Lysimeters represent the ideal tool for direct measurement of soil water balance components in soil profiles. Changes in the water content in a soil monolith can be measured with sufficient accuracy by the precise lysimeter weighing system. Water content changes in soil monolith as derived from lysimeter mass represent one of the basic water balance component. This paper deals with the development and comparison of individual soil water balance components in two different soil profiles from the Easter-Slovakian-Lowland. Two lysimeter vessels were filled monolithically with two different soil profiles covered with grass: one sandy soil profile from locality Poľany and one silty-loam soil profile from locality Vysoká nad Uhom. A constant groundwater level of 1 m below ground level was maintained in both soil profiles. Under the same meteorological conditions, all differences in the development of water balance components were caused only by the differences in soil profiles. The actual evapotranspiration and water flows at the bottom of the soil profiles were compared. Sandy soils are generally considered to be more prone to drought than silty-loam soils. Under the specific conditions of this experiment (maintaining a constant groundwater level) the opposite was shown, when the silty-loam soil profile was more prone to drought than sandy soil profile. Sandy soil profile from Poľany reacted more quickly to precipitation (or evaporation). Due to the higher hydraulic conductivity of the sandy soil compared to the silty-loamy soil, the groundwater level response to external stimuli was much faster.

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).

W pracy oszacowano zmienność klimatycznego bilansu wodnego terenów rolniczych w ujęciu sezonowym na podstawie danych meteorologicznych, danych o strukturze upraw w dawnym woj. poznańskim i przebiegu rozwoju szaty roślinnej. Bilans ten wyznaczono dla okolic Poznania, wybierając lata o opadach zdecydowanie wyższych lub niższych od średniej z wielolecia 1973-2002. Do obliczeń posłużono się matematycznym modelem bilansu cieplnego (MBC) powierzchni czynnej, opracowanym w Katedrze Agrometeorologii Akademii Rolniczej w Poznaniu. Na podstawie analizy rocznych przebiegów kumulowanego klimatycznego bilansu wodnego stwierdzono, że na ogół w maju następuje zrównanie ilości wody pochodzącej z opadów z ilością wyparowaną od początku roku. Dalszy przebieg wartości kumulowanego klimatycznego bilansu wodnego zależy od ilości opadów ? jeżeli opady przewyższają średnią z wielolecia, to pokrywają potrzeby ewapotranspiracyjne roślin, jeżeli jest ich mniej, zaczyna pogłębiać się deficyt wody. W latach mokrych dopiero jesienne opady po ustaniu wegetacji tworzą wyraźną nadwyżkę wody w środowisku, podczas gdy w latach suchych rok kończy się deficytem.

Annual variability of climatic water balance calculated for agricultural and forest areas of Poznań Province is presented in the paper. The calculation of climatic water balance was based on meteorological data, the structure of croplands and forest areas and on the growth stages of plants. The balance was estimated for three selected years with precipitation markedly exceeding the long-term (1973-2002) average and for another three years with precipitation beneath this average. The mathematic model of heat balance of active surface, made in Agrometeorology Department of the Agricultural University of Poznań, was used in calculations. Annual cumulative climatic balance presented in the paper showed that equilibration of precipitation water with that evaporated since the beginning of the year usually took place in May. Further course of the balance depended mainly on the amount of precipitation. Evapotranspiration requirements of plants were satisfied only during the periods with abundant precipitation. However, when precipitation was low, the water deficit deepened. In wet years, a significant surplus of water was formed not earlier than with the autumn precipitations, in dry years - the year ended up with water deficit.

The purpose of this study was to estimate the water needs of grapevines in central Poland in 1981-2010. Water needs were calculated by the plant coefficients, which were assumed according to the Doorenbos and Pruitt method. Reference evapotranspiration was assessed by the Blaney-Criddle’s equation, modified for Polish conditions. Rainfall deficit with the occurrence probability of normal, medium dry and very dry years was determined by the Ostromęcki’s method. Water needs of grapevines during the growing season was 434 mm. Upward time trend in the water needs both in the periods May-October and June-August was estimated. Temporal variability in the water needs was significant for most of the provinces. The rainfall deficit was recorded with the occurrence probability of normal as well as medium or very dry years in the entire study area. Due to climate changes, vineyards will require irrigation in the near future. This research significantly broadens and refines the knowledge about the water needs of grapevines in central Poland, which will allow the design of resource-efficient irrigation programs for grapevines in the studied region of Poland.

