The significance of the equations of trends water needs of Jerusalem artichoke and their tendencies in the reference and in forecast years.

Most scenarios of climate change in Poland predict an increase in air temperature in the coming years. However, no significant increase in precipitation is forecast. Therefore, an increase in the water needs of plants should be expected, which requires the development of irrigation systems. To precisely determine the schedule of crop irrigation, it...

... the analyzed growing season of Jerusalem artichoke (i.e., from 21 May to 30 September), an upward trend in potential evapotranspiration (i.e., water needs of Jerusalem artichoke) was found (Table 5). However, the trend of time variability of water needs was insignificant in both the reference and forecast periods. ...Similar publications

JA (Jerusalem artichoke) cultivars react differently to mineral fertilization. Hence, the aim of this study was to assess the effect of mineral fertilization on the yield and yield structure of this species in terms of its aboveground biomass. The research was based on a field experiment carried out in 2016–2018 in Central and Eastern Poland using...

... Supplemental irrigation is one of them. A number of studies have already confirmed the fact that along with the deepening of global warming, the importance of supplementary irrigation in Poland is increasing, especially in northcentral Poland, including the Bydgoszcz region [15,16,21,[42][43][44][45][46][47][48][49][50][51]. It is believed, however, that both the amount of water used for the irrigation of agricultural crops and the area of irrigated crops in Poland will depend mainly on the economic conditions of agriculture and its development strategy and to a much lesser extent on climatic conditions [16]. ...
The Bydgoszcz region (Poland) is located in an area with a very high demand for supplementary irrigation during the vegetation period of plants. The projected global warming will bring a rise in the water needs of crops, and thus a further increase in irrigation needs. The goal of the study was an attempt to estimate the water needs of sweet cherry trees in 2021–2050 (forecast period) in the region of Bydgoszcz. The years 1981–2010 were adopted as the reference period. The water needs of sweet cherry trees were calculated on the basis of air temperature using the Treder method, in which water needs are equated with the potential evapotranspiration of a given fruit tree species. It was found that in the growing season of the forecast period, the relative diversity of sweet cherries’ water needs was relatively small (7%). The highest variability of monthly water needs was in April, May, and June. The seasonal water needs amounted to 573 mm, with very high monthly water needs noted in July (139 mm) and August (134 mm). A significant trend of the time variability of water needs was calculated only in August. During this month, it is predicted that the water needs will rise by 5 mm in each subsequent decade. These results will be helpful in the design of sweet cherry irrigation treatments.
