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 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.

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.