The aim of the study was to compare the water requirements and the precipitation deficiencies during cultivation of asparagus in the period from June to August in the regions of Bydgoszcz and Wroclaw. The water needs were calculated using the plant coefficient. The reference evapotranspiration was measured by Grabarczyk’s method (1976). The coefficients kc, determined for the Polish conditions by Rolbiecki (2013), were used to estimate the water requirements considered as the crop evapotranspiration. In the studied period (from June to August, 1996-2015), higher water requirements of asparagus were noted in the Wroclaw region (366.1 mm) than in the Bydgoszcz region (288.5 mm). The monthly water needs in June, July and August were 69.8 mm, 128.8 mm and 167.5 mm, respectively, in the Wroclaw region, and 55.5 mm, 98.5 mm and 134.5 mm, respectively, in the Bydgoszcz region. In July, the tendency to increase the water requirements in both observed regions was noted. The monthly crop evapotranspiration in July rose in each decade by 12.3 mm in the Bydgoszcz region and by 21.2 mm in the Wroclaw region. In the 20-year study, the rainfall deficit in June and July during 11-13 years was noted. In August, the precipitation deficiencies were observed during 16 years in the Bydgoszcz region and during 19 years in the Wroclaw region. A higher rainfall deficit during the 20-year period under study was reported in the Wroclaw region (128.5 mm) than in the Bydgoszcz region (87.0 mm). In August, the highest monthly precipitation deficiencies of 100.3 mm (Wroclaw region) and 70.3 mm (Bydgoszcz region) were noted.

At present, the sludge drying beds of the Kyiv wastewater treatment plants are operated as a sludge accumulator in an emergency mode, practically without free volume. The purpose of the work was to determine the equation for the evaporation losses calculation from sludge drying beds and the required free volume for sludge accumulation for the next 7 years. The required free volume was calculated using the water budget method which takes into account evaporation from the water surface and evapotranspiration during the vegetation. The total losses from sludge drying beds is 1076 mm/year in normal year and is 920 mm/year in a cold year. The required free volume was calculated considering the trend of increasing average temperature over the last decade and considering the significant environmental risk. A correction was made for one unfavourable year with cold summer and warm winter and an additional rain rate of 1% probability. The additional free volume required is 3.24 million m3 for 7 years if all three sludge drying beds are operated.

Global climate change has led to significant shifts in local climatic conditions of Ukraine with the trend to aridity aggravation. Sustainable crop production is at risk due to the aridity level increase. The study is aimed to evaluate aridity index in Ukraine (on the whole country and individual regions’ scales) and the needs in irrigation using hydro-meteorological data of the key regional stations for the periods of 1961-1990 and 2010-2020. The results of hydro-meteorological evaluation were supported by the data on the soil moisture regimes provided by Soil Explorer service. The general trend to aridity aggravation in Ukraine was proved. It was found out that modern climate in most territory of Ukraine is semi-arid, dry subhumid and humid zones are observed in the western regions only. Humid soil moisture regimes (ustic and udic) are observed in the West and the North of the country. As a result of combined analysis of both aridity index and soil moisture regimes the conclusion was drawn that 46.05% of Ukrainian croplands cannot provide sustainable crop production without irrigation, 42.65% need irrigation for the cultivation of crops with high water use, and just 11.30% of the arable land require little or no irrigation.

The aim of this study was to estimate the water needs of grapevines (Vitis vinifera L.) in the different regions of Poland. The requirements of grapevines water, considered as the crop evapotranspiration, were determined using the plant coefficient method. The grapevine plants crop evapotranspiration was measured using the reference evapotranspiration and plant coefficients. The plant coefficients were adapted to the reference evapotranspiration that was calculated using the Blaney‑Criddle’s formula, modified for Polish conditions by Żakowicz. The water needs of grapevines were determined for five agro‑climatic regions of Poland with the representative meteorological stations. The calculations of grapevines water requirements were carried out for the thirty‑year period determined from 1981 to 2010. The study was based on the six‑month growing season established from May 1 to October 31. Four months, including May, June, July and August, were considered as the irrigation period. The highest grapevines water requirements (440 mm) during the growing season, were observed in the north‑west and central‑east region of Poland. In turn, the lowest water requirements were revealed in the south‑east (414 mm) and north‑east (415 mm) region of the country. During the irrigation period, the highest grapevines water needs occurred in the central‑north‑west (355 mm) and central‑east (353 mm) region of Poland, while the lowest (329 mm) – in the south‑east region of the country. The upward time trend of the grapevines water requirements was observed both in the growing season and in the irrigation period. With the exception of the central‑north‑west region, this time trend was significant throughout Poland. The highest increase in the water needs of grapevines during the growing season (by 6.9 mm in each subsequent ten‑year period) occurred in the central‑east and south‑east region of Poland. In the irrigation period, the highest rise of grapevines water requirements was noted in the south‑west (7.4 mm decade ‑1) and south‑east (7.6 mm decade ‑1) region of the country. The highest rainfall deficit was observed in the central‑north‑west region of Poland; 125 mm during the growing season, and 117 mm in the irrigation period.

