dla dwóch miejscowości w Polsce: Grabowa (Polska Środkowa) i Laskowic (Polska Południowo-Zachodnia), według scenariuszy emisyjnych A1B i A2 i trzech modeli klimatycznych: ECHAM5/MPI–OM (ECHAM), HadCM3 (HadCM) i NCAR-PCM (NCAR). Wykazano, że w latach 2001–2009 okres wegetacyjny w Polsce był dłuższy o 8 dni niż w latach 1971–2000. Największe zmiany stwierdzono w północno-zachodniej Polsce, gdzie okres ten wydłużył się o ponad 9 dni, a w okolicach Koszalina i Ustki o 16 dni. Według przyjętych scenariuszy klimatycznych, w perspektywie 2030 r. okres wegetacyjny w środkowej Polsce będzie dłuższy o 10–14 dni niż w latach 1971–2000, a w perspektywie do 2050 r. – o 18–27 dni. W południowo-zachodniej Polsce długość okresu wegetacyjnego w perspektywie do 2030 r. wydłuży się o 11–17 dni, a perspektywie do 2050 r. – o 22–30 dni.
The aim of this study was to assess changes in the length of the growing season in Poland in the multi-year period of 1971–2009 and projected climate conditions for the years 2030 and 2050. The length of the growing season in the years of 1971–2009 was determined based on daily data from 48 synoptic stations of IMGW-PIB. The analysis of changes in the length of the growing season in the future was performed for two places in Poland: Grabów (Central Poland) and Laskowice (South-Western Poland), according to the emission scenarios A1B and A2 and three climate models: ECHAM5/MPI-OM (ECHAM), HadCM3 (HadCM) and NCAR-PCM (NCAR). It has been show that in the years of 2001–2009, growing season in Poland was by about 8 days longer than in the years 1971–2000. The biggest changes were found in north-western Poland, where the period was extended by more than 9 days, and near Koszalin and Ustka – by about 16 days. According to the climate scenarios adopted to the 2030, growing season in central Poland will be extended by about 10–14 days compared with that in the years 1971–2000, and by about 18–27 days in the 2050. In south-western Poland, the growing season in 2030 will be extended by about 11–17 days, and in the 2050 – by about 22–30 days.

This paper presents data on daily precipitation totals from six meteorological stations and the climatic water balance for the stations located throughout Poland in 2011-2015. The following sequences of days without precipitation were distinguished: from 11 to 15 days, from 16 to 20 days, and of more than 20 days. The number of precipitation-free sequences during the growing season in 2011-2015 was highly variable. Over the studied period, there were from 1.0 rainless sequence in Wtelno to 2.4 such sequences in Gołębiów per one growing season. The most frequently occurring were sequences of 11-15 days, while those of 16-20 days were less frequent. In the years under analysis, all of the different sequences occurred most frequently in July, and the least frequently in April. The highest numbers of sequences without precipitation were recorded in the south-east of Poland (Zakalniki, Gołębiów).

Opis:
This study presents the results of monitoring studies carried out to determine the chemical composition of Nuphar lutea in two phytocoenoses of Nupharo-Nymphaeetum albae Tomasz. 1977 occurring in two lakes of different trophic types (eutrophic Lake Łaśmiady and oligo-humotrophic Lake Pływające Wyspy). The leaves (collected starting in May), rhizomes and roots of Nuphar lutea as well as water and sediment samples were collected from March to November in the above phytocoenoses (for 3 years in Lake Pływające Wyspy and for 4 years in Lake Łaśmiady). The samples were analysed for several parameters including: phosphate, nitrate, total nitrogen, potassium, sodium, calcium, total iron, sulphate and silica dissolved. In addition the manganese, cadmium, zinc and lead contents were determined in the leaves, rhizomes and roots of the plants collected in July (at the height of the growing season). It was found that the differences in the chemical composition of water and sediments between the lakes studied were more pronounced than in the case of leaves, rhizomes and roots of Nuphar lutea.

Net ecosystem production reflects the potential of the ecosystem to sequestrate atmospheric CO2. Daily net ecosystem production of a mountain Norway spruce forest of the temperate zone (Czech Republic) was determined using the eddy covariance method. Growing season days when the ecosystem was a CO2 source were examined with respect to current weather conditions. During the 2005, 2006, and 2007 growing seasons, there were 44, 65, and 39 days, respectively, when the forest was a net CO2 source. The current weather conditions associated with CO2 release during the growing seasons were: cool and overcast conditions at the beginning or end of the growing seasons characterized by a 3-year mean net ecosystem production of -7.2 kg C ha-1 day-1; overcast or/and rainy days (-23.1 kg C ha-1 day-1); partly cloudy and hot days (-11.8 kg C ha-1 day-1); and overcast and hot days (-13.5 kg C ha-1 day-1). CO2 release was the highest during the overcast or/and rainy conditions (84%, average from all years), which had the greatest impact during the major production periods. As forests are important CO2 sinks and more frequent weather extremes are expected due to climate change, it is important to predict future forest carbon balances to study the influence of heightened variability in climatic variables.

Opis:
The work is based on meteorological data recorded by nine stations of the Institute of Meteorology and Water Management located in east-central Poland from 1971 to 2005. The region encompasses the North Podlasian Lowland and the South Podlasian Lowland. Average values of selected agroclimate indicators for the growing season were determined. Moreover, principal component analysis was conducted to indicate elements that exerted the greatest influence on the agroclimate. Also, cluster analysis was carried out to select stations with similar agroclimate. Ward method was used for clustering and the Euclidean distance was applied. Principal component analysis revealed that the agroclimate of east-central Poland was predominantly affected by climatic water balance, number of days of active plant growth, length of the farming period, and the average air temperature during the growing season (Apr-Sept). Based on the analysis, the region of east-central Poland was divided into two groups (areas) with different agroclimatic conditions. The first area comprized the following stations: Szepietowo and Białowieża located in the North Podlasian Lowland and Biała Podlaska situated in the northern part of the South Podlasian Lowland. This area was characterized by shorter farming periods and a lower average air temperature during the growing season. The other group included the remaining stations located in the western part of both the Lowlands which was warmer and where greater water deficits were recorded.

