The aim of the present research was to compare the water requirements of grapevine in the regions of Bydgoszcz and Wrocław in the forty-year period between 1976 and 2015. In the research the authors used the mean monthly temperature values (°C) and monthly precipitation (mm) for the May-September period in the years 1976-2015. The meteorological data for the Bydgoszcz region was derived from standard meteorological measurements performed at the Experiment Station at Mochełek, and analysed at the Department of Land Reclamation and Agrometeorology of the UTP University of Science and Technology in Bydgoszcz. The meteorological data for the Wrocław region were provided by the Swojec experiment station of the Wrocław University of Environmental and Life Sciences. The grapevine water requirements were determined as optimal precipitation assumed by Kemmer and Schulz. It has been found that the grapevine water requirements in 1976-2015, expressed as the optimal annual precipitation according to Kemmer and Schulz, were higher in the Wrocław region than in the Bydgoszcz region and they amounted to 469.3 mm and 435.8 mm, respectively. The grapevine water requirements in both regions in the forty-year period under study showed a growing tendency. A larger increase in grapevine water requirements (27.5-28.0 mm per decade) occurred in the Wrocław region. The estimates show that during the forty-year period (1976-2015) the precipitation deficits in grapevine growing in the May-September period occurred in 11 years in the Bydgoszcz region and in 9 years in the Wrocław region.

The aim of the present research has been an attempt at estimating the water requirements of sweet cherry tree in 2016-2050 in the Bydgoszcz region drawing on the forecast temperature changes. The paper draws on the forecasting of mean monthly temperature for the Bydgoszcz region in 2011-2050 according to the climate change scenario for Poland SRES: A1B (Bąk, Łabędzki 2014). The water requirements of the sweet cherry tree have been determined based on the indispensable precipitation determined by Kemmer and Schulz. The water requirements were calculated for the period January through December and May through September for each year in the 35-year period (2016-2050). The reference period was made up by a 35-year period immediately preceding it (1981-2015). In 2016-2050 in the Bydgoszcz region, in the light of the forecast temperature change scenarios, one can expect an increase in the water requirements of the sweet cherry tree. Determined with the Kemmer and Schulz method, the required annual (January-December) optimal total precipitation will increase for the sweet cherry tree from 532 mm to 746 mm (by 214 mm, which accounts for 40%). The optimal precipitation trend equations show that in the reference period (1981-2015), calculated with the Kemmer and Schulz number, the optimal annual precipitation was increasing in the sweet cherry tree in each pentad by 2.4-3.0 mm. In the forecast period (2016-2050) the water requirements will increase, however, in each pentad within a much greater range, from 13.0 to 14.5 mm. In the summer period (May through September) determined by Kemmer and Schulz, the total precipitation optimal for the sweet cherry tree, expressing the water requirements, in 2016-2050 will increase by 107 mm.

The aim of the present research has been an attempt at evaluating the water requirements of plum trees over 2016-2050 in the Bydgoszcz region drawing on the forecast changes in temperature. The paper draws on the forecasting of mean monthly temperature for the Bydgoszcz region in 2011-2050 according to the climate change scenario for Poland SRES: A1B (Bąk, Łabędzki 2014). The water requirements of the plum tree have been determined based on the indispensable precipitation determined by Kemmer and Schulz. The water requirements were calculated for the period January through December and May through September for each year in the 35-year period (2016-2050). The reference period was made up by a 35-year period immediately preceding it (1981-2015). In 2016-2050 in the Bydgoszcz region, in the light of the forecast temperature change scenarios, one should expect an increase in the water requirements of the plum tree. The annual (January-December) optimal total precipitation determined according to the Kemmer and Schulz method will increase for the plum tree from 712 mm to 807 mm (by 95 mm, which accounts for 13%). The optimal precipitation trend equations show that in the reference period (1981-2015), calculated, drawing on the Kemmer and Schulz number, the optimal annual precipitation was increasing in the plum tree in each pentad by 7.1-7.5 mm. In the forecast period (2016-2050) the water requirements will increase, however, in each pentad within a much smaller range, from 2.6 to 3.0 mm. In the summer period (May-September) determined by Kemmer and Schulz, the total precipitation optimal for the plum tree, expressing water requirements, in 2016-2050 will increase by 47 mm.