Satellite-based irrigation performance is a valuable tool for improving yields in irrigated areas across the world and requires adequate land for long-term development. This study aimed to increase irrigation performance and yield gap variation of rainfed crops using the database of FAO’s Water Productivity Open Access Portal (WaPOR) and the Global Yield Gap Atlas. The evapotranspiration (ET) performance of irrigation is expressed in equity (CV of ET), reliability, adequacy (CV of ET), and water productivity (kg∙m-3). The rainfed crops are interpreted in terms of metric tonnes/ha. Specifically, 20,325 km2 of suitable pastoral land across eight sub-classes was converted to rainfed rice, sugarcane, maize, and vegetable crops. Results showed that the R2 value was 0.97 at Baro Itang and -0.99 at Sor Metu, with the Baro Gambella sub-catchment having the largest yield gap of 4.435.2, 8.870.4, and 10.080∙106 kg when the yield increased by 1/3, 2/3, and 3/4. On the other hand, Gumero Gore had the smallest yield gap of 10,690, 29,700, and 33,750 kg, respectively. The management regime was 2.87, 0.87, and 0.35 kg∙m-3 for growers in the estate, farmer association, and individual, respectively. The study concludes that no single irrigation technique can be considered the best, and a thorough analysis of spatiotemporal variation of the irrigation performance indicators and the yield gap in the water-scarce lower Baro watershed is required.

Drought is regarded as one of the environmental constraints threatening agriculture worldwide. Melatonin is a pleiotropic molecule prevalent in plants capable of promoting plant endogenous resilience to many environmental challenges including drought. Banana is an important staple food consumed in developing countries especially in Africa. In this research, we studied the role of melatonin in the growth of bananas subjected to drought under the Egyptian semi-arid conditions. To achieve this objective, a field experiment on banana (Musa spp., cv. Williams) mother plants and first ratoon was conducted on a private farm for two seasons - 2019 and 2020. Three irrigation treatments, 100, 90 and 80% irrigation water requirements (IWR) were used in conjunction with four concentrations of melatonin as a foliar spray (0 μmol, 40 μmol, 60 μmol, and 80 μmol) to determine the effect of both treatments on banana plant performance under drought. The results showed that there was a substantial difference between treatments, with the foliar application of melatonin at 80 μmol concentration improving most of the yield attributes, relative water content, total chlorophyll and proline with water deficit. However, the foliar application of the molecule lowered the biochemical characteristics mostly at 80% IWR under the Egyptian semi-arid conditions. Overall, there was a concentration-dependent response with regards to IWR for the two seasons 2019 and 2020.

Presented paper analyses climate trends in Poland in the second half of the 20th century. Measurements of climate elements were obtained from 5 meteorological stations evenly distributed over Poland (Szczecin 53°24'N - 14°37'E, Wrocław 51°08'N - 16°59'E, Łódź 51°44'N - 19°24'E, Suwałki 54°08' N-22°57' E, Przemyśl 49°48' N-22°46' E). The variability of several indices conditioning the growth of plant vegetation was determined. Increase in the air temperature in the first three quartiles of the calendar year was detected. During November.December period the opposite tendencies were noted, however not statistically significant.The length of winter period shortened considerably, especially in western Poland. The warming caused substantial rise in potential evapotranspiration, the largest in April, May and August. Summer period has extended during the last five decades. Cumulative temperatures, calculated with respect to the 10°C threshold also revealed an upward tendency. Sunshine duration totals increased - the highest increase was observed in the western Poland in May.June season. The length of vegetation season (> 5°C) did not change significantly during the 50-year period. There was only a slight tendency towards the earlier occurrence of both beginning and ending date of this season. The climate transformation in Poland, related undoubtedly to global warming, indicates possible intensification of vegetation growth due to more favourable solar and thermal conditions.

The increasing role of perennials in ornamental nurseries requires the elaboration of efficient and accurate irrigation control of this specific group of plants. The experiment was conducted in 2015 in Research Institute of Horticulture, in Skierniewice. The aim of the study was to determine the water requirements and designate the specific evapotranspiration crop coefficient Kc of several perennials, commonly grown in Polish ornamental nurseries. Water requirements of perennials were evaluated using weighing lysimeters. At the same time the recorded climate parameters allowed to calculate the potential evapotranspiration (ET0). Lysimeter measurements and meteorological data allowed determine specific to each species crop coefficient (Kc). The Kc values were determined by dividing ETc by ET0. The obtained results showed that irrespectively of plant growth phase there is strong correlation between climate parameters and real crop evapotranspiration (ETc) of six evaluated perennials: Anemone hupehensis ‚Prinz Heinrich’, Echinacea purpurea ‘Guava Ice’, Hemerocallis, ‘Sandra Elisabeth’, Salvia nemorosa ‘Mainacht’ and Veronica spicata ‘Royal Candles Glory’. The Kc coefficients of all species were changed during the growth season and increased according to plant development and percentage of ground coverage of soil in the lysimeter by leaves. The strong, positive correlation was shown for daily and hourly calculated crop evapotranspiration and potential evapotranspiration (ET0) obtained from weather station. Determination of crop coefficients for ornamental perennials is essential for precise calculation of water doses and irrigation controlling in the nurseries.
