The aim of the study was to evaluate the tourism and recreational space of Lubaczowski County in Poland. The evaluation was carried out by using a multidimensional comparative analysis while taking into account tourism assets, transportation accessibility, natural environmental protection, the level of tourism infrastructure development as well as the factors contributing to an opportunity for the development of tourism via investment attractiveness (the level of infrastructure development, population relations, or the financial situation of the communes). Moreover, a questionnaire survey was carried out among the inhabitants with the aim of learning of their opinions on tourism assets and tourism infrastructure development in the commune. The study is supplemented by a comparison of the analysis results with the results of a questionnaire survey conducted among the Lubaczowski County inhabitants, which concerned the county’s attractiveness to tourists. Based on the evaluation and the questionnaire survey results, it was found that urban communes of Lubaczów and Horyniec-Zdrój had the best conditions for tourism development. These communes took the first (0.701) and the second (0.492) position in the ranking, respectively. Both communes are characterised by well-developed accommodation and catering facilities, a wealth of natural assets, and good transportation accessibility. For the better development of tourism in the county, it is necessary to take appropriate measures aimed at eliminating limitations and highlighting the strengths. To this end, it will be necessary to incorporate measures aimed at enhancing the quality of tourism infrastructure development and establishing a marketing plan that will allow tourists to learn about the tourism assets of the commune into the strategy for commune development.

The purpose of the paper is to analyze the spatial variability of precipitation in Poland in the years 1981–2010. The av-erage annual rainfall was 607 mm. Precipitation in Poland is characterized by high spatial and temporal variability. The lowest annual precipitation was recorded in the central part of the country, where they equaled 500 mm. The highest annual precipitation totals were determined in the south, equaling 970 mm. The average precipitation in the summer half-year is 382 mm (63% of the annual total). On the basis of data from 53 climate stations, maps were made of the spatial distribution of precipitation for the period of the year and winter and summer half-year. The kriging method was used to map rainfall distribution in Poland. In the case study, cross-validation was used to compare the prediction performances of three periods. Kriging, with exponential type of semivariogram, gave the best performance in the statistical sense. Their application is justices especially in areas where landform is very complex. In accordance with the assumptions, the mean prediction error (ME), mean standardized prediction error (MSE), and root mean-square standardized prediction error (RMSSE) values are approximately zero, and root-mean-square prediction error (RMSE) and average standard error (ASE) reach values well below 100.

Yield and the course of crop vegetation are the result of the interaction between the level of cultivation technology and the course of meteorological conditions, which are a variable production factor. The aim of the study was to quantify the effect of meteorological conditions on the course of development stages and yield of winter wheat cultivated in two technological variants (A1 – medium-intensive and A2 – intensive). The paper uses data on yield and timing of winter wheat development stages from four Experimental Stations for Variety Testing (Pol. Centralny Ośrodek Badania Odmian Roślin Uprawnych – COBORU) experimental stations from 2007–2016 located within the Upper Vistula and Upper Oder River basins. To determine the dependence of the length of development stages of winter wheat on the values of selected meteorological elements, the linear regression metod, correlation coefficient. It was found that the lengths of the selected developmental stages are positively correlated with air temperature and negatively correlated with the sum and number of days with precipitation in these stages. A 1°C increase in air temperature resulted in a shortening of the shooting – heading and heading – full maturity periods by 2.5 and 2.8 days respectively. An increase of 100 mm of precipitation in the periods sowing – full maturity and heading – full maturity resulted in an increase of these periods by 5 and 10 days. Increasing the number of days with precipitation by 10 days in the sowing – full maturity and heading – vax maturity stages resulted in extending these stages by 4.1 to 4.4 and 7 to 7.5 days for the A1 and A2 cropping technologies, respectively.