The aim of the study was to determine the effect of weather components (air temperature, precipitation) on the growth, yield and the length of the growing season of sweet corn cultivated in eastern Poland. The results come from a field experiment conducted in 2006–2011. Weather conditions in the successive years of the study significantly modified the yield of ears, weight and number of formatted ears, high of plants and the length of the growing season of sweet corn. Good yielding of sweet corn favoured years with moderate air temperatures in July and uniform distribution of precipitation during the growing season. The highest yield of ears was found in 2011, the lowest in the very difficult in terms of weather 2006. The shortest growing season was characterized corn grown in the years 2006 and 2010 with the high air temperatures in July and August, the longest in the years 2009 and 2011, in which the temperatures in the period June-August were the lowest of all the years of research. Irrespective of the year of study, cv ‘Sheba F1’ was formatted eras with higher weight than cv ‘Sweet Nugget F1’.

Opis:
The extraordinary knowledge of indigenous people about their immediate environment and natural resource base can be a great asset for conservation of biodiversity. The current study aims to investigate an indigenous method of grazing management through temporary confinement of Mithun (Bos frontalis) of whole village community in a well selected area in the forest during the cropping and growing season. The whole system is called Lura and practiced by Galo tribes of Eastern Himalayan region of India. Every year Lura management committee is formed that selects a new site based on number of Mithuns, forage availability, time period and several other key criteria without affecting flora-fauna diversity and rare medicinal plants. The practice checks continuous, free, random and selective grazing by Mithuns. It prevent continuous disturbance of soil surface due to treading, during growing and rainy seasons that avoid soil erosion and compaction, and facilitate seedling germination and the invasion by plants. Change of site, provide resting period to the forages in the previous Lura site especially during growth stage that allow them to renew and regenerate appreciably within 1-2 months. It also saves resources and time for construction of fencing in each Jhum and other agricultural site of each farmer. The confinement offers easy monitoring, protection and regular health assessment of the livestock. Thus, it is a multifaceted indigenous practice that ensures grazing management, biodiversity conservation, protection of standing agricultural crops and animal health management

Opis:
The research identified patterns in the multiannual course of start and end dates, and length of growing season (GS) in Central Europe since the end of the 19th century in selected cities of Central Europe in the period 1893–2020. GS start in the analysed stations was characterised by high year-to-year variability, particularly in those located more southwards, i.e. in Prague and Vienna. A smaller variability occurred in GS end dates. The GS was subject to prolongation, although these changes in particular cities were uneven and had different causes. In Toruń and Potsdam, its increase was caused by a greater shift of the end date, and in the remaining stations, it was determined by its earlier start date. Two subperiods were distinguished that differ in terms of intensity of changes of the start and end dates, as well as the length of the GS. The intensification was observed recently.

Opis:
Na podstawie przeprowadzonych doświadczeń z żytem stwierdzono, że faza krzewienia może przebiegać w stosunkowo niskich temperaturach. Gdy temperatura powietrza, mierzona na wysokości 2 m nad powierzchnią gruntu, wynosiła -3,2°C (średnia z 53 dni), przybyło 0,45 pędów żyta, gdy -2,5°C (średnia z 36 dni) - o prawie jeden pęd boczny, a gdy -2,5°C (średnia ze 175 dni) - o dwa pędy. Natomiast gdy temperatura wynosiła -0,4°C (średnia z 49 dni), liczba pędów zwiększyła się o 1,1, a gdy 1,2°C (średnia z 89 dni) - przybyło aż 11,6 pędów żyta. Krzewienie się w niskich temperaturach możliwe było w warunkach znacznej i długo zalegającej pokrywy śnieżnej, toteż rozwój roślin był uzależniony od temperatury najbliższego otoczenia. Proces krzewienia się następował już, gdy temperatura gleby wynosiła niewiele powyżej 0°C. Znaczne przyrosty liczby bocznych pędów żyta notowano w temperaturze niższej aż o 8,2 w 1998/1999 oraz 7,5°C w 1993/1994 i 1995/1996 od temperatury progowej 5°C, określającej początek i koniec wegetacji.
Growing season is a very important period in agriculture, which determines growth and yields of plants. The growing season commences when daily average air temperature is ≥ 5°C and ends when air temperature is ≥ 5°C. Experiments carried out with rye showed that a phase of tillering may proceed at a relatively low temperature. In a period of time, when air temperature measured 2 m above the ground surface was -3.2°C (average of 53 days), the number of shoots rose by 0.45, whereas at air temperature equal -0.4°C (average of 49 days) the number of shoots increased by 1.1 and by one shoot when air temperature was -2.5°C (average of 36 days). Furthermore, there were 11.6 more shoots when air temperature was 1.2°C (average of 89 days). The tillering of rye was possible at low temperature with considerably thick and long lasting snow cover. Growth of rye depended on temperature of the nearest surroundings (soil), the process of tillering occurred at a temperature just above 0°C. Remarkable increments in the number of side rye shoots were noticed at temperatures lower by 8.2 in 1998/1999 and 7.5°C in 1993/1994 and 1995/1996 then a threshold value of 5°C, which defines the beginning and the end of the growing season.
