“…Nevertheless, a gradual increase in areas of soybean cultivation is observable [1,4]. Soybean seeds should be sown in soil with a temperature of at least 12 • C, and the average temperature during the vegetation period of this species should be at least 15 • C [6]. It is believed that the optimal time for sowing soybean seeds in Poland is when the top layer of soil reaches a temperature of 10 • C; i.e., in the period from 21 April to 10 May [4,7,8].…”

Soya, one of the most economically important crops, is sensitive to periodic water deficits, which, because of climate change, are becoming more and more common in central Europe. The goal of this study was to estimate the water requirements of soybean from 1981 to 2020 in four provinces of central Poland and the rainfall deficits affecting soybean cultivation; the study also evaluates rainfall water use efficiency for soybean cultivated in production fields to investigate the future necessity of supplemental irrigation. Calculations were based on the values of monthly air temperature and the sum of precipitation. Soybean water requirements were calculated using the method of crop coefficients and reference evapotranspiration was estimated using the Blaney–Criddle approach. Crop water requirements were defined as potential evapotranspiration. Precipitation deficits for soybean were estimated using the Ostromęcki method. Water use efficiency was calculated based on rainfall totals and soybean yield in the rainfed fields. It was found that, on average in the central Poland provinces, from 1981 to 2020, the water requirements of soybean in the growing season amounted to 384 mm, and the highest water requirements occurred in June and July. In the studied forty-year period, a significant upward trend in soybean water requirements in central Poland was observed, both from 1 May to 31 August and from 1 June to 31 August. Rainfall deficits in soybean cultivation in central Poland were found from May to August and amounted to 123 mm in normal years (N50%). The rainfall water use efficiency from April to August for soybean cultivated in central Poland on average amounted to 6.6 kg ha−1 mm−1 and varied in individual years and regions. The results of the study indicate the need to develop supplemental irrigation systems for soybean crops cultivated in central Poland and other areas of the world with similar climate conditions to optimize yield and the sustainable use of water resources.

“…The low cultivation area of soybean is mainly due to the high climatic requirements of this species, i.e. sowing in soil at temperature at least of 12°C and the average air temperature during crop growth not lower than 15°C [FLOREK et al 2012;JERZAK et al 2012]. According to the most recent source, the optimal date for sowing soybean in Poland is from the last decade of April till the first decade of May, when the top layer of the soil reaches temperature of 10°C [COBORU 2021;DORSZEWSKI et al 2019;Polska… 2021].…”

According to the SRES A1B climate change scenario, by the end of the 21st century temperature in Poland will increase by 2-4°C, no increase in precipitation totals is predicted. This will rise crop irrigation needs and necessity to develop irrigation systems. Due to increase in temperature and needs of sustainable agriculture development some changes in crop growing structure will occur. An increase interest in high protein crops cultivation has been noted last years and further extension of these acreage is foreseen. Identifying the future water needs of these plants is crucial for planning and implementing sustainable agricultural production. In the study, the impact of projected air temperature changes on soybean water needs, one of the most valuable high-protein crops, in 2021-2050 in the Kuyavia region in Poland was analysed. The calculations based on meteorological data collected in 1981-2010 were considered as the reference period. Potential evapotranspiration was adopted as a measure of crop water requirements. The potential evapotranspiration was estimated using the Penman-Monteith method and crop coefficient. Based on these estimations, it was found that in the forecast years the soybean water needs will increase by 5% in the growing period (from 21 April to 10 September), and by 8% in June-August. The highest monthly soybean water needs increase (by 15%) may occur in August. The predicted climate changes and the increase in the arable crops water requirements, may contribute to an increase in the irrigated area in the Kuyavia region and necessity of rational management of water resources.

“…Over the last decade, Poland, just like other European Union countries, has been carrying out various types of measures aimed at providing food security with regard to fodder protein quite intensely. What is mainly promoted is an increase in the cultivation area of fodder legumes for fodder seeds (Czerwińska-Kayzer, Jerzak and Krysztofiak, 2016;Jerzak and Krysztofiak, 2017;Jerzak and Mikulski, 2017;Majchrzycki, Pepliński and Baum, 2002). In Poland, the legume most commonly cultivated for this purpose was sweet lupine (which includes all varieties of yellow lupine and most varieties of narrow-leaved lupine), but of great importance was also fodder pea i.e.…”

“…However, literature sources report that in Poland the cultivation of fodder legumes for fodder seeds is quite often unprofitable. Subsidies granted for their cultivation significantly increase the level of income from these activities, although it is often relatively low and sometimes negative (Bojarszczuk and Podleśny, 2017;Czerwińska-Kayzer et al, 2016;Jerzak, 2014;Jerzak and Mikulski, 2017;Majchrzycki et al, 2002).…”

The subsidies for legumes introduced in 2010 resulted in an increase in their cul tivation area, including the area of sweet lupine and fodder pea. The cultivation of lupine is usually carried out on soils of the rye complex, similarly to winter rye, while the cultivation of peas -on soils of the wheat complex, like winter wheat. Due to similar soil requirements, legumes compete with cereals for the arable land. However, the cultivation of the former is not considered to be very profitable, even after including direct subsidies for cultivation. The purpose of the paper was to determine the production and economic results from the cultivation of the abovementioned legumes and cereals and to compare the profitability of cul tivation of sweet lupine in relation to winter rye and fodder pea in relation to winter wheat on selected individual farms in Poland in the years 2015-2017. Profitability of cultivation of the plants was determined primarily using the profitability in dex of production, which is a percentage relation of the total value of production (excluding direct subsidies) to the total costs. The measure of profitability was also the income from activity without subsidies and income from activity after including subsidies. In the research, we used data from the AGROKOSZTY system, the Polish FADN system and the Central Statistical Office. Vertical and horizontal analysis of the results was used. It was shown that on average in the years 2015-2017, on farms participating in the study of considered plants, the profit ability of lupine cultivation, expressed by profitability index, was lower than that of rye, and pea cultivation was slightly higher than that of wheat.