The aim of the present research has been an attempt at evaluating the water requirements of pear trees over 2016-2050 in the Bydgoszcz region drawing on the forecast changes in temperature. The paper draws on the forecasting of mean monthly temperature for the Bydgoszcz region in 2011-2050 according to the climate change scenario for Poland SRES: A1B (Bąk, Łabędzki 2014). The water requirements of the pear tree have been determined based on the indispensable precipitation determined by Kemmer and Schulz. The water requirements were calculated for the period January through December and May through September for each year in the 35-year period (2016-2050). The reference period was made up by a 35-year period immediately preceding it (1981-2015). In the period 2016-2050 in the Bydgoszcz region, in the light of the temperature change scenarios made, one should expect an increase in the water requirements of the pear tree. Determined with the Kemmer and Schulz method, the required optimal annual (January-December) precipitation will increase for the pear tree from 624 mm to 771 mm (by 147 mm, namely by 24 %). The optimal precipitation trend equations show that in the reference period (1981-2015), calculated with the Kemmer and Schulz numbers, the optimal annual precipitation was increasing in the pear tree in each pentad by 5.1-5.5 mm. In the forecast period (2016-2050) the water requirements will increase, on the other hand, in each pentad within a much greater range (7.5-8.4 mm). In, determined by Kemmer and Schulz, summer period (May-September), the total precipitation, expressing water requirements, optimal for the pear tree in 2016-2050 will increase by 73 mm.

The reference period was made up by a 35-year period immediately preceding it (1981-2015). In 2016-2050 in the Bydgoszcz region, in the light of the forecast scenarios of changes in temperature, one should expect an increase in water requirements of the peach tree. Determined according to the Kemmer and Schulz method, the required optimal annual (January-December) precipitation will increase for peach from 486 mm to 612 mm (by 126 mm, which accounts for 26%). The optimal precipitation time variation trend equations show that in the reference period (1981-2015), calculated based on the Kemmer and Schulz number, the optimal annual precipitation was increasing in the peach tree in each pentad by 4.4-4.8 mm. In the forecast period (2016-2050) the water requirements of the peach tree will be increasing in each pentad in a greater range - from 6.4 to 7.2 mm. In the summer period (May-September) determined by Kemmer and Schulz, expressing water requirements, the total precipitation optimal for the peach tree in 2016-2050 will increase by 63 mm.

The reference period was made up by a 35-year period immediately preceding it (1981-2015). In the 2016-2050 period in the Bydgoszcz region, in the light of the anticipated temperature change scenarios, one can expect increased grapevine water requirements. Determined with the Kemmer and Schulz method, the required optimal annual (January-December) precipitation will increase for the grapevine from 440 mm to 576 mm (by 136 mm, namely by 31 %). The optimal precipitation trend equations demonstrate that in the reference period (1981-2015), calculated with the Kemmer and Schulz, the optimal annual precipitation was increasing in grapevine in each pentad by 2.2-2.6 mm. In the forecast period (2016-2050) the water requirements will increase, however, in each pentad in a much greater range (8.0-8.9 mm). In the summer period (May-September) determined by Kemmer and Schulz, the total precipitation optimal for the grapevine, expressing the water requirements, in 2016-2050 will increase by 68 mm.

The aim of the present research has been an attempt at evaluating the water requirements of apple trees over 2016-2050 in the Bydgoszcz region drawing on the forecast changes in temperature. The paper draws on the forecasting of mean monthly temperature for the Bydgoszcz region in 2011-2050 according to the climate change scenario for Poland SRES: A1B (Bąk, Łabędzki 2014). The water requirements of the apple tree have been determined based on the indispensable precipitation determined by Kemmer and Schulz. The water requirements were calculated for the period January through December and May through September for each year in the 35-year period (2016-2050). The reference period was made up by a 35-year period immediately preceding it (1981-2015). In the 2016-2050 period in the Bydgoszcz region, in the light of the temperature change scenarios, one could expect increased apple-tree water requirements. Determined with the Kemmer and Schulz method, the required annual (January-December) optimal precipitation will increase for the apple tree from 681 mm to 849 mm (by 168 mm, namely by 25 %). The optimal precipitation trend equations show that in the reference period (1981-2015), calculated with the Kemmer and Schulz numbers, the optimal annual precipitation for the apple tree was increasing in each pentad by 5.8-6.3 mm. In the forecast period (2016-2050) the water requirements will increase, however, in each pentad in a much greater range; from 8.5 to 9.6 mm. In the summer period (May-September) determined by Kemmer and Schulz, the optimal precipitation, expressing the water requirements, for the apple tree in 2016-2050 will increase by 84 mm.
